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. Specifically, if the value of the...

In this paper we investigated group size impact on risk aversion when a majority rule is applied. Drawing on the widely used Holt and Laury’s (2002) lottery pairs, we observed a risky shift for both individual and groups regardless of their size. However, groups choices are shown to be closer...

The theoretical approach in dealing with the aggregation of information in markets in general, and financial markets in particular considers information as an exogenous element to the system, focusing just on conditions and consequences of the efficient incorporation of information into prices....

A theory is said to be fully absorbable whenever its own acceptance by all of the individuals belonging to a certain population does not question its predictive validity. This accounts for strategic equilibria and can be related to the logic underlying convergence of behaviour and intentional...

In the context of eliciting preferences for decision making under risk, we ask the question: which might be the 'best' method for eliciting such preferences?ʺ. It is well known that different methods differ in terms of the bias in the elicitation; it is rather less well-known that different...
