EXECUTIVE
SUMMARY: THE VALUE OF HIGHER EDUCATION
•
Higher
education provides considerable value to individuals, the economies where
educated individuals work and live, and society in general.
Private
Returns
•
Individual
earnings are strongly related to educational attainment. People who have
completed high school earn more than those who have not; people with a
bachelor’s degree earn more than those with only a high school diploma; and
those with a graduate education earn more than those with only an undergraduate
education.
•
Average
annual earnings of individuals with a bachelor’s degree are more than 75
percent higher than the earnings of high school graduates. These additional
earnings sum to over $1 million over a lifetime.
•
The
differential in earnings based on educational attainment has increased over
time. For example, for full-time male workers between the ages of 35 and 44,
the earnings premium associated with having a bachelor’s degree versus a high
school diploma has risen from 38 percent in the 1980-84 period to 94 percent in
2000-03.
•
The
benefits to an individual from a university education vary with the quality of
the institution attended. Those who graduate from an elite university earn
substantially more than those who graduate from a lower-quality institution.
•
To
properly assess the economic value of a college education, the benefits
realized in terms of higher future earnings must be discounted to adjust for
the time value of money. The discounted earnings must then be weighed against
the full costs of acquiring a college education including not only the tuition
paid by the student, but the earnings foregone while the student is in college
and the appropriations of state and local governments. When these calculations
are made, the benefits of a college education are seen to be more than three
times as large as the costs.
•
If
the value of a college education is expressed on the same basis as the return
on a financial investment, the net return is on the order of 12 percent per
year, over and above inflation. This compares favorably with annual returns on
stocks that historically have averaged 7 percent.
•
Despite
the very high return on investment for the time and money spent on attaining a
college degree, only one-quarter of the U.S. adult population has at least a
bachelor’s degree. Academic ability and information barriers limit the number
of individuals who attain a university degree.
•
Financial
barriers to the completion of a bachelor’s degree exist but government programs
that promote access have been effective.
•
The
academic ability of the individual — which is shaped throughout his/her life by
a variety of family and environmental factors — and the values and goals of the
individual — which are strongly influenced by the education of his/her parents
— are important determinants of educational attainment.
Societal
Benefits
•
Social
benefits of a workforce with greater educational attainment and skills can be
traced to the enhanced worker productivity associated with greater educational
attainment. These productivity gains translate into higher output and incomes
for the economy. 1
•
Non-monetary
societal benefits in regions with high proportions of college graduates include
lower crime rates, greater and more informed civic participation, and improved
performance across a host of socioeconomic measures.
•
Intergenerational
social benefits may be very large as degree attainment today translates into
higher probabilities of degree attainment in future generations.
•
Empirical
work in econometrics suggests that after controlling for differences in
amenities and individual wages, an increase in the share of college graduates
in the labor force leads to significant increases in productivity and wages for
all workers.
•
A
portion of this significant wage effect is attributable to spillovers that
result from productivity gains. Simulations for Arizona using conservative
estimates of these spillovers suggest that combining spillovers and individual
benefits realized from a four-year college degree, degreed workers account for
gross lifetime earnings that total $1.6 to $1.9 million more than workers with
only a high school diploma.
•
Accounting
for costs of education and the time value of money, discounted lifetime net
benefits from a university degree — including combined individual and societal
benefits exceed $600,000 per worker —a combined internal rate of return of
about 16 percent.
•
A
statewide simulation designed to measure the impact of raising the share of
college graduates in the labor force by 0.2 percent (the median annual rate of
increase observed in the econometric studies) that used Arizona data on
educational costs and wages reveals that total costs match benefits after about
11 years. After accounting for the time value of money, the payback period is
about 13 years and the net discounted benefits (benefits less costs) that
accrue after 20 years are estimated at $364 million.
•
Numerous
estimates of the rate of return to investments in education prevail in the
literature. Results suggest that significant portions of economic and job
growth are attributable to human capital while discernible evidence of
non-monetary benefits also is seen empirically.
Higher
Education Enrollment and Finance
•
Enrollment
in degree-granting institutions of higher education in Arizona as a percentage
of the state’s population was about equal to the national average in 2003. Many
Arizonans attend community colleges but do not complete a four-year degree.
•
Combining
both public and private institutions, total revenues and expenditures per
student at Arizona institutions of higher education were far below the national
averages in 2003, among the least in the nation. Among public institutions,
Arizona’s per student higher education revenues and expenditures were not as
far below average, but still ranked among the bottom 10 states in the nation.
•
Public
financial support for higher education, as measured by government
appropriations, was marginally higher in Arizona than the national per student
average in 2003, with Arizona ranking just above the middle of the states.
However, tuition and fees and other revenues were far below the per student
average.
•
Increases
in public support for higher education per student have been nearly equal in
Arizona and the nation. But, support nationally has not kept pace with real per
capita GDP growth and real per capita GSP growth in Arizona has substantially
outstripped growth in public support for higher education on a real per student
basis.
2
Educational
Attainment
•
Arizona
ranks in the middle of the states on the percentage of its residents possessing
a bachelor’s degree, slightly below the U.S. average. However, educational
attainment has increased less in Arizona than the national average in recent
decades.
•
Arizona
compares less favorably among labor force participants, since the state’s
overall educational attainment is bolstered by highly educated retirees who
migrate to the state at retirement.
•
The
educational attainment of young adults in Arizona is substantially below the
national average.
•
Among
those educated in Arizona and among immigrants to the state, educational
attainment is relatively low. In contrast, the attainment of interstate
migrants is considerably higher.
Geographic
Distribution of the University-Educated Population
•
To
realize a high share of college graduates in its population, a region must
either graduate a large number of people from local institutions of higher
education or attract college graduates from other regions.
•
Labor
force participants with university degrees are highly mobile in terms of their
residence. Thus, the number of university graduates from local institutions of
higher education is not necessarily highly related to the number of college
graduates living in a community.
•
In
any community, the retention of locally educated individuals and the attraction
of highly educated people from other regions are heavily dependent on the
availability of job opportunities appropriate for those with college degrees.
Urban and natural amenities also are important to the attraction and retention
of college graduates.
•
National
studies indicate that a statistically significant relationship exists between
the number of new college graduates in a state and average educational
attainment in the state’s adult population. But the strength of this
relationship appears modest.
•
Using
national data, studies find that if an additional 100 college-bound students
choose to attend college in a given state, the long-run effect of raising the
college-educated workforce in that state will be only 5-to-10 workers.
Nationally, it is college attendance per se, not where students choose to
attend, that is the crucial determinant of educational attainment in a given
workforce. Educated workers migrate in search of occupations that align with
their skill sets.
Policy
Issues
•
Despite
the high rate of return to higher education, only one-quarter of the U.S.
population has obtained a four-year college degree. Underinvestment in higher
education occurs.
•
Impediments
to college degree attainment include family financial constraints, lack of
academic skills necessary for success, and an apparent lack of knowledge or
belief in the large effect that a college education has on an individual's
future earnings.
•
While
policy interventions designed to address financial access are abundant, more
attention may be needed to address the information and ability concerns
•
Evidence
does not exist that local production of graduates, in isolation, will be an
effective economic development strategy. A portfolio approach — that
incorporates higher education and that is aimed at quality workforce
development, quality public infrastructure, an emphasis on quality of life and
amenities, and efforts to attain and maintain business climate conducive to
attracting quality employment opportunities — may yield the highest returns.

Overview
Higher
education provides considerable value to individuals, to the economies where
educated individuals live and work, and society in general. Economies that have
experienced substantial investment in either private or public institutions of
higher learning have realized considerable growth and prosperity.
Higher
education influences economic well-being in three ways. First, the direct
expenditures by the institutions, their employees, and their students impact
the local economy. This spending multiplies through the local economy until the
monies are used to purchase goods and services from outside the local area.
Such economic impacts have been estimated at many institutions of higher
education. For example, the total impact of Arizona State University was
estimated at 37,000 jobs resulting in more than $1 billion in wages each year.
However, only the higher education revenues originating from outside the local
economy — such as from National Science Foundation grants — and the spending of
out-of-state students and their parents can be considered a unique economic
impact of higher education.
Second,
higher education provides financial and non-financial benefits to the
individual who pursues an advanced education and to society in general. The
average earnings of individuals are closely related to their educational
attainment. In particular, those with a bachelor’s degree earn substantially
more than even those with some college education. Relative to those with a
bachelor’s degree, a postgraduate degree provides nearly as large a boost in
earnings. In addition, society benefits from an educated populace. The average
wage — even for those workers who do not possess much educational attainment —
is higher in communities with a substantial proportion of highly educated
workers. Various other benefits to society also are realized from enhanced
educational attainment, such as a lower crime rate. This report provides a
detailed analysis of the impacts of enhanced educational attainment.
Third,
institutions of higher education are increasingly focused on knowledge
creation. Thus, universities are sources of key research and development
innovations that simultaneously can be beneficial to society and conducive to
economic growth. This topic will be discussed in a future report of the Productivity
and Prosperity Project.
Benefits
to Individuals of Enhanced Educational Attainment
Individual
earnings are directly related to educational attainment. Those with a high
school diploma earn more than those who did not graduate from high school,
those who received some college credits earn more than those whose education
ended with a high school diploma, those with a bachelor’s degree earn more than
those with some college credits, and those with a graduate degree earn more
than those with a bachelor’s degree as their highest attainment. In particular,
those with a bachelor’s degree earn substantially more than those with some
college credits. A postgraduate degree provides an additional boost in
earnings.
Earnings
vary widely with educational attainment. For example, 2000 census data revealed
that average annual earnings of individuals with a bachelor’s degree was from
74 to 87 percent higher (depending on age) than the earnings of individuals
whose maximum educational attainment was a high school diploma. Over a career, an
individual with a bachelor’s degree earns on average in excess of $1 million
more than a counterpart with only a high school diploma. Based on a
cost-benefit analysis over a person’s working life, the expected net return
from an individual’s payment of tuition and fees and foregone income while
obtaining a bachelor’s degree is in excess of 11 percent, a rate that compares
favorably with real returns on most financial assets.
4
The
differential in earnings based on educational attainment has increased over time.
For example, for full-time male workers between the ages of 35 and 44, the
earnings differential between those having a bachelor’s degree and those with a
high school diploma has risen from 38 percent in the 1980-84 period to 94
percent in 2000-03. This rising differential constitutes the principal evidence
for the emerging “knowledge economy.”
The
benefits to an individual from a university education vary with the quality of
the institution attended. In studies of universities, quality is defined by measures
such as average faculty salaries and average test scores of entering freshmen.
These studies generally find that the quality of the institution has a
significant effect on the earnings of graduates later in life. Those who
graduate from elite institutions earn substantially more than those who
graduate from lower-quality institutions. Some evidence also exists that the
value of a college education is higher for those who attend graduate
degree-granting research institutions, such as Arizona State University.
A
long-standing concern of researchers has been that individuals who are
successful in school tend to have high cognitive and non-cognitive abilities
and these abilities would have provided them with greater earnings capacity
whether or not they chose to become highly educated. While controlling for
innate ability when studying the effects of education on earnings is difficult,
the consensus view of labor market researchers is that the effects of “ability
bias” are small in data comparing educational attainment to earnings. The true
benefit of educational attainment is not much below the estimate observed in a
simple cross-tabulation of earnings and education.
Despite
the very high return on investment for the time and money spent on attaining a
college degree, only one-quarter of the U.S. adult population (28 percent of
those 25-to-34 years old) has at least a bachelor’s degree. Three barriers —
financial, ability, and information — limit the number of individuals who
attain a university degree.
The
available evidence suggests that no more than 8 percent of the youth population
fail to complete college simply because of a lack of financial resources,
undoubtedly due in large part to government programs that help to ease
financing burdens. A review of the literature reveals that the academic ability
of the individual, which is shaped throughout his/her life by a variety of
family and environmental factors, and the values and goals of the individual,
which are strongly influenced by the education of his/her parents, are the main
determinants of educational attainment. A lack of information on the costs and
benefits of higher education may underlie these factors.
Societal
Benefits of Enhanced Educational Attainment
In
regions with a highly educated labor force, all workers — not just those with
advanced educational achievements — receive higher wages than their
counterparts in regions with lesser educational attainment. These monetary
benefits have been measured using widely varying techniques, such as by
examining the economic performance of regions with different shares of college
graduates in the labor force.
Recent
research indicates that significantly higher wages are present in regions with
greater shares of college graduates in the labor force. An extensive
econometric analysis found that after controlling for other factors, a 1
percentage point increase in the labor force share of college graduates in a
metropolitan area yields a 1.9 percent increase in the wages for high school
dropouts, a 1.6 percent gain in the wages of high school graduates, and a 0.4
percent rise in the wages of the graduates themselves, over and above the
average wage differential between
5
individuals
with college degrees and those with less education. One explanation for these
higher wages in areas with higher educational attainment is the enhancement of
productivity that comes with a workforce with more education and skills.
In
a simulation that applied these wage estimates to Arizona data, a conservative
estimate of the portion of this annual wage appreciation that occurs due to
social spillovers is $16,000 per university graduate. Adding social spillovers
to the more than 11 percent expected net return received by individuals who
have at least a bachelor’s degree increases the net return to nearly 16
percent.
A
second simulation was designed to measure the aggregate social costs and
benefits of a program to permanently increase the labor force share of
university graduates by 0.2 percent (the average annual increase measured in
the econometric analysis) in Arizona, which amounts to about 4,500 workers as
of 2005. After accounting for the time value of money and comparing the
monetary costs and benefits, the payback period was estimated to be 13 years.
After 20 years, discounted social benefits exceed discounted social costs by
$364 million. The net benefits would be higher if the costs were reduced by
providing incentives for students to graduate in a timely fashion and to seek
employment in Arizona after graduation from the university.
In
addition to the monetary societal benefits of enhanced educational attainment,
regions with greater shares of educated workers, especially highly educated
workers, enjoy lower crime rates, have fewer demands placed upon social
services, greater civic participation, and improved personal health. These
benefits accrue to subsequent generations.
Empirical
Data on Higher Education Enrollment and Finance
Enrollment
in degree-granting institutions of higher education in Arizona as a percentage
of the state’s population was about equal to the national average in 2003. The
Arizona figure was higher than the national average at private for-profit
institutions, slightly greater than the national average at public
institutions, but considerably below average at private not-for-profit
institutions.
Total
revenues and expenditures per student at Arizona institutions of higher
education were far below the national averages in 2003, among the least in the
nation. Among public institutions, Arizona’s per student higher education
revenues and expenditures were not as far below average, but still ranked among
the bottom 10 states in the nation.
The
ability to pay for education is below average in Arizona due to the state’s
subpar incomes. Thus, the state’s higher education revenues and expenditures
per student adjusted for income were not as far below the national average in
2003. Among public institutions, Arizona’s per student revenues and
expenditures were close to the national average, ranking near the middle of the
states.
Public
financial support for higher education, as measured by government
appropriations, was marginally higher in Arizona than the national per student
average in 2003, with Arizona ranking just above the middle of the states.
Adjusted by the state’s ability to pay, public support for higher education in
Arizona was considerably higher in 2003 than the national average.
Increases
in public support for higher education per student have been nearly equal in
Arizona and the nation. However, the increases have not been as great as gains
in the ability to pay, particularly in Arizona. Support nationally has not kept
pace with real per capita GDP growth and real per capita GSP growth in Arizona
has substantially outstripped growth in public support for higher education on
a real per student basis.
6
Empirical
Data on Educational Attainment
As
measured by the percent of the population 25 years and older with at least a
bachelor’s degree, educational attainment in Arizona is near average. Arizona
ranked 25th among the states according to the 2000 census, with 23.5 percent
possessing a bachelor’s degree, slightly below the U.S. average of 24.4
percent.
However,
Arizona compares less favorably among those in the labor force, since the
state’s overall educational attainment is bolstered by highly educated retirees
who migrate to the state at retirement. The educational attainment of young
adults (especially those than 35 years of age) in Arizona is considerably lower
than the national average, while the attainment of those 65 or older is higher
than average. The comparatively low attainment of young adults reflects both
the below-average achievement of children educated in Arizona and the strong
net in-migration of young, poorly educated people.
Among
those born in Arizona and living in the state in 2000, the percentage of those
25 or older with a bachelor’s degree was only 18 percent, just half of the
figure of Arizona residents born elsewhere in the United States. Among those
born in another country but living in Arizona in 2000, the share with a
university degree was slightly higher than that of Arizona natives.
Educational
attainment has increased in recent decades in every state. This has occurred
primarily because of the deaths of the less-educated older generations.
Educational attainment among young adults has increased only a little.
Arizona’s ranking among the states on the percentage with a bachelor’s degree
declined between 1980 and 2000, from 19th in 1980 to 24th in 2000. The state
ranked just 39th on the change in educational attainment between 1980 and 2000.
The
Geographic Distribution of the University-Educated Population
For
a region to realize the benefits from a highly educated populace, it must be
able to either achieve an adequate number of college graduates at its local
institutions of higher education or attract such individuals from other
regions. National data reveal considerable labor force migration of college
graduates. Thus, the number of university graduates from local institutions of
higher education is not necessarily highly related to the number of college
graduates living in a community.
The
retention of locally educated individuals and the attraction of highly educated
people from other regions are heavily dependent on the availability of job
opportunities appropriate for those with college degrees. Urban and natural
amenities also are important to the attraction and retention of college
graduates. Business climates that attract businesses with quality opportunities
that require the skills of an educated workforce are obviously a key
determinant.
National
studies indicate that a statistically significant relationship exists between
the number of new college graduates in a state and average educational
attainment in the state’s adult population. But the strength of this
relationship appears modest. Studies find that if an additional 100
college-bound students choose to attend college in a given state, the long-run
effect of raising the college-educated workforce in that state will be only
5-to-10 workers. Nationally, it is college attendance per se, not where
students choose to attend, that is the crucial determinant of educational
attainment in a given workforce. Educated workers migrate in search of
occupations that align with their skill sets.
7
Public
Policy Issues
A
primary conclusion of this report is that college education yields high rewards
that accrue to individuals and to the communities where they ultimately find
employment. Policies that eliminate barriers (informational, ability, or
financial) and result in tangible increases in the number of degree holders are
interventions that should be pursued. Considerable effort has already been
undertaken to alleviate financial barriers and these efforts have brought
results. Effective policies aimed at increasing both enrollment and degree
completion rates simultaneously could be equally rewarding.
The
barriers pose significant challenges and debate over the efficacy and cost of
alternative policy options will occur, but in the end the potential rewards are
very high. Empirical estimates capturing the magnitude of these rewards are
detailed in this report – including significant monetary returns as well as a
long list of non-monetary returns that continue to yield benefits over generations.
The
availability of local institutions (both public and private) can be encouraged
to help meet the local demands exerted by the explosive growth in Arizona’s
population. National data suggest that more expenditure (both public and
private) is devoted toward the production of college graduates in other states
than take place in Arizona. Public and/or private investments that lead to
tangible increases in degree attainment stand to deliver significant returns to
the students that earn the degrees and to the economies where they ultimately
live and work. And increases in the quality of the education can lead to
greater contributions to individual and societal prosperity.
While
local production is an important component, a narrow policy agenda exclusively
focused on producing more college graduates locally is not likely to be
sufficient in attaining the ultimate goal of increasing the proportion of
productive, highly skilled workers in the labor force. Interventions that
encourage quality job opportunities, amenities that attract businesses that
offer quality opportunities, and a business climate that nurtures
entrepreneurship and innovation are important ingredients. And high quality
local universities can play a key role in crafting this climate. But, broad
public policy initiatives that support a high quality transportation,
energy/water, communication, and education infrastructure will help nurture a
business climate that provides gainful employment opportunities needed to
retain the graduates that are produced locally. Those opportunities also can
serve as a magnet for the mobile set of educated people that are produced each
year across the nation.

