42 ❖ Chapter 3/Interdependence and the Gains from Trade
42. 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
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
30 units of corn and 30 units of wheat.
40 units of corn and 30 units of wheat.
40 units of corn and 20 units of wheat.
10 units of corn and 40 units of wheat.

40 units of corn and 30 units of wheat.
40 units of corn and 20 units of wheat.
10 units of corn and 40 units of wheat.
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
20 workers in Agland and 10 workers in Zenland. Currently the two countries do not trade. Agland produces
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
30 units of grain and 100 units of incense.
30 units of grain and 150 units of incense.
50 units of grain and 90 units of incense.
50 units of grain and 130 units of incense.
45. Suppose that a worker in Cornland can grow either 40 bushels of corn or 10 bushels of oats per year, and a
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
280 bushels of corn and 450 bushels of oats.
340 bushels of corn and 500 bushels of oats.
360 bushels of corn and 520 bushels of oats.
360 bushels of corn and 640 bushels of oats.
