We study the short-term impact of Connecticut's Jobs First welfare reform experiment on women’s labor supply and program participation decisions. A non-parametric optimizing model is shown to restrict the set of counterfactual choices compatible with each woman's actual choice. These revealed...

Beginning in the 1880s, southern states introduced pensions for Confederate veterans and widows. They continued to expand these programs through the 1920s, while states outside the region were introducing cash transfer programs for workers, poor mothers, and the elderly. Using legislative...

Across a wide set of non-group insurance markets, applicants are rejected based on observable, often high-risk, characteristics. This paper argues private information, held by the potential applicant pool, explains rejections. I formulate this argument by developing and testing a model in which...

We examine the relationship between the adoption of EMR and hospital operating costs. We first identify a puzzle that has been seen in prior studies: Adoption of EMR is associated with a slight cost increase. We draw on the literature on IT and productivity to demonstrate that the average effect...

We re-present and re-examine the analysis from the famous RAND Health Insurance Experiment from the 1970s on the impact of consumer cost sharing in health insurance on medical spending. We begin by summarizing the experiment and its core findings in a manner that would be standard in the current...

Carbon markets are substantial and they are expanding. There are many lessons from experiences over the past eight years: fewer free allowances, better management of market-sensitive information, and a recognition that trading systems require adjustments that have consequences for market...

Prison overcrowding is a perennial problem and several states are under court order to reduce crowding. The long-term solution to crowding has been more prisons. The short-term solution is early release. Early release programs can be effective when they balance the savings of reduced prison...

We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources...

This paper measures the causal effect of time out of the labor force on subsequent employment of Social Security Disability Insurance (SSDI) applicants and distinguishes it from the discouragement effect of receiving disability benefits. Using a unique Social Security Administration workload...

I consider how online postsecondary education, including massive open online courses (MOOCs), might fit into economically sustainable models of postsecondary education. I contrast nonselective postsecondary education (NSPE)in which institutions sell fairly standardized educational services in...
