We assess the role of global value chains in transmitting global integration shocks to aggregate trade, as well as distributional outcomes. We develop a multi-country general equilibrium trade model that features multi-stage production, with different stages having different productivities and...

Growth in international trade and globalization has been correlated in nearly all countries with a worsening of the less skilled labor situation relative to the skilled. In this empirical paper, I show that an important component of recent globalization in France has been a huge growth in...

This paper investigates some alternative definitions of labor for productivity and demand analysis. The paper is organized as follows: Section II considers the organization of work activities in a simple fixed coefficient technology in the presence of comparative advantage among various classes...

The effects of exchange rate fluctuations across the population is an important issue for increasingly globalized economies. Previous studies using industry aggregate data have found differences across industries in the labor market implications of exchange rates, reporting that industry wages...

This paper offers a model where firms decide what types of jobs to create and then search for suitable workers. When there are few skilled workers and the productivity gap between the skilled and the unskilled is small, firms create a single type of job and recruit all workers. An increase in...

In this paper, I develop a model to analyze how skill premia differ over time and across countries, and use this model to study the impact of international trade on wage inequality. Skill premia are determined by technology and the relative supply of skills. An increase in the relative supply of...

I show that a CES production-function-based approach with skill differentiation and integrated national labor markets has predictions for the employment effect of immigrants at the local level. The model predicts that if I look at the employment (rather than wage) response by skill to...

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 information...

Low-skill workers are comparatively immobile: when labor demand slumps in a city, low-skill workers are disproportionately likely to remain to face declining wages and employment. This paper estimates the extent to which (falling) housing prices and (rising) social transfers can account for this...

We offer an integrated explanation and empirical analysis of the polarization of U.S. employment and wages between 1980 and 2005, and the concurrent growth of low skill service occupations. We attribute polarization to the interaction between consumer preferences, which favor variety over...
