6. Terms of trade Suppose that Italy and Austria both produce beer and cheese. Italy's opportunity cost of producing a pound of cheese is 4 barrels of beer, while .2 Austria's opportunity cost of producing a pound of cheese is 10 barrels of beer. By comparing the opportunity cost of producing cheese in the two countries, you can tell that Italy V has a comparative advantage in the production of cheese, and Austria V has a comparative advantage in the production of beer. Suppose that Italy and Austria consider trading cheese and beer with each other. Italy can gain from specialization and trade as long as it receives more than 10 barrels v of beer for each pound of cheese it exports to Austria. Similarly, Austria can gain from trade as long as it receives more than 4 pounds V of cheese for each barrel of beer it clxports to Italy. Based on your answers to the previous question, which of the following terms of trade (that is, price of cheese in terms of beer) would allow both Austria and Italy to gain from trade? Check all that apply. 9 barrels of beer per pound of cheese 1 barrel of beer per pound of cheese 3 barrels of beer per pound of cheese 18 barrels of beer per pound of cheese
