Average‐Cost Pricing and Dynamic Selection Incentives in the Hospital Sector
研究了按诊断相关分组预付制下医院选择患者的动态激励，发现价格变动取决于医院利他程度和患者病情与收益的关系，稳态下DRG定价难以提供最优治疗激励。
This study investigates dynamic incentives to select patients for hospitals that are remunerated according to a prospective payment system of the diagnosis-related group (DRG) type. Using a model with patients differing in severity within a DRG, we show that price dynamics depend on the extent of hospital altruism and the relation between patients' severity and benefit. Upwards and downwards price movements over time are both possible. In a steady state, DRG prices are unlikely to give optimal incentives to treat patients. Depending on the level of altruism, too few or too many patients are treated. DRG pricing may also give incentives to treat low-severity patients even though high-severity patients should be treated.
