This paper addresses the final steps to global free trade – what they might look like, what sort of political economy forces might drive them, and what the WTO might do to guide them. Two facts form the point of departure: 1) Regionalism is here to stay; world trade is regulated by a motley...

European economic integration fascinates and inspires for the way it brought peace to a continent torn by violent and long-standing rivalries. The lessons from Europe, however, cannot be applied directly as the degree of the European Union's supranationality is unthinkable elsewhere. This paper...

The introduction of the euro was the world's largest economic ‘experiment.' This experiment opens the door to a major advance in our understanding of how a  common currency affects economic activity. When it comes to the euro's trade effects the first contribution of this report is to...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

This paper examines the importance of buyer-supplier relationships, geography and the structure of the production network in firm performance. We develop a simple model where firms can outsource tasks and search for suppliers in different locations. Low search and outsourcing costs lead firms to...

This paper makes three contributions to the growing literature on culture and economics. Using answers to the World Values Survey for a sample of 79 countries over the 1989-2004 period, we first provide evidence of cultural homogenization between countries. Second, we provide a model of...

This paper examines the relationship between openness and within-country regional inequality across 28 countries over the period 1975-2005. In particular, it tests a) whether increases in trade lead to rising inequalities, b) whether these inequalities recede in time, and c) whether increases in...

We study patterns of FDI in a multi-country world economy. First, we present evidence for a broad sample of countries that firms direct FDI disproportionately to markets with income levels similar to their home market. Then we develop a model featuring non-homothetic preferences for quality and...

We propose a general model of monopolistic competition and derive a complete characterization of the market equilibrium based on an Arrow-Pratt measure of concavity of the utility, interpreted as the relative love for variety. When the relative love for variety increases with the consumption...
