Hospital response to prospective payment: Moral hazard, selection, and practice-style effects
研究医院在预付费制下如何通过改变服务强度、患者类型或市场份额来应对激励变化，并利用新罕布什尔州医疗补助精神病出院数据分离这三种效应。
In response to a change in reimbursement incentives, hospitals may change the intensity of services provided to a given set of patients, change the type (or severity) of patients they see, or change their market share. Each of these three responses, which we define as a moral hazard effect, a selection effect, and a practice-style effect, can influence average resource use in a population. We develop and implement a methodology for disentangling these effects using a panel data set of Medicaid psychiatric discharges in New Hampshire. We also find evidence for the form of quality competition hypothesized by Dranove (1987).
