Does Competition Improve Service Quality? The Case of Nursing Homes Where Public and Private Payers Coexist

讲座内容简介：

Competition plays an ambiguous role in markets for credence goods, where public and private payers coexist. Using nursing home data with a wide range of market structures, we find a U-shaped relationship between competition and service quality when nursing homes serve a mix of private and public segments, and a monotonic relationship when providers only serve the public segment. The outcomes can be explained by the interplay of two opposing effects of competition: the reputation building effect whereby competing firms choose high quality to build a good reputation and the rent extraction effect whereby competition hinders investment for quality improvements by eliminating price premia. These observations are consistent with a repeated game model that incorporates public and private payer segments. Overall, our U-shaped finding suggests that antitrust policy should consider a “rule of reason” to guide mergers in markets with endogenous quality.
