Foreign trade zones: growth amid controversy
Working Paper
How much of South Korea's growth miracle can be explained by trade policy?
South Korea's growth miracle has been well documented. A large set of institutional and policy reforms in the early 1960s is thought to have contributed to the country's extraordinary performance. In this paper, the authors assess the importance of one key set of policies, the trade policy reforms in Korea, as well as the concurrent GATT tariff reductions. They develop a model of neoclassical growth and trade that highlights two forces by which lower trade barriers can lead to increased per worker GDP: comparative advantage and specialization, and capital accumulation. The authors calibrate ...

The agreement on subsidies and countervailing measures: tying one's hands through the WTO
Why would governments agree to restrict their own discretion in setting domestic policies as part of a trade agreement? This paper examines the welfare consequences of the GATT's Agreement on Subsidies and Countervailing Measures (SCM). If countries which join a trade agreement are given free reign over the use of domestic production subsidies, then after negotiating tariff reductions, governments could undermine the agreement by introducing production subsidies to import-competing producers that effectively act as trade barriers. The SCM restricts the use of domestic subsidies by countries ...

Tariff risk and international borrowing with incomplete asset markets.
When residents of two countries have access to complete contingent claims markets, the welfare effects of changes in tariffs are opposite to those found in static trade theory. This paper demonstrates that a much simpler asset market structure can be sufficient to generate such a result. In the context of a two period model with asset trade restricted to simple bonds, I decompose wealth and substitution effects that underlying the impact oftariff changes on consumption and the current account. Use of this relatively simple model helps to provide intuitive insight and facilitates the use of an ...

Income taxes as reciprocal tariffs
This article shows the equivalence between tariffs on international trade and income taxation. Traditionally, income taxes have been seen as lowering society's output through the household's labor-leisure trade-off. Income taxes also reduce the degree to which individuals specialize in market activity, which is similar to the way countries respond to tariffs in international trade. Income taxes discourage individuals from specializing in activities that reflect their comparative advantage. In so doing, income taxes may have their most distorting effects, not by encouraging individuals to ...

Classical and neoclassical roots of the theory of optimum tariffs
Despite their image as free traders, six leading British classical and neoclassical economists formulated a valid theoretical argument for tariffs. They showed that a suitably small tariff could, under certain conditions, benefit the levying country by improving its terms of trade. They also stressed the insuperable practical difficulties of implementing such optimum tariffs. These difficulties plus the likelihood of foreign retaliation convinced them that free trade was the best policy after all.

Multilateralism and the endogenous formation of PTAs
This paper examines the interaction between preferential trade agreements (PTAs) and multilateral tariff reduction in a model of imperfect competition. A growing literature finds that the formation of PTAs alters the incentives for and the sustainability of multilateral tariff reduction. We show that the causation is not one-sided -- multilateral tariff reduction also affects the formation of PTAs. Specifically, tariff reduction enhances the incentives to form a PTA and increases the likelihood that it is self-enforcing. Thus, each round of multilateral tariff reduction should lead to a new ...

The asymmetric effects of tariffs on intra-firm trade and offshoring decisions
This paper studies the effects of tariffs on intra-firm trade. Building on the Antrs and Helpman (2004) North-South theoretical framework, I show that higher Northern tariffs reduce the incentives for outsourcing and offshoring, while higher Southern tariffs have the opposite effects. I also show that increased offshoring and outsourcing imply an increase in the ratio of Northern intra-firm imports to total imports, which is an empirically testable prediction. Using a highly disaggregated dataset of U.S. (the North) imports and relevant tariffs, I find robust evidence to support the model's ...
