When randomly assigning participants to experimental roles and the according payment prospects, participants seem to receive “manna from heaven.” In our view, this seriously questions the validity of laboratory findings. We depart from this by auctioning off player roles via the incentive...

In this paper we compare behaviour in a newspaper experiment with behaviour in the laboratory. Our workhorse is the Yes-No game. Unlike in ultimatum games responders of the Yes-No games do not know the proposal when deciding whether to accept or not. We use two different amounts that can be...

We report on an experiment using video technology to study effects of communication on donations to and discrimination between potential receivers. The experimental design eliminates strategic factors by allowing two receivers to unilaterally communicate with an anonymous dictator before the...

Take-it or leave-it offers are probably as old as mankind. Our objective here is, first, to provide a, probably subjectively-colored, recollection of the initial ultimatum game experiment, its motivation and the immediate responses. Second, we discuss important extensions of the standard...

We suggest that procedures of monetarized bidding can facilitate co-operation in Elinor Ostrom type common(s) projects without crowding out communitarian faculties of "self-governance". Axioms securing procedurally egalitarian bidding on the basis of declared monetary evaluations are introduced....

Bounded rationality questions backward induction, which however, does not exclude such reasoning when anticipation is easy. In our stochastic (alternating offer) bargaining experiment, there is a certain first-period pie and a known finite deadline. What is uncertain (except for the final...

Concessions try to avoid conflict in bargaining and can finally lead to an agreement. Although they usually are seen as unfolding in time, concessions can also be studied in normal form or by conditioning only on failure of earlier agreement attempts. We experimentally compare three protocols of...

This paper derives and justifies a procedurally fair bidding mechanism and reviews experiments that apply the mechanism to public projects pro- vision. In the experiments, not all parties benefit from provision, and the projects' costs can be negative. The experimental results indicate that the...
