We examine the relationship between import competition from low wage countries and the reallocation of US manufacturing from 1977 to 1997. Both employment and output growth are slower for plants that face higher levels of low wage import competition in their industry. As a result, US...

This paper examines the response of industries and firms to changes in trade costs. Several new firm-level models of international trade with heterogeneous firms predict that industry productivity will rise as trade costs fall due to the reallocation of activity across plants within an industry....

This paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by U.S. manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than...

This paper develops a general test of factor price equalization that is robust to unobserved regional productivity differences, unobserved region-industry factor quality differences and variation in production technology across industries. We test relative factor price equalization across...

Previous research has uncovered precious little support for Heckscher-Ohlin trade theory. This paper demonstrates that those efforts focus on an overly restrictive version of the model. Indeed, strong evidence that output is a function of endowments can be found if we recognize that countries...

Do rich and poor countries compete by exporting the same mix of goods to the US? Using highly disaggregate trade flow data ? which breaks US imports into thousands rather than tens of goods ? this paper documents two significant trends. First, the portion of US imports originating in either rich...
