A conditional cooperator in a public goods game wants to match his partners' expected contribution. We investigate theoretically and empirically whether (and to what extent) conditional cooperation can explain how individual contributions evolve in a repeated two-person public goods experiment...

Spieltheoretische Überlegungen zeigen, dass Reputationsmechanismen, wie sie auf Internet-Marktplattformen zur Anwendung kommen, prinzipiell geeignet sind, Handel in großen anonymen Märkten zu erleichtern. Dies gilt selbst dann, wenn die Marktteilnehmer ihre Identität jederzeit und kostenlos...

We report on a research program that employs the indirect evolutionary approach to analyze how the institutional environment drives the evolution of trust and trustworthiness through the evolution of moral preferences, and how in turn the evolution of preferences shapes the evolution of the...

This paper purports to provide experimental evidence explaining a number of stylized facts associated with the behaviour of financial returns, in particular, the fat tailed nature of their distribution and the persistence in their volatility. By means of a laboratory experiment, we will...

This paper aims to integrate both economic and sociological notions of conventions in a single analytical framework. To this end, it starts by distinguishing conceptually between behavioral convention, i.e. an arbitrary but stable social regularity, and normative convention, i.e. a principle of...

Trust that suppliers and buyers will keep their word is a necessary ingredient to a well functioning marketplace. Nowhere is the issue trickier than for electronic markets, where transactions tend to be geographically diffuse and anonymous, putting them out of the reach of the legal safeguards...

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

To commit credibly in bargaining is crucial: In the ultimatum game with its one-sided early commitment power the “proposer” gets (nearly) the whole pie while the “responder” is left with (almost) nothing. When both parties commit simultaneously the (a)symmetric Nash(1950)-bargaining...

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

A procurement contract is granted by a bureaucrat (the auctioneer) who is interested in a low price and a bribe from the provider. The optimal bids and bribes are derived based on an iid private cost assumption. In the experiment, bribes are negatively framed (betweensubjects treatment) to...