OVERVIEW
Higher
education provides considerable value to individuals, economies where educated
individuals reside, and society in general. Economies that have experienced
substantial investment in either private or public institutions of higher
learning have realized considerable growth and prosperity.
Higher
education influences economic well-being in three ways, as illustrated in
Figure 1. First, direct expenditures by the institutions, their employees, and
their students impact the local economy, as shown in panel A of Figure 1. This
spending multiplies through the local economy until the monies are used to
purchase goods and services from outside the local area. Such economic impacts
have been estimated at many institutions of higher education. For example, the
total impact of Arizona State University was estimated at 37,000 jobs resulting
in more than $1 billion in wages each year [L. William Seidman Research
Institute, 2003]. However, only the higher education revenues originating from
outside the local economy — such as from National Science Foundation grants —
and the spending of out-of-state students and their parents can be considered a
unique economic impact of higher education.
Second,
higher education provides financial and non-financial benefits to the
individual who pursues an advanced education and to society in general (see
panel B of Figure 1). The average earnings of individuals are closely related
to their educational attainment. In particular, those with a bachelor’s degree
earn substantially more than even those with some college education. Relative
to those with a bachelor’s degree, a postgraduate degree provides nearly as
large a boost in earnings. In addition, society benefits from an educated
populace. The average wage — even for those workers who do not possess much
educational attainment — is higher in communities with a substantial proportion
of highly educated workers. Various other benefits to society also are realized
from enhanced educational attainment, such as a lower crime rate. This report
provides a detailed analysis of the impacts of enhanced educational attainment.
Third,
institutions of higher education are increasingly focused on knowledge creation
(panel C of Figure 1). Thus, universities are sources of key research and
development innovations that simultaneously can be beneficial to society and
conducive to economic growth. This topic will be discussed in a future report
of the Productivity and Prosperity Project.
The
first two chapters of this report demonstrate the value of higher education.
Chapter I presents the substantial financial benefits to individuals that
result from enhanced educational attainment and examines the reasons why more
people do not pursue higher education given the high rate of return from doing
so. Chapter II demonstrates the value to the economy and to society in general
of a highly educated populace, in the forms of higher wages to all workers,
increased productivity, and nonmonetary benefits to society.
The
next two chapters examine factual data on how Arizona compares to the national
average and to other states on measures of higher education. Chapter III looks
at higher education enrollment and finance, while Chapter IV presents data on
educational attainment. While Arizona falls in the middle of the states on
higher education enrollment (relative to the size of the population) and the
educational attainment of all adults, the educational achievement of labor
force participants is subpar and total revenues per student in institutions of
higher education are far below average.
Given
the benefits of a highly educated workforce and Arizona’s below-average
performance, the last two chapters look at issues regarding the location
decisions of highly educated people. Chapter V reviews the evidence while
Chapter VI presents policy options that might result in enhanced educational
attainment in Arizona.

ENHANCED EDUCATIONAL ATTAINMENT
Summary
•
Individual
earnings are strongly related to educational attainment. People who have
completed high school earn more than those who have not; people with a
bachelor’s degree earn more than those with only a high school diploma; and
those with a graduate education earn more than those with only an undergraduate
education.
•
Average
annual earnings of individuals with a bachelor’s degree are more than 75
percent higher than the earnings of individuals whose maximum educational
attainment is a high school diploma. Over a career, an individual with a
bachelor’s degree earns on average in excess of $1 million more than a
counterpart with only a high school diploma.
•
The

time. For example, for full-time male workers between the ages of 35 and 44,
the earnings premium associated with having a bachelor’s degree versus a high

2000-03.

the time value of money. The discounted earnings must then be weighed against
the full costs of acquiring a college education including not only the tuition

are made, the benefits of a college education are seen to be more than three
times as large as the costs.

Introduction
Education
provides a variety of benefits to students including enhanced social skills,
greater awareness of human achievement, and an appreciation for cultural
diversity. But education is increasingly viewed as an economic investment.
Education provides a student with skills that are valued by employers and
increases lifetime earnings capacity. In this chapter the
11
statistical
evidence on the effect of educational attainment on earnings is examined to
determine the economic rate of return realized when an individual invests in a
college education. Particular emphasis is placed on the value an individual
receives from completing a bachelor’s degree.
In
calculating the return on a college education, this chapter considers as
benefits only the incremental earnings realized by the individual who earns the
college degree. Spillover benefits that accrue to other parties are potentially
significant, but they are not considered until the next chapter of the report.
Following the conventional language used by economists, the return to education
presented in this chapter is referred to as the “private return to education.”
When all benefits are considered, including spillovers received by other
individuals, the calculated return is referred to as the “social return to
education.”
To
determine the economic value of a college education, benefits must be weighed
against the full costs of obtaining that education. These costs include the
tuition payments made by the college attendee, the opportunity costs associated
with earnings foregone while in college, and in the case of a public university
the appropriations of state and local governments. The return on investment
calculated using full costs is a more useful guide for public policy than one
calculated using only the costs incurred by the student. College may represent
a good personal investment for an individual if that education is highly
subsidized by the government. But college is shown to represent a wise use of
society’s resources when the value of the enhanced skills the individual
receives, as measured by increased earnings capacity, exceeds the full resource
costs of providing that education.
The
Relationship Between Earnings and Educational Attainment
The
economic value of educational attainment is apparent from cross-tabulations of
national data on individual earnings and educational attainment (see Table I:1
and the graphical depiction of this table in Figure I:1). Since annual
individual earnings vary with the number of hours worked over the year, the data
are for full-time, year-round workers. The latest data from the Current
Population Survey, for 2002 and 2003, are depicted.
Since
the age of an individual is strongly related to the number of years of work
experience, and earnings rise with work experience, earnings increase with age
regardless of the amount of educational attainment. In addition, in each age
group, earnings increase with educational attainment.
The
positive relationship between education and earnings is unmistakable and
universal. Workers who have completed high school earn more than those who have
not; those with some college earn more than those with only a high school
education; people who have earned a college degree earn more than those with a
partial college education; and those with a graduate degree earn more than
those with only a bachelor’s degree. These relationships hold for all age
groups.
The
earnings premium from a college education was substantial in 2002-03. Workers
in the 30-34 age group earned on average $24,100 or 77 percent more if they had
a bachelor’s degree than if they only had a high school diploma. For workers in
the 40-44 age group, those with a four-year degree enjoyed an earnings premium
of $30,700 or 87 percent relative to high school graduates. For workers of age
50-to-54, those with a bachelor’s degree earned $29,000 or 82 percent more than
those with a high school education.
Earnings
by age and educational attainment for Arizonans are shown in Table I:2 and
Figure I:2. Since the Current Population Survey data are not reliable by state,
these data are from 12
the
2000 Census and refer to earnings in the year 1999. The data are for people who
live in Arizona but who may have been educated anywhere in the world.
The
positive association between education and earnings also is obvious in the
Arizona data. For example, for Arizona workers between the ages of 40 and 44,
those with a bachelor’s degree earned $28,200 or 87 percent more than those
with only a high school education.

