Lectures


Outline

5a Market Failures

I. Structural Adjustment Policies

1. Privatization
2.
Promotion of Competition
3. Limited and Reoriented Role for Government
4. Price Reform: Removing Controls
5.
Joining the World Economy
6. Macroeconomic Stability

II. Review: Supply, Demand, and Efficiency [See: The supply and demand model and allocative efficiency]

A. WHAT WE GET:

1. Goal of businesses: Maximize Profits
2. Therefore,they will produce where:
  • the Market Equilibrium quantity
  • the quantity where Qs=Qd
  • the is "what we get"

 

  • Graphically:

     

    3. Assumptions: pure capitalism (for what is capitalism see: chapter 2)

B. WHAT WE WANT: ALLOCATIVE EFFICIENCY

1. Review :
a. Allocative Efficiency
definition - using our limited resources to produce:
  • The quantity of goods and services that maximizes society's satisfaction
  • using resources to produce more CDs that people want and fewer cassette tapes that they don't want
  • no shortages and no surpluses

b. Benefit-Cost Analysis

definition -
the selection of ALL possible alternatives where the marginal benefits are greater than the marginal cost

select all where: MB > MC
up to where: MB = MC
but never where: MB < MC

c. Allocative Efficiency is achieved where: MSB=MSC

(1) define Marginal Social Benefits (MSB)

(2) define Marginal Social Costs (MSC)

(3) therfore if society gets

all quantities where: MSB > MSC
up to where: MSB = MSC
but never where: MSB < MSC

this will be the quantity where society's Satisfaction will be maximized or the allocatively efficient quantity

2. Graphically:

 

 

C. THEREFORE:

1. Businesses will produce the profit maximizing or market equilibrium quantity - the quantity where Qd=Qs

2. Society wants the allocatively efficient quantity - the quantity where MSB=MSC

3. WHAT WE GET = WHAT WE WANT if:

b. Market Demand = Marginal Social Benefits (D=MSB)
1. law of diminishing marginal utility
2. assuming no positive externality (or spillover benefit)s D=MSB

c. Market Supply = Marginal Social Costs (S=MSC)

1. law of increasing costs
2. assuming no negative externality (or spillover cost)s S=MSC

D. Competitive Markets and Allocative Efficiency (MSB=MSC)

1. if there are no negative externality (or spillover cost)s, then S = MSC,

2. if there are no positive externality (or spillover benefit)s, then D = MSB,

3. Graphically:

 

 

4. Then: WHAT WE GET = WHAT WE WANT and market economies achieve allocative efficiency

 

In a market economy with no positive externality (or spillover benefit)s and no negative externality (or spillover cost)s:

the profit maximizing or market equilibrium quantity
(what we get)

WILL BE THE SAME AS

the allocative efficient quantity
(what we want)

III. Market Failures (when MSB do not equal MSC):

5b The Economic Role of Government and Government Finance

III. Review: Capitalism, Markets, and Efficiency

A. Capitalism and Limited Government
  1. private property and economic growth
  2. markets and prices
  3. role of self interest
  4. freedom of enterprise and choice
  5. competition = capitalism
  6. limited role for government

B. Why limited government?

 

1. Businesses will produce the profit maximizing or market equilibrium quantity - the quantity where Qd=Qs

2. Society wants the allocatively efficient quantity - the quantity where MSB=MSC

3. WHAT WE GET = WHAT WE WANT if:

a. Market Demand = Marginal Social Benefits (D=MSB)
1. law of diminishing marginal utility
2. assuming no positive externality (or spillover benefit)s D=MSB

b. Market Supply = Marginal Social Costs (S=MSC)

1. law of increasing costs
2. assuming no negative externality (or spillover cost)s S=MSC

4. Competitive Markets and Allocative Efficiency (MSB=MSC)

a. if there are no negative externality (or spillover cost)s, then S = MSC,

b. if there are no positive externality (or spillover benefit)s, then D = MSB,

c. Graphically:

 

 

4. Then: WHAT WE GET = WHAT WE WANT and market economies achieve allocative efficiency

 

In a market economy with no positive externality (or spillover benefit)s and no negative externality (or spillover cost)s:

the profit maximizing or market equilibrium quantity
(what we get)

WILL BE THE SAME AS

the allocative efficient quantity
(what we want)

