Copyright© 2003 Southwestern/Thomson Learning All rights reserved. Why Trade? ●Reasons countries benefit from foreign trade ♦They can import resources they lack at home. ♦They can import goods for which they are a relatively inefficient producer. ♦Specialization sometimes permits economies of large-scale production. ●Reasons countries benefit from foreign trade ♦They can import resources they lack at home. ♦They can import goods for which they are a relatively inefficient producer. ♦Specialization sometimes permits economies of large-scale production.

Copyright© 2003 Southwestern/Thomson Learning All rights reserved. The Law of Comparative Advantage ●One country is said to have an absolute advantage over another in the production of a particular good if it can produce that good using smaller quantities of resources than can the other country.
10
Copyright© 2003 Southwestern/Thomson Learning All rights reserved. ●One country is said to have a comparative advantage over another in the production of a particular good if it produces that good less inefficiently than the other country. The Law of Comparative Advantage
11
Copyright© 2003 Southwestern/Thomson Learning All rights reserved. The Law of Comparative Advantage ●The law of comparative advantage applies even if one country is at an absolute disadvantage relative to another country in the production of every good.
12
Copyright© 2003 Southwestern/Thomson Learning All rights reserved. The Law of Comparative Advantage ●Both countries gain from trade even if one of them is more efficient than the other in producing everything.
13
Copyright© 2003 Southwestern/Thomson Learning All rights reserved. The Law of Comparative Advantage ●The Arithmetic of Comparative Advantage ♦When countries differ in the relative efficiency with which they produce different goods: ■Both world output and the welfare of each country can be increased if: ●Each country specializes in producing the goods for which it has a relative advantage; ●And then trades with the other. ●The Arithmetic of Comparative Advantage ♦When countries differ in the relative efficiency with which they produce different goods: ■Both world output and the welfare of each country can be increased if: ●Each country specializes in producing the goods for which it has a relative advantage; ●And then trades with the other.

Copyright© 2003 Southwestern/Thomson Learning All rights reserved. Comparative Advantage: “Cheap Foreign Labor” ●A country can benefit from trade, even if wages in the other country are considerably lower than its own wages. ?
20
Copyright© 2003 Southwestern/Thomson Learning All rights reserved. Supply, Demand, and Pricing in World Trade ●In a two-country supply-demand model without trade restrictions: ♦The price of a good must be the same in both countries ♦The quantity of a good exported from one country must equal the quantity imported by the other ●In a two-country supply-demand model without trade restrictions: ♦The price of a good must be the same in both countries ♦The quantity of a good exported from one country must equal the quantity imported by the other

Tariffs, Quotas, and Other Interferences with Trade ●Countries can reduce imports by setting tariffs or quotas. ●They can promote exports by subsidizing export goods. ●Countries can reduce imports by setting tariffs or quotas. ●They can promote exports by subsidizing export goods.

Copyright© 2003 Southwestern/Thomson Learning All rights reserved. Tariffs, Quotas, and Other Interferences with Trade ●How Tariffs and Quotas Work ♦Both tariffs and quotas ■ price of imports ■ quantity of imports ♦Any restriction of imports that is accomplished by a quota normally can also be accomplished by a tariff ●How Tariffs and Quotas Work ♦Both tariffs and quotas ■ price of imports ■ quantity of imports ♦Any restriction of imports that is accomplished by a quota normally can also be accomplished by a tariff

Copyright© 2003 Southwestern/Thomson Learning All rights reserved. Tariffs, Quotas, and Other Interferences with Trade ●Tariffs versus Quotas ♦When imports are to be reduced, tariffs are generally preferable to quotas because: ■Tariffs generate income for the government ■Unlike quotas, tariffs offer no special benefits to inefficient exporters ●Tariffs versus Quotas ♦When imports are to be reduced, tariffs are generally preferable to quotas because: ■Tariffs generate income for the government ■Unlike quotas, tariffs offer no special benefits to inefficient exporters

Copyright© 2003 Southwestern/Thomson Learning All rights reserved. Can Cheap Imports Hurt a Country? ●Those who are hurt by cheap imports may fight to prevent their losses. ●Politics often leads to the adoption of protectionist measures that would be rejected on strictly economic terms. ●Those who are hurt by cheap imports may fight to prevent their losses. ●Politics often leads to the adoption of protectionist measures that would be rejected on strictly economic terms.
