In phase 1 of our experiment every participant plays the ultimatum game with each of the other five group members, each taking the role of proposer and responder. For each of the offers one learns how many participants would have accepted it. The pie is 30 times larger in phase 2. It thus pays...

It is often claimed that, if one could sense whether the other is going to cooperate or not, cooperators will manage to cooperate. Our experiment tries to shed new light on this debate. Participants could make their strategies in an asymmetric prisoner's dilemma game and a trust game dependent...

Players from two populations, predictors and predictees, are randomly matched in a game-theoretic version of Newcomb's Problem. Predictors are able to predict the predictees' choices by observing their type. There are two types of predictees, those who take their predictability into account by...

In plausible theories of bounded rationality actors are not stimulus-response machines but human beings. As such they are guided by theories that predict the course of the world and prescribe how they should try to intervene in that course. Since boundedly rational human beings cannot only...

Taking seriously the philosophical foundations of classical strategic theories of choice-making we scrutinize to what extent planning on equilibrium strategies can be justified "eductively" among rational players and how this can be utilizes to analyze games by their "game-like" sub-structures,...

In plausible theories of bounded rationality actors are not stimulus-response machines but human beings. As such they are guided by theories that predict the course of the world and prescribe how they should try to intervene in that course. Since boundedly rational human beings cannot only...

In equal punishment games like in ultimatum games first a proposer suggests how to split the pie, i.e. a positive monetary reward. Unlike in ultimatum games, the responder can decide among many (for proposer and responder) equal penalty payments. To exclude negative payoffs, punishment was...

By vetoing one question mutually efficient agreements. On the other hand, the threat of vetoing may prevent exploitation. Based on a generalization of ultimatum bargaining (Suleiman, 1996), we first elicit the responders' certainty equivalents for three different degrees of veto power....

Die Frage, welche Dartsellungsweise strategischer Interaktionen man als grundlegend für die spieltheoretische Analyse und insoweit als normale Form von Spielen anzusehen hat, ist keineswegs rein sprachlicher Natur. Systematische Gründe sprechen dafür, die Agentennormalform anstelle der...
