This paper analyzes and compares the incentive properties of some common payment mechanisms for GPs, namely fee for service (FFS), capitation and fundholding. It focuses on gatekeeping GPs and it speci…cally recognizes GPs heterogeneity in both ability and altruism. It also allows inappropriate...

The main question raised in this paper is whether GPs should self select their paymentmechanism or not. To answer it, we model GPs' behavior under the most commonpayment schemes (capitation and fee-for-service) and when GPs can select one amongthose. Our analysis considers GPs heterogeneity in...

We devise an experiment to explore the effect of different degrees of competition on optimal contracts in a hidden-information context. In our benchmark case, each principal is matched with one agent of unknown type. In our second treatment, a principal can select one of three agents, while in a...

Cooperation among people who are not related to each other is sustained by the availability of punishment devices which help enforce social norms (Fehr and Gächter, 2002). However, the rationale for costly punishment remains unclear. This paper reports the results of an experiment investigating...
