1) Assume, for Japan, that the domestic price of automobiles without international trade
is lower than the world price of automobiles. This suggests that, in the production of
automobiles,
a.Japan has a comparative advantage over other countries and Japan will import
automobiles.
b.Japan has a comparative advantage over other countries and Japan will export
automobiles.
c.other countries have a comparative advantage over Japan and Japan will import
automobiles.
d.other countries have a comparative advantage over Japan and Japan will export
automobiles.
2) Which of the following should be held constant when calculating an income
elasticity of demand?
a.the price of the good
b.prices of related goods
c.tastes
d.All of the above should be held constant.
3) Suppose society consists of four individuals: Andy, Bill, Carl, and David. Andy has
$20,000 of income, Bill has $40,000 of income, Carl has $60,000 of income, and David
has $80,000 of income. A utilitarian would argue that
a.taking $1 from Bill and giving it to Carl would increase society's total utility.
b.taking $1 from Carl and giving it to Andy would increase society's total utility.
c.taking $1 from Carl and giving it to David would increase society's total utility.
d.taking $1 from Bill and giving it to David would increase society's total utility.
4) When economists describe preferences, they often use the concept of
a.markets.
b.income.
c.utility.
d.prices.
5) Assume that the farmer and the rancher can switch between producing pork and
producing tomatoes at a constant rate.
Without trade, the farmer produced and consumed 2 pounds of pork and 4 pounds of
tomatoes and the rancher produced and consumed 4 pounds of pork and 2 pounds of
tomatoes. Then, each person agreed to specialize in the production of the good in which
he has a comparative advantage and trade 4 pounds of pork for 6 pounds of tomatoes.
As a result,
a.the farmer gained 3 hours worth of production and the rancher gained 4 hours worth
of production.
b.the farmer gained 4 hours worth of production and the rancher gained 6 hours worth
of production.
c.the farmer gained 6 hours worth of production and the rancher gained 8 hours worth
of production.
d.the farmer gained 8 hours worth of production and the rancher gained 10 hours worth
of production.
6) In the long run a company that produces and sells covers for cell phones incurs total
costs of $2,500 when output is 1,250 covers and $4,000 when output is 1,500 covers.

a.economies of scale.
b.constant returns to scale.
c.diseconomies of scale.
d.efficient scale.

b.external cost of good x equals the private value of good x.
c.social cost of good x exceeds the private value of good x.
d.social cost of good x equals the private value of good x.
