Timeline
On Monday, we went through topics related to direct and indirect governments
Today We finish Unit 2 by looking at Chapter 7
Topics in education Time for review (30-45 minutes)
More problems Your questions
Publicly-provided education Real annual spending per
pupil on public elementary and secondary schooling has increased by 81% from 1980 to 2006
Why is this so? Citizen preferences? Positive externalities of
education? Generates more taxes
as adults Socialization reasons
School Year Real expenditure per pupil (2004 dollars)
1980 $5,016
1985 $6,057
1990 $7,102
1995 $7,322
2000 $8,068
2005 $8,998
2006 $9,100

Citizen preferences
Some people believe that each person has a right to a minimum level of education Recall social utility function
At low levels of education, social welfare could be min{educi}
Basic education needed to be functional in society Equitability issues
Prevention of de facto caste system if only the rich can afford education
Positive externalities
An economist would go further, claiming that there are positive externalities in education Less likely to have civil unrest More income to tax later in life Ability to understand public policy
Debate exists as to the level of positive externalities Empirical findings are not conclusive
What about higher education? In-state students at California’s public
colleges and universities have their educations substantially subsidized
Are there positive externalities from higher education? Argument against
Diminishing externalities from education Arguments in favor
Research externalities Inefficient loan market for students
Diminishing marginal returns argument The diminishing marginal returns argument
claims that the positive externalities are greatest for the early years of education
With this argument, the amount of subsidized higher education may be above the optimal quantity
Research externalities
Higher education in some fields provides substantial amounts of externalities Research that benefits many people in society
This leads to the question: Should different fields of study in college have different subsidization levels? Hard sciences may deserve a higher subsidy Fields with no research externalities would get
small subsidy by this argument
Potential negative consequences Although there may be positive externalities
with college education, there is another consequence Increased income inequality
Subsidized education results in the rich getting richer, leading to increased income inequality
With increase in income inequality, social instability can occur
Government provision of education It appears that the government is justified in
subsidizing education How should education be provided?
Public Private Some public and some private
Public provision of education
Assume a simple model of education Each student goes to public or private school (but not both) Parents try to maximize utility Public school quantity is fixed Public school price is free Per-hour quality of public and private school is equal
This assumption will be relaxed later on Total taxes collected on each family does not change with
publicly-provided education

Reality check on education
In reality, most people maximize utility by sending their kids to public school
If desired education level is above ep, parents can supplement education with after-school and weekend activities Music lessons Learning a second language Private tutoring

Once again, some parents may send their kids to public school and supplement education with private activities
Quality of public education
Quality of education is hard to quantify Besides the obvious aspects of class size
and total spending, there are different criteria that affect education Unionization of teachers Parents’ choices of their kids’ curriculum Size of school School-sponsored sports and activities
Unionization of teachers
Many public school districts have unionized teachers
Pro Keep standards of educators high
Cons Higher wages than in competitive market
Less money for other spending Layoff order
Usually based on seniority, not quality, of educator
Parents’ choices of their kids’ curriculum Parents are heterogeneous in the wants for
their kids’ education Private schools often provide more
specialized choices Religion Montessori More challenging curriculum than public school (in
some cases) Charter schools (more on this later)
Parents’ choices of their kids’ curriculum Pros of private school
More choices No big bureaucracy to deal with
Cons of private school Less public oversight Additional cost
Size of school
Pros of big schools Lower administrative cost per student Ability to offer more classes
Example: Tagalog class in a school with a significant Filipino population
Fewer school sites needed Cons of big schools
Some students have longer distances to travel “Getting lost in the crowd”
School-sponsored sports and activities Pros of big schools
More sports and activities offered Higher quality for spectators
Cons of big schools Fewer students “make the team” Competition to make the team can be fierce
Wanda Holloway Daughter tried out for cheerleading at age 13 Asked brother-in-law to kill another girl’s mother Convicted of solicitation of capital murder
Total spending
The United States is near the top of per-pupil spending
Test scores of US students is not near the top in many internationally-administered tests

