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 comparative 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.
b. 20 units of corn and 20 units of wheat.
c. 30 units of corn and 30 units of wheat.
d. 40 units of corn and 40 units of wheat.
