Suppose that Spain and Austria both produce fish and olives. Spain's opportunity cost of producing a crate of olives is 5 pounds of fish while Austria's opportunity cost of producing a crate of olives is 10 pounds of fish. By comparing the opportunity cost of producing olives in the two countries, you can tell thatSpain has a comparative advantage in the production of olives andAustria has a comparative advantage in the production of fish. Suppose that Spain and Austria consider trading olives and fish with each other. Spain can gain from specialization and trade as long as it receives more than5 pounds of fish for each crate of olives it exports to Austria. Similarly, Austria can gain from trade as long as it receives more than1/5 crate of olives for each pound of fish it exports to Spain. Based on your answer to the last question, which of the following prices of trade (that is, price of olives in terms of fish) would allow both Austria and Spain to gain from trade

12 pounds of fish per crate of olives

2 pounds of fish per crate of olives

9 pounds of fish per crate of olives

6 pounds of fish per crate of olives
