Suppose that France and Sweden both produce oil and wine. France's opportunity cost of producing a bottle of wine is 5 barrels of oil while Sweden's opportunity cost of producing a bottle of wine is 11 barrels of oil.

By comparing the opportunity cost of producing wine in the two countries, you can tell that(Sweeden or France) has a comparative advantage in the production of wine and (Sweeden or France) has a comparative advantage in the production of oil.

Suppose that France and Sweden consider trading wine and oil with each other. France can gain from specialization and trade as long as it receives more than(1 barrels or 1/11 barrels or 1/5 barrels or 5 barrels or 11 barrels) of oil for each bottle of wine it exports to Sweden. Similarly, Sweden can gain from trade as long as it receives more than(1 barrels or 1/11 barrels or 1/5 barrels or 5 barrels or 11 barrels) of wine for each barrel of oil it exports to France.

Based on your answer to the last question, which of the following prices of trade (that is, price of wine in terms of oil) would allow both Sweden and France to gain from trade?Check all that apply.

9 barrels of oil per bottle of wine

17 barrels of oil per bottle of wine

10 barrels of oil per bottle of wine

2 barrels of oil per bottle of wine
