Comparative advantageDiffering opportunity costs

consumption possibilities through trade are greater than a country’s production possibilities.

Textbook Problem Solutions

1. The opportunity cost of producing food instead of textiles is one yard of textiles per 7/4 = 1.75 pounds of food. A pound of food has an opportunity cost of 4/7 = .57 yards of textiles.

Textbook Problems

2. Examination of the no-trade input/output table indicates that Country X has an absolute advantage in the production of food and textiles. Country X can “trade off” one unit of production needed to produce 17 pounds of food for five yards of textiles. Thus, a yard of textiles has an opportunity cost of 17/5 = 3.40 pounds of food, or a pound of food has an opportunity cost of 5/17 = .29 yards of textiles. Analogously, Country Y has an opportunity cost of 5/2 = 2.50 pounds of food per yard of textiles, or 2/5 = .40 yards of textiles per pound of food. In terms of opportunity cost, it is clear that Country X is relatively more efficient in producing food and Country Y is relatively more efficient in producing textiles. Thus, Country X (Y) has a comparative advantage in producing food (textile) is comparison to Country Y (X).

2. When there are no restrictions or impediments to free trade the economic-well being of the citizens of both countries is enhanced through trade. Suppose that Country X shifts 20M units from the production of textiles to the production of food where it has a comparative advantage and that Country Y shifts 60M units from the production of food to the production of textiles where it has a comparative advantage. Total output will now be (90M x 17 =) 1,530M pounds of food and [(20M x 5 =100M) + (90M x 2 =180M) =] 280M yards of textiles. Further suppose that Country X and Country Y agree on a price of 3.00 pounds of food for one yard of textiles, and that Country X sells Country Y 330M pounds of food for 110M yards of textiles. Under free trade, the following table shows that the citizens of Country X (Y) have increased their consumption of food by 10M (30M) pounds and textiles by 10M (10M) yards.
