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...

This paper reports two laboratory studies designed to study the impact of public informationabout past departure rates on congestion levels and travel costs. Our experimental design isbased on a discrete version of Arnott, de Palma, and Lindsey’s (1990) bottleneck model wheresubjects have to...

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...

The satisficing approach with its three constituent processes, aspiration formation,satisficing, and aspiration adjustment, is formally elaborated for a specificclass of portfolio selection tasks. It is partly poorly confirmed by experimentaldata, indicating that bounded rationality requires...

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...

We propose an experimental design allowing a behavioral test of the axiom ofcompleteness of individual preferences. The central feature of our design consistsin enabling subjects to postpone commitment at a small cost. Our main result isthat preferences are significantly incomplete. We use...

Economic intuitions concerning rational behaviour in interactive social situations are shaped byidealized models which are regarded as “approximately true”. But ideal models cannot be meaningfullydeemed approximately true unless asymptotically convergent processes imply them as limit cases....

A vast literature shows that individuals frequently violate normative principles in reasoning. In evaluatingthe relevance of these findings for psychology, economics, and related disciplines, it is natural to askwhether reasoning errors reflect random aberrations or systematic biases. One...