Increasing
Benefits from Educational Attainment
The
value of a bachelor’s degree relative to a high school diploma has been
increasing steadily since the early 1980s (see Figure I:3). Looking, for
example, at the 35-44 age group, male workers with a bachelor’s degree earned
38 percent more than those with a high school degree over the 1980-84 period,
but they earned 92 percent more than high school graduates over the 2000-03
period. For women, the college premium rose from 41 percent in 1980-84 to 80
percent in 2000-03. A rising skill premium is evident not only in the earnings
of educated workers but also in the earnings of those with work experience and skills
acquired on the job. These trends seem to reflect a broad-based increase in the
demand for skilled workers and reduced demand for low-skill workers that is
occurring throughout the industrialized world.
Labor
market economists attribute the rise in the education/skills premium to several
factors: the emergence of skill-using technologies (especially those involving
the computer), increased trade with less-developed countries, increased
immigration from labor-abundant countries, and a decline in the importance of
unions. Although the high benefit of additional schooling should eventually
lead to a greater supply of educated workers, the consensus opinion of experts
is that the demand for knowledge workers will continue to grow and the return
to education will remain high into the foreseeable future.
Importance
of College Quality
Several
recent studies attempt to determine whether the earnings benefits of a college
education depend on the quality of the college attended. College quality is
measured either in terms of inputs, such as instructional expenses per student
or average faculty salaries, or in terms of peer quality, using variables such
as the average SAT score of the entering class. The general

15
finding
in these studies is that college quality matters. The gross return on a college
education is significantly higher for elite private colleges than it is for
other institutions.
Two
studies — one by Monks (2000) and another by Black and Smith (2004) — use data
from the National Longitudinal Survey of Youth to match individuals and
institutions. Both also use scores from the Armed Services Vocational Aptitude
Battery (ASVAB) to control for ability. Ability bias is an issue in studies of
college quality since students of higher ability tend to attend higher quality
schools.
In
the Monks study, college quality was measured using selectivity ratings from
Barron’s Profiles of American Colleges. These ratings were based on the
percent of applicants accepted and on the entrance test scores, class rank, and
high school grade point average of the entering class. In addition to the
selectivity ratings, Monks also included variables on institutional control
(public or private) and Carnegie classification (for example, “doctoral/research
universities”). Control variables other than those relating to institutional
type included age, gender, race, and score on the Armed Forces Qualification
Test. The study used annual panel data from 1979 to 1993 to examine the effects
of college characteristics on an individual’s real hourly wages.
Individuals
who graduated from a college rated as “highly or most competitive” earned 15
percent more than someone who graduated from a “competitive” institution. The
wage premium for those who graduated from a “very competitive” college was 8
percent relative to a “competitive” institution. Graduates from public
institutions earned 4 percent less than those from private institutions.
Finally, graduates from graduate degree-granting research institutions earned
14 percent more than graduates from liberal arts colleges.
In
the Black and Smith study, college quality was measured using an index based on
average faculty salary, the average SAT score of the entering class, and the
freshmen retention rate. Other individual characteristics used as controls
included age, race, parental characteristics, and an ability measure
constructed from age-adjusted ASVAB scores. The variable to be explained was
the respondent’s wage in 1998.
For
men, those who graduated from a college in the highest quartile earned 12
percent more than those who graduated from a college in the lowest quartile.
Graduates from colleges in the second-highest quartile earned 5 percent more
than those from the lowest quartile, but the difference was not statistically
significant. There was no discernable difference in the wages of graduates from
the lowest two quartiles.
The
nature of the results for women was similar to those for men, but
quantitatively smaller. Women graduating from colleges in the top quartile
earned only 7 percent more than women who graduated from colleges in the lowest
quartile.
The
Rate of Return from a Bachelor’s Degree
To
assess the economic value of an incremental investment in education, such as
college, the costs of education must be considered and discounting techniques
must be used to properly recognize the full lifetime earnings benefits of
additional education. A formal cost-benefit analysis of a four-year college
education is provided in Table I:3. The analysis is based on nationwide figures
for college costs and the national age-education-earnings data available from
the 2002-03 Current Population Surveys. Separate calculations were made for men
and women.
The
full costs of going to college include tuition and fees paid by the student,
state and local government appropriations in the case of a public university,
and foregone earnings during the time the student is attending college. For
public four-year research institutions, average tuition and fees are approximately
$5,000 per year and government appropriations are around
16
$9,000
per full-time equivalent student per year. For private four-year research
institutions, mean tuition and fees are about $16,000 per year. In this
analysis, a figure of $15,000 is used to represent the annual direct cost of
attending college as an average of the costs of public and private
institutions. Over four years, the total direct costs thus are $60,000. For
someone attending a public university, the personal out-of-pocket expenses are
substantially less than this amount.
Assuming
that college students work only during the summer and earn what a high school
graduate would make, the earnings foregone by a male when attending college are
$17,650 per year, or $70,600 over four years. For women, foregone earnings are
$14,325 per year, or $57,300 over four years.
Benefit
calculations are made assuming the individual is fully employed from age 22 to
65. For men, this assumption may serve to underestimate the net benefit of a
college education since the incidence of unemployment is lower for college
graduates than it is for high school graduates. For women, however, especially
those who leave the labor force for a period of time to raise a family, the
full employment assumption will exaggerate the net return associated with a
college education. For each gender, the net benefit would be less if a person
retires before the age of 65. Given the assumption of a 44-year working life,
recent Census data suggest that the total lifetime earnings of a male worker
will be $1.27 million higher if he has a college degree than if he has only a
high school education. For women, the lifetime earnings differential is $0.96
million.
When
comparing streams of expenses and income that accrue over time, it is necessary
to “discount” figures to a common base year. The present discounted value of
receiving $10,000 ten years from now is less than $10,000 — not just because of
inflation, but because of the time value of money. If the annual real
(inflation-adjusted) rate of interest is 4 percent, then $10,000

to
be received 10 years from now has a present value of $6,756 in the sense that a
present period investment of $6,756 at a 4 percent interest rate would be worth
precisely $10,000 in 10 years.
If
expenses are discounted to the time an individual enters college (assumed to be
at age 18), then the total costs of attending college are $123,200 for men and
$110,700 for women. Discounting has a more dramatic effect on the value of
future earnings. The present values of the incremental earnings afforded by a
college education are $461,700 for men and $361,100 for women. On balance,
however, the benefits of a college education greatly outweigh the costs. When
evaluated at a discount rate of 4 percent, the net present value of a college
education is $338,500 for men and $250,400 for women.
To
compare the return on investment offered by a university education with other
investments, it is useful to compute the “internal rate of return.” This is the
discount rate that equalizes the present value of benefits and costs. The
concept of internal rate of return is equivalent to what financial economists
refer to as the “yield to maturity” on a financial asset. Returns calculated in
this way can be compared across all kinds of loans or bond purchases,
regardless of the time pattern of interest and principal payments. The internal
rate of return also can be thought of as a hurdle or break-even interest rate.
If the internal rate of return on a college education is 12 percent, this means
that a college participant could borrow at 12 percent interest all of the money
needed to pay for the costs of attending a four-year college and have just
enough in incremental college-generated earnings to pay off the loan with
interest.
For
men, the internal rate of return on a college education is 11.7 percent. For
women, the return (calculated assuming full lifetime employment) is almost
identical at 11.6 percent. Both of these represent returns over and above
inflation. These returns compare favorably with real returns on stocks that
have averaged around 7 percent over the past 100 years.
The
internal rate of return calculations conducted in this exercise include
estimates of public subsidies on the cost side (by estimating cost per year at
$15,000 when tuition averages only $5,000 per year at public research
institutions) and only private returns in the benefit calculations. In the
discussion in Chapter II, estimates of social benefits are included in the
calculations.
Distinguishing
the Effects of Educational Attainment from Ability
Social
scientists long have been concerned that simple correlations between
educational attainment and earnings may overstate the causal role played by
education in determining earnings capacity. Individuals with high innate
abilities, cognitive and non-cognitive, find it easier to be successful in
school and will complete more years of schooling. But these innate abilities
are themselves important in determining earnings capacity. Because abilities
are difficult to observe, the correlation between educational attainment and
unobserved ability will confound attempts to identify the true effect of
education on earnings.
One
method statisticians use to try to correct for unobserved and missing variables
is a technique known as “instrumental variables” (IV). In the case of earnings
and its relationship to educational attainment (observed) and ability
(unobserved), the idea is to find another variable (the instrument), that
determines and correlates with education but is itself uncorrelated with
ability. The true effect of education on earnings can be estimated by replacing
observed education with the value for education predicted by the instrument in
an earnings regression.
IV
studies of the return to education have used as instruments college tuition,
distance to college, and birth quarter (because of compulsory schooling laws,
people born with birth dates earlier in the year have slightly less years of
schooling than those born later in the year). The
18
consistent
and surprising finding of these studies is that IV estimates of the gross
return to schooling (the marginal impact of years of education on earnings) are
20-to-40 percent higher than simple estimates uncorrected for ability (Card
1999, 2001).
One
popular explanation for these results is that ability bias is small and that
the benefits of schooling among low-income disadvantaged subgroups (those most
likely to change their schooling status because of the instruments) must be
higher than the returns in the general population. There is some debate,
however, over how to interpret the findings. Carniero and Heckman (2002), for
example, have argued that the instruments commonly used in IV studies are
invalid since they likely are correlated with ability. Further, it does not
follow from the fact that IV estimates are higher than simple estimates that
disadvantaged groups have a higher return to schooling.
Some
studies of the benefits of schooling have tried to deal with the issue of
ability bias by using special data sets. Studies of identical twins, for
example, find that the benefit of schooling is 10 percent lower than simple
estimates (Card 1999). If one believes that identical twins have identical
abilities, then these findings suggest only a small upward bias in simple
estimates of the effect of education on earnings. Another special data opportunity
arises when countries enact broad changes in compulsory schooling laws.
Britain, for example, in 1972 raised the age at which children could leave
school from 15 to 16. With the new law, about one quarter of the youth
population was forced to stay in school an extra year. Presumably there was no
difference in the distributions of innate ability between people born in
1955/1956 and those born a little later who were affected by the law. Yet those
born later, those with extra schooling, had significantly higher earnings later
in adulthood. Estimates from these data suggest an earnings benefit of at least
10 percent for the extra year of schooling (Card 2002).
In
summary, the issue of ability bias remains a formidable statistical problem for
education researchers. But the weight of evidence from dozens of studies and
the consensus view of social scientists is that the earnings differential
between people with different levels of educational attainment is primarily a
reflection of education itself, not differences in ability (Card 2002).
Barriers
to Educational Attainment
For
those who complete a four-year college program, the return on investment for
the time and money spent on college is very high, something on the order of
11-to-12 percent. Yet only one-quarter of the U.S. adult population (28 percent
of those 25-34 years old) has at least a bachelor’s degree. If an investment in
college is so worthwhile, why do so many people choose not to invest? There are
three possible answers:
(1)
Some people cannot afford college, either the out-of-pocket expenses, such as
tuition and books, or the opportunity cost of being out of the labor force
while in school. For these people, the costs of college participation are very
high.
(2)
Some people do not have the academic skills necessary to be successful in
college. For these people, the benefits from college participation are very
low.
(3)
Some people are unaware or unconvinced of the economic value of a college
education. This is especially true of individuals whose parents never went to
college.
This
section reviews the empirical evidence on the factors affecting college
enrollment and graduation.
19
College
Enrollment and Family Income
A
strong correlation exists between college enrollment and family income. Figure
I:4 shows trends in college participation by 18-to-24 year old males who have
completed high school. College enrollment has risen over the past two decades,
probably in response to the rise in earnings differentials between the less and
more highly educated. College enrollment rates rose first among higher-income
groups, beginning in the early 1980s. Enrollment rates began to increase in the
early 1990s among youth from low-income families. Graduation rates, as measured
by a bachelor’s degree, have not increased as much.
More
striking about Figure I:4, however, is the direct relationship between college
enrollment and current family income. College enrollment rates in the bottom
income quartile are 15 percentage points lower than they are in the third quartile
and 25 percentage points lower than they are in the top half of the income
distribution. A similar relationship between college enrollment and family
income is apparent in data from other countries. The relationship also holds
for other dimensions of college participation, including whether an individual
enrolls in a two-year or four-year college, whether college entry is delayed,
and whether an individual completes a two-year or four-year program.
A
common interpretation of the relationship in Figure I:4 is that college
enrollment decisions are heavily influenced by the financial resources
available to the family. College is a good long-term investment for most
people. But children from low-income families are credit-constrained. They
choose not to enroll in college because they cannot afford either the
out-of-pocket expenses (such as tuition and fees) or the loss of income while
spending time in college.

Economists
note that loan markets for education are highly imperfect and may prevent
cash-constrained individuals from making good long-term investments.
Investments in human beings are unlike investments in physical assets. Students
cannot offer themselves as collateral. The lack of collateral and the
difficulty of monitoring performance make the market for human capital highly
imperfect. This argument, together with evidence such as that presented in
Figure I:4, is used to justify large-scale government programs to help finance
education (Carniero and Heckman 2002).
College
Enrollment and Academic Ability
Another
possible interpretation of Figure I:4 is that it reflects a more fundamental
relationship between college participation and the academic ability or college
preparedness of the student. Current family income is highly correlated with
long-run family income. Children who grew up in households that always had
ample financial resources are also likely to have been enrolled in high quality
primary and secondary schools. They are also more likely to have developed the
non-cognitive skills necessary to be successful in college.
Most
data sets that provide information on educational attainment and family income
do not contain measures of academic ability. One that does is the National
Longitudinal Survey of Youth (NLSY) which contains results from the Armed
Forces Qualification Test (AFQT), a measure of scholastic ability.
Cameron
and Heckman (2001) use data from the 1979-91 waves of the NLSY to separate out
the effects of family income from scholastic ability in explaining gaps in
college enrollment between minority youth and whites. They find that when they
do not control for ability in college attendance rates, 5 of the 11 point gap
between blacks and whites, and 4 of the 7 point difference between Hispanics
and whites, is explained by family income. When scholastic ability (as measured
by AFQT scores measured before high school graduation) is accounted for,
however, family income plays no role in explaining college attendance
decisions, although it does continue to affect high school completion rates.
Only one half of one point of the 11 point black-white gap is explained by
family income. For Hispanics, the gap actually widens when family income is
considered. Overall, it is ability and not current financial resources that
seems to account for the gaps between minority and white schooling attainment.
While
academic ability may be a more important determinant of college entry, family
income still may operate as an additional constraint. Adjusting for ability
weakens but does not eliminate the statistical relationship between income and
college participation. Figure I:5 shows data on college enrollment among white
males broken out by both family income quartiles and AFQT test terciles. The
data were prepared by Carniero and Heckman (2002) using a sample of white males
from the NLSY for 1979. The data suggest that even after controlling for
scholastic ability, adolescents from high-income families enroll in college at
higher rates than youths from low-income families.
College
Enrollment and Family Background
The
relationship between family income and college enrollment is likely to be
overstated not only because of the connection between income and scholastic
ability but also because of a correlation between income and family background
characteristics that are important for college participation. Children from
low-income families are more likely to have parents who are not themselves
college educated. Young adults who are 18-to-24 years old may be able to drive,
drink or vote, but they often lack the wisdom, discipline and foresight to make
good long-term 21

decisions.
Those who attend college often do so because of the values and expectations
instilled in them by their parents.
In
their study of college enrollment, Carniero and Heckman (2002) are able to
control not only for ability but also for family background variables such as
the educational attainment of the father and mother, whether the child is from
a broken home, and place of residence. The most statistically significant of
these variables are the parents' education status. The results of their
analysis are summarized in Figure I:6. Controlling for family background
weakens further the relationship between family income and college enrollment.
Comparing the highest and lowest income quartiles, there is only 4 percentage
point gap in college enrollment in the group with the highest ability and a 12
point gap in the lowest ability group.
Carniero
and Heckman also look at other dimensions of college participation. After
adjusting for both ability and family background, they find no meaningful or
significant remaining effect of family income on whether an individual
completes a four-year college program. Weak evidence exists of a relationship between
income and delay of entry into college. Overall Carniero and Heckman conclude
that at most 8 percent of American youth are subject to short-run liquidity
constraints that affect their post-secondary schooling. The present lack of
liquidity-constrained individuals in the population is undoubtedly due in large
part to government programs that help to ease financing burdens.
Thus,
the simple correlation between college participation and current family income
greatly overstates the causal role played by family financial resources in
college entry decisions. What seem to be more important for college educational
attainment are (1) the academic ability of the individual, which is shaped
throughout his/her life by a variety of family and
22

