Medicaid was primarily designed to protect and insure the poor against medical shocks. Yet, poorer people tend to live shorter lifespans and incur lower medical expenses before death than richer people. Taking these and other important dimensions of heterogeneity into account, and carefully...

Rich people, women, and healthy people live longer. We document that this heterogeneity in life expectancy is large. We use an estimated structural model to assess the impact of life expectancy variation on the elderly's savings. We find that the differences in life expectancy related to...

Virtually all developed countries face projected budget shortfalls for their public pension programs. The shortfalls arise for two reasons. First, populations in developed countries are aging rapidly. Second, until recently older individuals in developed countries have been retiring earlier....

This paper constructs a model of saving for retired single people that includes heterogeneity in medical expenses and life expectancies, and bequest motives. We estimate the model using AHEAD data and the method of simulated moments. Out-of-pocket medical expenses rise quickly with age and...

This paper estimates the effect of Disability Insurance receipt on labor supply. We find that benefit receipt reduces labor force participation by 26 percentage points three years after a disability determination decision, although the reduction is smaller for those over age 55, college...

This paper estimates the effect of Disability Insurance receipt on labor supply, accounting for the dynamic nature of the application process. Exploiting the effectively random assignment of judges to disability insurance cases, we use instrumental variables to address the fact that those...

We document two new facts about the market-level response to minimum wage hikes: firm exit and entry both rise. These results pose a puzzle: canonical models of firm dynamics predict that exit rises but that entry falls. We develop a model of firm dynamics based on putty-clay technology and show...

We examine the key components that determine an individual's early career wage growth and how these factors have changed for less skilled workers over the last twenty years. In particular, we examine the relative importance of accumulating work experience as compared to the quality of job...

Following a minimum wage hike, household income rises on average by about $250 per quarter and spending by roughly $700 per quarter for households with minimum wage workers. Most of the spending response is caused by a small number of households who purchase vehicles. Furthermore, we find that...

This chapter discusses identification of common selection models of the labor market. We start with the classic Roy model and show how it can be identified with exclusion restrictions. We then extend the argument to the generalized Roy model, treatment effect models, duration models, search...
