Using artefactual field and lab experiments to investigate how fee-for-service and capitation affect medical service provision

We analyze how physicians, medical students, and non-medical students respond to nancial incentives from fee-for-service and capitation. We employ a series of artefactual eld and conventional lab experiments framed in a physician decision-making context. Physicians, participating in the eld, and medical and non-medical students, participating in lab experiments, respond to the incentives in a consistent way: Signi - cantly more medical services are provided under fee-for-service compared to capitation. Our ndings are robust regarding subjects' gender, age, and personality traits.
