In this paper I use a large multi-country data set to analyze the determinants of abrupt and large "current account reversals." The results from a variance-component probit model indicate that the probability of experiencing a major current account reversal is positively affected by larger...

We develop an empirical framework to assess the importance of trade and technical change on the wages of production and nonproduction workers. Trade is measured by the foreign outsourcing of intermediate inputs, while technical change is measured by the shift towards high-technology capital such...

This paper explores the geographic overlap of trade and technology shocks across local labor markets in the United States. Regional exposure to technological change, as measured by specialization in routine task-intensive production and clerical occupations, is largely uncorrelated with regional...

In this paper, we develop a simple empirical method to test two alternative versions of the Melitz (2003) model, one with global fixed export costs and one with bilateral fixed export costs. With global costs, import sales per product variety (relative to domestic sales per variety) are...

In this paper I analyze the relationship between the U.S. dollar and the U.S. current account. I deal with issues of sustainability, and I discuss the mechanics of current account adjustment. The analysis presented in this paper differs from other work in several respects: First, I emphasis the...

Multinational firms (MNEs) accounted for 42 percent of US manufacturing employment, 87 percent of US imports, and 84 of US exports in 2007. Despite their disproportionate share of global trade, MNEs' input sourcing and final-good production decisions are often studied separately. Using newly...

Import tariffs tend to be higher for final goods than for inputs, a phenomenon commonly referred to as tariff escalation. Yet neoclassical trade theory - and modern Ricardian trade models, in particular - predict that welfare-maximizing tariffs are uniform across sectors. We show that tariff...
