1. Why Nations Trade Chapter 18

2. Concepts Affecting Trade  Absolute advantage – exists when one nation can produce goods more cheaply than another nation.  Comparative advantage – ability of a nation to specialize in the production of the good for which it has the greatest comparative advantage or lowest opportunity cost.  Competitive advantage – economic competitive of a nation reflected in the absolute cost of a given good in a given market at a particular point in time.

Example of Absolute Advantage Units of Ouput/Unit of Labor United States Tons/man hour Mexico Tons/man hour Wheat102 Coffee46 The U.S. is the most efficient producer of wheat while Mexico is the most efficient producer of coffee. With trade, the U.S. would specialize in wheat and exchange part of its surplus for coffee. Mexico would specialize in coffee and trade part of the surplus for wheat The U.S. is the most efficient producer of wheat while Mexico is the most efficient producer of coffee. With trade, the U.S. would specialize in wheat and exchange part of its surplus for coffee. Mexico would specialize in coffee and trade part of the surplus for wheat Page 515

Example of Comparative Advantage Units of Ouput/Unit of Labor United States Tons/man hour Mexico Tons/man hour Wheat102 Coffee43 Mexico has the absolute disadvantage in producing both goods because its productivity fell by 50% from the previous example). While the U.S. is more productive in both goods, its relative advantage is greatest in wheat (5.0>1.33). The U.S. therefore has a comparative advantage in wheat while Mexico has the least comparative disadvantage in coffee, or comparative advantage in coffee. Mexico has the absolute disadvantage in producing both goods because its productivity fell by 50% from the previous example). While the U.S. is more productive in both goods, its relative advantage is greatest in wheat (5.0>1.33). The U.S. therefore has a comparative advantage in wheat while Mexico has the least comparative disadvantage in coffee, or comparative advantage in coffee. Page 515

Page 520 Through trade, the U.S. specializes in wheat at point B, trades 50 tons of wheat to Mexico for 45 tons of coffee, and consumes more of both goods at point C (45 tons of coffee and 150 tons of wheat). By comparing point C with point A, we see that the U.S. has gained from trade. Through trade, the U.S. specializes in wheat at point B, trades 50 tons of wheat to Mexico for 45 tons of coffee, and consumes more of both goods at point C (45 tons of coffee and 150 tons of wheat). By comparing point C with point A, we see that the U.S. has gained from trade.

They would trade 45 tons of coffee for 50 tons of wheat, and consumer more of both goods (50 tons of wheat and 15 tons of coffee at point C’) than it could at point A’.
