A salient feature of globalization in recent decades is the emergence of "global supply chains" in which different countries specialize in different stages of a sequential production process. In Arnaud Costinot, Jonathan Vogel and Su Wang (2011), CVW hereafter, we have developed a simple theory...

Capital equipment - such as computers and industrial machinery - embodies skill-biased technology, in the sense that it is complementary to skilled labor. Most countries import a large share of their capital equipment, and by doing so import skill-biased technology. In this paper we develop a...

The home-market effect, first hypothesized by Linder (1961) and later formalized by Krugman (1980), is the idea that countries with larger demand for some products at home tend to have larger sales of the same products abroad. In this paper, we develop a simple test of the home-market effect...

A large agronomic literature models the implications of climate change for a variety of crops and locations around the world. The goal of the present paper is to quantify the macro-level consequences of these micro-level shocks. Using an extremely rich micro-level dataset that contains...

When asked to name one proposition in the social sciences that is both true and non-trivial, Paul Samuelson famously replied: 'Ricardo's theory of comparative advantage'. Truth, however, in Samuelson's reply refers to the fact that Ricardo's theory of comparative advantage is mathematically...
