Section 1 The Gains From Trade

26.1 Absolute advantage: Occurs when one country can produce more of a good than another country.

Comparative advantage: Occurs when a country can produce a good at a lower opportunity cost than another country.

The United States has a comparative advantage in both soybean production (due to an abundance of fertile land) and commercial aircraft production (due to an abundance of technology and human capital).

26.2 Trade is a positive-sum game, which means that both countries in a trading relationship can gain compared to not trading.

Section 2 The Terms of Trade

26.3 The terms of trade determine the prices of imports and exports. When countries trade many commodities, the terms of trade are defined as the average price of exports divided by the average price of imports.

26.4 The Effect of Trade on Prices

Before trade, the prices charged for one good may be different in the two countries. The country with the lower price is likely to export the good; greater demand for that country’s good pushes prices higher. The country with the higher price is likely to import the good; lesser demand for that country’s good pushes prices lower. Market forces therefore push prices toward an equilibrium under free trade.

26.5 Tariffs are a tax on imports. They raise the domestic price of the good to the world price + tariff.

Winners: Domestic producers gain area A. Government gains area C in tariff revenues.

Losers: Domestic consumers lose areas A + B + C + D due to higher prices.

Net Loss: Areas B + D (deadweight loss from the tariff)

Quotas are an alternative to tariffs that directly restrict the quantity of imports. Quotas have a similar effect on prices as tariffs, except no tariff revenue is generated.

Historically, trade barriers have been high. In the 1930s, the Smoot-Hawley Act placed an average tax of 60% on most imported goods, arguably prolonging the Great Depression. Trade barriers have fallen since, and in the past three decades have fallen dramatically to nearly free trade with all countries.

Section 3 Arguments Against Free Trade

26.6 Many strong arguments against free trade exist. In each case, trade protection in the form of a tariff, quota, or subsidy is sought to protect the domestic industry.

Infant industry argument: States that a new industry requires protection to survive against established foreign competition. The problem is determining when these industries mature.

Antidumping argument: Dumping occurs when a foreign firm sells its goods below cost or at a price below what it charges in its domestic market.

Key industries argument: States that a country must be able to rely on its domestic industries for critical goods such as food, oil, steel, and defense equipment in times of conflict when trade might not be possible.

In the early 1980s, Harley-Davidson sought infant industry protection against competition from established lower-cost Japanese motorcycles, giving it time to retool its factories to become more competitive.

Protection Against Cheap Labor Argument: Argues that domestic workers need to be protected from cheap foreign labor. Most economists estimate that the benefits from lower-priced imports from free trade exceed the costs of lost employment. Further, increased trade generates jobs in export industries.

26.7 Environmental degradation argument: States that countries producing mass goods allow their environments to deteriorate. However, studies show that as countries develop and incomes grow, demand for environmental protection rises.

South Korea sustained environmental degradation during its economic development in the 1980s and 1990s. Today, it invests heavily in environmental protection and sustainable cities like Songdo outside the capital of Seoul.

26.8 Exploitation of foreign workers argument: Argues that trading with developing countries where wages are low and working conditions are deplorable exploits workers in these countries. But restricting trade would probably do more harm than good. Trade may be their only chance to grow and improve their standard of living.

Although working conditions in factories in developing countries look miserable, they often are better than working conditions before trade. In addition, trade increases demand for workers, which leads to higher wages.
