We examine firm participation in global supply chains to help explain a puzzling decline in protectionist demands in the U.S. despite increased import competition and ongoing currency undervaluation. To explain firm responses to undervaluation, we rely on advances in the international trade...

Using a newly created microeconomic archive of U.S. imports at the tariff-line level for 1930-33, we construct industry-level tariff wedges incorporating the input-output structure of U.S. economy and the heterogenous role of imports across sectors of the economy. We use these wedges to show...

This paper reviews recent developments in international trade to evaluate several arguments concerning the merits of preferential trade agreements (PTAs) and their place in the world trade system. Taking a multilateralist perspective, it makes several points: First, despite the proliferation of...

This paper assesses the impacts of the WTO Government Procurement Agreement (GPA) on trade in both goods and services among members using a gravity model applied to a panel dataset covering 20 OECD countries over the period 1996-2008 for trade in goods and 1999-2008 for trade in services. The...

This paper builds a tractable partial equilibrium model in the spirit of Melitz (2003), which incorporates two dimensions of heterogeneity: firms specific productivity shocks and firm-market specific demand shocks. The structural parameters of interest are estimated using only cross-sectional...

What kind of tariff reform is likely to raise welfare in situations where tariff revenue is important? Uncertainty about specification and risk from imprecise parameter estimates of any particular specification reduce the credibility of simulation estimates. A promising alternative is to develop...

This paper presents a comprehensive but relatively brief historical survey of U.S. trade-policy over the last 75 years. It is aimed at individuals who are not already familiar with the concepts and terminology used in discussions of trade policy and the domestic and international institutional...

In this paper we explore the effect of trade policy on productivity and welfare in the now standard model of firm-level heterogeneity and product differentiation with monopolistic competition. To obtain sharp results, we restrict attention to an economy that takes as given the price of imports...

Small Think Regionalism focused on the Vinerian question: "Would a nation gain from joining a trade bloc?" Big Think Regionalism considers regionalism's systemic impact on the world trading system, focusing mainly on two questions: "Does spreading regionalism harm world welfare?" and "Does...

South African trade policy has exerted a major influence on the composition and aggregate growth of trade. In the Apartheid period, trade protection seriously impeded both exports and imports, and the economy depended on favorable global commodity price trends to avoid running into an external...