SOCIETAL BENEFITS OF ENHANCED EDUCATIONAL ATTAINMENT
Summary
•
Societal
benefits of a workforce with greater educational attainment and skills can be
traced to the enhanced worker productivity associated with greater educational
attainment. These productivity gains translate into higher output and incomes
for the economy.
•
Non-monetary
societal benefits in regions with high proportions of college graduates include
lower crime rates, greater and more informed civic participation, and improved
performance across a host of socioeconomic measures.
•
Intergenerational
social benefits may be very large as degree attainment today translates into
higher probabilities of degree attainment in future generations.
•
Empirical
work in econometrics suggests that after controlling for differences in
amenities and individual wages, a 1 percentage point increase in the share of
college graduates in the labor force leads to significant increases in wages
for all workers.
•
A
portion of this significant wage effect is attributable to spillovers that
result from productivity gains. Simulations for Arizona based on conservative
estimates of these spillovers suggest that combining social spillovers and
individual benefits realized from a four-year college degree, degreed workers
earn and are responsible for gross lifetime earnings that total $1.6 to $1.9
million more than workers with only a high school diploma.
•
Accounting
for costs of education and the time value of money, discounted lifetime net
benefits from a university degree — including combined individual and societal
benefits — exceed $600,000 per worker: a combined internal rate of return of
about 16 percent.
•
An
statewide simulation designed to measure the impact of raising the share of
college graduates in the labor force by 0.2 percent (the median annual rate of
increase observed in the econometric studies) that used Arizona data on
educational costs and wages reveals that total costs match benefits after about
11 years. After accounting for the time value of money, the payback period is
about 13 years and the net discounted benefits (benefits less costs) that
accrue after 20 years are estimated at $364 million.
•
Numerous
estimates of the rate of return to investments in education prevail in the
literature. Results suggest that significant portions of economic and job
growth are attributable to human capital while discernible evidence of
non-monetary benefits also is seen empirically.
Introduction
Investments
in physical capital, such as machinery, generally lead to higher worker
productivity, greater output, and enhanced economic prosperity. Economists also
have noted that significant benefits result from investments in human capital.
Acquiring a university degree is a form of human capital investment; the
benefits to the individual of acquiring a college education are large, as
discussed in Chapter I.
Broader
economic and societal benefits (also known as “social returns”) also result
from enhanced educational attainment. Social returns accrue from “spillovers” —
the benefits that extend to third parties other than students and institutions
of higher education. The greater labor productivity that educated workers bring
to the labor force is the source of these spillovers. In addition to monetary
benefits, a long list of non-monetary societal benefits from enhanced
educational attainment has been documented.
Simulations
based on the demographics of Arizona, the social cost of producing college
graduates, and recent estimates of social returns (taken from the academic
literature) indicate that
24
monetary
societal benefits potentially are very large. Non-monetary societal benefits
are extensive but not easily quantified. The significant benefits that
accumulate across generations are virtually impossible to quantify in a finite sample.
Evidence
of Societal Benefits
The
benefits to society from investments in higher education may be separated into
two types: monetary and non-monetary. Monetary social returns result from the
addition of more educated workers to the labor force, specifically by
increasing the labor force share of college graduates. The rationale for
monetary social returns follows:
•
Technological
Spillovers:
Social interaction is a catalyst for learning and overall knowledge creation.
The more contact that takes place among educated people, the more the stock of
knowledge expands. Learning and networking are important determinants of
knowledge creation. According to Lucas (1988), productivity spillovers are
large enough to explain the differences between rich and poor countries.
•
Human
and Physical Capital Complementarities: Physical and human capital can be
complementary. Increased education, knowledge, and skills create an increase in
the quality of the existing physical capital stock — increasing the
productivity of capital that translates in higher labor productivity for all
workers. For example, more educated workers use more sophisticated equipment
that results in improved productivity. Moretti (2004) provides empirical
evidence of this productivity enhancement.
•
Increasing
Returns: Romer
(1988) argues that there are increasing benefits to investments in human
capital. As the knowledge economy increases in importance, the role of human
capital may outstrip physical capital and labor in determining aggregate growth
rates across countries. Using this argument, the acquisition of knowledge
capital creates “endogenous” growth — growth that feeds on itself — and
economic returns that accelerate.
A
portion of the societal benefits generated in this fashion are attributable to
spillovers that provide a basis for public investment in endeavors that
increase the number of college graduates in the workforce.
Monetary
benefits may be large for subsequent generations. Thus, capturing total returns
to the investment in education may not be a matter of just discounting a future
stream of income over a single lifetime.
Spillovers
from college-educated workers result in non-monetary societal benefits that
have been widely documented:
•
Reduced
crime rates:
Crime statistics suggest that higher educational attainment is associated with
a lower incidence of crime. As illustrated in Chapter I, greater educational
attainment results in substantial monetary benefits to an individual, which
increases the cost of incarceration in terms of foregone earnings. To the
non-economist, this argument is based on the notion that individuals with low
educational attainment and skills risk little financially by resorting to
crime.
•
Civic
participation: Social
and behavioral statistics suggest that higher educational attainment is
associated with greater civic participation, ranging from work with local civic
groups to greater voter participation. Milton Friedman, a conservative
economist, believed that public support for the laissez-faire approach to economic
market mechanisms could be achieved by increasing knowledge: more educated
individuals are less influenced by populist rhetoric and make more rational,
informed decisions in voting behavior.
25
•
Other
socioeconomic benefits: Additional years of educational attainment are
associated with a number of other benefits. The following list taken from Wolfe
and Haveman (2002) does not exclusively pertain to college graduates:
o
Non-wage
labor market remuneration, such as fringe benefits, and the quality of working
conditions are positively affected by educational attainment levels.
o
Consumer
choices are more rational and efficient.
o
Job
searches are more extensive among the more highly educated, resulting in a
better match between the individual and the company, which enhances efficiency.
o
Savings
rates are higher among the more highly educated.
o
Research
and development activities are more common and numerous in regions with higher
educational attainment.
o
Less
dependence on transfer payments and the social safety net occur among the more
highly educated.
o
Less
criminal behavior and lower incarceration rates occur among the more highly
educated.
o
Charitable
giving increases with educational attainment.
o
Social
cohesion is higher among the more highly educated, as reflected in higher
voting rates.
o
The
educational attainment and cognitive development of children are positively
affected by the educational attainment of parents (first-generation effects).
o
The
health of the individual, their spouse, and their children are positively
related to educational attainment.
o
Desired
family size is more commonly attained among those with higher educational
attainment.
Quantifying
Societal Benefits
While
widely discussed, relatively few authors have attempted to quantify the social
benefits of higher education investments. One way to do so is to examine
whether regional economies with greater proportions of college trained workers
exhibit evidence of prosperity that may be attributed to the higher levels of education
attainment. Recent work by Enrico Moretti (2004a, 2004b) is a notable
exception. Moretti examines the relationship between greater labor force shares
of college graduates and the wages attained by all workers, as well as the
productivity of manufacturing enterprises.
The
challenge in quantifying the social benefits of higher education is to
establish statistical evidence of a causal relationship linking additional
education to observed outcomes. Otherwise, the relationship may be simply a
correlation of higher wage employment opportunities and greater numbers of
college graduates, or a relationship of both to unobservable attributes. The
following provides a technical perspective:
•
If
changes in the share of college graduates are positively related to
unobservable factors that influence labor supply, then simple ordinary least
squares (OLS) estimates (e.g. simple correlations) of the impact of college
graduates on wages would be biased downward, understating the extent
that college graduates actually contribute to wage determination. Essentially
the positive labor supply shocks dampen wages and obscure the positive impact
that graduates have on the labor market.
•
If
changes in the share of college graduates are positively related to
unobservable factors that influence labor demand, then simple OLS estimates of
the impact of college graduates on
26
wages
would be biased upward, overstating the extent that college graduates
actually contribute to wage determination. Essentially the positive demand
shocks increase wages so the observed wage effect is the combination of the
demand shock and the effect of increased graduates in the area.
•
Moretti
(2004a, 2004b) controls for a host of factors that explain wage and
productivity differentials across cities and through time, uses instrumental
variable techniques to account for potential reverse causation, and checks
results against a distinct longitudinal data set. These approaches are designed
to establish evidence, or lack thereof, of a causal relationship.
Moretti’s
estimates of the effect of college graduates on wages employs census data for
1970, 1980 and 1990 from 282 cities using nearly 2 million observations. The
results are checked against a sample of 6,791 individuals in a national
longitudinal sample spanning 201 cities from 1979 to 1994. Results are
remarkably consistent across the two distinct samples and yield estimates of
the social benefit of attracting greater numbers of college graduates to a
city. Moretti finds, after controlling for other factors, that a 1 percent
increase in the labor force share of college graduates in a city drives up
wages for all workers:
•
1.9
percent for labor force participants without a high school diploma
•
1.6
percent for labor force participants with a high school diploma
•
0.4
percent for college graduates.
Moretti
argues that the observed wage benefits are a combination of spillovers,
complementarities and substitution effects that are induced by changes in the
labor force composition that take place as a natural consequence of labor
market adjustments triggered by the change in the supply of educated workers.
Together, these effects are large. Moretti estimates that for cities
experiencing an increase in the share of university graduates of about 0.2
percent per year (the median in the sample) and an average salary of $25,000
(in this historical sample), the additional graduates in the labor force
induced wage increments of $95.00 per high school dropout, $80.00 per high
school graduate, and $20.00 per college graduate.
All
of these wage effects cannot be attributed to spillovers generated by the
additional graduates because other labor market effects also exist. However,
estimates of the net wage effect on college graduate wages alone help establish
a lower bound for the spillover effect. The wage increment represents the net
effect of the social spillovers and the wage-dampening supply shock induced by
the greater number of college graduates. If the additional supply of graduates
has a greater impact on wages than does the social spillover, the net impact on
wages of college graduates would be negative. Instead, Moretti’s estimates
suggest a net positive increment to wages of 0.4 percent. Assuming that the
supply shock has zero effect (unlikely but arithmetically conceivable), a lower
bound for the social spillover effect for college graduates is obtained at 0.4
percent though the actual spillover effect is likely to be larger. For purposes
of discussion in the examples that follow, the social spillover is assumed to be
only 0.4 percent for all workers. That is, the examples will presume that the
social spillover accounts for only about 25 percent (0.4 percent of the 1.6
percent) wage increment for high school degree holders and just over 20 percent
(0.4 percent of the 1.9 percent) for high school dropouts. Thus, the examples
adopt a very conservative estimate of the portion of these estimates that
pertain to spillovers.
A
Simulation Based on Moretti Estimates
Moretti’s
estimates apply on average to hundreds of cities and nearly 2 million workers
across the better part of three decades. For illustration purposes, it is
useful to examine the
27
impact
of wage inducements of this order of magnitude on the labor force (25-to-64
years of age) of the Arizona economy.
While
Moretti’s work focused on cities, the simulation in this section applies to the
entire state. Since the dominant share of economic activity in Arizona takes
place in the metropolitan areas, this need not skew results. The simulation
contains several distinct steps:
1.
Estimate the percentage of the workforce with particular educational attainment
levels as well as estimate earnings attained by these individuals using numbers
from the decennial census.
•
High
School Dropout
•
High
School Diploma
•
College
Graduate or Higher
2.
Determine the number of college educated people that must be added to the labor
force to change the proportion of college graduates by 0.2 percentage point,
the median annual increase in Moretti’s sample.
3.
Estimate the social cost of locally educating college graduates by examining
the cost of taking a new college entrant to graduation. The simulation accounts
for natural attrition rates and the observation that not all locally educated
students remain in the state upon graduation.
4.
Compare the costs of locally educating and graduating university students with
the benefits that accrue to higher labor-force wages using a life-cycle
scenario that tracks when costs are borne and when benefits accrue. Assessment
of benefits adopt the conservative 0.4 percent estimated wage increment for all
workers so the results are consistent with establishing a lower bound for the
impact of social benefits that accrue to greater numbers of college graduates
in the labor force.
The
data used as the foundation for the simulation are in Table II:1. Using
estimates from the decennial census and disaggregating labor force participants
by both age and educational attainment provides more precise estimates of the
wage effects. An increase in the labor-force share of graduates in the 2000
sample yields estimates of an annual wage increase of $183 million. The lower
bound for the social spillover benefits (applying 0.4 percent to all workers)
yields an aggregate wage increment of about $64 million.
In
2000, nearly 2 million labor force participants between the ages of 25 and 64
were reported by the census in Arizona. An increase of 4,000 graduates to the
labor force would increase the college share by about 0.2 percent. Hence, the
social spillover per additional graduate is $16,000 ($64 million divided by
4,000) using the lower bound estimates.
The
social contribution per graduate can be added to the benefits to the individual
estimated in Chapter I to obtain a combined social plus private internal rate
of return. Rather than using Arizona-specific costs of attending college, the
cost estimates used in the simulation are the same as those applied in Chapter
I in the analysis of private returns. The full costs of going to college
include tuition and fees paid by the student, state and local government
appropriations in the case of a public university, and foregone earnings during
the time the student is attending college. For public four-year research
institutions, average tuition and fees are approximately $5,000 per year and
government appropriations are around $9,000 per full-time equivalent student
per year. For private four-year research institutions, mean tuition and fees
are about $16,000 per year. In this analysis, a figure of $15,000 is used to
represent the annual direct cost of attending college as an average of the
costs of public and private institutions. Over four years, the total direct
costs would be $60,000. Assuming that college students work only during the
28
summer
and earn what a high school graduate would make, the earnings foregone by a
male when attending college are $17,650 per year, or $70,600 over four years.

