● 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.

● Mutual Gains from Trade♦ When trade is voluntary:
■Both sides must expect to gain from it■Otherwise, they would not trade

● Why international trade is studied separately:♦ Countries are governed by separate
governments♦ International trade involves the exchange of
national currencies♦ Labor and capital are less mobile
internationally than they typically are within a country

● 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.

● 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.

Comparative Advantage: “Cheap Foreign Labor”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.

Supply, Demand, and Pricing in World TradeSupply, 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 TradeTariffs, 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

♦ Protect particular industries
♦ National defense and other non-economic reasons
