What insights can be gained from bringing the theory of the firm to the global economy? I discuss several new features of the world economy that can be explained by incorporating the theory of the firm into the theory of international trade. Among the new features I discuss are the move to...

This paper quantifies the effect of the government-controlled appreciation of the Chinese renminbi (RMB) vis-à-vis the USD from 2005 to 2008 on the prices charged by US producers. As the RMB during that time was pegged to a basket of currencies, the empirical strategy must account for the fact...

Mexico experienced a tremendous expansion of its export-processing maquila sector during the 1990s. At the same time, a large proportion of its labor force remains employed in the informal sector. Since one of the main objectives of the maquiladora program was to increase formal employment, we...

In this paper, we merge the heterogenous firm trade model of Melitz (2003) with the Ricardian model of Dornbusch, Fisher and Samuelson (DFS 1977) to explain how the pattern of international specialization and trade is determined by the interaction of comparative advantage, economies of scale,...

This paper provides a direct test of how fixed export costs and productivity jointly determine firm-level export behavior. Using Chilean data, we construct indices of fixed export costs for each industry-region-year triplet and match them to domestic firms. Our empirical results show that firms...

This paper provides first firm-level evidence of the links between income inequality and the patterns of trade and export prices. We identify a theoretical mechanism behind these links, which suggests that a more unequal income distribution leads to higher average prices. We test the theory...

Why is it that exporter productivity premia (EPP) differ so widely in size? We take this question to the theory and to the data. We derive the sectoral EPP in a standard heterogeneous firms trade model and apply the insights from the model to 13 years of data for all Danish manufacturing firms....

This paper uses micro-data from the World Bank Investment Climate Surveys 2002-2006 to investigate how foreign ownership and access to external finance affect the likelihood of manufacturers in emerging markets to export and/or import. Applying propensity score matching to control for...

This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions. The model shows that investments in abatements are positively related to firm productivity and firm exports. Emission...

Helpman, Melitz and Rubinstein (2008) derive gravity equations to estimate effects of trade barriers on the intensive and extensive margins of trade. They exploit the frequency of zeros in aggregate bilateral trade data to identify effects on the extensive margin and to obtain controls for firm...