Benefit
calculations are made assuming the individual is fully employed from age 22 to
65. For men, this assumption may serve to underestimate the net benefit of a
college education since the incidence of unemployment is lower for college
graduates than it is for high school graduates. For women, however, especially
those who leave the labor force for a period of time to raise a family, the
full employment assumption exaggerates the net return associated with a college
education. Given the assumption of a 44-year working life, recent Census data
suggest that the total lifetime earnings of a male worker will be $1.27 million
higher if he has a college degree than if he has only a high school education.
For women, the lifetime earnings differential is $0.96 million. An increment of
$16,000 per year for ages 25 and older is added to account for the lower bound
of social spillovers. Hence the benefit stream contains the private benefits
that accrue to the individual plus the social benefits that the employment of
the individual generates for the rest of the economy.
As
in Chapter I when comparing streams of expenses and income that accrue over
time, it is necessary to “discount” figures to a common base year. The present
value of receiving $10,000 ten years from now is less than $10,000—not just
because of inflation, but because of the time value of money. If the annual
real rate of interest is 4 percent, then $10,000 to be received 10 years from
now has a present value of $6,756 in the sense that a present period investment
of $6,756 at a 4 percent interest rate would be worth precisely $10,000 in 10
years.
Again,
as in Chapter I, if expenses are discounted to the time an individual enters
college (assumed to be at age 18), the total costs of attending college are
$123,200 for men and $110,700 for women. However, additional social benefits of
$640,000 accrue to society over the lifetime of each worker. Including these
social benefits and assuming a discount rate of 4 percent, the net present
value of a college education is $591,277 for men and $503,193 for women, as
seen in Table II:2.

To
compare the return on investment offered by a university education with other
investments, it is useful to compute the internal rate of return that now
combines social costs and benefits with private costs and benefits. This is the
discount rate that equalizes the present value of all benefits and costs. For
men, the internal rate of return on a college education is 15.7 percent. For
women, the return (calculated assuming full lifetime employment) is similar at
16.6 percent. Both of these represent returns over and above inflation. These
returns compare very favorably with real returns on stocks that have averaged
around 7 percent over the past 40 years.
An
Aggregate Simulation
The
aggregate net benefit from an enhancement of educational attainment in Arizona
is estimated using data on the Arizona labor force. In this simulation, an
increase in the labor force share of university graduates is targeted at 0.2
percent and only social costs and benefits are included. In 2005, this would
require an addition of about 4,500 graduates. A plan to add 0.2 percent by the
time 18-year-old students in 2005 reach the age of 25 would require about 5,500
graduates assuming current trend growth of the Arizona labor force. The social
cost (government appropriations) to produce 5,500 graduates who will work in
the Arizona labor force is estimated at about $440 million assuming current per
student funding levels, normal attrition rates in college attendance, a normal
pattern of migration of university graduates to other states, and the
possibility that many students will take five years to graduate. Programs that
accelerate graduation rates could reduce the costs.
Since
there is natural growth in the Arizona labor force, ongoing costs estimated at
7 percent of this total per year would be incurred to maintain the labor force
share of graduates at 0.2 percent greater for all time periods. After 10 years
the total cost of producing these degrees is estimated at $615 million and
after 20 years the total cost increases to $1,210 million. Costs are assumed to
increase by 7 percent per year in nominal terms. It would be possible to reduce
costs, by instituting scholarship plans that provide incentives to complete
degrees in a more timely fashion and to seek employment within the state of
Arizona upon completion of degree.
Social
benefits are obtained by using estimates of the lower bound for the social
spillovers, which in 2005 are estimated at $88.7 million. But benefits do not
accrue until the graduates reach the age of 25 in this scenario and at that
point the wage increment swells in nominal terms to $152.5 million, growing at
a rate of 7 percent per year thereafter, estimated from the nominal impact of
inflation plus growth in the Arizona labor force at current trends. Comparing
aggregate social benefits and costs in this simulation reveals that the nominal
benefit and cost streams are equal after about 11 years following the
implementation of the plan. Accounting for both nominal and real effects and by
discounting each stream at 7 percent extends the payback period to 14 years
since the costs are largely incurred prior to realizing the benefits. However,
after 20 years, discounted social benefits exceed discounted social costs by
$364 million.
A
number of alternative simulations are conceivable. In the example above, it is
assumed that only a 0.2 percent increase in the labor force share of graduates
is targeted. Programs that continually increase the labor force share could be
adopted, and private costs and benefits could be added. Because of the large
internal rates of return that accrue to investment in higher education, results
similar to those in the simple simulation discussed in the prior subsection are
likely to prevail. Decreases in ability to retain graduates in the state will
reduce net benefits while programs that lead to in migration of college graduates
will lead to increases in net benefits.
31
Social
Returns Simulation: Caveats and Qualifications
•
The
simulation applies estimates obtained from the 2000 census to labor force
participants between the ages of 25 and 64 across the state, whereas Moretti’s
estimates were obtained from a historical sample of cities. The simulation is
supply driven in the sense that it measures the impact of increasing the supply
of college graduates on the economy. It presumes that there will be sufficient
demand for the knowledge and skills that these workers possess.
•
The
simulation does not account for the opportunity cost of social investments (the
use of public monies for other purposes). The direct economic benefits that
would accrue due to the additional expenditures on the production of additional
local graduates also are not included. In addition, the social and private
returns that accrue to those who do not complete their college education are
not estimated but the social costs of students who do not graduate are included
in the analysis. Finally, the simulation employs “lower bound” estimates for
the spillover effect.
•
The
simulation assumes an increased number of university graduates from local
institutions of higher education. Even greater economic impact could be
obtained if a region could become a “magnet” for educated workers — attracting
them from outside the region to work locally. In this case the region reaps the
benefits of the educated workers without bearing all the costs. However,
greater local production of university graduates may assist in inducing this
“magnet” effect.
•
Local
production of university graduates invariably entails adding degreed students
at the low end of the age and experience profile.
•
Additional
cost reduction could occur if student retention rates increase, if the social
subsidy per student is reduced, or if greater numbers of locally produced
students remain in the state.
•
The
aggregate simulation does not address economic activity that occurs from age 16
to 24. College students and recent graduates (ages 22 to 24) earn income. The
opportunity cost of not attending college is the income forgone while attending
college. The net effect of these factors is not measured in the analysis.
•
The
estimates obtained in Moretti’s analysis reflect the combination of greater
productivity produced by higher levels of human capital. Education combined
with quality employment opportunities results in higher remuneration for
workers. This process may take time to evolve.
•
Moretti
effects prevail on average across hundreds of cities. The effect on any single
region or state can vary.
•
Despite
Moretti’s best attempts to identify a causal relationship, it remains possible
that higher educated workers are simply attracted by quality job opportunities
and migrate accordingly. Regardless, the availability of quality job
opportunities will be necessary for these effects to take place. And the
empirical evidence suggests that an educated workforce is an inducement for
attracting and retaining these quality job opportunities.
Additional
Work on Social Benefits
The
empirical analysis of the size of monetary social benefits induced by higher
education will continue as economists learn more about the spillover effects of
investments in human capital. The estimates used in the social benefit
simulations are designed to illustrate the types of social returns that accrue
due to the addition of more graduates into the labor force. The
32
impact
is substantial despite the use of estimates at the lower bound of the range of
possible effects of the social benefit.
Additional
literature suggests that there are many avenues that the production of college
degrees can take in influencing economic activity. Using growth accounting
techniques, King and Smith (1988) estimated that only 1.9 percent of annual
economic growth rates from 1940 to 1980 was non-education related. Pencavel
(1991) estimates that from 1913 to 1950 only 1.3 percent of total growth was
directly attributable to higher education, but higher education accounted for
14.6 percent of the growth from 1973 to 1984. Aschauer (1994) estimates that
15-to-to-20 percent of economic growth observed in the U.S. is attributable to
the accumulation of education capital. Howe (1994) examines the incidence of
unemployment across individuals with different levels of educational
attainment, finding that the lowest incidence of unemployment occurred in
worker populations that had college degrees. Hoenick (1994) argues that
attainment of advanced degrees increases the likelihood that workers can adapt
to technological change — as in Shumpeter’s notion of creative destruction —
and thus are important in building a labor force that can better withstand the
pace of technological change.
Glaeser
et al. (2000, 2003) examines wages in cities — identifying effects that accrue
to those cities with higher education and skill levels. Results point to
agglomeration spillovers that manifest themselves in faster growth and higher
wages as educated people interact. Gottlieb and Fogarty (2003), using similar
data, confirm the result and note that it persists across a wide range of
cities even after controlling for region. Jorgensen (2000) et al. estimates
that a considerable portion of the late 1990s growth was directly attributable
to roles played by research innovation at institutions of higher education and
the greater absorptive capacity of a labor force with greater proportions of
college graduates. Wang (2003), in an extensive study of the impact of
universities on surrounding cities, finds that proximity to institutions of
higher learning induce greater rates of job growth.
As
difficult as the social monetary benefits are to quantify, the implicit value
of non-monetary benefits are even less conducive to measurement. However, the
non-monetary contributions that more educated individuals bring to society,
coupled with the reduction in social costs that they incur over their
lifetimes, suggests that the non-monetary benefits represent considerable
return on social investments made to support higher education.
Perhaps
most important are the intergenerational effects that accrue to investments in
higher education. The quantitative importance of these effects is very
difficult to estimate precisely since costs to society incurred today to create
opportunities for individuals to acquire college degrees must be compared to
benefits realized two, three or four generations in the future.

EMPIRICAL DATA ON HIGHER EDUCATION
ENROLLMENT
AND FINANCE
Summary
•
Enrollment
in degree-granting institutions of higher education in Arizona as a percentage
of the state’s population was about equal to the national average in 2003. The
Arizona figure was higher than the national average at private for-profit
institutions, slightly greater than the national average at public
institutions, but considerably below average at private not-for-profit
institutions.
•
Combining
both public and private institutions, total revenues and expenditures per
student at Arizona institutions of higher education were far below the national
averages in 2003, among the least in the nation. Among public institutions,
Arizona’s per student higher education revenues and expenditures were not as
far below average, but still ranked among the bottom 10 states in the nation.
•
The
ability to pay in Arizona is below average due to the state’s subpar incomes.
Thus, the state’s higher education revenues and expenditures per student
adjusted for income were not as far below the national averages in 2003. Among
public institutions, Arizona’s per student revenues and expenditures were close
to the national average, ranking near the middle of the states.
•
Public
financial support for higher education, as measured by government
appropriations, was marginally higher in Arizona than the national per student
average in 2003, with Arizona ranking just above the middle of the states.
However, tuition and fees and other revenues were far below the per student
average.
•
Adjusted
by the state’s ability to pay, public support for higher education in Arizona
was considerably higher in 2003 than the national average.
•
Increases
in public support for higher education per student have been nearly equal in
Arizona and the nation. However, the increases have not been as great as gains
in the ability to pay, particularly in Arizona.
Introduction
Higher
education is defined to include all public and private degree-granting
institutions, which primarily consist of two-year colleges and
four-or-more-year (hereafter referred to as four-year) universities. The National
Center for Education Statistics (NCES) is the primary source of statistics on
higher education. The NCES provides various measures of higher education
enrollment and finance annually, but their latest complete data by state are
for 2001 (the 2000-01 fiscal year). Incomplete data are available for 2003.
Education
finance and enrollment data are adjusted by other data — population, gross
product, and personal income — that are produced by the U.S. Department of
Commerce. Data for Arizona are compared to the national average, all states
(including the District of Columbia), and two smaller groups of states: 10
competitor states (California, Colorado, Florida, Georgia, Nevada, New Mexico,
Oregon, Texas, Utah, and Washington) designated by the Greater Phoenix Chamber
of Commerce, and 10 new economy states (California, Colorado, Connecticut,
Maryland, Massachusetts, Minnesota, New Jersey, Utah, Virginia, and Washington)
selected by the Milken Institute.

