Title: Chapter 7: Education (and positive externalities from Chapter 5)
1Chapter 7 Education (and positive externalities
from Chapter 5)
2Positive externalities
- Positive externality
- Ex fence between your and neighbors yard
- Ex research and development (RD)
- Ex. Flu shots, education
- The market failure with positive externalities
occurs - because people consider only their private
benefits - (MPB) and not the full social benefits (MSB) of
their - decisions.
-
3Consider a Research and Development example
- Firms in investing in RD consider private
benefits and costs. - Their costs of production (MC) will be upward
sloping as usual. - _________________________________________________
(assuming there are significant returns to
initial dollars placed into RD and that benefits
are eventually diminishing with additional
dollars) - In an effort to maximize profits, firms will
allocate resources such that ______________

5External benefits of RD
- However, there are marginal external benefits
(MEB) to RD. Examples include - Creation of new production technology that allows
all firms to produce more efficiently (ex
mechanization or computerization). - One medical breakthrough (equipment, drugs, new
methods) often leads to a series of new
developments or new branches of science. - _________________________________________________

the marginal external benefit (MEB) at the
efficient level (R). (Exactly as we did for
taxes!) - Commonly done for flu immunizationsshots are
free or subsidized by government to encourage
greater participation. - Empirical evidence suggests that the private
(firms) rate of return on RD is roughly
__________. The social rate of return is
approximately __________ Clearly, there are
significant external benefits.
10Public education and positive externalities
- A stable and democratic society is impossible
without a minimum degree of literacy and
knowledge on the part of most citizens and
without widespread acceptance of some common set
of values. Education can contribute to both. In
consequence, the gain from the education of a
child accrues not only to the child but also to
other members of the society. -
11Positive externalities in Public education
- _________________________________ educated
persons are more actively involved in their
communities (including volunteerism) and have
higher voter participation rates and may help
improve the quality of the democratic process. - _______________________________ higher literacy
is negatively related to crime rates (or at least
violent crimes). More educated less crime. - ________________________________ an educated work
force is a more productive workforce education
is thought to be necessary for the creation of
new technologies that may increase economic
growth. - The presence of spillover benefits suggests that
education should be subsidized in accordance with
its external benefits. However, the US has free
and compulsory K-12 education which cannot be
justified on efficiency grounds alone!
12Should there be public education? At what level?
Typical arguments
- 1. Strongest rationale for public education vs.
private education revolves around
__________________________________________________
__________________________________________________
_ - The suggestion is that if all education were
privatized that schools would focus on the
productivity skill set which increases wages for
students and not necessarily place emphasis on
the social conventions, citizenry, etc that often
have small marginal benefits to individuals but
have significant external benefits to society. - Evidence suggests these the citizenry benefits
accrue early in education and may provide
rationale for public education at the primary
(elementary) level but less so at the secondary
level or higher education
13Arguments continued
- 2. ___________________________________________
assuming that education is a normal good (as
income increases, demand increases) families with
higher incomes will provide more education than
families with lower income. - ____________________________refers to situations
in which low-income persons have a chance to
raise their incomes (be upwardly mobile in terms
of income). - This is a widely held belief in democratic
societiesthat all persons should have access to
opportunities for income mobility. - lack of public education reduces income mobility
resulting in a larger gap between the rich and
the poor. Public education should theoretically
level the playing field among its citizens by
providing equal access to all families.
14Arguments for public education continued
- 3. Another argument in favor of public education
focuses on financial ability to pay for education
and __________________________________________ - In the absence of public education, families
would have to self-finance all education
resulting in large inequities between the rich
and the poor - if a family had a talented child and they wanted
to make sure their child had access to the best
education they would need to borrow money to
finance her education. Credit markets are
unlikely to lend such funds (asymmetric
informationbanks cannot tell if a given child is
a good investment or not) - .
15Arguments for public education
- 4. _______________________________________
- Even if such credit existed, would a family
necessarily choose to pay for education for a
child if it meant sacrificing consumption for the
rest of the family. Optimal provision of private
education is not likely. - As we will discuss later, a similar argument is
used to against public education suggesting that
public education crowds out private education
and families will opt to send their kids to the
free public school instead of investing in a
better-quality, private school.
