Title: Public Spending and Public Choice
1Chapter 5
- Public Spending and Public Choice
2Three areas of concentration
- Explain how market failures, such as
externalities, might justify economic functions
of government - 2. Distinguish between private and public goods
and explain the nature of the free-rider problem - 3. Describe the political functions of government
that entail its involvement in the economy
3When the market fails it is a double edge sword
- Market Fails if not optimal mix.
- Optimal Mix of Output Most desirable
combination of output attainable with existing
resources, technology and social values. - Market Failure
- An imperfection in the market mechanism that
prevents optimal outcomes.
4Market FailureIs this evident in todays market?
- market moves resources from one industry to
another. (price directs resources) (demand
responds) (price moves the resources then to
another demand choice) (at this point
(competition begins to prevail to level the
prices)

5What a Price System Can and Cannot Do (cont'd)
- Market Failure
- A situation in which the unrestrained market
economy leads to too few or too many resources
going to a specific economic activity - Prevents economic efficiency and individual
freedom - Is addressed by public policy (government)
6In real words?
- Not enough public parks
- Not enough care for environment
- Not enough welfare
- Not enough healthcare
- Too much separation between top 10 income
earners and median income earners - Not adequate security within our borders.
- Too many immigrants.
7Specific Example
- Hypothetical
- No government regulation exists.
- Steel producing plant moves into the
neighborhood. - Production of steel emits dirt, smut, unhealthy
air throughout the neighborhood. - This is an externality the spillover is the
dirty air borne by the citizens. - Who pays for this cost? Citizens- company making
a profit on steel.
8Socially Optimal Amount (Output)
- Sometimes, the socially optimal amount is
referred to as the efficient amount.
9Correcting for Externalities (cont'd)
- Market failure an example
- Market failure occurs
- Steel mill does not pay for the clean air
- Costs of production have spilled over to the
residents (third parties) - Lower production cost
- More steel is produced than would otherwise be
the case
10Figure 5-1 External Costs and Benefits, Panel (a)
11- Market failure (forces of S D not leading us
to BEST point on ppc Who decides what is defined
as BEST? - Enter. Government intervention!
- Did you hear the words tax and subsidy?
- Will they perform magic?
12Correcting for Externalities
- Externalities
- Occur when the consequences of an economic
activity spill over to affect third parties - Third Parties
- Parties who are not directly involved in a given
activity or transaction - Property Rights
- Rights of an owner to use and exchange property
13Correcting for Externalities (cont'd)
- Externalities are examples of market failures.
- Pollution is an example of a negative
externality. - Inoculations generate external benefits.
14Figure 5-1 External Costs and Benefits, Panel (b)
15Correcting for Externalities
- Resource misallocations of externalities
- External costsmarket overallocates
- External benefitsmarket underallocates
- Government can correct negative externalities
- Special taxes (i.e. a pollution tax or effluent
fee) - Regulation
16Correcting for Externalities (cont'd)
- How the government can correct positive
externalities - Government financing and production
- Subsidies
- Regulation
17There are two main types of economic instruments
used in environmental policy, both of which aim
to provide an incentive to use resources
sustainably
- Price-based measures use charges, taxes and
subsidies to persuade polluters to reduce their
discharges. - Rights-based measures "create rights to use
environmental resources, or to pollute the
environment, up to a pre-determined limit, and
allowing these rights to be traded"
18 Other Economic Functions of Government
- Providing a legal system
- Promoting competition
- Providing public goods
- Ensuring economy wide stability
19The Other Economic Functions of Government
(cont'd)
- Providing a legal system
- Enforcing contracts
- Defining and protecting property rights
- Establishing legal rules of behavior
20The Other Economic Functions of Government
(cont'd)
- Promoting competition
- Market failure may occur if markets are not
competitive. - Antitrust legislation
- Monopoly power
21The Other Economic Functions of Government
- Antitrust Legislation
- Laws that restrict the formation of monopolies
and regulate certain anticompetitive business
practices - Monopoly
- A firm that can determine the market price, in
the extreme case is the only seller of a good or
service
22The Public SectorGovernments role.
- Questions to ponder
- What is Public Sector?
- When do markets fail?
- Should government step in?
- Can people ride free in public sector?
23- Governments Enter the Market to assure
- 1. Public Goods
- 2. Externalities (positive or elimination of
negative) - 3. Market power
- 4. Equity
24Two concepts to remember
- Public goods can be equally consumed by all no
restrictions - Skateboarding in the park Terrorists can also
go to the park Illegal immigrants can go to
school - Private goods consumption by one person excludes
consumption by another.. - ( my doughnut my car etc)
25But, if mix of output gets totally out of whack.
Government takes over.
26Translation
- If government and/or the consumer was not acting
as a watchdog. Would corporations be diligent
about utilizing the proper mix of resourcesIf
they are, can they compete? - Telecommunications Industry?
- Does that always mean regulation increased?
- Could it mean that consumer sovereignty switches
to another desire BUT what about things like
energy would we really know if the provider was
efficient? What about government-driven choices?

