In this paper, I present an empirical model of learning under ambiguity in the context of clinical trials. Patients are concern with learning the treatment effect of the experimental drug, but face the ambiguity of random group assignment. A two dimensional Bayesian model of learning is proposed...

This paper uses variation in traffic safety laws and obesity rates to identify substitution patterns between living and cadaveric kidney donors. Using panel data from 1988-2008, we find that a 1% decrease in the supply of cadaveric donors per 100,000 increases the supply of living donors per...

This paper uses a two-year panel dataset on hospitals from the American Hospital Association (AHA) to evaluate the effect a policy change has on the marginal product of medical residents. A weighted 2SLS approach is used to estimate a semi-parametric production function. A policy restricting...
