Data and Code for: Impacts of Performance Pay for Hospitals: The Readmissions Reduction Program

US policy increasingly ties payments for providers to performance on quality measures, though little empirical evidence guides the design of such incentives. I deploy administrative data to study a large federal program that penalizes hospitals with high readmissions rates. Using policy-driven variation in the penalty incentive across hospitals for identication, I nd that hospital responses to the penalty account for two-thirds of the observed decrease in readmissions over this period, as well as a decrease in heart at-tack mortality. Quality improvement accounts for about half of the decrease in readmissions; the remainder is explained by selective admission of returning patients.
