Previous research indicates that risky and uncertain marginal returns from the public good significantly lower contributions. This paper presents experimental results illustrating that the effects of risk and uncertainty depend on the employed parameterization. Speci?cally, if the value of the...

Unter Fundamentalentscheidungen verstehen wir Entscheidungen bzw. Entscheidungssituationen von existenzieller Wichtigkeit. Dabei stehen wenige grundlegende Handlungsalternativen zur Wahl, die sich jedoch erheblich in ihren Wirkungen unterscheiden. Es handelt sich im Unternehmensbereich um...

In standard market theory demand and cost functions have to be known to compute optimal price or quantity responses. In case of risk or uncertainty the decisions depend on expectations, i.e. estimated parameters. Even in case of rational inference these expectations itself are uncertain, at...

Hoheitliche Länderrisiken im hier beschriebenen Sinne sind bankbetriebliche Risiken, die im internationalen Kreditgeschaet durch die Zahlungsunfähigkeit oder -unwilligkeit der ausländischen Regierung entstehen. Länderrisiko-Analysen untersuchen folglich die Frage nach der Bonität eines...

Empirical studies show that decisions deviate from the predictions of expected utility theory and violate the axiomatic foundations. Hence, many generalizations to non-expected utility theory have been developped. But empirically they did not provide an improvement over the standard approach. In...

This paper investigates whether language priming activates different cultural identities and norms associated with the language communicated with respect to social preference and risk attitudes. Our contribution is on identifying the conditions where there will be language priming effects. We...

Cumulative Prospect Theory (PT) introduced the weighting of probabilities as an additional component to capture risk attitudes. However, this addition would be a less significant challenge to expected utility theory (EU) if utility curvature and probability weighting showed strong positive...

Gender-specific patterns of self-selection into competitive and cooperative environments may have multiple reasons. One of the most prominent explanations to this point is, that there are inherent differences between men and women when it comes to preferences regarding competition. We take a...

Data on contestants' choices in Italian Game Show Affari Tuoi are analysed in a way that separates the effect of risk attitude (preferences) from that of beliefs concerning the amount of money that will be offered to contestants in future rounds. The most important issue addressed in the paper...

Preference for control affects investment behavior. Participants of laboratory experiments invest different amount of money in a risky asset when face with two different methods of control which have identical payoff structure and probability distribution, but provide different sense of control....
