We develop a new model of multi-product firms which invest to improve the perceived quality of both their individual products and their brand. Because of flexible manufacturing, products closer to firms' core competence have lower costs, so firms produce more of them, and also have higher...

This paper examines the effect of Walmart's entry into Mexico on Mexican manufacturers of consumer goods. Guided by firm interviews that suggested substantial heterogeneity across firms in how they responded to Walmart's entry, we develop a dynamic industry model in which firms decide whether to...

This paper exploits the surge in Chinese exports from 1994 to 2004 to evaluate the effects of a competition shock from a low wage competitor for producers in an important middle-income country, Mexico. We find that this shock causes selection and reallocation at both firm and product levels and...

Most independent nations today were part of empires in 1945. Using bilateral trade data from 1948 to 2006, we examine the effect of independence on post-colonial trade. While there is little short-run effect on trade, after four decades trade with the metropole (colonizer) has contracted by...

Free trade in audio-visual services has faced opposition on the grounds that foreign media undermine domestic culture, and ultimately, global diversity. Using a long panel of French birth registries, we assess the media-culture link using name frequencies as a measure of tastes. Controlling for...

This paper develops a model of cross-border M&A activity that features firm-level productivity shocks and endogenous export activity. We show that foreign firms will be relatively more attracted to targets in the domestic country that had high productivity levels that induced them to invest in...

Global trade contracted quickly and severely during the global crisis. This paper uses a unique dataset of French firms to match export data to firm-level credit constraints and shows that most of the 2008–2009 trade collapse was due to the unprecedented demand shock and to product...
