France and England both produce wine and cloth under conditions of constant opportunity costs. France can produce 150 units of wine if it produces no cloth, and 100 units of cloth if it produces no wine. England can produce 50 units of wine if it produces no cloth, and 150 units of cloth if it produces no wine. When international trade takes place, each country specializes in the production of the good in which it has a comparative advantage—1 unit of wine exchanges for 1 unit of cloth—and France exports 50 units of wine. We can conclude that France produces ________ units of wine and ________ units of cloth, and that France consumes ________ units of wine and ________ units of cloth.
