1) Figure 7-16
Suppose the price of the good is $450. Then, on the first unit of the good that is sold,
producer surplus is
a.$250, and on the second unit of the good that is sold, producer surplus is $100.
b.$250, and on the second unit of the good that is sold, producer surplus is $150.
c.$350, and on the second unit of the good that is sold, producer surplus is $100.

is $20, and Karla's willingness to pay Roland to mow her lawn is $28.
Assume Roland is required to pay a tax of $3 each time he mows a lawn. Which of the
following results is most likely?
a.Karla now will decide to mow her own lawn, and Roland will decide it is no longer in
his interest to mow Karla's lawn.
b.Karla is willing to pay Roland to mow her lawn, but Roland will decline her offer.
c.Roland is willing to mow Karla's lawn, but Karla will decide to mow her own lawn.
d.Roland and Karla still can engage in a mutually-agreeable trade.

outcomes when an externality is present.

externality is present.
c.government intervention cannot lead to an efficient outcome when an externality is
present.

5) Refer to Figure 9-15. For the saddle market, area B represents
a.government's revenue from the tariff.
b.the deadweight loss of the tariff.
c.the increase in producer surplus, relative to the free-trade situation, as a result of the
tariff.
d.None of the above is correct.
6) Producer surplus is the amount a seller is paid minus the cost of production.
a.True
b.False
7) Figure 8-7
The vertical distance between points A and B represents a tax in the market.
As a result of the tax, buyers effectively pay
a.$32 for each unit of the good, and sellers effectively receive $24 for each unit of the
good.
b.$32 for each unit of the good, and sellers effectively receive $16 for each unit of the
good.
c.$24 for each unit of the good, and sellers effectively receive $16 for each unit of the
good.
d.$28 for each unit of the good, and sellers effectively receive $20 for each unit of the
good.
8) Energy drinks and granola bars are normal goods. When the price of energy drinks
decreases, the income effect causes
a.the consumer to feel richer, so the consumer buys more granola bars.
b.the consumer to feel richer, so the consumer buys fewer granola bars.
c.granola bars to be relatively more expensive, so the consumer buys more granola bars.
d.granola bars to be relatively less expensive, so the consumer buys fewer granola bars.
9) Table 14-5
The table represents a demand curve faced by a firm in a competitive market.
For this firm, the marginal revenue of the 12th unit is
a. $9.
b. $10.
c. $11
d. The marginal revenue cannot be determined without knowing the total revenue when
11 units are sold.
10) Labor-market discrimination is evident when
a.wages of individuals differ on the basis of some recognizable attribute that is
unrelated to productivity.
b.wage rates differ for similar jobs.
c.consumers prefer to shop at some stores, and not at others.
d.wages reflect workers' human capital.
11) In his 1951 book Social Choice and Individual Values, Arrow's perfect voting
system satisfies all of the following properties except

results from the tax is smaller, the
a.larger is the price elasticity of demand.
b.smaller is the price elasticity of supply.
c.larger is the amount of the tax.
d.All of the above are correct.
14) Diminishing marginal utility suggests that
a.more is always preferred to less.
b.the well-being of society is maximized when the distribution of income is equal.
c.the poor are less efficient at spending money than the rich.

18) Suppose the demand schedule in a market can be represented by the equation
QD=500-10P, where QD is the quantity demanded and is the price. Also, suppose the
supply schedule can be
represented by the equation QS=200+10P, where QS is the quantity supplied.