For
more detail on higher education enrollment and finance than presented in this
chapter, see the report “Higher Education Enrollment and Finance in Arizona
Compared to All States” available at (www.wpcarey.asu.edu/seid/Reports.cfm).
All
Institutions
The
NCES database for 2003 includes 76 degree-granting institutions of higher
education in Arizona. Of these, all enrollment and financial data were missing
from three and financial data were missing from eight others. Thirty-four of
the 76 were private for-profit institutions, with the share of both two-year and
four-year institutions above the national average. In contrast, the 17 private
not-for-profit institutions accounted for a below-average share of the total.
The five public four-year universities (the three campuses of Arizona State
University plus Northern Arizona University and the University of Arizona) also
made up an unusually low share of the total.
The
significance of missing data varies widely by state, with data for some major
institutions in other states missing from the NCES 2003 database. Thus, the
incompleteness of the data needs to be considered in evaluating the information
presented in this section. The financial data are for fiscal year 2003.
Enrollment figures are on a full-time-equivalent (FTE) basis for Fall 2003.
Total revenues and expenditures in Arizona in 2003 are compared to the national
average and to each of the comparison groups of states based on three
classifications of degree-granting institutions of higher education: all
institutions, public and not-for-profit institutions (excluding for-profit
institutions), and public institutions only.
Enrollment
Enrollment
at public institutions in Arizona was nearly 196,000, split almost equally
among two-year colleges (99,000) and four-year universities (nearly 97,000).
Enrollment at public institutions accounted for 2.1 percent of the national
total, compared to the state’s population share of 1.9 percent. The share of
the nation was above average among two-year colleges at 2.7 percent but
slightly below average at four-year universities at 1.7 percent. All three of
Arizona’s original public universities had enrollment in excess of 15,000 and
ASU West had 5,000 students. Three public community colleges had enrollment of
more than 10,000 and three others exceeded 5,000.
In
contrast, enrollment at private not-for-profit schools in Arizona totaled just
10,700, only a tiny share of the national total at 0.2 percent for two-year
institutions and 0.4 percent for four-year schools. None of the private
not-for-profit institutions in Arizona are large. Grand Canyon University had
the greatest enrollment at 2,000.
The
enrollment of 104,000 at private for-profit schools in Arizona consisted
largely of the 71,000 students in the online campus of the University of
Phoenix that the NCES includes in the Arizona statistics. However, even after
excluding these students, for-profit institutions in Arizona still made up a
large share of the national enrollment total: 5.4 percent of two-year schools
and 5.3 percent of four-year schools. The University of Phoenix was the only
for-profit institution with enrollment of more than 2,500, with nearly 8,000 at
their Phoenix campus and a little more than 3,000 at their Tucson campus.
Excluding the online campus, total private school enrollment in Arizona made up
only 1.3 percent of the national total.
Accounting
for 23 percent of the state’s enrollment total, the online campus at the
University of Phoenix greatly influences the Arizona enrollment and finance
data. It was not excluded from the following analyses because of similar
institutions being included in other
35
states.
Instead, given this anomaly, the specialized nature of many degree-granting
for-profit institutions — such as the Arizona Automotive Institute, the
Refrigeration School, and the Scottsdale Culinary Institute — and extremely
high per-student revenue and expenditure figures at some for-profit
institutions, some of the following analyses exclude for-profit schools.
Total
enrollment in Arizona was 311,000. As a percentage of the state’s population,
enrollment was 27 percent higher than the national average, ranking sixth in
the nation and second among both the competitor states and the new economy
states. However, excluding the for-profit institutions, enrollment totaled
206,000; enrollment as a percentage of the population was 12 percent below
average in Arizona, ranking near the bottom of the states: 43rd overall, eighth
among the 11 competitor states and ninth among the 11 new economy states.
Looking only at public institutions, Arizona’s enrollment as a percentage of
population was 9 percent above average, ranking in the middle of the states
among all comparison groups of states.
Enrollment
at public institutions as a share of enrollment at all institutions was below
average in Arizona, ranking 42nd overall, last among the competitor states, and
ninth among the new economy states. Excluding for-profit institutions, the
comparison reverses, with the public share in Arizona well above average,
ranking fifth overall, third among the competitor states, and first among the
new economy states.
Total
Revenues and Expenditures
Revenues
and expenditures are measured three ways: per FTE student, per FTE student
relative to per capita personal income (PCPI), and per FTE student relative to
per capita gross state product (PCGSP). The latter two measures reflect ability
to pay.
Based
on the classification including all institutions, revenues per student in
Arizona were 40 percent below the national average, ranking the state 48th
overall, 10th among the 11 competitor states, and last among the new economy
states. Excluding the for-profit institutions does not substantially change the
results, with Arizona 29 percent below the national average, the national rank
46th, and the rank among the two other comparison groups unchanged. Looking
only at public institutions, the shortfall is smaller at 15 percent, but the
national rank goes up only to 44th and the rank among the competitor states to
eighth; Arizona still ranks last among the new economy states.
The
comparisons of expenditures per student are similar to those of revenues per
student except for the classification of all institutions, in which Arizona
ranked last among all states at 50 percent below average (see Table III:1).
Thus, higher education revenues and expenditures per student are quite low in
Arizona regardless of the set of higher education institutions included.
Per
capita personal income and per person gross product in Arizona are considerably
below the national averages, according to data reported by the U.S. Department
of Commerce’s Bureau of Economic Analysis. (The 2000 census, however, indicated
that per capita income in Arizona was not so far below average.) Thus,
comparing revenues and expenditures per student to PCPI and PCGSP somewhat
raises Arizona’s higher education rankings and ratio to the national average.
However, among all institutions and the classification excluding for-profit
schools, the state still was far below the national average. Among public
institutions, Arizona’s per student revenues and expenditures were close to the
national average, ranking near the middle of the states.

Categories
of Revenues and Expenditures
The
NCES divides revenues into three categories: tuition and fees, state and local
government appropriations, and other. Since appropriations are made only to
public institutions, they are analyzed in the following section. Expenditures
are split into five categories: instructional support, academic support,
student services, institutional support, and other.
Tuition
and fees per student in Arizona were considerably below the national average in
2003 in each of the three classifications of institutions, though Arizona’s
ranking was above the middle of the states in the all institutions
classification. Among public institutions, per-student tuition and fees were 15
percent below average, ranking 36th overall, fifth among the competitor states
and 10th among the new economy states. Arizona still was a little below average
after considering ability to pay.
Arizona
was far below average in the category of “other” revenues, ranking last among
the states among all institutions and in the classification excluding
for-profit institutions, and 47th among public institutions. Even after
considering ability to pay, Arizona’s public-sector figure was 20 percent below
average, ranking among the bottom 10 states overall and third to last among the
competitor and new economy states.
Arizona
was far below average on expenditures per student in each of the five expense
categories, ranking at the bottom of the states among all institutions and near
the bottom in the classification excluding for-profit institutions. Among
public institutions, Arizona’s figure ranged from 7 percent below average in
the academic support category (ranking 26th) to 30 percent below average in the
student services category (ranking 45th).
37
Public
Institutions
This
section focuses on public support for higher education, defined as state and
local government appropriations for higher education expressed on a
full-time-equivalent student basis. While appropriations are only a portion of
the total funding available to public institutions of higher education, the
other sources (such as tuition and fees) do not represent public support.
Traditionally,
public support for higher education has been defined as state government
appropriations; for example, the Grapevine project of Illinois State University
has collected state government appropriations for higher education since 1961.
The focus on state government, however, fails to recognize that in some states
local governments contribute substantially to the funding of higher education
while in other states all of the funding comes from the state government. The
State Higher Education Finance project (SHEF) of the State Higher Education
Executive Officers organization (SHEEO) reports that local government’s share
of total appropriations in 2004 averaged 10 percent nationally, but was 35
percent in Arizona — the highest proportion in the nation. (Wisconsin ranked
second at 23 percent.) Thus, looking only at state government appropriations
results in a misleading evaluation of government support for higher education
across the states.
The
Grapevine data on state government appropriations for higher education is
timelier than the NCES data. In 2004, Illinois State University for the first
time included local government appropriations (collected by SHEF). However,
since enrollment data are not available for 2004, the Grapevine project
compares appropriations data by state on a per capita basis. By not reflecting
the state-to-state fluctuations in public institution enrollment as a
percentage of the number of residents, per capita appropriation measures
produce an incomplete picture of public support. Similarly, state and local
government appropriations for higher education as a share of total government
spending or of tax revenues also present an incomplete picture since
enrollments are not considered.
Through
2001
Complete
annual data through 2001 are available from the NCES; data for 2001 are
compared especially to those of 1991, a comparable year in the economic cycle.
Nationally, the percentage of the population enrolled in public institutions of
higher education held nearly steady near 3 percent between the mid-1980s and
2001. The Arizona percentage was higher than the national average in each year,
but the differential declined from a little more than 1 percentage point
between the mid-1980s and early 1990s to 0.4 in 2000 and 2001 (see Figure
III:1).
The
main reason for Arizona’s higher-than-average percentage of the population
enrolled in public institutions of higher education is the relative shortage of
private not-for-profit institutions of higher education in Arizona. The readily
available and affordable nature of the community college system in Arizona is
another reason.
State
and local government appropriations for higher education per
full-time-equivalent public student averaged $7,159 nationally in 2001
according to the NCES. The Arizona figure of $6,711 was 6.3 percent less. In
1991, the Arizona figure was 4.8 percent less than the national average.
Arizona’s figure fluctuated from 1 to 8 percent less than the national average
between 1991 and 2001 (see Figure III:2). The differential typically was
somewhat larger during the 1980s. State and local government higher education
appropriations per FTE student in 2001 in Arizona ranked 30th among all states
and the District of Columbia according to the NCES data. In 1991, Arizona had
ranked 29th.

This
measure of appropriations per FTE student does not consider Arizona’s lesser
ability to pay. State and local government appropriations as a percentage of
gross product was higher in Arizona (0.74 percent) than the national average
(0.61 percent) in 2001. The 2001 percentages were less than those in 1991,
especially in Arizona, as seen in Figure III:3. However, this measure of
appropriations as a percentage of gross product does not reflect Arizona’s
above-average proportion of residents enrolled in public institutions of higher
education.
Appropriations
by state and local governments for higher education rose an inflation-adjusted
30 percent nationally between 1991 and 2001. Arizona’s real increase was a
little larger at 35 percent, but both the national and Arizona increases were less
than real economic growth. Nationally, real gross product gained 41 percent
during the decade, while in Arizona real GSP surged 95 percent.
On
a per FTE student basis, the 17 percent real increase in appropriations in
Arizona was slightly less than the national average of 18 percent. While
inflation-adjusted appropriations rose even on a per student basis, the
increase was less than the rate of economic growth, especially in Arizona. Per
capita real gross product rose 25 percent nationally and 39 percent in Arizona
between 1991 and 2001. Thus, whether measured in aggregate terms or on a per
person basis, appropriations for higher education did not keep up with economic
gains between 1991 and 2001, especially in Arizona.
In
order to incorporate both enrollments and ability to pay in one measure, state
and local government appropriations per FTE student were calculated as a share
of gross product per capita. As seen in Figure III:4, Arizona’s figure has been
greater than the national average, but the differential was less in 2001 than
over the prior decade. Thus, public support for higher
40
education
in Arizona has waned relative to the national average, but the state’s effort
remains higher than the national average because of its limited ability to pay.
In
2003
Arizona’s
total higher education appropriation per FTE student at public institutions was
3 percent higher than the national average in 2003, ranking just above the
middle of the states at 20th. Arizona ranked third among the competitor states
and fifth among the new economy states. Considering Arizona’s reduced ability
to pay, the figure was 20 percent above average relative to PCPI, ranking 14th,
and 18 percent above average relative to PCGSP, ranking 15th. On each
ability-to-pay measure, Arizona ranked second among both the competitor states
and new economy states.

EMPIRICAL DATA ON EDUCATIONAL ATTAINMENT
Summary
•
Arizona
ranks in the middle of the states on the percentage of its residents possessing
a bachelor’s degree, slightly below the U.S. average. However, educational
attainment has increased less in Arizona than the national average in recent
decades.
•
Arizona
compares less favorably among labor force participants, since the state’s
overall educational attainment is bolstered by highly educated retirees who
migrate to the state at retirement.
•
The
educational attainment of young adults in Arizona is substantially below the
national average.
•
Among
those educated in Arizona and among immigrants to the state, educational
attainment is relatively low. In contrast, the attainment of interstate
migrants is considerably higher.
Introduction
Two
basic trends impact educational attainment statistics. First, regardless of the
year in which a group was born, educational attainment rises rapidly until the
group reaches the age of the early-to-mid-20s, then advances much more
gradually. (For example, the average educational attainment of those born in
1965 was considerably higher in 1990 than 1980, but not much higher in 2000
than in 1990.) Second, average educational attainment climbed considerably with
the year born through the mid-20th century, then much more gradually. (For
example, the average educational attainment of those born in 1950 was much
higher than the average of those born in 1900, but the average attainment of
those born in 1970 was not much different than that of those born in 1950.)
The
only accurate statistics on educational attainment by state come from the
decennial censuses. Thus, this chapter reports data from 2000, with some
comparisons to earlier censuses. Of the many ways in which to measure
educational attainment, the percentage with a bachelor’s degree is used in this
chapter. Based on another measure, such as the proportion with a high school
diploma, the geographic pattern of educational attainment may be quite
different. For example, the correlation by state between high school graduates
and university graduates was only a moderate 0.43. For other measures and more
detail see the report Educational Attainment in Arizona Compared to All
States, which will be available in November 2005 at
(www.wpcarey.asu.edu/seid/Reports.cfm).
Educational
Attainment in Arizona Relative to All States
Educational
attainment statistics generally are expressed for the population 65 or older.
Most of the states with the highest educational achievement as measured by the
proportion with a bachelor’s degree were located along the Atlantic Coast, from
New Hampshire and Vermont south to Virginia. Colorado and Washington also were
among the top 10. Southern states had the lowest attainments, but were joined
by Nevada and Indiana. Arizona ranked tied for 25th, with a percentage slightly
below the national average. As seen in Table IV-1, a substantial variation by
state exists in the proportion with a bachelor’s degree.
Focusing
on the small proportion of the population who had earned at least a master’s or
professional degree (just 8.9 percent nationally), the leading states were
similar to the list for those with at least a bachelor’s degree. States in the
South, as well as several in the northern .Plains and northern Rocky Mountain
regions, had the lowest percentages of residents with a

