Chapter 3/Interdependence and the Gains from Trade ❖ 41
38. Which of the following statements is not correct?
a.
Trade allows for specialization.
b.
Trade has the potential to benefit all nations.
c.
Trade allows nations to consume outside of their production possibilities curves.
d.
Absolute advantage is the driving force of specialization.
39. Assume that Greece has a comparative advantage in fish and Germany has a comparative advantage in cars.
Also assume that Germany has an absolute advantage in both fish and cars. If these two countries specialize
and trade so as to maximize the benefits of specialization and trade, then
a.
the two countries’ combined output of both goods will be higher than it would be in the absence of
trade.
b.
Greece will produce more fish than it would produce in the absence of trade.
c.
Germany will produce more cars than it would produce in the absence of trade.
d.
All of the above are correct.
40. Suppose that a worker in Radioland can produce either 4 radios or 1 television per year and a worker in Teev-
eeland can produce either 2 radios or 5 televisions per year. Each nation has 100 workers, and each country
specializes according to the principle of comparative advantage. If Radioland trades 100 televisions to Teev-
eeland in exchange for 100 radios each year, then each country's maximum consumption of new radios and
televisions per year will be
a.
higher than it would be in the absence of trade because of the gains from trade.
b.
the same as it would be in the absence of trade.
c.
less than it would be in the absence of trade because neither country is specializing in the product in
which it has a comparative advantage.
d.
less than it would be in the absence of trade because Teeveeland has an absolute advantage in both
goods and so it cannot benefit by trading with Radioland.
41. Suppose that a worker in Radioland can produce either 4 radios or 1 television per year, and a worker in Teev-
eeland can produce either 2 radios or 4 televisions per year. Each nation has 100 workers. Also suppose that
each country completely specializes in producing the good in which it has a comparative advantage. If Radio-
land trades 100 radios to Teeveeland in exchange for 100 televisions each year, then each country's maximum
consumption of new radios and televisions per year will be
a.
100 radios, 300 televisions in Radioland and 300 radios, 100 televisions in Teeveeland.
b.
300 radios, 100 televisions in Radioland and 100 radios, 300 televisions in Teeveeland.
c.
200 radios, 100 televisions in Radioland and 100 radios, 200 televisions in Teeveeland.
d.
300 radios, 100 televisions in Radioland and 100 radios, 400 televisions in Teeveeland.

worker in Sylvania can produce either 2 units of corn or 6 units of wheat per year. Each nation has 10 workers.
Without trade, Freedonia produces and consumes 30 units of corn and 10 units of wheat per year. Sylvania
produces and consumes 10 units of corn and 30 units of wheat. Suppose that trade is then initiated between
the two countries, and Freedonia sends 30 units of corn to Sylvania in exchange for 30 units of wheat. Free-
donia will now be able to consume a maximum of
a.
30 units of corn and 30 units of wheat.
b.
40 units of corn and 30 units of wheat.
c.
40 units of corn and 20 units of wheat.

43. Suppose that a worker in Freedonia can produce either 6 units of corn or 2 units of wheat per year, and a
worker in Sylvania can produce either 2 units of corn or 6 units of wheat per year. Each nation has 10 workers.
Without trade, Freedonia produces and consumes 30 units of corn and 10 units of wheat per year. Sylvania
produces and consumes 10 units of corn and 30 units of wheat. Suppose that trade is then initiated between

44. Suppose that a worker in Agland can produce either 10 units of organic grain or 2 units of incense per year,
and a worker in Zenland can produce either 5 units of organic grain or 15 units of incense per year. There are

and consumes 100 units of grain and 20 units of incense per year. Zenland produces and consumes 50 units of
grain and no incense per year. If each country made the decision to specialize in producing the good in which
it has a comparative advantage, then the combined yearly output of the two countries would increase by
a.
30 units of grain and 100 units of incense.
b.
30 units of grain and 150 units of incense.

worker in Oatland can grow either 5 bushels of corn or 50 bushels of oats per year. There are 20 workers in
Cornland and 20 workers in Oatland. If the two countries do not trade, Cornland will produce and consume
400 bushels of corn and 100 bushels of oats, while Oatland will produce and consume 60 bushels of corn and
400 bushels of oats. If each country made the decision to specialize in producing the good in which it has a
comparative advantage, then the combined yearly output of the two countries would increase by
a.
280 bushels of corn and 450 bushels of oats.

46. Suppose that a worker in Freedonia can produce either 6 units of corn or 2 units of wheat per year, and a
worker in Sylvania can produce either 2 units of corn or 6 units of wheat per year. Each nation has 10 workers.
For many years the two countries traded, each completely specializing according to their respective compara-
tive advantages. Now, however, war has broken out between them and all trade has stopped. Without trade,
Freedonia produces and consumes 30 units of corn and 10 units of wheat per year. Sylvania produces and
consumes 10 units of corn and 30 units of wheat. The war has caused the combined yearly output of the two
countries to decline by
a.
10 units of corn and 10 units of wheat.

ken out between them and all trade has stopped. Without trade, Caninia produces and consumes 10 blankets
and 40 meals per day and Felinia produces and consumes 25 blankets and 5 meals per day. The war has
caused the combined daily output of the two countries to decline by
a.
15 blankets and 35 meals.
