contributions. This paper presents experimental results illustrating that the effects of risk and uncertainty depend on the employed … efficiency gains, the presence of risk and uncertainty about the public good's value is not detrimental to cooperation. This … ?nding casts doubt on the hypothesis that risk and uncertainty, per se, weaken people's willingness to contribute. …

environmental quality means financing depollution activities and uncertainty concerns its efficiency since it's not always clear or … certain what effects will result from a reduction of pollution. We show that if an agent is sufficiently risk averse … has two possible consequencies which depend on agent risk aversion. Therefore, understanding the implication of …

We explored experimentally how threshold uncertainty affects coordination success in a threshold public goods game …. Whereas all groups succeeded in providing the public good when the exact value of the threshold was known, uncertainty was … generally detrimental for the public good provision. The negative effect of threshold uncertainty was particularly severe when …

examine the effect of imperfect information on contributions levels. To assess prior risk attitudes, individual valuations of … clear evidence of risk aversion, and of a negative relationship between the latter and willingness to cooperate. …
