Chapter 3/Interdependence and the Gains from Trade ❖ 87
9. Belarus has a comparative advantage in the production of linen, but Russia has an absolute advantage in the
production of linen. If these two countries decide to trade,
Belarus should export linen to Russia.
Russia should export linen to Belarus.
trading linen would provide no net advantage to either country.
Without additional information about opportunity costs, this question cannot be answered.
10. Suppose that a worker in Boatland can produce either 5 units of wheat or 25 units of fish per year, and a work-
er in Farmland can produce either 25 units of wheat or 5 units of fish per year. There are 10 workers in each
country. Political pressure from the fish lobby in Farmland and from the wheat lobby in Boatland has pre-
vented trade between the two countries on the grounds that cheap imports would kill the fish industry in Farm-
land and the wheat industry in Boatland. As a result, Boatland produces and consumes 25 units of wheat and
125 units of fish per year while Farmland produces and consumes 125 units of wheat and 25 units of fish per
year. If the political pressure were overcome and trade were to occur, each country would completely special-
ize in the product in which it has a comparative advantage. If trade were to occur, the combined output of the
two countries would increase by
25 units of wheat and 25 units of fish.
50 units of wheat and 50 units of fish.
75 units of wheat and 75 units of fish.
100 units of wheat and 100 units of fish.
11. Suppose that a worker in Boatland can produce either 5 units of wheat or 25 units of fish per year, and a work-
er in Farmland can produce either 25 units of wheat or 5 units of fish per year. There are 30 workers in each
country. No trade occurs between the two countries. Boatland produces and consumes 75 units of wheat and
375 units of fish per year while Farmland produces and consumes 375 units of wheat and 75 units of fish per
year. If trade were to occur, Boatland would trade 90 units of fish to Farmland in exchange for 80 units of
wheat. If Boatland now completely specializes in fish production, how many units of fish could it now con-
sume along with the 80 units of imported wheat?
12. In which of the following cases should the United States produce more noodles than it wants for its own use
and trade some of those noodles to Italy in exchange for wine?
Americans know less than Italians know about cooking noodles.
The United States has an absolute advantage over Italy in producing noodles.
Italy has a comparative advantage over the United States in producing wine.
The opportunity cost of producing a gallon of wine is the same for Italy as it is for the United
States.
