On August 15, 1971, President Richard Nixon closed the gold window and imposed a 10 percent surcharge on all dutiable imports in an effort to force other countries to revalue their currencies against the dollar. The import surcharge was lifted four months later after the Smithsonian agreement...

This paper describes the updating of the NBER trade dataset, which now provides U.S. import and export values to the year 2001, disaggregated by Harmonized System (HS), Standard International Trade Classification (SITC), and the U.S. Standard Industrial Classification (SIC) categories. In...

The purpose of this paper is to theoretically assess, from a welfare perspective, the desirability of uniform import tariffs. Since the eruption of the debt crisis, many proposals for structural reforms in the developing countries have contemplated a trade liberalization process that would...

We propose and provide evidence for a new source of gains from trade: Firms invest in product differentiation to escape import competition. In the data and in the model, these investments are associated with increases in measured productivity, introduction of new goods, and shifts to...

In a standard multi-sector, heterogeneous-firm trade model the effect of tariffs on entry, especially in the presence of production linkages, can reverse the traditional positive optimal-tariff argument. We construct and employ a new, large, disaggregated tariff dataset and then apply a...

Free trade or preferential trade areas (PTAs) allow importers who belong to the area to export to each other while paying zero or preferential tariffs as long as Rules of Origin (ROOs) are met. Meeting them is costly not only in terms of production costs but also in terms of documentation costs....

This chapter investigates the non-market response of firms to international trade shocks increasing the level of competition in U.S. industries. Lobbying expenditures increase as a consequence of import changes related to the China shock. The effect on lobbying is not homogeneous across firms...

We study the growth of Chinese imports into the United States from autarky during 1950-1970 to about 15 percent of overall imports in 2008, taking advantage of the rich heterogeneity in trade policy and trade growth across products during this period. Central to our analysis is an accounting for...

We study unanticipated tariffs on imports of intermediate goods in a setting with firm-to-firm supply relationships. Firms that produce differentiated products conduct costly searches for potential input suppliers and negotiate bilateral prices with those that pass a reservation level of match...