16Arguments against public education
- 1. Government provision of K-12 education is
inefficientcosts are too high given educational
attainments (outcomes) - the single largest expenditure item for state and
local governments is education. - They spend on average __________of their budgets
to provide this government service. - The US spends more than any other nation per
pupil around ______________ for K-12 education. - The US spends more than ______________per pupil
when including higher educationmore than any
other nation in the world.

19Arguments against Public Education-continued
- 2. Although US spending levels on education are
the highest in the world, US educational outcomes
(K-12) are only average internationally and in
some cases are much lower than countries which
far less wealth. - Scientific Literacy The United States
________________ OECD countries in scientific
literacy, and the U.S. score of 489 fell below
the OECD average of 500 (OECD 2007). - _________________________ of U.S.
fifteen-year-olds do not reach the baseline level
of science achievement. This is the level at
which students begin to demonstrate the science
competencies that will enable them to use science
and technology in life situations (OECD 2007)
20US education statistics continued
- Mathematics Literacy The United States ranks
_________________of OECD countries in mathematics
literacy, and the average score of 474 fell well
below the OECD average of 498. Scores have not
measurably changed since 2003, when the United
States ranked 24th of 29 countries (OECD 2007b). - ____________________________of American
fifteen-year-olds performed below the baseline
level of mathematics proficiency at which
students begin to demonstrate the kind of skills
that enable them to use mathematics actively in
daily life (OECD 2007b) - Reading Literacy The United States ranked of
__________________ OECD countries in reading
literacy, and with a score of 495, came in near
the OECD average of 500
21Arguments against public education
- 3. _______________________________________________
___________________________________ - _________________________refers to situations in
which public provision of a good substitutes for
private provision of a good (reducing demand for
privately provided goods). - Such crowding out may result in lower educational
outcomes.

23Graph summary
- In the absence of public education each person
maximizes utility by selecting the highest
indifference curve attainable resulting in Eo
education purchased. - If public education is provided at a fixed level,
Ep, then the consumer re-evaluates his utility
maximization and can now reach a higher
indifference curve by going to public school. - Private education is crowded out by the
existence of public education. - This doesnt have to be the case, depending on
preferences, individuals may not reduce private
education and no crowding out may occur.
24No Crowding Out occurs if there is a strong
preference for larger quantities of education

25ARGUMENTS AGAINST PUBLIC EDUCATION CONTINUED
- 4. _______________________________________________
___________________________________________ - This results in tremendous inequity between
rich and poor geographic areas. - Many believe states should find alternative
mechanisms, such as income taxes (as done in
Iowa), to more fairly distribute funds to
schools. - PBS video
26What factors are used to measure educational
outcomes?
-
- Difficulty is that test scores alone do not tell
you much. Students in different school districts
may have other family/socioeconomic
characteristics that impact learning. -
-
-
-
- Evidence suggests there is no direct relationship
between spending and outcomes.
27what are the leading determinants in educational
success of students
- Clearly, money is not the answer. Spending per
pupil has more than doubled in the last 25 years
and educational outcomes are no better (and in
many cases worse) on average. -
- Information here can be biased. Sometimes
wealthier school districts have smaller classes
and better educational outcomes. However, this
could be because of different socioeconomic
factors and not necessarily small class size. - Information may be biased in the other direction
too. Sometimes we have small classes for students
with learning disadvantages. Their test scores
may be lower suggesting small class size has a
negative impact on learning. - Literature suggests that to reduce the
teacher-student ratio by 10 (go from 30 students
to 1 teacher to 27 students to 1 teacher) costs
an additional 700 per student. - Costs are very high and sometimes reduces the
experience level of teachers (hire on more new
teachers) - Within the literature, the single most important
factor for a childs educational success is
_________________________________________
28School vouchers
- In essence, a school voucher is money given to
parents of a child attending a K-12 school that
may be applied to private education instead of
going to the school to which the child is
assigned. - The notion of school vouchers were first
introduced (in a modern way) in the 1950s by
Milton Friedman. - Friedman, a Nobel Prize Economists (1976) created
a book series entitled Free to Choose in 1980.
The series examined how free markets encourage
prosperity and included an entire section on
school vouchers. PBS created a series based on
Free to Choose with Friedman narrating. This
started the modern trend toward usage of school
vouchers. - www.ideachannel.tv (you can view the original
broadcast as volume 6 What is wrong with our
schools?)
