We use a simple theory of a system of cities to decompose the determinants of the city size distribution into three main components: efficiency, amenities, and frictions. Higher efficiency and better amenities lead to larger cities but also to greater frictions through congestion and other...

This paper explores the causes and consequences of regional taste differences. I introduce habit formation into a standard general equilibrium model. Household tastes evolve over time to favor foods consumed as a child. Thus, locally abundant foods are preferred in every region, as they were...

We analyze the effect of rising Chinese import competition between 1990 and 2007 on US local labor markets, exploiting cross- market variation in import exposure stemming from initial differences in industry specialization and instrumenting for US imports using changes in Chinese imports by...

We develop a stylized model of frictional local labor markets with the goal of studying the efficiency of unemployment differences across areas. The model adapts the widely used Diamond-Mortensen-Pissarides framework to a local labor market setting with a competitive housing market. The result...

Why do workers earn so much more in the United States than in India? This study compares the earnings of workers in the two countries in a unique setting. The product is perfectly tradable (software), technology differences are nil (they are members of the same work team), and the workers are...

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 elimination of externally imposed export quotas. Both the surge in export volume and the decline in export...

This paper explores the links between exports, export destinations, and skill utilization. We identify two mechanisms behind these links: differences across destinations in quality valuation and in exporting required services, activities that are intensive in skilled labor. Depending on the...
