We conduct a randomized control trial that generates exogenous variation in the access to foreign markets for rug producers in Egypt. Combined with detailed survey data, we causally identify the impact of exporting on firm performance. Treatment firms report 15-25 percent higher profits and...

Researchers typically invoke theoretical assumptions to estimate mark-ups. Instead, we directly obtain mark-ups by surveying Pakistani soccer-ball producers. We document six facts: (1) Mark-ups are more dispersed than costs; (2) Mark-ups and costs increase with firm size; (3) The mark-up...

We study the evolution of market-oriented policies over time and across countries. We consider a model in which own and neighbors' past experiences influence policy choices through their effect on policymakers' beliefs. We estimate the model using a large panel of countries and find that it fits...

Anthropologists have long documented substantial and persistent differences across social groups in the preferences and taboos for particular foods. One natural question to ask is whether such food cultures matter in an economic sense. In particular, can culture constrain caloric intake and...

This paper examines how prices, markups and marginal costs respond to trade liberalization. We develop a framework to estimate markups from production data with multi-product firms. This approach does not require assumptions on the market structure or demand curves faced by firms, nor...

If trade barriers are managed by inefficient institutions, trade liberalization can lead to greater-than-expected gains. We examine Chinese textile and clothing exports before and after the removal of externally imposed quotas. Both the surge in export volumes and the decline in prices after the...

How does competition affect innovation? We address this question by using a novel approach to measure quality - an important component of innovation - using highly disaggregated product data for a large set of countries. Constructing an internationally comparable measure of quality enables us to...

Recent theoretical work predicts that an important margin of adjustment to deregulation or trade reforms is the reallocation of output within firms through changes in their product mix. Empirical work has accordingly shifted its focus towards multi-product firms and their product mix decisions....
