In this paper, we first replicated Harrison et al. (2012). Then, we studied if the group’s size has an impact on group’s risk aversion. In line with Harrison et al. (2012), our results confirm that no significant differences occur between individuals and groups risk aversion in three-person...

We analysed dyads strategies in one-shot public goods game. By means of a laboratory experiment, using a variant of the strategy-method, we found that more than one third of the dyads are conditional cooperators, whereas 18% can be categorised as free riders.

The recent literature on individual and group choices over risk has led to different results. In some studies under unanimity, groups were found to be less risk averse than individuals, while those under majority did not highlight significant differences. However, both the types of studies...

While a basic theoretical principle in public economics assumes that individuals' behaviour is fully-optimizer with respect to the introduction of a tax, an increasing body of research is presenting evidence that agents decision making is often affected by non-negligible cognitive biases, which...

Environmental psychologists suggest that people feelings and emotions determine what they do and how they do it. According to the stimulus organism respons model (SOR), the environment creates a behavioral/emotional response in individuals that, in turn, induces approach or avoidance behaviors....

In this paper we aim - through an 'experimentally-adapted' Contingent Valuation survey - to look into the attributes of Ghanaians' willingness-to-pay for green products. This would help us addressing two main issues: first, from a theoretical point of view, we shall assess whether Ghanaians show...

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?”. It is well known that different methods differ in terms of the bias in the elicitation; it is rather less well-known that...

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...
