Lesson 8 International Trade: Trade and welfare, tariffs and quotas

1 International Trade Who gains and who loses from free trade among countries? What are the arguments that people use to advocate trade restrictions? Countries do not trade individuals do! The determinants of international trade are the same as the determinants of any trade – specialization and trade bring mutual gains. Lesson 11

2 Comparative Advantage and differences in tastes
Why do people trade? Diversity among people and in nature. Different Tastes Different Abilities and Resources – comparative advantage Comparative Advantage (CA) plays a big role in determining the pattern of trade – internal and international CA refers to relative, rather than absolute, differences in costs (and prices) Example: The Secretary and the Attorney – it pays to specialize. The same principle applies in international trade. Activity/Value Typing Words per minute Legal Practice $ per hour Secretary 75 Attorney 90 300 Lesson 11

3 Viva la differance! It Pays to be different
Any difference is an opportunity for mutual gain The more different you are, the more gains to be had International Trade: small countries gain the most Adam Smith 18th century economist Described the way trade benefit all parties Increased productivity through specialization David Ricardo 19th century economist – c. 1830 First to recognize importance of comparative advantage Analyzed consequences for mutually beneficial trade Lesson 11

4 Equilibrium Without Trade
Assume: A country is isolated from rest of the world and produces steel. The market for steel consists of the buyers and sellers in the country. No one in the country is allowed to import or export steel. Lesson 11

5 Equilibrium without International Trade
Price of Steel Domestic demand Consumer surplus Domestic price adjusts to balance demand and supply. The sum of consumer and producer surplus measures the total benefits that buyers and sellers receive. Domestic supply Equilibrium price quantity Producer surplus Quantity of Steel Lesson 11

6 The World Price and Comparative Advantage
If the country decides to engage in international trade, will it be an importer or exporter of steel? The effects of free trade can be shown by comparing the domestic price of a good without trade and the world price of the good. The world price refers to the price that prevails in the world market for that good. If a country has a comparative advantage, then the domestic price will be below the world price, and the country will be an exporter of the good. If the country does not have a comparative advantage, then the domestic price will be higher than the world price, and the country will be an importer of the good. Lesson 11

7 How Free Trade Affects Welfare in an Exporting Country

Producer surplus before trade Domestic Demand Quantity of Steel Lesson 11

8 The Winners and Losers from Export Trade
The analysis of an exporting country yields two conclusions: Domestic producers of the good are better off, and domestic consumers of the good are worse off. Trade raises the economic well-being of the nation as a whole – gains outweigh losses These are partial and short term results. Lesson 11

9 The Gains and Losses of an Importing Country
International Trade in an Importing Country If the world price of steel is lower than the domestic price, the country will be an importer of steel when trade is permitted. Domestic consumers will want to buy steel at the lower world price. Domestic producers of steel will have to lower their output because the domestic price moves to the world price. Lesson 11

10 International Trade in an Importing Country
Price of Steel Domestic demand Consumer surplus before trade Domestic supply Domestic Supply Price before trade C B D A PD Price after trade World price PW Domestic quantity supplied Domestic quantity demanded Producer surplus before trade Imports Imports Domestic Demand Quantity of Steel Lesson 11

11 The Winners and Losers from Import Trade
The analysis of an importing country yields two conclusions: Domestic producers of the good are worse off, and domestic consumers of the good are better off. Trade raises the economic well-being of the nation as a whole in the sense that the gains of consumers exceed the losses of producers. These are partial and short term results. Lesson 11

12 The Effects of a Tariff A tariff is a tax on goods produced abroad and sold domestically. Tariffs raise the price of imported goods above the world price by the amount of the tariff. Lesson 11

13 Imposing a tariff Consumer surplus before tariff Producer surplus

14 The Effects of a Tariff A tariff reduces the quantity of imports and moves the domestic market closer to its equilibrium without trade. With a tariff, total surplus in the market decreases by an amount referred to as a deadweight loss. Lesson 11

15 The Effects of an Import Quota
An import quota is a limit on the quantity of a good that can be produced abroad and sold domestically. Lesson 11

16 Imposing an Import Quota
Price of Steel Domestic demand A Domestic Supply Equilibrium without trade Domestic supply + Import supply Quota B Price with quota Equilibrium with quota D Q S E' Q D C F World price Price without quota = E" Q S Q D G Imports with quota Quantity Imports without quota of Steel Lesson 11

17 The Effects of an Import Quota
Because the quota raises the domestic price above the world price, domestic buyers of the good are worse off, and domestic sellers of the good are better off. License holders are better off because they make a profit from buying at the world price and selling at the higher domestic price. With a quota, total surplus in the market decreases by an amount referred to as a deadweight loss. The quota can potentially cause an even larger deadweight loss, if a mechanism such as lobbying is employed to allocate the import licenses. Lesson 11

18 The Lessons for Trade Policy
If government sells import licenses for full value, revenue equals that of an equivalent tariff and the results of tariffs and quotas are identical. Both tariffs and import quotas . . . raise domestic prices. reduce the welfare of domestic consumers. increase the welfare of domestic producers. cause deadweight losses. Lesson 11

19 The Arguments for Restricting Trade
Jobs National Security Infant Industry Unfair Competition Protection-as-a-Bargaining Chip Lesson 11

20 Other Benefits of International Trade
Increased variety of goods Lower costs through economies of scale Increased competition enhanced flow of ideas, Lesson 11
