We conduct a laboratory experiment to study how, after a history of decay, cooperation in a repeated voluntary contribution game can be revived in an enduring way. Simply starting the repeated game over - a simple fresh start - leads to an initial increase of cooperation, but to a subsequent new...

Competition typically involves two main dimensions, a rivalry for resources and the ranking of relative performances. If socially recognized, the latter yields a ranking in terms of social status. The rivalry of resources resulting from interacting under a competitive incentive scheme has been...

We study an interactive framework that explicitly allows for non-rational behavior. We do not place any restrictions on how players can deviate from rational behavior. Instead we assume that there exists a lower bound p 2 [0; 1] such that all players play and are believed to play rationally with...

We use experiments to study the efficiency effects for a market as a whole of adding the possibility of forward contracting to a pre-existing spot market. We deal separately with the cases where spot market competition is in quantities and where it is in supply functions. In both cases we...

This paper uses subjects self-reported justifications to explain discrepancies between observed heterogeneous behavior and the unique equilibrium prediction in a one-shot travelers dilemma experiment (TD). Principal components (PC) analysis suggests that iterative reasoning, aspiration levels,...

We use subjects actions in modified dictator games to perform a within-subject classification of individuals into four different types of interdependent preferences: Selfish, Social Welfare maximizers, Inequity Averse and Competitive. We elicit beliefs about other subjects actions in the same...

We study how personal relations affect performance in organizations. In the experimental game we use a manager has to assign different degrees of decision power to two employees. These two employees then have to make distributive decisions which affect themselves and the manager. Our focus is on...

We conduct a laboratory experiment to study how advice affects the gender gap in the entry into a real-effort tournament. Our experiment is motivated by the concerns raised by approaching the gender gap through affirmative action. Advice is given by subjects who have already had some experience...

Various experimental procedures aimed at measuring individual risk aversion involve a list of pairs of alternative prospects. We first study the widely used method by Holt and Laury (2002), for which we find that the removal of some items from the lists yields a systematic decrease in risk...

We compare behavior in modified dictator games with and without role uncertainty. Subjects choose between a selfish action, a costly surplus creating action (altruistic behavior) and a costly surplus destroying action (spiteful behavior). While costly surplus creating actions are most frequent...