graduate
degree. Arizona’s figure of 8.4 percent was a little less than the national
average but ranked tied for 20th.
Several
of the Plains and Great Lakes states that had among the higher attainments
based on high school diplomas or more education had among the lower attainments
based on the percentage with at least a bachelor’s degree. In contrast, several
northeastern states and California compared more favorably on university
graduates than on high school graduates.
Between
1990 and 2000, the educational attainment of the 25-or-older population rose
nationally, by 4 points based on the percentage with at least a bachelor’s
degree. The national proportion advanced 8 percentage points between 1980 and
2000. Most of the gain resulted from deaths in the oldest age groups, when even
a high school diploma was not common, and the addition of those born after
1950, a group with greater educational attainment.
Most
of the states with the strongest gains in the percentage of university
graduates were located along the Atlantic Coast, with most of these states
among the leaders in the share of university graduates in 2000. Almost all of
the states with the least gain in percentage of university graduates were in
the southern portion of the country, particularly in the Southwest during the
1990s. Arizona ranked tied for 41st in the change between 1990 and 2000 and
39th in the 1980-to-2000 change. The southwestern states generally still were
average on the percentage of university graduates in 2000 while the other
southern states were below average on attainment.
Educational
attainment is higher in all states among those active in the labor market. From
an economic development perspective, the educational attainment of those active
in the labor market (particularly those between 25 and 64 years of age, most of
whom have completed their educations and are not of traditional retirement age)
is of more relevance than overall attainment of the entire 25 or older
population.
This
is particularly true in Arizona, which attracts a large number of well-educated
retirees (many under the age of 65) who boost the state’s average educational
attainment but do not participate in the labor market. Thus, the most commonly
reported educational attainment figures, which are for the entire population 25
or older, present Arizona more favorably than is the reality of labor market
participants. This is the case across much of the West, which has stronger
relative educational attainments among retirees than young adults, largely due
to strong net in-migration of educated retirees and either poor educational
attainment of natives and/or strong in-migration of relatively uneducated young
people.
Educational
attainment in Arizona in the young-adult age groups of 18 to 24 and 25 to 34
was considerably less than the national average. This poor performance
partially resulted from the low educational attainments of children educated in
Arizona, but the strong net in-migration of young, poorly educated people,
especially from Mexico and Central America, also contributed. In contrast,
educational attainment among those 65 or older was higher than the national
average (see Figure IV-1).
Arizona’s
educational attainment among the younger age groups was considerably below that
of most of the competitor states (California, Colorado, Florida, Georgia,
Nevada, New Mexico, Oregon, Texas, Utah, and Washington) designated by the
Greater Phoenix Chamber of Commerce. Arizona ranked next-to-last or last among
the new economy states (California, Colorado, Connecticut, Massachusetts,
Maryland, Minnesota, New Jersey, Utah, Virginia, and Washington) identified by
the Milken Institute. However, Arizona ranked above the middle in the
retirement age group.

The
percentage of Arizona natives (those born in Arizona) with a bachelor’s degree
was only 18 percent in 2000, just half the 36 percent figure of Arizona
residents born elsewhere in the United States. The proportion of those born in
another country with a bachelor’s degree slightly exceeded that of Arizona
natives. This is an indication of the high migration rates of those with
college degrees.
Educational
Attainment Relative to Job Quality
A
strong correlation of 0.75 by state existed between job quality and educational
attainment in 2000 when attainment is measured as the percentage of college
graduates. Little correlation (0.02) was present when the attainment measure is
the percentage of high school graduates. For more information on job quality,
see Job Quality Nationally and in All States at
(www.wpcarey.asu.edu/seid/Reports.cfm).
Job
quality and educational attainment are not perfectly related for a variety of
reasons. Generally, some people will never move, whether due to family ties or
other reasons. Yet if educational attainment is encouraged in their family or
community, these residents may gain too much education for the limited
available job opportunities in their community (particularly true of less
populous areas) and accept underemployment rather than migrate to an area with job
opportunities.
Those
states with a lesser job quality than expected given their educational
attainment (as measured by university graduates) mostly are less populous
states without large urban areas nearby. Some of these states (e.g. Vermont,
Hawaii, and Montana) have considerable natural beauty. It is likely that these
states attract a certain type of educated migrant who is willing to be
underemployed in exchange for perceived noneconomic advantages.
45
Those
states with higher job quality than expected given their educational attainment
are states with an abnormally high share of jobs that are high-paying but do
not require much educational attainment, such as many mining and some
manufacturing jobs. Michigan, West Virginia, Louisiana and Texas are among the
states in this group.

GEOGRAPHICAL DISTRIBUTION
OF
THE UNIVERSITY-EDUCATED POPULATION
Summary
•
To
realize a high share of college graduates in its population, a region must
either graduate a large number of people from local institutions of higher
education or attract college graduates from other regions.
•
Labor
force participants with university degrees are highly mobile in terms of their
residence. Thus, the number of university graduates from local institutions of
higher education is not necessarily highly related to the number of college
graduates living in a community.
•
In
any community, the retention of locally educated individuals and the attraction
of highly educated people from other regions are heavily dependent on the
availability of job opportunities appropriate for those with college degrees.
Urban and natural amenities also are important to the attraction and retention
of college graduates.
•
National
studies indicate that a statistically significant relationship exists between
the number of new college graduates in a state and average educational
attainment in the state’s adult population. But the strength of this
relationship appears modest.
•
Studies
find that if an additional 100 college-bound students choose to attend college in
a given state, the long-run effect of raising the college-educated workforce in
that state will be only 5-to-10 workers. Nationally, it is college attendance
per se, not where students choose to attend, that is the crucial determinant of
educational attainment in a given workforce. Educated workers migrate in search
of occupations that align with their skill sets.
Introduction
The
college-educated share of the population depends on both demand and supply
factors. In places with an intrinsically strong local demand for educated
labor, as in places that border the nation’s capital or contain a major
financial center, employers will be able to attract workers from other states
by offering high wages. Amenities that appeal to college graduates also are
important to attract a large number of educated migrants. Alternatively, a
place may be able to assemble a highly educated population by having a large
number of people graduate from local colleges and universities (hereafter
referred to as “local production of college graduates”).
The
purpose of this chapter is to review evidence relating to the effect of local
production of college graduates on the number of adult college-educated people
that end up living in the area.
Determinants
of the Size of the University-Educated Population
Given
the high mobility of the U.S. population, and of college-educated labor in
particular, much of the variation across states in college educational
attainment derives from differences in abilities to attract college-educated
workers from other states. Some states have a comparative advantage in the use
of college-educated labor. States bordering the nation’s political and
financial capitals (Washington, D.C. and New York City), for example, long have
been important importers of educated workers. The strong demand for educated
labor in these areas derives, in large part, from an arbitrary historical
concentration of firms and institutions that make intensive use of highly
educated labor.
47
Some
states are successful in attracting educated labor not because they have an
abundance of high-paying jobs, but because they offer natural or urban
amenities that are valued by educated people. Regional and urban economists are
increasingly impressed by the important role amenities now play in U.S.
interstate migration decisions. As real incomes rise, people are choosing to
spend a greater share of their income on quality of life, either directly
through the purchases of private amenities such as fine dining or live
entertainment, or indirectly through lower wages and/or higher home prices in
areas with public amenities. Amenities are thought to be especially important
in the location decisions of highly educated people, those who can afford to
pay for them.
To
identify which amenities are most important to workers and their families,
researchers have looked both at differences in population growth rates and at
differentials in wages and land prices (the idea being that people who place a
high value on the public locational attributes of an area will be willing to
accept lower wages and/or pay more for housing to live there). Foremost among
the amenities that explain domestic U.S. migration patterns is weather.
Residents both young and old have been moving in large numbers to places with
warm winters and/or cool dry summers (Rappaport 2004). Studies of compensating
wage and home price differentials also show weather variables to be important,
especially number of heating degree days, precipitation, humidity and sunshine.
The annual differential needed to compensate someone for living in Chicago
rather than San Francisco is now thought to be around $10,000 (Costa and Kahn
2003).
Other
natural amenities that are significant in explaining wage and home price
differentials are proximity to the coast and proximity to wilderness areas and
national parks. Certain man-made, urban amenities also have been found to be
important in household location decisions. Cities that have been most
successful in attracting people are those with a rich variety of consumer goods
and services (e.g., restaurants and live entertainment venues), good schools,
and low crime (Glaeser, et al. 2001).
Despite
the high degree of mobility in the U.S. population, most people never make an
interstate move, or migrate just once. People who grow up in a state, for
example, are much more likely to live there in their adult years than is
someone drawn randomly from the national population. One particular aspect of
locational persistence that has been studied involves the decision about where to
go to college. People build relationships in college, relationships that often
have value in the workplace later in life. As a result, a person tends to work
and live in the same area that he or she went to college.
A
large number of graduates from local institutions of higher education can
translate into a large number of college-educated workers in the labor force
only if the local labor market can absorb new graduates without a substantial
decline in wages (which would end up causing workers to leave the area). The
wage sensitivity of the demand for labor depends on the nature of the skills
and degrees being acquired by graduates. Local markets for medical doctors, for
example, have little ability to absorb new graduates. Almost no relationship
exists between the number of MDs trained in an area and the number of adult
doctors living there. Producers of goods and services that can be exported out
of state, on the other hand, have the potential to absorb large numbers of new
graduates. A positive relationship between the number of graduates from local
institutions and use of college-educated labor in that area is present for
sectors producing goods and services traded across states (Bound, et al. 2004).
48
Importance
of Graduates from Local Universities
The
remainder of this chapter summarizes the empirical evidence of how the
production of college graduates influences the size of the college-educated
population. Table V:1 shows information for each state on the percent of the
adult population with at least a bachelor’s degree and the number of
undergraduate and graduate degrees awarded in the state expressed per 1,000
adult residents. The table helps to identify the states that are net importers
and net exporters of college graduates.
States
with a more favorable ranking in population share of college graduates than in
degrees awarded tend to experience net inflows of college-educated people. The
leading net importers of university graduates are New Jersey (with a difference
in rankings between degrees awarded and population share of +42), Hawaii (+30),
Alaska (+29), Washington (+27), Maryland (+23), Virginia (+23) and California
(+23). These states are successful in attracting college-educated migrants
either because they have a strong demand for educated labor or because they
offer amenities that are highly valued by educated people.
In
contrast, states with a ranking of population share that is less favorable than
their ranking based on degrees produced are likely to be net exporters of
college graduates. The largest differentials are in Indiana (-29), Iowa (-29),
Missouri (-29), North Dakota (-27), South Dakota (-22), Alabama (-21), and West
Virginia (-20). These states lack either the jobs or the quality of life
necessary to keep their graduates in state.
Arizona
is a large net recipient of migrants, both domestic and foreign, and gains more
college-educated residents through in-migration than it loses through
out-migration. The fact that Arizona has about the same ranking in share of the
population with a bachelor’s degree as it does in degrees produced per 1,000
residents is evidence not of an approximate balance between inflows and
outflows of people with college degrees but rather of the fact that a large
number of migrants without college degrees also choose Arizona as a place to
live.
A
positive and statistically significant correlation exists between the variables
in Table V:1, suggesting that local production of college degrees raises the
share of college graduates in a state’s population. Other factors also could be
affecting the share of college graduates. The simple correlation likely
underestimates the effect of degrees awarded on the share of the population
that is college educated because weather — the single most important factor
explaining U.S. migration patterns — is correlated with the geographic
distribution of U.S. colleges and universities.
As
explained by Goldin and Katz (1999), the current geographic distribution of
colleges and universities heavily reflects the settlement patterns of the late
19th and early 20th centuries and was essentially set by 1940. States with a
relatively high production of degrees are disproportionately located in the
East and upper Midwest, parts of the country with a climate generally perceived
to be undesirable. Sunbelt states, with weather that has attracted large
numbers of migrants for decades, are underrepresented by colleges and
universities. Because of this relationship between weather and degrees awarded,
a simple correlation between degrees awarded and share of the population with a
college degree will serve to understate the causal role played by local
production of degrees.
Figure
V:1 is a scatter diagram plotting degrees awarded against share of the
population with a degree, after adjusting the population share for the effect
of weather. The measure of weather used to make these adjustments was based on
Rappport’s (2004) analysis of population growth patterns and their relationship
to a variety of measures of weather and other natural amenities. His analysis
found warm winters to be the most important factor driving population
49
growth.
Rappaport used his results to rank cities on the basis of weather. These
results, in turn, were used to rank states. Those with the most favorable
weather include Arizona, California, Colorado, Florida, Hawaii, Nevada, Utah
and Wyoming. The population shares shown in Figure V:1 are adjusted by the
effects of weather. (The specific coefficient used to make the weather

to
make the weather adjustments was derived from a multiple regression of
population share on both weather quintile and degrees awarded.)
After
adjusting for weather, a statistically significant relationship exists between
degrees awarded in a state and the share of the population that is college
educated. If Arizona were to permanently raise the number of degrees awarded in
the adult population from the current rate of 10.7 per thousand to 11.7 per
thousand, the long-run effect would be to raise the share of the population
with at least a bachelor’s degree from its current level of 23.5 percent to
24.1 percent. The evidence from state-level data indicates that states with high
production of undergraduate students tend to also have a high concentration of
college graduates in their populations, but the relationship is a modest one.
Migration clearly plays an important role in determining educational attainment
in a state’s adult population.
The
scatter of points around the regression line in Figure V:1 confirms the
importance of other factors in determining average educational attainment in a
state. Some amenities that affect interstate migration may not be well
summarized by the weather variables used in the analysis.

