Entrepreneurs who decide to enter an industry are faced with different levels of effective entry costs in different countries. These costs are heavily influenced by economic policy. What is not well understood is how international trade affects the government incentive to impact on entry costs,...

This paper explores the combined effects of reductions in trade frictions, tariffs, and firing costs on firm dynamics, job turnover, and wage distributions. It uses establishment-level data from Colombia to estimate an open economy dynamic model that links trade to job flows in a new way. The...

Popular sentiment toward immigration is often antagonistic, making the integration of migrants one of the most important yet daunting challenges facing societies in advanced economies. Can information campaigns decrease public opposition to immigration? This paper reports results from a...

In contrast to the very large literature on skill-biased technical change among workers, there is hardly any work on the importance of skills for the entrepreneurs who employ those workers, and in particular on their evolution over time. This paper proposes a simple theory of skill-biased change...

How and why does the firm size distribution differ across countries? Using two datasets covering more than 30 countries, this paper documents that several features of the firm size distribution are strongly associated with income per capita: the entrepreneurship rate and the fraction of small...

We use unique plant-level data to study the link between the local availability of services and the decision of manufacturing firms to source materials from abroad. To guide our empirical analysis we develop a monopolistic-competition model of the materials sourcing decisions of heterogeneous...

This paper proposes a new mechanism linking trade and wage inequality in developing countries - the quality-upgrading mechanism - and investigates its empirical implications in panel data on Mexican manufacturing plants. In a model with heterogeneous plants and quality-differentiated goods, only...

The robust empirical finding that exporting firms are systematically different from firms thatmerely serve domestic consumers has inspired the development of a new brand of tradetheory, the theory of heterogeneous firms and trade. The establishment of a canonical modeldue to Melitz (2003) has...

This paper provides a simple theory of geographical mobility which simultaneously explainspeople’s choice of residences in space and the location of industry. Residences are chosenon the basis of the utility which mobile households obtain across locations...

We construct a model of offshoring with externalities and firm heterogeneity. Due to thepresence of externalities, temporary shocks like the Y2K problem can have permanenteffects, i.e., they can permanently raise the extent of offshoring in an industry. Also, the initialadvantage of a country as...
