1) DeShawn has spent $600 purchasing and repairing an old fishing boat, which he
expects to sell for $900 once the repairs are complete. DeShawn discovers that, in
addition to the $600 he has already spent, he needs to make an additional repair, which
will cost another $400, in order to make the boat worth $900 to potential buyers. He can
sell the boat as it is now for $400. What should he do?
a.He should sell the boat as it is now for $400.
b.He should keep the boat since it would not be rational to spend $1,000 on repairs and
then sell the boat for $900.
c.He should complete the repairs and sell the boat for $900.
d.It does not matter which action he takes; the outcome is the same either way.

b. $1,000.
c. $3,500.
d. $7,000.
4) Suppose a country begins to allow international trade in steel. Which of the
following outcomes will be observed regardless of whether the country finds itself
importing steel or exporting steel?
a.The sum of consumer surplus and producer surplus for domestic traders of steel
increases.
b.The quantity of steel demanded by domestic consumers increases.
c.Domestic producers of steel receive a higher price for steel.
d.The losses of the losers exceed the gains of the winners.
5) Assume that Maya and Miguel can switch between producing mixers and producing
toasters at a constant rate.
Assume that Maya and Miguel each has 60 hours available. If each person divides
his/her time equally between the production of mixers and toasters, then total
production is
a.8 mixers and 16 toasters.
b.3.5 mixers and 6 toasters.
c.15 mixers and 9 toasters.
d.20 mixers and 12 toasters.
6) Table 17-13
Two home-improvement stores (Lopes and HomeMax) in a growing urban area are
interested in expanding their market share. Both are interested in expanding the size of
their store and parking lot to accommodate potential growth in their customer base. The
following game depicts the strategic outcomes that result from the game. Increases in
annual profits of the two home-improvement stores are shown in the table below.
Refer to Table 17-13. Increasing the size of its store and parking lot is a dominant
strategy for
a.Lopes, but not for HomeMax.
b.HomeMax, but not for Lopes.
c.both stores.
d.neither store.
7) Private decisions about consumption of common resources and production of public
goods usually lead to an
a.efficient allocation of resources and external effects.
b.efficient allocation of resources and no external effects.
c.inefficient allocation of resources and external effects.
d.inefficient allocation of resources and no external effects.
8) If macaroni and cheese is an inferior good, then an increase in
a.the price will cause the demand curve for macaroni and cheese to shift to the left.
b.the price will cause the demand curve for macaroni and cheese to shift to the right.
c.a consumer's income will cause the demand curve for macaroni and cheese to shift to
the left.
d.a consumer's income will cause the demand curve for macaroni and cheese to shift to
the right.
9) Scenario 12-3
Suppose Roger and Regina receive great satisfaction from their consumption of
cheesecake. Regina would be willing to purchase only one slice and would pay up to $8
for it. Roger would be willing to pay $11 for his first slice,$9 for his second slice, and
$5 for his third slice. The current market price is $5 per slice. Assume that the
government places a $4 tax on each slice of cheesecake and that the new equilibrium
price is $9. How much tax revenue will be generated from sales to Regina and Roger?
a.zero
b.$4
c.$8
d.$12
10) A country club usually only allows members to purchase tickets for its celebrity
golf tournament, but the club is considering allowing non-members to purchase tickets
this year. The demand and supply schedules are as follows:

celebrity golf tournament, then what will be the equilibrium price?
a.$10
b.$15
c.$20
d.$25
11) Which of the following conditions is characteristic of a monopolistically
competitive firm in long-run equilibrium?
a.P > demand and P = MR
b.ATC > demand and MR = MC
c.P > MC and demand = ATC
d.P < ATC and demand > MR

b.its average cost and its marginal cost are equal.
c.its average cost is less than its marginal cost.

13) Figure 13-3
The changing slope of the total cost curve reflects
a.decreasing average variable cost.
b.decreasing average total cost.
c.decreasing marginal product.
d.increasing fixed cost.
