While the savings of retired singles tend to fall with age, those of retired couples tend to rise. We estimate a rich model of retired singles and couples with bequest motives and uncertain longevity and medical expenses. Our estimates imply that while medical expenses are an important driver of...

Using data from the Health and Retirement Survey, we document the changes in assets that occur before a person's death. Applying an event study approach, we find that during the 6 years preceding their deaths, the assets of single decedents decline, relative to those of similar single survivors,...

We use data from the Medicare Current Beneficiary Survey (MCBS) to document the medical spending of Americans aged 65 and older. We find that medical expenses more than double between ages 70 and 90 and that they are very concentrated: the top 10% of all spenders are responsible for 52% of...

This paper investigates the role played by informational frictions in college and the workplace. We estimate a dynamic structural model of schooling and work decisions, where individuals have imperfect information about their schooling ability and labor market productivity. We take into account...

As the workforce has become more educated, educational decisions are no longer just about whether to acquire more, but rather what type of education to pursue. In college, individuals somewhat specialize through their choice of college major. Further specialization occurs in graduate school....

This paper reviews the literature on affirmative action in undergraduate education and law schools, focusing in particular on the tradeoff between the quality of an institution and the fit between a school and a student. We first discuss the conditions under which affirmative action for...

We show that data on subjective expectations, especially on outcomes from counterfactual choices and choice probabilities, are a powerful tool in recovering ex ante treatment effects as well as preferences for different treatments. In this paper we focus on the choice of occupation, and use...

We estimate a model of drug demand and supply that incorporates insurance, advertising, and competition between branded and generic drugs within and across therapeutic classes. We use data on antiulcer drugs from 1991 to 2010. Our simulations show generics and ``me-too'' drugs each increased...

Conditional on enrollment, African American students are substantially less likely to graduate from 4-year public universities than white students. Using administrative micro data from Missouri, we decompose the graduation gap between African Americans and whites into four factors: (1) racial...

The low number of college graduates with science degrees -- particularly among under-represented minorities -- is of growing concern. We examine differences across universities in graduating students in different fields. Using student-level data on the University of California system during a...
