We elicit subjects' willingness to pay to reduce future risk. In our experiments, subjects are given a cash endowment … probability sessions, suggesting that this bias robustly persists in environments including both risk and future uncertainty, and …

Agents face an ambiguous risk of biodiversity survival as well as ambiguous expected losses from its extinction. As a …'être. Low risk will provoke unconditional social free-riding in both models. Les agents font face à un risque ambigu quant à la …

This paper distinguishes relative risk aversion and resistance to intertemporal substitution in climate risk modeling …. It shows that higher risk aversion increases the optimal carbon tax. Higher resistance to intertemporal substitution … alone has the same effect as increasing the discount rate, provided that the risk is not too large. We discuss implications …

We experimentally test whether risk aversion or ambiguity aversion can explain decisions in a learning-by-doing game …. We first measure subjects' preferences toward risk and ambiguity, and then use these measures to predict behavior in the … game. We find that ambiguity averse subjects pay more often to resolve ambiguity, and we find that less risk averse …
