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...

We use the structure of the Melitz (2003) model to compare the cost of living and welfare across countries, while incorporating product variety measured by the count of barcodes or firms. For 47 countries, we compare welfare relative to the United States to conventional measures of real...

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...