 

IV. Economic Functions of Government

A. Five Reasons for Government Involvement
1. legal and social framework
2. maintaining competition
3. redistribution of income
(correcting market failure to achieve equity)
4. reallocation of resources
(correcting market failure to achieve efficiency)
5. stabilizing unemployment and inflation and promoting economic growth

B. Legal and Social Framework

providing the legal foundation and a social environment conducive to the effective operation of the market system

C. Maintaining Competition

1. review competition
a. large numbers
b. free entry and exit

2. the problem with monopolies

a. higher prices
b. smaller quantities
C. allocative and productive inefficiency

3. role of government

a. preventing monopolies -- antitrust laws
b. regulating monopolies -- natural monopolies

D. Correcting Market Failure to Achieve Equity

1. define equity
2. how does equity affect society's satisfaction?
3. examples of income distribution
US: Table
World:

4. Growing inequality in the US

5. role of government

a. transfer payments
b. market intervention
c. progressive income taxes

E. Correcting Market Failure to Achieve Allocative Efficiency

Four circumstances (there are more) when a market economy results in allocative inefficiency:
  • Lack of Competition (Microeconomics class)
  • Negative Externalities
  • Positive Externalities
  • Public goods

 

F. Stabilization (to be studied in units 2 and 3)

1. unemployment
2. inflation
3. role of government
a. fiscal policy
b. monetary policy

D. Regressive, Proportional, and Progressive Taxes

WASHINGTON

House Dems hit on sales tax proposal

House Democrats plan to attack GOP candidates nationwide on their support of a national sales tax proposal, hoping the issue will help their attempt to take over the House.

Democrats think a national sales tax would mean that lower-income families will pay more of the country's tax burden and have been running advertisements attacking GOP candidates for supporting the idea. "We think that Republican candidates and Republican incumbents who are supporting this legislation must respond to their constituents about how they're going to deal with moving the tax burden," said Rep. Robert Matsui, D-Calif.

Several friends have asked: "Why should we pay sales tax on lift tickets? I don't want to pay a $14 sales tax on my season pass. Don't we pay enough already?" Perhaps a better question would be: "How might we use the revenue?"

Summit County has a highly regressive tax structure in the form of its sales tax on food for home consumption, i.e. the tax we pay on groceries at the supermarket. In most states, such a tax is in fact illegal. According to the USDA, a budget minded family of four averages $153/week on groceries or $7,966/year. Our 5 percent groceries sales tax adds about $400 to that cost. For someone earning $10/hour, that is about one week's wages. Clearly, the sales tax on food places a disproportionate burden on the working poor who are the foundation of our tourist industry.

Imposing a 4 percent sales tax on lift tickets would provide a revenue stream that could be used to reduce or eliminate groceries tax while maintaining a neutral position on overall sales tax collections. A 4 percent sales tax on lift tickets would help shift the burden from those who can least afford it to those who can and help make Summit County a more family friendly place to live.

Other possible uses? How about funding affordable housing initiatives specifically earmarked for police, school teachers, firemen, and other persons vital to our community. Affordable daycare continues to be a major concern, especially with the impending loss of Kinderhut triggered by VRI actions. Do we really want to continue providing VRI with a free ride on sales taxes and 6.7 million dollar subsidies to build gondolas? I think not. It is time for a lift ticket tax.

b. average tax rates

3. Fed. Income Tax Rates

TAX SCHEDULE:
http://www.irs.gov/

For 2012, tax brackets are as follows for an individual in the U.S.:
10% on taxable income from $0 to $8,700

15% on taxable income over $8,700 to $35,350

25% on taxable income over $35,350 to $85,650

28% on taxable income over $85,650 to $178,650

33% on taxable income over $178,650 to $388,350

35% on taxable income over $388,350

 

E. International Comparisons

F. Distribution of the Tax Burden

G. Government Growth

1. ways to measure government size

 

2. growth of TOTAL government expenditures

 

 

3. BUT:

 

a. purchases vs. transfer payments
(exhaustive and nonexhaustive expenditures)
much of the growth has been the growth of transfer payments

 

b. growth of government expenditures AS A % OF GDP

Notice how goverernment spending as a % of total spending DID NOT DOUBLE since 1965, but it is growing
