In our model, a service provider makes strategic quality choices and short-lived customers are asked to evaluate the observed quality by providing ratings to a reputation system. The customer is not able to always evaluate the service quality correctly and possibly submits an erroneous rating according to a predefined probability. Considering reputation profiles of the last three sales, within the theoretical model we derive that the service provider’s dichotomous quality decisions are independent of the reputation profile and depend only on the probabilities of receiving positive and negative ratings when providing low or high quality. Thus, a service provider optimally either maintains a good reputation or completely refrains from any reputation building process. However, when mapping our theoretical model to an experimental design we find that a significant share of subjects in the role of the service provider deviates from optimal behavior and chooses actions which are conditional on the current reputation profile.

Previous research has shown that, without competition, physicians deviate from patient‐optimal treatment under payment systems like capitation and fee‐for‐service. Although competition might reduce these distortions, physicians usually interact with each other repeatedly over time and only a fraction of patients switches providers at all. Both patterns might prevent competition to work in the desired direction. To analyze the behavioral effects of competition, we develop a theoretical benchmark that is then tested in a controlled laboratory experiment. Experimental conditions vary physician payment and patient characteristics. Real patients benefit from provision decisions made in the experiment. Our results reveal that, in line with the theoretical prediction, introducing competition can reduce overprovision and underprovision, respectively. The observed effects depend on patient characteristics and the payment system, though. Tacit collusion is observed and particularly pronounced with fee‐for‐service payment, but it appears to be less frequent than in related experimental research on price competition. }}, author = {{Brosig-Koch, Janet and Hehenkamp, Burkhard and Kokot, Johanna}}, journal = {{Health Economics}}, number = {{53}}, pages = {{6--20}}, publisher = {{Wiley Online Library}}, title = {{{The effects of competition on medical service provision}}}, doi = {{10.1002/hec.3583}}, volume = {{26}}, year = {{2017}}, } @techreport{1055, author = {{Hehenkamp, Burkhard and Kaarboe, Oddvar}}, publisher = {{Universität Paderborn}}, title = {{{Location Choice and Quality Competition in Mixed Hospital Markets}}}, year = {{2017}}, } @techreport{1056, author = {{Gu, Yiguan and Hehenkamp, Burkhard and Leininger, Wolfgang}}, publisher = {{Universität Paderborn}}, title = {{{Evolutionary Equilibrium in Stochastic Contests - Entry, Effort, and Overdissipation}}}, year = {{2017}}, } @techreport{1083, abstract = {{In actual school choice applications the theoretical underpinnings of the Boston School Choice Mechanism (BM) (complete information and rationality of the agents) are often not given.

And how does a conflict develop into terrorism, a guerilla war, or a major conventional civil war, or is resolved peacefully? We develop a formal model for rebels and government and derive optimal choices. Further, we focus on three elements as important ingredients of a "destabilization war". All three of these - large random events, time preference (which we relate to ideology), and choice of duration of fight - are rarely considered in formal conflict theory. We can answer the above two questions using game theory analysis. First, insurgents rise up because they hope to destabilize through permanent challenging attacks. In this context, large randomness is an important ally of rebels. While each individual attack may have a low impact, at some point a large random event could lead to success. Hence, the duration of activities is a constitutive element of this kind of armed conflict. Patience (low time preference), which may reflect rebels' degree of ideological motivation, is crucial.
