Bereits im Jahre 1980 wählte Horst Albach einen spieltheoretischen und experimentellökonomischen Zugang zum Vertrauensproblem in der Ökonomik. Dieser Weg wird erneut beschritten. Es wird aufgezeigt, dass neuere spieltheoretische und experimentelle Arbeiten nicht nur die explanativen Grenzen...

The so-called paradox of democracy is approached as a variant of a more general class of so-called paradoxes of self-amendment. It is studied from a legal philosophy and a game theoretic point of view. Special attention is devoted to the risks and chances of inducing the foes of democracy to...

Applying an evolutionary framework, we investigate how a reputation mechanism and a buyer insurance (as used on Internet market platforms such as eBay) interact to promote trustworthiness and trust. Our analysis suggests that the costs involved in giving reliable feedback determine the gains...

If the (un)trustworthy are rare, people will talk about them, making their detection more reliable and / or less costly. When, however, both types appear in large numbers, detecting (un)trustworthiness will be considerably more difficult and possibly too costly. Based on Güth and Kliemt (2000)...

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

A two-persons bargaining problem often consists of initially incompatible demands that can be unilaterally reduced by sequential concessions. In a 2 x 2 x 2-factorial design we distinguish between reliable and unreliable concessions, between a static and dynamic settings and between symmetric...

This paper aims to experimentally investigate how individual willingness to pay for a lottery is affected by using a new way of representing of probabilistic ambiguity. Thus we can see how individual valuation reacts to different degrees of ambiguity probability information provided to subjects....

Assuming inequality averse subjects as modeled by Fehr and Schmidt (1999) or in the ERC model by Bolton and Ockenfels (2000) in ultimatum games with asymmetric conflict payoffs allows to make predictions especially concerning responder acceptance thresholds. These predictions are tested in a...

Arguably the most important campaign finance regulations in U.S. federal elections are limitsimposed on the amount that an individual or organization may donate to a federal campaign. Suchcontribution limits are advocated on two separate grounds. The first is that they prevent corruption,the...
