In the experiment two bureaucrats independently can grant a permitwith the profit of the private party depending on when the permit is given.Whereas one bureaucrat can only veto the project, the second one hasadditional discretion in granting the permit earlier or later. We speakof greasing when...

We conducted a laboratory study with a public goods game in which contributions are not submitted all at once but incrementally as coordinated in real time by a clock. Individuals press a button as soon as the clock equals their willingness to contribute. This public goods institution exploits...

Retributive responses do play a role in human behavior. Whether they are primarily triggered by supposed intentions or by observed consequences of actions is an important question. It can be addressed by experimental studies of retributive responses in situations in which the individual actor...

Contrary to the models of deterministic life cycle saving, we take itfor granted that uncertainty of one's future is the essential problem ofsaving decisions. However, unlike the stochastic life cycle models, we capturethis crucial uncertainty by a non-Bayesian scenario-based...

We study an ultimatum experiment in which the responder does not know the offer when accepting or rejecting. Unconditional veto power leads to acceptances, although proposers are significantly greedier than in standard ultimatum games, and this is anticipated by responders.

Similar to Levati and Neugebauer (2001), a clock is used by which participantscan vary their individual contributions for voluntarily providing apublic good. As time goes by, participants either in(de)crease their contributiongradually or keep it constant. Groups of two poorly and two...

In this paper we study the robustness of the deadline effect in bargaininggames using constant and slowly decreasing pies, different time horizons,and both constant and alternating role modes. With decreasing pies efficiency requires early agreements while constant pies allow for efficient late...

We study ultimatum and dictator experiments where the first moverchooses the amount of money to be distributed between the playerswithin a given interval, knowing that her own share is fixed. Thus, thefirst mover is faced with scarcity, but not with the typical trade-off betweenher own and the...

Relying on the specific example of ultimatum bargaining experiments this paper explores the possible role of empirical knowledge of behavioural "norm(ative) facts" within the search for (W)RE – (Wide) Reflective Equilibria on normative issues. Assuming that "pro-social" behaviour...
