Social institutions regulating group conduct have been regarded as necessaryfor human cooperation to transcend family bonds. However, manystudies in economics and biology indicate that reciprocity based on repeatedinteraction suffices to establish cooperation with non-kin. We shedlight on the...

Each of several exchange partners is the monopoly owner of a specific commoditywhich she can share with others. It is optimal to keep the own endowment, but allwould gain by mutual gift exchange. Participants play the game repeatedly in constantgroups (partner design) and can establish stable...

Fairness is a strong concern as shown by dictator and ultimatum experiments. Efficiency, measured by the sum of individual payoffs, is a potentially competing concern in games such as the prisoners' dilemma. In our experiment participants can increase efficiency by gift giving. In the one-sided...

Economists usually treat human behavior as being determined by the shadow of the future, while most other social scientists point to the shadow of the past. This paper considers experimental evidence relevant to the controversy and tries to reconcile both explanations of human behavior with each...

In this paper, we introduce the concept of payoff distortion inthe standard prisoner’s dilemma game when strategies are driven by psychologicalbehaviors. This concept enables to take account each player’s assessmentof the other player’s behavior and the asymmetry of information....

We present an experimental test of a shirking model where monitoring intensityis endogenous and effort a continuous variable. Wage level, monitoring intensityand consequently the desired enforceable effort level are jointly determined bythe maximization problem of the firm. As a result,...

To explain potential sources of wage rigidity this article analyzes a model of reciprocalkindness applied to a repeated ultimatum game with changing and nonzeroconflict payoffs. The model is also tested in a laboratory experiment. The resultsare compatible with the rentsharingapproach to wage...

We examine the degree of trust and reciprocity in an experimental trust game with 662 participants from six different age groups, ranging from 8 year old primary school children to retired persons in their late sixties. Although both trust and reciprocity have been identified as fundamental...

Two firms, each consisting of a team with the owner and just oneemployee, compete on the labor market with free labor mobility. Afterobserving the investment decisions by firm owners their employees canengage in costly training, thus increasing their general and firm-specificproductivity, which...

We analyze the effects of introducing asymmetric information andexpectations in the investment game (Berg et al., 1995). In our experiment,only the trustee knows the size of the surplus. Subjects’expectations about each other’s behavior are also elicited. Our resultsshow that average payback...
