The health insurance characteristics of the population changes sharply at age 65 as most people become eligible for Medicare. But do these changes matter for health? We address this question using data on over 400,000 hospital admissions for people who are admitted through the emergency room for...

In this paper we document the importance of framing effects in the retirement savings decisions of college professors. Pensions in many post-secondary institutions are funded by a combination of an employer contribution and a mandatory employee contribution. Employees can also make tax-deferred...

In a classic paper, Schelling (1971) showed that extreme segregation can arise from social interactions in white preferences: once the minority share in a neighborhood exceeds a critical "tipping point," all the whites leave. We use regression discontinuity methods and Census tract data from...

In this paper, we review the literature on the "spike" in unemployment exit rates around benefit exhaustion, and present new evidence based on administrative data for a large sample of job losers in Austria. We find that the way unemployment spells are measured has a large effect on the...

This paper summarizes the findings from the first randomized evaluation of a job training program in Latin America. Between 2001 and 2005 the government of the Dominican Republic operated a subsidized training program for low-income youth in urban areas. The program featured several weeks of...

In the SSP Applicant Experiment, a random sample of new welfare entrants was informed that if they remained on welfare for a year they would become eligible for a generous earnings subsidy. Those who satisfied the waiting period and then left welfare and began working full time within the...

This paper presents new tests of the permanent income hypothesis and other widely used models of household behavior using data from the labor market. We estimate the "excess sensitivity" of job search behavior to cash-on-hand using sharp discontinuities in eligibility for severance pay and...

A regression discontinuity (RD) research design is appropriate for program evaluation problems in which treatment status (or the probability of treatment) depends on whether an observed covariate exceeds a fixed threshold. In many applications the treatment-determining covariate is discrete....

Racial segregation is often blamed for some of the achievement gap between blacks and whites. We study the effects of school and neighborhood segregation on the relative SAT scores of black students across different metropolitan areas, using large microdata samples for the 1998-2001 test...

Despite the adoption of no-fault Workers' Compensation legislation in most states, there is substantial litigation over the issue of employer liability for injury claims. We develop a sequential asymmetric information model of liability disputes and estimate the model using data on injury claims...
