National welfare of a small country is highest with free trade. With restricted trade, consumers pay higher prices and consume too little while domestic firms produce too much.

All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg The Cases for Free Trade •Free trade allows firms or industry to take advantage of economies of scale. –In the case of external economies of scale, protected markets inhibit the concentration of industries. –In the case of internal economies of scale, protected markets lead to the ineficient scale of production for firms. •Free trade increases competition and provides opportunities for innovation (dynamic benefits). –By providing entrepreneurs with an incentive to seek new ways to export or compete with imports, free trade offers more opportunities for learning and innovation. • Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg The Cases for Free Trade •Free trade avoids the loss of resources through rent seeking. –Spend time and other resources seeking quota rights and the profit that they will earn. •The political argument for free trade says that free trade is the best feasible political policy, even though there may be better policies in principle. –Any policy that deviates from free trade would be quickly manipulated by political groups, leading to decreased national welfare. • Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Case Study: The Gains from 1992 •In 1987, the nations of EC agreed on Single European Act, with the intention to create a truly unified European market. The Act went into effect in 1992. –The European Community was already a custom union. There were no tariffs or import quotas on intra-European trade. •What would be the gains from creating this unified single market? –The elimination of red-tape barriers (bureaucratic barriers) –Politically difficult negotiations, most problems involved food. –According to some economists, it should lead to less segmented markets and more efficient production, as the firms can economize on the scale of production.

All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg The Cases against Free Trade •For a “large” country, a tariff lowers the price of imports in world markets and generates a terms of trade gain. –This benefit may exceed the losses caused by distortions in production and consumption. •A small tariff will lead to an increase in national welfare for a large country. –But at some tariff rate, the national welfare will begin to decrease as the economic efficiency loss exceeds the terms of trade gain.

All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Fig. 10-2: The Optimum Tariff fig10_02.gif A tariff rate that completely prohibits imports leaves a country worse off. For a large country, there is an optimum tariff tO that maximizes national welfare. Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Counter-Argument •For large countries like the U.S., an import tariff could improve national welfare at the expense of other countries. •But this argument ignores the likelihood that other countries may retaliate against large countries by enacting their own trade restrictions. Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg The Cases against Free Trade •Another argument against free trade is that domestic market failures may exist that cause free trade to be a suboptimal policy. –The economic efficiency loss calculations using consumer and producer surplus assume that markets function well. •The domestic market failure argument against free trade is an example of the theory of the second best. –Government intervention that distorts market incentives in one market may increase national welfare by offsetting the consequences of market failures elsewhere. –If the best policy, fixing the market failures, is not feasible, then government intervention in another market may be the “second-best” way of fixing the problem. • • Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg The Cases against Free Trade •Types of market failures include –Persistently high underemployment of workers –Persistently high underutilization of structures, equipment, and other forms of capital –Property rights not well defined or well enforced –technological benefits for society discovered through private production, but from which private firms cannot fully profit –environmental costs for society caused by private production, but for which private firms do not fully pay Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Fig. 10-3: The Domestic Market Failure Argument for a Tariff fig10_03.gif •The marginal social benefit represents the additional benefit to society from private production which is not covered by the producer surplus. •Because of that may be calculations of economic efficiency loss misleading – it does not take into account the area c. •It’s possible that when a tariff increases domestic production, the benefit to domestic society will increase due to a market failure. Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Counter-Arguments •Economists supporting free trade argue that domestic market failures should be corrected by a “first-best” policy: a domestic policy aimed directly at the source of the problem. –If persistently high underemployment of labor is a problem, then the cost of labor or production of labor-intensive products could be subsidized by the government. –This policy could avoid economic efficiency losses due to a tariff. Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Counter-Arguments •Unclear when and to what degree a market failure exists in the real world. •Government policies to address market failures are likely to be manipulated by politically powerful groups. •Due to distorting the incentives of producers and consumers, trade policy may have unintended consequences that make a situation worse, not better. • Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Political Models of Trade Policy •How is trade policy determined? •Models of governments maximizing political success rather than national welfare: 1.Median voter theorem 2.Collective action 3.A model that combines aspects of collective action and the median voter theorem Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Median Voter •The median voter theorem predicts that political parties pick their policies to court the voter in the middle of the ideological spectrum (i.e., the median voter). •Suppose the level of a tariff rate is the policy issue. –Line up all the voters according to the tariff rate they prefer, starting with those who favor the lowest rate. •Assumptions of the model: –There are two competing political parties. The objective of each party is to get elected by majority vote. •What policies will the parties promise to follow? –Both parties will offer the same tariff policy to court the median voter (the voter in the middle of the spectrum) in order to capture the most votes. • Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Fig. 10-4: Political Competition fig10_04.gif Voters are lined up in order of the tariff rate they prefer. If one party proposes a high tariff of tA, the other party can win over most of the voters by offering a somewhat lower tariff tB. This political competition drives both parties to propose tariffs close to tM, the tariff preferred by the median voter. Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Median Voter •Thus, the median voter theorem implies that a two-party democracy should enact trade policy based on how many voters it pleases. –A policy that inflicts large losses on a few people (import-competing producers) but benefits a large number of people (consumers) should be chosen. •But trade policy doesn’t follow this prediction. Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Collective Action •Political activity is often described as a collective action problem: –While consumers as a group have an incentive to advocate free trade, each individual consumer has no incentive because his benefit is not large compared to the cost and time required to advocate free trade. –Policies that impose large losses for society as a whole but small losses on each individual may therefore not face strong opposition. •However, for groups who suffer large losses from free trade, each individual in that group has a strong incentive to advocate the policy he desires. –In this case, the cost and time required to advocate restricted trade is small compared to the cost of unemployment. • Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg A Model of Trade Policy •While politicians may win elections partly because they advocate popular policies as implied by the median voter theorem, they also require funds to run campaigns. •These funds may especially come from groups who do not have a collective action problem and are willing to advocate a special interest policy. •Models of trade restrictions try to measure the trade-off between the reduction in welfare of constituents as a whole and the increase in campaign contributions from special interests.