More recently, the US has past the Swiss in spending
Class size and total spending
A common assumption is that as more money is spent, school quality goes up
Is this always the case?
Class size and total spending
Example: Increased spending to reduce class size
Pro Fewer students per teacher
Con New teachers Lower average quality than
current teachers
Class size and total spending
Does increased spending actually lead to higher school quality?
Evidence is mixed Some programs in some schools appear to use
additional resources well There is evidence that some schools may not use
additional resources well
Empirical work on education
Be careful while reading through the “Empirical Evidence” subsections in the textbook
Make sure that you understand the difference between correlation and causation Refer to Chapter 2, if needed
Example of empirical work
How much does education increase earnings? Recall diminishing marginal returns
Greatest returns to disadvantaged children in early years Justification for programs like First 5 California and Head
Start Low returns from increased K-12 educational
spending on the margin Each year of schooling increases earnings by an
estimated 5-11 percent
Cost-benefit analysis of spending We can calculate the direct costs and
benefits of additional school spending Card and Krueger (1996) estimate that a 10
percent reduction in class size results in increased earnings between 0.4-1.1 percent
Peltzman (1997) uses Card and Krueger’s results to do a cost-benefit analysis Various assumptions made 3 percent and 7 percent discount rates used
Results from Peltzman (1997) Net present value of costs are higher than the
benefits Are there other benefits that are not measured
here? Only increased earnings are accounted for below
How are schools changing?
By many measures, public school quality in the US is decreasing
Three ways to try to reverse this trend Charter schools School vouchers School accountability
Charter schools
Increased independence in spending and hiring
Allows for competition between charter and regular public schools
Some evidence shows that the introduction of charter schools increases quality of ALL public schools
School vouchers
Each parent or guardian of a child receives a voucher
The voucher is redeemed by the school in exchange for providing education
School vouchers
Pro Competition
Poor public schools Improve or go out of business
Cons Information gathering of schools is costly Reduction of positive externalities of education Rich families may use vouchers more than poor families
Some poor families may not be able to afford private school with vouchers
Vouchers effectively increase income of middle-class and rich families that already send their kids to private schools
School vouchers
Replies to cons Vouchers can be geared toward low-income
students Private schools would still need to meet
curriculum guidelines Positive externalities Current research will help shape the debate
on vouchers The main question: Who benefits and who loses
from school vouchers?
School accountability
Schools are monitored No Child Left Behind (2001)
Some schools get “report cards” evaluating their performance
Some schools have financial incentives linked to test outcomes
School accountability
Pros Reduction in bureaucracy Increased focus on core learning Gives easy access of each school’s performance
to the entire population
School accountability
Cons No incentive for certain types of learning
Art, music, physical education, emotional development “Teaching to the test” Arbitrary mandates make some good schools look
bad Gaming the system
Increased suspensions Increased use of special education Cheating
Education and employment
There are different theories about the direct effectiveness of education Direct learning Screening
Employers need to try to determine how much of education is direct learning, and how much is screening
Education and employment
Various messages are sent to employers by finishing a certain level of education “I have learned everything needed to finish this
level of education” “I am intelligent enough to finish this education,
which probably means I am smarter than somebody without my level of education”
“I am using this level of education to send a signal that I have other good qualities that you are looking for; others that do not finish this level of education can say the same thing”
Education and employment
Many jobs require a minimum level of education to be considered for a job M.D. degree to be hired as a medical doctor License for many specialized fields
Real estate Pilot
High school or college diploma for many entry-level jobs
Summary: Publicly-provided education There are arguments in favor of providing
basic education to all children free of charge Crowding out predicted for some families
Public spending on education has increased in recent decades, but some indications of student performance have decreased
Recent proposals for reform try to increase public school performance Financial incentives and competition