29Friedman and school vouchers
- According to Friedman, school vouchers would
increase competition among school and improve
cost efficiency. - Schools would have incentives to
- Schools would have incentives to
- Parents would be free to choose where there
children went to school increasing incentives for
parents to become more involved in the
educational process. - Friedman suggests in 1980 that the centralized
school system is run by bureaucrats that may have
different goals than those of parents and that
parents do not have power in the system to make
significant changes.
30Graph of how vouchers work
31Arguments from Proponents of school vouchers
- _____________________________ vouchers allow
parents the freedom of choice so they may more
closely match their educational choices with
their tastes. - ____________________________________________
suggests that people already individually
determine this through their location decision.
Families locate in certain areas that have the
proper mix of property taxes (for education) and
educational quality. - However, property taxes are used to supply an
array of government services and people make
their location decision based on many attributes,
not just schooling therefore this self-sorting
mechanism may not work perfectly - _______________________________ results in
greater cost efficiency and better educational
outcomes (quality). - This includes greater educational outcomes of
public schools which must now improve to keep
their funding. - Remember, school funding per pupil has doubled
since 1980 but test scores have not improved. - Further, administrative staff in public schools
has grown by 65 since 1970 and the number of
students has only grown by 2 (US Dept of
Education 2006).
32Proponents of vouchers continued
- 3. Vouchers allow students in failing schools an
escape hatcha way to improve their educational
quality and income mobility - 4. Vouchers provide parents a stronger voice in
their childrens education (curriculum,
methodology, etc). Since they may easily move
their child away from one school to another
better option, schools are more likely to be open
to parental input.
33Argumentsopponents of school vouchers
- ___________________________________________the
positive externalities associated with civic
engagement, etc may be minimized by schools to
focus on specialty skill sets (tastes) and
undercuts the benefit of common programming. - With private education there is no educational
standard or way of enforcing standards across
schools - Opponents cite examples of schools focusing on
the arts and not having comprehensive
programming such as basic reading and math
skills. - Proponents of vouchers say this could easily be
handled by setting minimum standards and giving
standardized tests. - ______________________________________________as
the best students leave failing schools for
better opportunities the worst students remain
reducing educational quality. - cream skimming
- Private schools have many school voucher
applicants but will only take the good students
and not all students
34Arguments against vouchers continued
- 3. __________________________________________ if
motivated parents differ from disinterested
parents along income, race, or ethnic lines you
will observe a sorting of students along these
lines. - proponents of vouchers say the educational
freedom will result in less segregation as lower
income students can move to better school
districts. - 4. _______________________________________________
______________________________________ there are
cost efficiencies in current school districts and
much like a monopoly, if you increase competition
by providing lots of smaller schools the
economies of scale are foregone resulting in
higher costs. - how can a rural area support enough schools for
adequate competition when there is not sufficient
demand (children).
35Opponents of vouchers continued
- 5. _______________________________Vouchers are
based on per pupil spending but this
disadvantages families with children requiring
special education - students with developmental and learning
disabilities require additional monitoring,
diagnostic testing, and accommodations. The per
pupil spending level is not enough to provide
adequately for these children. - 6. ___________________________________ many
private schools have a religious affiliation.
Many people believe it is unfair and/or
unconstitutional to spend government dollars on
religious education.
36School vouchers in practice today
- School vouchers have been used in other countries
for many years (including Chile, Hong Kong,
Sweden, Norway, Ireland). - In most cases, the voucher is
- In some states, it is the average spending
level per child in the state. - The school voucher can be used at any qualifying
private school to fully or partially cover
tuition expense. - Much controversy over what schools should
qualify. - Heated debate over religious private education
such as Catholic private schools and separation
of church and state.
37US Vouchers
- In the US, the first school voucher system was
done in Milwaukee, Wisconsin in 1990. - This was a small scale voucher system in which
families earning income no more than 175 of the
poverty line could receive a voucher worth 3200
that could be used at any non-religious private
school. - As of 2007, the program has expanded and 15,000
students in Milwaukee are using vouchers. - Other areas with vouchers include
- Washington D.C. (called the DC Opportunity
Scholarship Program) - Cleveland, Ohio (after much legal battling over
constitutional issues) - Florida (Florida Opportunity Scholarship
Program)allowed students in failing schools to
attend other schools of their choicedeclared
unconstitutional in 2005. Still facing legal
issues and back on the political agenda currently
38Evidence on effectiveness of vouchers
- Evidence is mixed with regard to effectiveness of
vouchers (measured in terms of educational
success or higher scores on exams, dropout rates,
etc). - Part of the problem is accounting for intangible,
and often, immeasurable differences among
students such as ambition, parental influence,
etc. - Students that use vouchers are probably more
motivated than those that do not. - Also, in some states or voucher areas, private
school select admits from an applicant pool most
likely taking the best students.
