Though one of the pillars of the theory of international trade, the extreme predictions of the Ricardian model have made it unsuitable for empirical purposes. A seminal contribution of Eaton and Kortum (2002) is to demonstrate that random productivity shocks are sufficient to make the Ricardian...

Aggregate production functions are a standard feature of the trade theorist's toolbox. While this modeling device has generated some fundamental insights, it presents one obvious shortcoming: it necessarily ignores any effect that the distribution of factor endowments across agents may have on...

This paper analyzes the determinants of protectionism in a small open economy with search frictions. This this environment, jobs generate rents whose access depends on the level of trade protectionn. By raising the domestic price of a good, a government may attract more firms in a particular...

This paper proposes a simple theory of international trade with endogenous technological differences across countries. The core of our analysis lies in the determinants of the division of labor. We consider a world economy comprising two large countries, with a continuum of goods and one factor...

The WTO and the EU have chosen two different agreements on product standards. While the WTO's approach is primarily based on a "National Treatment" (NT) principle, the EU's approach crucially relies on a principle of "Mutual Recognition" (MR). This paper offers a first look at the comparative...

The theory of international trade has paid scant attention to market institutions. Neither neoclassical theory nor new trade models typically specify the process by which supply and demand meet. Yet in the real world, intermediaries play a central role in materializing the gains from exchange...

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...

The theory of comparative advantage is at the core of neoclassical trade theory. Yet we know little about its implications for how nations should conduct their trade policy. For example, should import sectors with weaker comparative advantage be protected more? Conversely, should export sectors...
