I estimate the relative magnitudes of worker switching costs and how much the employer switching of experienced engineers responds to outside wage offers. Institutional features imply that voluntary turnover dominates switching in the market for Swedish engineers from 1970--1990. I use data on...

Four million blacks left the South from 1940 to 1970, doubling the northern black workforce. I exploit variation in migrant flows within skill groups over time to estimate the elasticity of substitution by race. I then use this estimate to calculate counterfactual rates of wage growth. I find...

It is often argued that informal labor markets in developing countries promote growth by reducing the impact of regulation. On the other hand informality may reduce the amount of social protection offered to workers. We extend the wage-posting framework of Burdett and Mortensen (1998) to allow...

This paper considers a dynamic, non-steady state environment in which wage dispersion exists and evolves in response to shocks. Workers do not observe firm productivity and firms do not commit to future wages, but there is on-the-job search for higher paying jobs. The model allows for firm...

Since the early 1980s, wage dispersion and the ratio of skilled to unskilled employment have increased significantly in several industrial countries. A number of economists have attributed these trends to skill-biased technical progress. This paper studies the wage and employment effects of...

We study the logic of Peronist interventionist polices and the beliefs that support them. Instead of a comprehensive approach, we focus on three elements. First, we study beliefs and values about the economic system present in Peron's speeches during the period 1943-55. Second, we study survey...
