We develop a method that allows one to compute incomplete-market equilibria routinely for Markovian equilibria (when they exist). The main difficulty to be overcome arises from the set of state variables. There are, of course, exogenous state variables driving the economy but, in an incomplete...

We examine the effect of New York City's universal pre-kindergarten program (UPK) on the health and utilization of children enrolled in Medicaid using a difference-in-regression- discontinuities design. We find that UPK increases the probability that a child is diagnosed with asthma or with...

We show how to construct a ranking of U.S. undergraduate programs based on students' revealed preferences. We construct examples of national and regional rankings, using hand-collected data on 3,240 high-achieving students. Our statistical model extends models used for ranking players in...

The practice of adopting adults, even if one has biological children, makes Japanese family firms unusually competitive. Our nearly population-wide panel of postwar listed nonfinancial firms shows inherited family firms more important in postwar Japan than generally realized, and also performing...

This paper studies the effect of mothers' education on fertility in a population with very low female labor force participation. The results we present are particularly relevant to many countries in the Muslim world where 70-80 percent of women are still out of the labor force. For...

We are the first to examine the effect of Superfund cleanups on infant health rather than focusing on proximity to a site. We study singleton births to mothers residing within 5km of a Superfund site between 1989-2003 in five large states. Our "difference in differences" approach compares birth...

We exploit an exogenous health shock--the birth of a child with a severe health condition--to investigate the causal effect of a life shock on homelessness. Using survey data from the Fragile Families and Child Wellbeing study that have been augmented with information from hospital medical...

Recent research shows that health at birth is affected by many factors, including maternal education, behaviors, and participation in social programs. In turn, endowments at birth are predictive of adult outcomes, and of the outcomes of future generations. Exposure to environmental pollution is...

In this paper, we investigate the impact of attending school on body weight and obesity. We use school starting age cutoff dates to compare weight outcomes for similar age children with different years of school exposure. As is the case with academic outcomes, school exposure is related to...

A number of studies have found substantial correlations in risky behavior between siblings, raising the possibility that adolescents may directly influence the actions of their brothers or sisters. We assess the extent to which correlations in substance use and selling drugs are due to causal...
