Budget constraints are drawn up for annual hours and net pay, typically composed of two linear segments: 'benefit-constrained', where extra work forfeits benefit and 'normal', where extra work is subject to the standard marginal tax rate. There are additional linear segments for those on upper...

The paper uses a general equilibrium model of regional labor markets, in which national and local factors interact to determine local wages and unemployment; when mobility between regions is obstructed by rent subsidies and controls, unemployment and wage differentials arise. Because...

The paper surveys recent analyses of rising unemployment in Europe based on the concept of the natural rate. It argues that there is a continuity of analysis from the classics through Keynes to these more recent approaches. Theories of efficiency wages, hysteresis, and insiders/outsiders are...

Development and convergence is explained as the transfer of technology embodied in machinery, to the manufacturing sector of those developing countries that institute the necessary property rights. The process is modelled within a Heckscher-Ohlin-Samuelson framework with capital mobility and...

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...
