Recent research in international trade emphasizes the importance of firms' extensive margins for understanding overall patterns of trade as well as how firms respond to specific events such as trade liberalization. In this paper, we use detailed US trade statistics to provide a broad overview of...

This paper examines the determinants of intra-firm trade in US imports using detailed country-product data. We create a new measure of product contractibility based on the degree of intermediation in international trade for the product. We find important roles for the interaction of country and...

This paper reviews the empirical evidence on firm heterogeneity in international trade. A first wave of empirical findings from micro data on plants and firms proposed challenges for existing models of international trade and inspired the development of new theories emphasizing firm...

Exporting is often touted as a way to increase economic growth. This paper examines whether exporting has played any role in increasing productivity growth in U.S. manufacturing. Contemporaneous levels of exports and productivity are indeed positively correlated across manufacturing industries....

Standard models of international trade devote little attention to firms. Yet of the 5.5 million firms operating in the United States in 2000, just 4 percent engaged in exporting, and the top 10 percent of these exporting firms accounted for 96 percent of U.S. exports. Since the mid 1990s, a...

Do New York and Nashville face the same pressures from increased trade? This paper considers the role of international trade in shaping the product mix and relative wages for regions within the US. Using the predictions from a Heckscher-Ohlin trade model, we ask whether all the regions in the US...

We reconcile international trade theory with findings of enormous plant-level heterogeneity in exporting and productivity. Our model extends basic Ricardian theory to accommodate many countries, geographic barriers, and imperfect competition. Fitting the model to bilateral trade among the United...

Exporting is often touted as a way to increase economic growth. This paper examines whether exporting has played any role in increasing productivity growth in U.S. manufacturing. Contemporaneous levels of exports and productivity are indeed positively correlated across manufacturing industries....

This paper uses data on inequality within U.S. states to test hypotheses about the sources of rising wage inequality during the 1970s and 1980s. State labor markets are found to respond to local demand shocks in the short and medium run and to national (industry) demand shocks only after long...

U.S. exports grew at a rate of 8.2% per year from 1987-1994, far faster than the economy as a whole or even the manufacturing sector. This paper examines the source of this export boom and argues that the boom itself has been less remarkable for the rate of growth of exports than for the...
