Three fundamental forces have shaped labor markets over the last 50 years: the secular increase in the returns to education, educational upgrading, and the integration of large numbers of women into the workforce. We modify the Katz and Murphy (1992) framework to predict the structure of the...

This paper presents a general equilibrium assignment model of workers to tasks with endogenous supply of skills. The model has 2 key features. First, skills are endogenous and multidimensional. Second, two types of assignment occur; workers self-select the type of skills to supply and firms...

We estimate the changes in US male labor market risk over the last three decades in a model of endogenous labor supply and job mobility. Across education groups permanent shocks to productivity have become more dispersed. Moreover, heterogeneity in pay across offered jobs has increased for...

This paper contrasts labour participation behaviour and wages of native and immigrant women. Since the impact of family structure on labor supply differs between natives and immigrants, we explicitly distinguish between part-time and full-time jobs. The choice of jobs is accounted for by an...

The incidence of Cesarean deliveries (CDs) has been on the rise. The procedure's cost and benefits are discussed controversially; in particular, since non-medically indicated cases seem widespread. We study the effect of CDs on subsequent fertility and maternal labor supply. Identification is...

Unreported labour by one worker in a firm increases the probability of detection for his fellow workers, not only for himself. The firm takes this external effect into account. As a consequence, unreported work becomes rationed by the firms demand, rather than determined by demand equal supply....
