Country X Productivity Wheat -- 4 tons per hectare Bananas -- 4 tons per hectare Country Y Productivity Wheat -- 2 tons per hectare Bananas -- 60 tons per hectare Opportunity Cost per Ton 1 ton of bananas 1 ton of wheat Opportunity Cost per Ton 30 tons of bananas 1/30 ton of wheat Example 3A: Assume that Country X and Country Y do not trade with each other. Rather, each country produces both wheat and bananas. Each country uses half of its land (500 hectares) to produce wheat and half (500 hectares) to produce bananas. Country X will be able to produce 2,000 tons of wheat (500 hectares x 4 tons of wheat per hectare) and 2,000 tons of bananas (500 hectares x 4 tons of bananas per hectare). Country Y will be able to produce 1,000 tons of wheat (500 acres x 2 tons of wheat per hectare) and 30,000 tons of bananas (500 hectares x 60 tons of bananas per hectare). Total production for the two countries combined is 3,000 tons of wheat and 32,000 tons of bananas. Example 3B: Assume that Country X and Country Y produce and trade according to comparative advantage. Country X uses all 1,000 hectares of land to produce wheat, producing 4,000 tons of wheat (1,000 hectares x 4 tons of wheat per hectare). Country Y uses all 1,000 hectares to produce bananas, producing 60,000 tons of bananas (1,000 hectares x 60 tons of bananas per hectare). By producing according to comparative advantage, the output produced by the two countries combined has been increased, as detailed on the table: Tons of Production without Trade Tons of Production with Trade Wheat Bananas Wheat Bananas Country X 2,000 2,000 4,000 0 Country Y 1,000 30,000 0 60,000 Total 3,000 32,000 4,000 60,000 The examples above show that both countries can benefit from specialization and trade according to comparative advantage. The specialization according to comparative advantage causes resources to be allocated to their most productive uses. This allows for more production from the same amount of resources, and is a type of technological advance. But how do countries determine where their comparative advantage lies? Do the governments of Country X and Country Y need to carefully study opportunity cost and direct production accordingly? No. In a free market, profit-seeking will lead to production and trade according to comparative advantage. Profit-seeking producers in Country X will discover that producing wheat is profitable (they can produce at a lower opportunity cost than producers in Country Y) and that producing bananas is unprofitable. Thus, they will specialize in wheat production. Profit-seeking producers in Country Y will discover that producing bananas is profitable and that producing wheat is unprofitable. Thus, they will specialize in banana production. FOR REVIEW ONLY - NOT FOR DISTRIBUTION And what role will the governments of Country X and Country Y need to play to ensure that trade follows comparative advantage? Simply allow free trade. Don’t interfere with the competitive markets. In other words, do nothing. International Trade 16 - 2
Other Benefits of Free International Trade Along with the gain that arises from producing and trading according to comparative advantage, free international trade results in other benefits: 1. Free international trade extends markets, which allows nations to take more advantage of economies of scale and specialization of labor, and increases the potential returns to innovation. 2. Free international trade increases competition which compels domestic firms to increase their efficiency and to improve the quality of their products. 3. Free international trade speeds the flow of technological advances as firms are exposed to the improved production techniques of their foreign competitors and are motivated to adopt (or surpass) these improved production techniques. Nations that become isolated from other nations fall behind technologically. Example 4: Both China and India had relatively closed economies until recent decades. Both nations lagged behind technologically and had economies dominated by large and inefficient farming sectors. After the nations opened up to international trade in recent decades, they both made rapid progress technologically. See the appendix on International Trade and Economic Growth in China and India at the end of this chapter. 4. Free international trade gives consumers access to a greater variety of goods. 5. Free international trade improves international relations. Nations that are engaged in mutually beneficial trade have a strong incentive to avoid war (and lesser conflicts) that would disrupt the mutually beneficial trade. Trade Restrictions When nations engage in free international trade according to comparative advantage, the nations benefit overall. But not everyone within the nations may benefit personally (especially in the short run) from free international trade. Domestic producers who face increased competition from imports may suffer losses. Thus, domestic producers may seek governmentally imposed restrictions on trade (especially restrictions on imports). The two most commonly imposed trade restrictions are tariffs and quotas. Tariff – a tax on an imported good. Quota – a legal limit on the quantity of a good that may be imported. Both tariffs and quotas will reduce the supply of imports. This will allow domestic producers to sell a greater quantity at a higher price. Domestic producers will thus receive more producer’s surplus than before the trade restriction. This is the gain to domestic producers from trade restrictions. Producer’s surplus – the difference between the lowest price a seller is willing to accept and the price actually received. But while domestic producers gain from trade restrictions, domestic consumers lose. The domestic consumers will buy a lesser quantity at a higher price. Domestic consumers will thus receive less consumer’s surplus than before the trade restriction. This is the loss to domestic consumers from trade restrictions. FOR REVIEW ONLY - NOT FOR DISTRIBUTION Consumer’s surplus – the difference between the highest price a buyer is willing to pay and the price actually paid. 16 - 3 International Trade
