There is a negative mean-dispersion relationship between the log of mean annual hours in an occupation and the standard deviation of log annual hours in that occupation. We document this pattern using data from the 1976-2011 Current Population Survey (CPS) and various Survey of Income and...

This paper studies the role of social security and tax and transfer programs for understanding cross-country differences in labor supply late in the life cycle. First, we use the Survey of Health, Ageing, and Retirement in Europe (SHARE) as well as the U.S. Health and Retirement Study (HRS) to...

There is a negative mean-dispersion relationship between the log of mean annual hours in an occupation and the standard deviation of log annual hours in that occupation. We document this pattern using data from the 1976-2011 Current Population Survey (CPS) and various Survey of Income and...

In this paper, we first use household survey data to documents facts on the heterogeneity and life-cycle dynamics of labor supply across many European countries and the U.S. We also document a substantial variation in the out-of-pocket medical expenses faced by individuals across countries. We...

This paper has three contributions. First, we document various facts about the labor supply decisions of men and women in the US over their life-cycle. For cohorts of male and female individuals in the PSID, we study the life-cycle profile of average hours worked, the variance of log hours, and...

We develop a quantitative theory of gender differences in labor market participation, hours worked, labor turnover, and human capital accumulation. In our theory, young females expect to face higher labor turnover and to work less hours than males because they allocate time to child rearing. As...

We build a heterogeneous life-cycle model which captures a large number of salient features of individual labor supply over the life cycle, by education, both along the intensive and extensive margins. The model provides an aggregation theory of individual labor supply, firmly grounded on...

There are substantial cross-country differences in labor supply late in the life cycle (age 50+). A theory of labor supply and retirement decisions is developed to quantitatively assess the role of social security, disability insurance, and taxation for understanding differences in labor supply...

We build a heterogeneous life-cycle model which captures a large number of salient features of individual labor supply, by education, over the life cycle. The model provides an aggregation theory of individual labor supply, firmly grounded on micro evidence, and is used to study the aggregate...

An important feature of the U.S. labor market is that, even after controlling for measurable differences in education and experience, the average wage of women with children is 89 percent of the average wage of women without children. This "family gap" in wages accounts for almost half the...
