Whether behavior converges toward rational play or fair play in repeated ultimatum games depends on which player yields first. If responders concede first by accepting low offers, proposers would not need to learn to offer more, and play would converge toward unequal sharing. By the same token,...

In a situation, where it is efficient for one of two parties to pollute but highly inefficient if both parties do so, the harmed third party can freely impose its damage claims on both parties what crucially determines which equilibrium to expect. Whereas "equality before the law" requires equal...

A group of actors, individuals or firms, can engage in collectively providing projects which may be costly or generating revenues and which may benefit some and harm others. Based on requirements of procedural fairness (Güth and Kliemt, 2013), we derive a bidding mechanism determining...

Will the fact that a person is selected among others on the basis of personal information affect that person's behavior? In our experiment participants first answer a personality questionnaire. They then play a 3-person game: one of the three players decides, after inspecting the personality...

We consider three-person envy games with a proposer, a responder, and a dummy player. In this class of games, the proposer, rather than allocating a constant pie, chooses the pie size which the responder can then accept or reject while the dummy player can only refuse his own share. While the...

Banning deception in economic experiments does not exclude experiments with participants in the role of experimenters who can gain by deceiving those in the role of participants. We compare treatments with and without possible deception by experimenter-participants to test whether deception...

Based on an axiomatically derived provision rule allowing community members to endogenously determine which, if any, public project should be provided, we perform experiments where (i) not all parties benefit from provision, and (ii) the projects' "costs" can be negative. In the tradition of...

We study conditional cooperation based on a sequential two-person linear public good game in which a trusting first contributor can be exploited by a second contributor. After playing this game the first contributor is allowed to punish the second contributor. The consequences of sanctioning...

A long time ago most economists would have limited themselves to stating that agreements should be individually rational and efficient and that selecting a specific agreement from that set depends on bargaining and negotiation power whatever that may be. Nowadays hardly any economist will argue...
