We report the results of an experimental study that compares voting mechanisms in the provision of public goods. Subjects can freely decide how much they want to contribute. Whether the public good is ¯nally provided is decided by a referendum under full information about all contributions. If...

We experimentally test how acceptance thresholds react to the decision of the proposer in a three party ultimatum game to exclude one of two responders with veto power from the game. We elicit responder acceptance thresholds in case the proposer decides to exclude one of them, what increases the...

We experimentally test whether intentional and observable discriminatory pay of symmetric agents in the Winter (2004) game causes low paid agents to reduce effiort. We control for intentionality of wages by either allowing a principal to determine wages or by implementing a random process. Our...

In three party ultimatum games the proposer can first decide whether to exclude one responder, what increases the available pie. The experiments control for intentionality of exclusion and veto power of the third party. We do not find evidence for indirect reciprocity of the remaining responder...

We experimentally investigate competition in innovation in a patent race scenario. Pairs of subjects compete as seller firms on a duopoly market, engaging in risky search investments. Successful innovation is rewarded through temporary monopoly rents. Throughout the interaction, subjects receive...

This article reports the results of a simple bargaining experiment on the ultimatum-revenge game. The game enables to differentiate between fairness that is stimulated by intentional based motives, distributional motives, and fairness considerations that mix both motives. The laboratory...

We analyse two team settings in which one member in a team has stronger incentives to contribute than the others. If contributions constitute a sacrifice for the strong player, the other team members are more inclined to cooperate than if contributions are strictly dominant for the strong player.

Under a great variety of legally relevant circumstances, people have to decide whether or not to cooperate, when they face an incentive to defect. The law sometimes provides people with sanctioning mechanisms to enforce pro-social behavior. Experimental evidence on voluntary public good...

Laboratory experiments by Fudenberg and Pathak (2010), and Vyrastekova, Funaki and Takeuch (2008) show that punishment is able to sustain cooperation in groups even when it is observed only in the end of the interaction sequence. Our results demonstrate that the real power of unobserved...
