We study how competition between physicians affects the provision of medical care. In our theoretical model, physicians are faced with a heterogeneous patient population, in which patients systematically vary with regard to both their responsiveness to the provided quality of care and their...

Tullock's analysis of rent-seeking is reconsidered from an evolutionary point of view. We show that evolutionarily stable behavior in a rent-seeking contest differs from efficient rent-seeking behavior in a Nash equilibrium. We explore that implications of evolutionary stability for rent-seeking...

Including the entry decision in a Bertrand model with imperfectly informed consumers, we introduce a trade-off at the level of social welfare. On the one hand, market transparency is beneficial when the number of firms is exogenously given. On the other, a higher degree of market transparency...

We propose a dynamic model that explains why individuals may be reluctant to pick up work although the wage is above their reservation wage. Accepting low paid work will put them in an adverse position in future wage bargaining, as employers could infer the individual's low reservation wage from...

We study evolutionarily stable strategy (ESS) in contests where participation is stochastic. When participation probabilities are given, players exert more effort In ESS than under Nash. Ex-ante overdissipation occurs when participation is suff. likely and discriminative power of the contest...

We explore how competition between physicians affects medical service provision. Previous research has shown that, in the absence of competition, physicians deviate from patient-optimal treatment under payment systems like capitation and fee-for-service. While competition might potentially...

We explore how competition between physicians affects medical service provision. Previous research has shown that, without competition, physicians deviate from patient-optimal treatment under payment systems like capitation and fee-for-service. While competition might reduce these distortions,...

Der Nobelpreis für Wirtschaftswissenschaften 2007 wurde an Leonid Hurwicz, Eric S. Maskin und Roger B. Myerson für Ihre grundlegenden Beiträge zur Mechanismus-Design-Theorie vergeben. Worin liegt der Erfolg der Mechanismus-Design-Theorie begründet? Was sind ihre Perspektiven?
