We study how the health and health insurance coverage of Mexican immigrants change with time in the US. Cross-sectional analyses suggest that approximately three decades of residency in the US is associated with a 9 to 11 percentage point (12% to 15%) decline in the probability of being...

We construct and test a new model of employer-provided health insurance provision in the presence of adverse selection in the health insurance market. In our model, employers cannot observe the health of their employees, but can decide whether to offer insurance. Employees sort themselves among...

The current practice of measuring age as years-since-birth, both in common practice and in the law, rather than alternative measures reflecting a person's stage in the lifecycle distorts important behavior such as retirement, saving, and the discussion of dependency ratios. Two alternative...

A variety of public campaigns, including the "Just Say No" campaign of the 1980s and 1990s that encouraged teenagers to "Just Say No to Drugs", are based on the premise that teenagers are very susceptible to peer influences. Despite this, very little is known about the effect of school peers on...

Societies socialize children about sex. This is done in the presence of peer-group effects, which may encourage undesirable behavior. Parents want the best for their children. Still, they weigh the marginal gains from socializing their children against its costs. Churches and states may...

There is conflicting evidence on the importance of out-of-pocket medical expenditures as a risk to financial security, particularly at older ages. We revisit this question, focusing on health care spending near the end of life using data from the Health and Retirement Study for the years...

Charter schools were developed, in part, to serve as an R&D engine for traditional public schools, resulting in a wide variety of school strategies and outcomes. In this paper, we collect unparalleled data on the inner-workings of 35 charter schools and correlate these data with credible...

We measure the impact of individuals' looks on life satisfaction/happiness. Using five data sets, from the U.S., Canada, the U.K., and Germany, we construct beauty measures in different ways that allow placing lower bounds on the effects of beauty. Beauty raises happiness: A one...

We develop a theory of intergenerational transmission of preferences that rationalizes the choice between alternative parenting styles (as set out in Baumrind 1967). Parents maximize an objective function that combines Beckerian altruism and paternalism towards children. They can affect their...

We provide new evidence on the the cyclical behavior of household size in the United States from 1979 to 2010. During economic downturns, people live in larger households. This is mostly, but not entirely, driven by young people moving into or delaying departure from the parental home. We assess...