28Methods to Reduce Pollution
- Government sets pollution standards
- Market environmentalism Government allocates
pollution permits and then allows them to be
bought and sold
29Government Allocates Pollution Permits (allows
market to operate)
- Agreement that a certain area can handle
acceptable amt of pollution. - The amount is quantified, then parceled into
permits that polluters bid for in auction. - Can buy and sell pollution rights among companies
bidding. - Allows some companies to pollute more than
others ones that are really good sometimes get
perks like tax benefits others have opportunity
to pass on to their consumers (TXU)
30- Government reallocates resources if 1) market
produces wrong amount of certain gS and 2)
market fails to allocate resources to some gs
that are in best interest of society. - What are externalities? costs or benefits of a
market activity borne by a third party. - Spilloversan action when one individual or group
harms the property of others without their
consent.
31Examples of spillovers
- Throwing trash in someones back yard
- Burning ties in the alley
- Playing your stereo loudly at 300 a.m.
- Businesses dumping wastes, sludge into rivers
- People trashing the beach or highway.
- Electric Companies burning phosphorous fuels
32Spillover Examples that perpetrate on others
- Calling police when loud party of teenagers next
door (actions of teens imposing unwanted cost on
neighbor) - Living in downstairs apartment.. Having upstairs
neighbors doing Tai Bo when they get off work at
400 a.m. - Calling the city when a neighbor doesnt keep his
yard mowed on regular basis.
33Externalities can be positive or negative
- Homeowners keep lawns immaculate (benefits the
neighborhood) - Scientific study for polio vaccine (others
benefit beyond scientists recognition) - Education. How would this be a benefit?
34How can spillovers be corrected?
- Most obvious way is Legislation.
- To prohibit
- To heavily tax the specific product and
manufacturer. Tax would be derived to allow for
off-setting the clean-up cost. (Super Fund is
example) - Subsidize both consumers or producers
- Tax incentives if reduction of pollution and
compliance adhered to, taxes reduced.
35A Corrective Tax Gone Wrong
- Government may miscalculate external costs and
impose a tax that moves the supply curve from S1
to S3 instead of from S1 to S2. - As a result, the output level will be farther
away from the socially optimal output than before
the corrective tax was applied. - Q3 is farther away from Q2 than Q1 is from Q2.

39Public Spending and Transfer Programs
- Publicly subsidized healthcare
- Medicare
- Began in 1965
- Pays hospital and physicians bills for U.S.
residents over 65 with public monies - 2.9 of earnings taxed/ no cap
- Second biggest domestic program in existence
- Medicaid
- Subsidizes people with lower incomes
40 The Economic Effects of Medicare Subsidies
Subsidy M customers pay Pd for quantity
Qm Providers receive price Ps for supply the
good.
41Collective Decision Making The Theory of Public
Choice
- Government or Political Goods
- Goods (and services) provided by the public
sector - Majority Rule
- Collective decision making, decisions based on
more than 50 - Proportional Rule
- If 10 of dollar votes cast for blue cars, 10
of output is blue
42Equity or perhaps better stated as
Inequity.(ensuring market economy)
- 1)Inadequate income (redistribute to have-nots)
- 2) Merit goods (everyone entitled to some minimum
of food,clothing, shelter) In-kind transfers in
food stamps, housing vouchers, health clinics) - 3)Social Security and unemployment compensation
protect peoples economic security by providing
money when they retire or are unable to work.
43- Opportunity cost if government provides health
care, private sector cannot compete. Government
crowds out the private . - Remember, the largest opportunity cost of an
item supplied by government is the best
alternative use that could have been made of the
resources required to provide that good.
44We are at a crossroads-Which path should the
U.S. take?
- Free Markets?
- Private markets?
- Government Regulated Markets?
- Government Driven Markets?
- Government Run Markets?
45Thats All Folks!