39Milwaukee voucher program data
- Much of the empirical evidence is based on the
Milwaukee pilot program for a few reasons - participating private schools had to accept any
voucher - If the private school was oversubscribed
meaning that there were more applicants than
open spots then they had to determine admission
via random lottery - This means that empirically you could now compare
those that wanted to use vouchers in two
different environments private school vs. public
school without bias - Control group
- Treatment group
40Early Findings by rouse (1998) and others
- Rouse There was an increase in educational
success within the treatment group - An increase in math scores by ____________________
__that students were in private school relative
to the control group - Other measures in reading, etc were not
statistically different - Findings in Colombia Voucher Program which has
over 125,000 students (Angrist et al 2002) - Students that won vouchers via lottery were
_____________________________________. - Students scored higher on standardized tests
- The cost to government was ___________________and
wages for the winners increased between
____________________
41Other types of programs and policies that provide
public school incentives
- _______________________________ schools must
measure performance of students to ensure they
are meeting or exceeding educational standards - (Handshek and Raymond 2004) evidence
- As of 2002, 25 states in US directly linked
student promotion to the next grade of graduation
to performance on state and local assessment
tests - 18 states rewarded teachers and/or administrators
for successful student performance on exams - 20 states penalized teachers and administrators
for subpar student performance - Found a direct link between rewards/penalties and
school performancesizeable improvements in test
scores
42No child left behind (NCLB)
- This idea of school accountability was formalized
into US law in 2001 with the No Child Left
Behind Act of 2001 (President Bush) - Based on the idea of standards-based educational
reform - Each state sets its own standard (assessment test
and minimum compliance) - States that do not submit assessment plans and
outcomes will have their federal funding
rescinded - Federal funding for education NCLB increased
initially from 17.4 billion in 2001 to 24.4
billion in 2007 (40 increase) in part to pay for
assessment, to pay for new and improved school
programming, and to fund reward programs, etc.
43Proponents of nclb
- Suggest that NCLB
- Schools must provide detailed reports to
parenting on the teacher qualifications in the
school where their child attends -
- Creates common standards among all school
districts in a state - Forces schools identify at risk populations and
target programs at those students -
- provides school choice for students in failing
schools (schools receiving a grade of Fstudents
can move to a new district)
44Criticisms of no child left behind
-
- Implication is that teachers narrowly focus
education on the tested items enabling students
to perform well on test and not a broad education - There is empirical evidence which suggests that
this is the casestudents do well on the
standardized test but when given an alternative
test, scores are significantly reduced. -
- Jacob (2002) found that in both Chicago and
Florida school systems many low performing
students were reclassified as special education
students or disabled so scores would not be
counted in the school average. - Jacob and Levitt (2003) found evidence that
teachers may cheat (providing answers) if they
are rewarded financially for improved student
performance.
45Criticisms of NCLB
- 3. States may actual lower standards to ensure
school districts meet standards to maintain their
federal funds - 4. Talented students may receive less funding and
funding is shifted to at risk populations - 5. Less funding for arts and elective courses as
more resources are focused on the basics of math,
science, and reading. - 6. NCLB requires military recruiter access to
schools facilitating military enrollment
46Charter schools and magnet schoolsschool choice
alternative
- ______________________ are small, independent
schools that are not subject to many of the
regulations imposed on traditional public
schools. - Operated by private enterprises with own internal
regulations - They do not have to follow same restrictive
hiring procedures for teachers - More flexibility in curriculum, hiring and firing
of administrative staff. - Charter schools often have a particular
focuseither in terms of the learning objectives
or the student demographic - Ex Beardstown, IL Charter School for English as
a Second Language Students
47Magnet schools
- _______________________ special public schools
set up to attract talented students or students
interested in a particular subject or teaching
style - School of the arts
- Schools of Science and Technology
- Magnet schools are still public schools and must
abide by administrative procedures and policies. - Empirical evidence of educational improvement in
magnet schools is mixed or inconclusive. - Most studies find no improvement or no
statistically significant improvement - Where small gains in improvement exist is when
there is a large degree of competition.
