Average-cost Pricing and Dynamic Selection Incentives in the Hospital Sector
CESifo, Munich, 2014
CESifo Working Paper No. 4977
This study investigates hospitals’ dynamic incentives to select patients when hospitals are remunerated according to a prospective payment system of the DRG type. Given that prices typically reflect past average costs, we use a discrete-time dynamic framework. Patients differ in severity within a DRG. Providers are to some extent altruistic. For low altruism, a downward spiral of prices is possible which induces hospitals to focus on low-severity cases. For high altruism, dynamic price adjustment depends on relation between patients’ severity and benefit. In a steady state, DRG prices are unlikely to give optimal incentives to treat patients.
