SOLUTIONS TO TEXT PROBLEMS:
Quick Quizzes
1. Since wool suits are cheaper in neighboring countries, Autarka would import suits if it were to
allow free trade.
2. Figure 1 shows the supply and demand for wool suits in Autarka. With no trade, the price of
suits is 3 ounces of gold, consumer surplus is area A, producer surplus is area B + C, and
surplus, and reduce the gain in total surplus.
Figure 1
3. Lobbyists for the textile industry might make five arguments in favor of a ban on the import
of wool suits: (1) imports of wool suits destroy domestic jobs; (2) the wool-suit industry is
vital for national security; (3) the wool-suit industry is just starting up and needs protection
from foreign competition until it gets stronger; (4) other countries are unfairly subsidizing
their wool-suit industries; and (5) the ban on the importation of wool suits can be used as a
bargaining chip in international negotiations.
In defending free trade in wool suits, you could argue that: (1) free trade creates jobs in
some industries even as it destroys jobs in the wool-suit industry and allows Autarka to enjoy
a higher standard of living; (2) the role of wool suits for the military may be exaggerated; (3)
government protection is not needed for an industry to grow on its own; (4) it would be good
for the citizens of Autarka to be able to buy wool suits at a subsidized price; and (5) threats
against free trade may backfire, leading to lower levels of trade and lower economic welfare
for everyone.

5. The arguments given to support trade restrictions are: (1) trade destroys jobs; (2) industries
threatened with competition may be vital for national security; (3) new industries need trade
easily identify new industries that are worth protecting; (4) if countries subsidize their
exports, doing so simply benefits consumers in importing countries; and (5) bargaining over
trade.

b. While there are many possible answers, one correct answer is: the national-security
argument and the infant-industry argument. The economic rationale for the national-
security argument is that if the product is necessary for national security, we should not
rely on imports for the production of the good. The economic rationale against the
national-security argument is that the proponents of trade restrictions may exaggerate
government to foresee which industries will be profitable and worth protecting.
5. a. Figure 9 shows the market for T-shirts in Textilia. The domestic price is $20 Once trade is
allowed, the price drops to $16 and three million T-shirts are imported.
Figure 9
$14 million.
Producer surplus declines by area A. Thus, producer surplus falls by $8 million.