52
For
example, Colorado has a much larger share of college graduates than expected on
the basis of its weather and the number of degrees awarded in the state.
Educated migrants may be attracted to Colorado by other amenities, such as
skiing and national parks.
More
importantly, the analysis has not accounted for factors that influence the
demand for educated labor in a state. Maryland and Virginia benefit from the
large number of jobs requiring a university degree that are located in the
vicinity of the District of Columbia. A strong financial services industry
helps attract educated workers to New Jersey and Connecticut. Massachusetts has
the most educated population in the nation, partly attributable to the large
supply of college graduates that comes out of the state’s colleges and
universities. But the state also has a strong high-tech sector that helps to
attract professional and highly-educated labor.
In
contrast, some states have a relatively weak demand for educated labor that
makes it difficult to attract or retain college graduates. Most notable are the
South Central states of Alabama, Arkansas, Louisiana and Mississippi. Low
educational attainment in these states is not simply a matter of not producing
enough college graduates.
Favorable
weather helps Arizona attract educated migrants. After adjusting for weather,
Arizona’s educational attainment is 2 percentage points below what would be
expected on the basis of the number of degrees awarded in the state. That
Arizona lies below the regression line in Figure V:1 may be a consequence more
of the attractiveness of the state as a destination for less-educated migrants
than of an inability to generate jobs to retain college graduates.
Effect
of College Location on Later Residence
An
alternative way of evaluating the contribution local universities make to
determining the size of the college-educated population in a state is to use
information on where individuals grow up, go to college, and reside later in
their adult lives. Groen (2004) used information from the Mellon Foundation’s
College and Beyond data files, which contain background information and college
records for students at 30 selected colleges and universities. Groen’s analysis
focuses on the cohort that entered college in 1976 and was later surveyed in
1996 (when respondents were approximately 38 years old). By using information
on the geographic range of schools to which individuals applied, Groen was able
to control for students that chose to go to school in a state because they
wanted to live there after graduation. In this case, simple correlations would
overstate the causal role played by college location.
Table
V:2 provides a brief summary of Groen’s results. The table shows that the
probability that a college graduate will reside in a given state in his/her
adult life depends on whether he/she resided in that state before going to
college and whether he/she attended college in the state. For example, the
number in the northwest cell means that of 100 college graduates who resided in
a given state before going to college and who also went to college in that
state, 49 out of the 100 would still be living there in their adult years.
The
most important factor determining state of residence in adult life is where a
person grows up. Comparing numbers down the columns of the table, a person is
5-to-8 times more likely to reside in a state later in life if it is his/her
home state (as defined by state of residence before college entry). The
contribution made by college location is found by comparing across rows. For a
person who grows up in a given state, he/she is 10 percentage points more
likely to reside there as an adult if he/she also went to college in the state.
Looking across the second row of the table, the results indicate that for
someone who did not grow up in a given state, he/she is only 5 percentage
points more likely to choose to reside there as an adult if he/she went to
college there.
53
The
results in Table V:2 once again point to the modest role college location plays
in decisions among educated people about where to live later in life. For every
100 in-state college-bound residents, 39 of them would choose to work and
reside in the state in their adult life even if they attend college out of
state. Policies that encourage students to remain in state when going to
college increase this number from 39 to 49.
Information
from Arizona State University alumni records indicates that 50-to-60 percent of
ASU graduates remain and work in Arizona following graduation. These numbers
are higher than the figures in the first column of Table V:2. The alumni
statistics are not directly comparable to Groen’s figures, however. The alumni
records include students who may have wanted to live in Arizona to begin with
and chose an Arizona university for that reason. In this case, the alumni
figures would overstate the role of local university attendance in the
selection of Arizona as a state of residence. Groen tried to control for this
factor by restricting his sample to individuals who applied to universities in
more than one state.
It
is also important to note that, from a policy perspective, the key feature of
the frequencies in Table V:2 is not their general size, but the differences
across columns. Alumni records say nothing about the second column of
frequencies. It may be that 60 percent rather than 49 percent of in-state
graduates from Arizona universities end up staying in state. But if it is also
the case that 50 percent rather than 39 percent of in-state residents who
attend college out of state return to Arizona to live, then policies that get
100 in-state students to remain in state when going to college still end up
increasing the college-educated workforce by only 10 students. It is college
attendance per se, not the place where students choose to attend, that is the
crucial determinant of educational attainment in a given workforce. Educated
workers migrate in search of occupations that align with their skill sets.

Introduction
Higher
education represents an economic investment with a very high return — almost
twice the size of long-run returns on stocks. Yet only one-quarter of the U.S.
population has obtained a four-year college degree. Undoubtedly, many people
under invest in education and as a result fail to reach their economic
potential. One very important role for public policy is to help more people
realize the high returns afforded by a college education.
When
people become college educated, society and the economy as a whole also
benefit. Governments function better, because educated people make good voters.
Highly educated workers also make a net positive contribution to the budgets of
state and local governments. They provide funds to the fiscal system, which
allows governments to pursue goals of social justice through public assistance
programs and programs that equalize economic opportunity. The general economy
is strengthened by having an educated workforce. Cities with highly educated
workers have been shown to be more resilient and better able to adapt to
economic change. College-educated workers also infuse an economy with knowledge
and creativity, providing a boost to productivity and wages over and above the
direct effects that an enhanced education has on their own earnings. Thus, as a
way of promoting overall growth and development in a state economy, a role
exists for public policy in higher education.
In
the language of economics, market failures exist in higher education. When left
alone, the private decisions of individuals will lead to an under investment in
higher education. While referencing points developed earlier in the report,
this concluding chapter reviews specific policy measures that have been
proposed or implemented to help address the market failures in higher
education.
Helping
People Realize their Economic Potential
Three
reasons explain why so many people fail to invest in a college education when
the benefits to the individual so greatly outweigh the costs: (1) family
financial constraints, (2) lack of academic skills necessary for success in
college, and (3) an apparent lack of knowledge or firm belief in the large
effect that a college education has on an individual's future earnings. The
appropriate policy is for dealing with underinvestment in higher education
depends on which of these barriers are most important.
55
Economists
long have recognized that the private financial system may fail to provide loan
support for investments in education in the same way that it supports
investments in physical capital. Government loan programs have been developed
to try to mitigate these financial barriers, and the evidence suggests the
programs have been highly successful. Estimates indicate that less than 10
percent of the youth population fails to complete college simply because of a
lack of financial resources. This means that additions to college financial
assistance programs are unlikely to significantly raise college educational
attainment. Cuts in assistance, on the other hand, in either loan availability
or tuition subsidies, may significantly reduce college enrollment.
Academic
ability or college preparedness now seems to be more important than financial
resources in influencing college entry and success. Unfortunately, this factor
is difficult to address. Studies of educational attainment show that success in
school depends on both the cognitive and non-cognitive skills (such as
motivation and study habits) of the student. Cognitive ability is formed very
early in life, much of it in the preschool years. Non-cognitive skills are more
malleable than cognitive skills, but they too are largely set by late
adolescence. High quality interventions in early childhood among at-risk children
have proven effective, but they are expensive. College-preparedness can also be
improved, of course, by raising the quality of elementary and secondary
schools.
Also
important as determinants of college entry and completion are family background
factors, especially parents' level of education. Uneducated parents may not
instill sufficient education goals in their children, perhaps because the
benefits seem abstract, remote, and essentially unattainable to them. Education
loans may prove ineffective in this case, since the financial benefits of
education are being undervalued. A reduction in the cost of education through
tuition subsidies, on the other hand, may help to tilt decisions in favor of
education. Efforts also can be made to disseminate information in schools that
informs students about the economic advantages of having a college degree.
While it is difficult to change family values toward education, the good news
is that any success that is achieved will cascade across generations.
Studies
indicate that the size of the increase in lifetime earnings realized by a
college graduate depends on the quality of the institution he/she attends.
Misallocations of resources also occur when a gifted student enrolls in a
low-quality college or university. As is the case in many western states,
Arizona lacks elite private colleges. Arizona has historically adopted policies
that encourage student accessibility and instructional expenditures per student
are well below the national average. Maintaining low costs allow the state to
make college education affordable and accessible, but these policies create
pressures for cost savings (such as large class sizes and a historical tendency
to hire faculty at salaries below the national average). Recent efforts to develop
Honors Colleges represent a much-needed response to the absence of high quality
college programs in the state.
While
financial constraints are no longer a major barrier to investments in
undergraduate college education, the same cannot be said for graduate study.
Because of their high earnings potential, long-term loans are available to
people who wish to become doctors, dentists, or earn other advanced degrees.
However, with high tuitions and an inability to earn income because of the time
demands of the program of study, the typical graduate student will be far in
debt when they finish. Alternatives to debt are equity-financing options first
proposed by Friedman (1955) and recently evaluated by Lleras (2005). Graduate
education can be financed by equity claims on the future earnings of the
student. The claim is paid only if the graduate obtains gainful
56
employment.
There is no onerous debt obligation for those who are unable to realize the
financial benefits of their degrees.
Economic
Development through Higher Education
An
argument can be made to include college educational attainment as an economic
development policy goal. Educated workers make a net positive contribution to
government budgets, and they help to raise the wages of all workers in an area.
While the share of the total population in Arizona that is college educated is
near the national average, the share of college graduates in the state
workforce is well below average.
One
way to realize a high share of college graduates in a state’s workforce is to
produce a large number of graduates at local universities. Examples of states
that have an above-average share of college graduates in their populations
partly because of high rates of local production include Massachusetts, New
Hampshire, New York, and Vermont. However, given the high mobility of the U.S.
population, especially among educated people, in general only a modest link
exists between local production of degrees and collegiate educational
attainment in a state’s population. Indiana, Michigan, Missouri, and North
Dakota are states that produce college graduates at a rate above the national
average but have relatively low college attainment in the general population.
So, local production alone may not be a sufficient remedy.
One
condition for local production of degrees to translate into high educational
attainment in the adult population is that students must be able to find jobs
in the state after they graduate. The local labor market must be able to absorb
new graduates without a significant drop in wages, or else workers will leave
the area. The absorptive capacity of the local economy depends upon the nature
of the skills and degrees being acquired. Local markets for medical doctors,
for example, have little ability to absorb new graduates. Statistically, there
is little connection between the number of new MDs trained in an area and the
number of adult doctors practicing there. Export-based industries, on the other
hand, have more potential to absorb new graduates. In general, a state is more
likely to generate new jobs for graduates receiving degrees in engineering and
science than it is for people acquiring skills for the delivery of local
services such as public education and health care.
In
contrast with states with stagnant population growth where labor markets for
local educated service providers are saturated, the needs in Arizona continue
to grow. The availability of local institutions (both public and private) needs
to be encouraged to help meet the local demands exerted by the explosive growth
in Arizona’s population. National data suggest that more expenditure (both
public and private) is devoted toward the production of college graduates in
other states than take place in Arizona. Public and/or private investments that
lead to tangible increases in degree attainment stand to deliver significant
returns to the students that earn the degrees and to the economies where they
ultimately live and work. And increases in the quality of the education can
lead to greater contributions to individual and societal prosperity.
Opportunities for employment in Arizona will grow with the pace of our
population, but it is growth in quality opportunities that will help retain
these high quality workers.
In
addition to local production, a state can raise educational attainment in the
population by attracting educated migrants from other states or countries.
States that have an above-average share of college graduates in their
populations despite relatively low rates of local production include Maryland,
New Jersey, Virginia, and Washington. These states have a strong demand for
educated workers that can be traced in large part to an arbitrary historical
concentration of firms and institutions that make intensive use of highly
educated labor (i.e., these states border the
57
nation’s
political capital, its financial center, or are home to the nation’s aircraft
industry). Such comparative advantages in the use of highly educated labor are
not possible for every state to replicate. But it is certainly reasonable for a
state to selectively target economic development incentives to industries with
highly educated personnel.
In-migration
of educated workers also can be encouraged by offering amenities or public
services that are especially important to educated people. The amenity that is
very important in household migration decisions is weather. Arizona is
fortunate to have warm winters and dry summers, weather characteristics that
are preferred by many people. These are natural advantages provided to the
state without cost. Educated migrants with high incomes also are attracted to
states with great natural beauty and outdoor recreational opportunities.
Arizona is well endowed with national and state parks, open space, and
beautiful landscapes. Arizona should play to these strengths by making sure
that people have easy access to parks and wilderness areas, that forests are
well managed, and that scenic beauty is maintained through such policies as the
exchange of state trust lands with high commercial value for private land with
high amenity value.
Educated
people value education and want it for their children. They will not choose to
live in places without good elementary and secondary schools. States with poor
schools do not miss out on the opportunity to attract uneducated migrants as
much as they do educated ones. Another public good that is important to people
with high incomes is transportation. Arizona has much to gain by being ahead of
the curve in transportation policy. The automobile is an important source of
external costs and economic inefficiencies. The consensus among policy experts
is that the United States fails to make drivers internalize the full costs of
driving their cars. U.S. gasoline taxes are too low, and the country fails to
make sufficient use of road pricing to relieve congestion.
Goals
of State Tuition Policy
Educational
attainment in the workforce should be an important part of a state’s broad
economic development plan. Rather than focusing on a one-dimensional agenda,
policymakers could adopt a portfolio of strategies. Increasing local production
of college graduates is an option, but it may not yield desired outcomes if
pursued in isolation. Policies that reduce incentives to migrate out of the
state, that improve amenities in the state or that nurture a business climate
that attracts businesses that employ highly educated labor may be effective. In
thinking about state university tuition policy, it may be wiser to focus on the
benefits realized by the student, not on the benefits he/she may provide to
other people since it is difficult to control state educational attainment
through tuition policy when people are so mobile. The large individual benefits
realized by a college graduate, on the other hand, are present whether or not he/she
chooses to live and work in the state in which he/she attended college.
If
state tuition subsides are used to ease student financial constraints or to
reduce the perceived cost of college for families who tend to undervalue
education, cost recovery is necessary at some point. States like Arizona are
fortunate to have amenities that encourage graduates remain in the state long
after they graduate. The taxes they pay as an adult serve to reimburse the
state for the college subsidies they receive when they are young. But the state
must continue to produce quality opportunities along with the pace of degree
recipients or, as in other states, out migration will occur.
National
studies reveal that, in many states a large share of graduates leaves the state
in pursuit of better jobs or more attractive amenities. These states must
either make tuition
58
subsidies
conditional upon subsequent state employment (the tuition subsidy is a loan
that will not have to be paid back if the student lives and works in the state
as an adult) or ensure cost recovery before the student attends college by
maintaining strict residency requirements for students to be eligible for
subsidized tuition.
