2. Supply, Demand, and Government Policies

In
a free, unregulated market system,
market forces establish equilibrium prices
and exchange quantities.
While equilibrium conditions may be
efficient, it may be true that not everyone is
satisfied.
One of the roles of economists is to use their
theories to assist in the development of
policies.

3. Price Controls...

Are
usually enacted when
policymakers believe the market
price is unfair to buyers or sellers.
Result in government-created price
ceilings and floors.

Price Ceilings & Price Floors
Price Ceiling
A legally
established maximum price at which a
good can be sold.
Price Floor
A legally
established minimum price at which a
good can be sold.

5. Price Ceilings

Two outcomes are possible when the
government imposes a price ceiling:
The
price ceiling is not binding if set above
the equilibrium price.
The price ceiling is binding if set below the
equilibrium price, leading to a shortage.

8. Effects of Price Ceilings

A binding price ceiling creates ...
shortages because QD > QS.
Example:
Gasoline shortage of the
1970s
nonprice rationing
Examples:
Long lines, Discrimination

9. Lines at the Gas Pump

In 1973 OPEC raised the price of
crude oil in world markets. Because
crude oil is the major input used to
make gasoline, the higher oil prices
reduced the supply of gasoline.
What was responsible for the long
gas lines?
Economists blame government
regulations that limited the price oil
companies could charge for gasoline.

12. Rent Control

Rent
controls are ceilings placed on the
rents that landlords may charge their
tenants.
The goal of rent control policy is to help
the poor by making housing more
affordable.
One economist called rent control “the
best way to destroy a city, other than
bombing.”

15. Price Floors

When the government imposes a
price floor, two outcomes are
possible.
The
price floor is not binding if set below
the equilibrium price.
The price floor is binding if set above the
equilibrium price, leading to a surplus.

18. Effects of a Price Floor

A price
floor prevents supply and
demand from moving toward the
equilibrium price and quantity.
When the market price hits the
floor, it can fall no further, and the
market price equals the floor price.
Harcourt, Inc. items and derived items copyright © 2001 by Harcourt, Inc.

19. Effects of a Price Floor

A binding price floor causes . . .
a surplus because QS >QD.
nonprice rationing is an alternative
mechanism for rationing the good,
using discrimination criteria.
Examples: The minimum wage, Agricultural
price supports
Harcourt, Inc. items and derived items copyright © 2001 by Harcourt, Inc.

20. The Minimum Wage

An important example of a
price floor is the minimum
wage. Minimum wage laws
dictate the lowest price
possible for labor that any
employer may pay.

24. What are some potential impacts of taxes?

25. Taxes

Tax
incidence is the study of who
bears the burden of a tax.
Taxes result in a change in market
equilibrium.
Buyers pay more and sellers receive
less, regardless of whom the tax is
levied on.

31. The Incidence of Tax

In
what proportions is the burden of
the tax divided?
How do the effects of taxes on sellers
compare to those levied on buyers?
The answers to these questions
depend on the elasticity of demand
and the elasticity of supply.

35. Summary

Price
controls include price ceilings
and price floors.
A price ceiling is a legal maximum on
the price of a good or service. An
example is rent control.
A price floor is a legal minimum on
the price of a good or a service. An
example is the minimum wage.
Harcourt, Inc. items and derived items copyright © 2001 by Harcourt, Inc.

36. Summary

Taxes
are used to raise revenue for
public purposes.
When the government levies a tax on
a good, the equilibrium quantity of
the good falls.
A tax on a good places a wedge
between the price paid by buyers and
the price received by sellers.
Harcourt, Inc. items and derived items copyright © 2001 by Harcourt, Inc.

37. Summary

The
incidence of a tax refers to who
bears the burden of a tax.
The incidence of a tax does not
depend on whether the tax is levied
on buyers or sellers.
The incidence of the tax depends on
the price elasticities of supply and
demand.
