题目：PATIENT CHOICE AND HOSPITAL QUALITY COMPETITION UNDER IMPERFECT INFORMATION （不完美信息下的患者选择与医院质量竞争）

报告人：Zhan Pang （庞湛）， Purdue University (普渡大学)

摘要Abstract:

Quality information imperfection is one of the most prominent characteristics of hospital markets where quality- and delay-sensitive patients make hospital choice without being fully informed. In a hospital market where hospitals compete on qualities under a regulated fee for service, we are interested in how imperfect quality information impacts patient choice and hospital quality decisions under competition, and whether a policy maker should leverage its payment incentive, or improve the quality information, or both, to govern the market.  

To account for the strategic interactions among patients, hospitals, and the policy maker, we employ the notion of rational expectations and the random utility theory to model the patient beliefs on qualities and expected delays and the resulting discrete choice behavior in a stochastic service system. We first characterize the structural properties of the rational expectations equilibrium (REE) and the Nash equilibria of hospital quality game.  We then characterize the impacts of imperfect quality information on patient choice under REE and the equilibrium qualities.  Interestingly, we show that improving quality information, though better informing patient choice, may not always lead to better equilibrium qualities.

To provide policy implications, we further analyze the optimal payment rate and quality information improvement effort of the policy maker.  We show that the payment incentive and the improvement in quality information tend to be substitutes. In particular, we identify conditions under which it suffices for the policy maker to use the payment incentives as the sole lever, making no effort to improve quality information to better inform patient choice, which implies that financial incentive may dominate quality information accuracy.  

This is joint work with Dr. Linggang Qi.
