We study the optimal design of a social security system when individuals differ in health status and occupation. The health status is private information but is imperfectly correlated with occupation: individuals in harsh occupations have a higher probability of being in poor health. We explore...

This paper introduces a static structural model of hours of market labor supply, time spent on child care and other domestic work, and bought in child care for married or cohabiting mothers with pre-school age children. The father's behavior is taken as given. The main goal is to analyze the...
