Wage Inequality and Segregation by Skill

Abstract

Evidence from the United States, Britain, and France suggests that recent growth in wage inequality has been accompanied by greater segregation of high- and low-skill workers into separate firms. A model in which workers of different skill-levels are imperfect substitutes can simultaneously account for these increases in segregation and inequality either through technological change, or, more parsimoniously, through observed changes in the skill-distribution.
