We show in a multi-sector, heterogeneous-firm trade model that the effect of tariffs on entry, especially in the presence of production linkages, can reverse the traditional positive optimal tariff argument. We then use a new tariff dataset, and apply it to a 189-country, 15-sector version of...

We analyze whether preferential trade agreements (PTAs) affect the incidence and pattern of antidumping (AD) filings. We estimate AD provisions in PTAs have decreased the incidence of intra-PTA AD cases by 33-55% and have increased the number of AD actions against non-PTA members by 10-30%. The...

How high were import tariffs when GATT participants began negotiations to reduce them in 1947? Establishing this starting point is key to determining how successful the GATT has been in bringing down trade barriers. If the average tariff level was about 40 percent, as commonly reported, the...

This paper reviews the history of bilateral trade negotiations between Taiwan and the U.S. The question posed at the outset is: does bilateralism enhance or jeopardize multilateralism? The U.S.-Taiwan experience seems to suggest a grossly negative answer. Bilateral negotiations for market...

We review a recent body of theoretical work that aims to put numbers on the consequences of globalization. A unifying theme of our survey is methodological. We rely on gravity models and demonstrate how they can be used for counterfactual analysis. We highlight how various economic...

This paper examines the microstructure of import markets and the division of the gains from trade among consumers, importers and exporters. When exporters and importers transact through anonymous markets, double marginalization and business stealing among competing importers lead to lower...

In a general equilibrium product-cycle model, lower trade barriers increase Southern purchasing power, which lifts long-run growth by increasing the profit from innovation. In the short run, factors of production must be reallocated inside firms, which lowers the opportunity cost of innovation,...
