Recent theoretical analysis suggests that a reduction in the cost of exporting increases the degree of assortative matching between workers and firms in export-oriented industries. Changes that reduce the cost of imports have an ambiguous impact on matching. We combine detailed Swedish matched...

The Heckscher-Ohlin-Vanek (HOV) theorem, which predicts that countries will export products that are made from factors in great supply, performs poorly. However, deviations from HOV follow pronounced patterns. Trade is missing relative to its HOV prediction. Also, rich countries appear scarce in...

Do scale economies help to explain international trade flows? Using a large database on output, trade flows, and factor endowments, we find that allowing for the presence of increasing returns to scale in production significantly increases our ability to predict international trade flows. In...

The Canada-U. S. Free Trade Agreement provides a unique window onto the effects of a reciprocal trade agreement on an industrialized economy (Canada). For industries that experienced the deepest Canadian tariff cuts, the contraction of low-productivity plants reduced employment by 12 percent...
