This paper presents a theory of trade agreements where "politics" play an central role. This stands in contrast with the standard theory, where even politically-motivated governments sign trade agreements only to deal with terms-of-trade externalities. We develop a model where governments may be...

In this paper we reconsider a key empirical prediction generated by an important class of political-economy models of trade policy, namely that trade protection should be higher in sectors characterized by lower import penetration (we call this the little support for this prediction. In this...

Building on Eaton and Kortum's (2002) model of Ricardian trade, Alvarez and Lucas (2005) calculate that a small country representing 1% of the world's GDP experiences a gain of 41% as it goes from autarky to frictionless trade with the rest of the world. But the gains from openness, which...

Is the variation in bilateral trade flows across countries primarily due to differences in the number of exporting firms (the extensive margin) or in the average size of an exporter (the intensive margin)? And how does this affect the estimation and quantitative implications of the Melitz (2003)...

Export Pioneers in Latin America analyzes a series of case studies of successful new export activities throughout the region to learn how pioneers jump-start a virtuous process leading to economic transformation. The cases of blueberries in Argentina, avocados in Mexico, and aircraft in Brazil...

The Melitz model highlights the importance of the extensive margin (the number of firms exporting) for trade flows. Using the World Bank's Exporter Dynamics Database (EDD) featuring firm-level exports from 50 countries, we find that around 50 percent of variation in exports is along the...

Falling costs of coordination and communication have allowed firms in rich countries to fragment their production process and offshore an increasing share of the value chain to low-wage countries. Popular discussions about the aggregate impact of this phenomenon on rich countries have stressed...

The literature on the correlation between exports and economic development runs deep into the history of economic thought and permeates policy debates. This paper studies the microeconomic structure of export growth in Costa Rica, with special emphasis on the extensive margin of trade,...

There is a common perception that low productivity or low growth is due to what can be called an quot;innovation shortfallquot;, usually identified as a low rate of investment in research and development (Ramp;D) when compared with some high innovation countries. The usual reaction to this...
