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...

OECD labor markets have become more “polarized” with employment in the middle of the skill distribution falling relative to the top and (in recent years) also the bottom of the skill distribution. We test the hypothesis of Autor, Levy, and Murnane (2003) that this is partly due to...

Recent research has emphasized firm heterogeneity as a source of comparative advantage. Combining this approach with labor market frictions and worker heterogeneity provides a framework for studying the impact of trade on unemployment and inequality. This paper reviews this approach and reports...

We study a two-country two-sector model of international trade in which one sector produces homogeneous products while the other produces differentiated products. The differentiated-product industry has firm heterogeneity, monopolistic competition, search and matching in its labor market, and...

This paper models the causes of the 2008 financial crisis together with its manifestations, using a Multiple Indicator Multiple Cause (MIMIC) model. Our analysis is conducted on a cross-section of 85 countries; we focus on international linkages that may have allowed the crisis to spread across...

In the early stage of the 2008-2009 financial crisis, the conventional wisdom was that financial under-development of sub Saharan African economies may be a blessing in disguise because it insulates them from the direct effects of the crisis. This paper argues that this may also make African...
