1) Suppose a tax of $3 is imposed on each new garden hose that is sold, resulting in a
deadweight loss of $22,500. The supply curve is a typical upward-sloping straight line,
and the demand curve is a typical downward-sloping straight line. Before the tax was
imposed, the equilibrium quantity of garden hoses was 100,000. We can conclude that
the equilibrium quantity of garden hoses after the tax is imposed is
a. 75,000.
b. 85,000.
c. 90,000.
d. 95,000.
2) Senator Hubris wants to pass a law that would require all monopolistically
competitive firms to operate at their efficient scale. If this law were to pass and be
enforced, we would expect that monopolistically competitive firms would
a.see their profits increase.
b.break even.
c.lose money.
d.not really be affected by the law.
3) Suppose that a steel factory emits a certain amount of air pollution, which constitutes
a negative externality. If the market does not internalize the externality,
a.the supply curve would adequately reflect the marginal social cost of production.
b.consumers will be required to pay a higher price for steel than they would have if the
externality were internalized.
c.the market equilibrium quantity will not be the socially optimal quantity.
d.producers will produce less steel than they otherwise would if the externality were
internalized.
4) Carol Anne makes candles. If she charges $20 for each candle, her total revenue will
be
a.$1,000 if she sells 100 candles.
b.$500 if she sells 25 candles.
c.$20 regardless of how many candles she sells.
d.$200 if she sells 5 candles.
