We report on an experiment designed to explore whether allowing individualsto voice their anger prevents costly punishment. For this sake, weuse an ultimatum minigame and distinguish two treatments: one in whichresponders can only accept or reject the o®er, and the other in which theycan also...

We investigate experimentally whether entry costs have an impact on the evolutionof cooperation in a social dilemma game. In particular, subjects repeatedly playthe so-called takeover game with anonymous partners randomly drawn from a fixedpopulation of participants. The game represents a social...

We examine the strategic behavior of first and second movers in a two party bargaining game with uncertain information transmission. When the first mover states her demand she does only know the probability with which the second mover will be informed about it. If the second mover is informed,...

One-way communication has been found to substantially increasecontributions in linear voluntary contribution mechanisms. We confirmthe robustness of this result in the presence of income heterogeneity.

We augment a standard dictator game to investigate how preferences for an environmental project relate to willingness to limit others’ choices. We explore this issue by distinguishing three student groups: economists, environmental economists, and environmental social scientists. We find that...

In the experiment two bureaucrats independently can grant a permit with the profit of the private party depending on when the permit is given. Whereas one bureaucrat can only veto the project, the second one has additional discretion in granting the permit earlier or later. (...)

Do contracts provide reference points that affect ex post behavior? We address this question in a canonical buyer-seller relationship with renegotiation. Our paper provides causal experimental evidence that an initial contract has a highly significant and economically important impact on...

A 2-round negotiation study provided evidence that positive feelings resulting from one negotiation can be economically rewarding in a second negotiation. Negotiators experiencing greater subjective value (SV) - that is, social, perceptual, and emotional outcomes from a negotiation - in Round 1...

We examine an evolutionary model of bargaining behavior in a society where resources are finite. Agents who develop better strategies for bargaining and trading come to dominate the population. We show that successful agents exhibit loss aversion and an "endowment effect." When information is...