Since 1944, much of the reduction in tariffs and other trade restrictions has come about through international negotiations. Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg International Negotiations of Trade Policy •Multilateral negotiations mobilize exporters to support free trade if they believe export markets will expand. –This support would be lacking in a unilateral push for free trade. The multilateral approach counteracts the support for restricted trade by import-competing groups. •Multilateral negotiations also help avoid a trade war between countries, where each country enacts trade restrictions. –A trade war could result if each country has an incentive to adopt protection, regardless of what other countries do. –All countries could enact trade restrictions, even if it is in the interest of all countries to have free trade.

All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg International Trade Agreements: A Brief History •In 1930, the United States passed a remarkably irresponsible tariff law, the Smoot-Hawley Act. –Tariff rates rose steeply, other countries retaliated and the U.S. trade fell sharply. –It was a response of the U.S. government to recession. It helped to deepen the Great Depression and to spread it worldwide. •Initial attempts to reduce tariff rates were undertaken through bilateral trade negotiations: –U.S. offered to lower tariffs on some imports if another country would lower its tariffs on some U.S. exports. –Bilateral negotiations, however, do not take full advantage of international coordination. Benefits can “spill over” to countries that have not made any concessions. • – Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg International Trade Agreements: A Brief History •In 1947, a group of 23 countries began trade negotiations under a provisional set of rules that became known as the General Agreement on Tariffs and Trade, or GATT. •In 1995, the World Trade Organization, or WTO, was established as a formal organization for implementing multilateral trade negotiations (and policing them). – Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg World Trade Organization •WTO negotiations address trade restrictions in 3 ways: 1.Reducing tariffs through multilateral negotiations. –Kennedy Round, Tokyo Round, Uruguay Round, Doha Round 2.Binding tariffs: a tariff is “bound” by having the imposing country agree not to raise it in the future. 3.Eliminating nontariff barriers: quotas and export subsidies are changed to tariffs because the costs of tariff protection are more apparent and easier to negotiate. –Subsidies for agricultural exports are an exception. –Exceptions are also allowed for “market disruptions” caused by a surge in imports. Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg World Trade Organization •The WTO is based on a number of agreements: –General Agreement on Tariffs and Trade: covers trade in goods. –General Agreement on Tariffs and Services: covers trade in services (insurance, consulting, legal services, banking). –Agreement on Trade-Related Aspects of Intellectual Property: covers international property rights (patents and copyrights). •The dispute settlement procedure: a formal procedure where countries in a trade dispute can bring their case to a panel of WTO experts to rule upon. –The panel decides whether member counties are breaking their agreements. A country that refuses to adhere to the panel’s decision may be punished by the WTO allowing other countries to impose trade restrictions on its exports. • Copyright ©2015 Pearson Education, Inc.

Rather than gaining tariff revenue from inexpensive imports from world markets, a country may import expensive products from member countries but not gain any tariff revenue. Copyright ©2015 Pearson Education, Inc. All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Preferential Trading Agreements •Preferential trading agreements increase national welfare when new trade is created, but not when existing trade from the outside world is diverted to trade with member countries. •Trade creation –occurs when high-cost domestic production is replaced by low-cost imports from other members. •Trade diversion –occurs when low-cost imports from nonmembers are diverted to high-cost imports from member nations.

All rights reserved. 10-‹#› cornerkrugman_10e_cover.jpg Trade Diversion in South America •In 1991, Argentina, Brazil, Paraguay, and Uruguay formed a free trade area: Mercosur. –Within four years, the value of trade among the nations tripled. –Political interpretation – a major success. •From the major part it was however trade diversion rather than trade creation –Consumers in the member countries were being induced to buy expensively produced goods from their neighbours instead of cheaper but heavily tariffed goods from other countries. –Because of Mercosur, Brazil’s highly protected and somewhat inefficient auto industry could dominate the market in Argentina and displace cheaper but heavily tariffed imported cars from elsewhere.
