Recently a credibility crisis has taken hold across the social sciences, arguing that a component of Fischer (1935)’s tripod has not been fully embraced: replication. The importance of replications is not debatable scientifically, but researchers’ incentives are not sufficient to encourage...

Previous research indicates that risky and uncertain marginal returnsfrom the public good significantly lower contributions. This paper presentsexperimental results illustrating that the effects of risk and uncertainty dependon the employed parameterization. Specifically, if the value of the...

We use a two-person linear voluntary contribution mechanism with stochastic marginal benefits from the public good to examine the effect of imperfect information on contributions levels. To assess prior risk attitudes, individual valuations of several risky prospects are elicited via a...

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...

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...

What was once broadly viewed as an impossibility – learning from experimental data in economics – has now become commonplace. Governmental bodies, think tanks, and corporations around the world employ teams of experimental researchers to answer their most pressing questions. For their part,...

The recent literature on individual vs. group decisions over risk has brought about divergent results, mainly depending on the institutional rules through which groups take decisions. While some studies where group decisions relied on the majority rule showed no appreciable difference between...
