In dieser experimentellen Studie untersuchen wir das kooperative Verhalten von Offizieren (bzw. Offiziersanwärtern) der Bundeswehr. Dabei betrachten wir ihre Interaktionen sowohl untereinander als auch gegenüber zivilen Probanden. Unsere Kernhypothesen sind, dass sich die angehenden Offiziere...

In this experimental study we examine the behavior of Bundeswehr officers and officer candidates regarding their willingness to cooperate. Due to the military training which focuses on comradeship and reliable teamwork even under extreme conditions, we expect a strong bond between soldiers and...

How malleable are people's fairness ideals? Although fairness is an oft-invoked concept in allocation situations, it is still unclear whether and to what extent people's allocations reflect their fairness ideals. We investigate in a laboratory experiment whether people's fairness ideals vary...

We study optimal direct mechanisms for a credence goods expert who can be altruistic or spiteful. The expert has private information about her distributional preferences and possibly also about her customer's needs. We introduce a method that allows the customer to offer separate contracts to...

This paper studies the evolution of both characteristics of reciprocity - the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, preferences for rewarding as well as preferences for punishing can survive evolution provided individuals interact within...

Despite recent advances in reputation technologies, it is not clear how reputation systems can affect human cooperation in social networks. Although it is known that two of the major mechanisms in the evolution of cooperation are spatial selection and reputation-based reciprocity, theoretical...

We study credence goods markets where an expert not only cares for her own monetary payoff, but also for the monetary payoff of her customer. We show how an expert with heterogeneous distributional preferences responds to monetary incentives in the absence of institutions, under liability and/or...

I suppose that people react with anger when others show themselves not to be minimally altruistic. With heterogeneous agents, this can account for the experimental results of ultimatum and dictator games. Moreover, it can account for the surprisingly large fraction of individuals who offer an...

Value Surveys may reveal well-behaved societies by the statistical treatment of the agents` declarations of compliance with social values. Similarly, the results of experiments conducted on games with conflict of interest trace back to two important primitives of social capital trust and...
