Using data on U.S. intra-firm and arm's-length imports for 5705 products imported from 220 countries, we examine the determinants of the share of U.S. imports that are intra-firm. We examine two predictions that arise from Antràs (2003), Antràs and Helpman (2008) and Antràs and Helpman...

We show that the "skill bias" of a country's tariff structure is positively correlated with long-term per capita GDP growth. Testing for causal mechanisms, we find evidence consistent with the existence of real benefits from tariffs focused in skill-intensive industries. However, this only...

It has long been recognized that a country's tariffs are the endogenous outcome of a rent-seeking game whose equilibrium reflects national institutions. Thus, the structure of tariffs across industries provides insights into how institutions, as reflected in tariff policies, affect long-term...

Domestic institutions can have profound effects on international trade. This chapter reviews the theoretical and empirical underpinnings of this insight. Particular attention is paid to contracting institutions and to comparative advantage, where the bulk of the research has been concentrated....

Economics lacks a good theory of the pricing and output decisions of a monopolist which does not know its demand--we inevitably assume that the monopolist knows much more about demand conditions than is reasonable. I present a model in which demand information is generated endogenously. When...
