We examine the effects of leading by example in voluntary contributionexperiments. Leadership is implemented by letting one group membercontribute to the public good before followers do. Such leadershipincreases contributions in comparison to the standard voluntary contributionmechanism,...

In a stochastic duopoly market, sellers must form state-specific aspirationsexpressing how much they want to earn given their expectationsabout the other's behavior. We define individually and mutually satisficingsales behavior for given individual beliefs and aspiration profiles. In afirst...

There is robust field data showing that a frequent and successful way of looking fora job is via the intermediation of friends and relatives. Here we want to explore thisexperimentally. Participants first play a simple public good game with two interactionpartners ("friends"), and share whatever...

We experimentally explore individual and interactive decision making ina sequential search task and test whether generally accepted principles ofbounded rationality (aspiration formation, satisficing, and aspiration adjustment)adequately explain the observed search behavior. Subjects can, at...

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.

In the Yes/No game, like in the ultimatum game, proposer and respondercan share a monetary reward. In both games the proposer suggests a rewarddistribution which the responder can accept or reject (yielding 0-payoffs). Thegames only differ in that the responder does (not) learn the suggested...

Standard economic explanations of good conduct in trade rely almostexclusively on future-directed extrinsic motivations induced by materialincentives. But intrinsic motives to behave trustworthy and to punishuntrustworthiness do support trade. In our model, intrinsically motivatedplayers are...

Direct transfers allow heirs to freely use what has been passed on to them. Bequeathers who do not trust their descendants to make proper use of the fortune may prefer investing it in a safe foundation, thereby limiting their descendants’ autonomy. In our study we compare experimentally these...

Das Anspruchserfüllungskonzept mit seinen Bausteinen "Anspruchsbildung, Anspruchserfüllung und Anspruchsanpassung" ist die zentrale Idee in der Theorie des eingeschränkten rationalen Entscheidens. Ähnlich wie die Rationalwahltheorie, die ohne kühne Einschränkungen, zum Beispiel der...

Collusive agreements are often observed in procurement auctions. They are probablymore easily achieved when competitors’ costs are easily estimated. If, however, the individualcosts of bidders are private information, effective ring formation is difficult to realize.We compare experimentally...
