Our contribution is to develop a framework that allows for ambiguity about the joint distribution of returns … for all stocks being considered for the portfolio, and also for different levels of ambiguity for the marginal … international equity returns. The calibration shows that when the overall ambiguity about the joint distribution of returns is high …

The paper reports the result of an experimental game on asset integration and risk taking. We find evidence that … winnings in earlier rounds affect risk taking in subsequent rounds, but no evidence that real life wealth outside the … experiment affects risk taking. We find some evidence of imitation of the risk taking behavior of others that is distinct from …

This experimental study is concerned with the impact of the timing of the resolution of risk on people’s willingness to … inferred from decisions regarding hypothetical choice problems, we had participants put their own money at risk in a real … period under delayed resolution (which involved two days). Affective traits and risk attitudes were measured through a web …

Despite the … substantial heterogeneity across subjects, decreasing absolute risk aversion and increasing relative risk aversion are the most … prevalent risk types, and we can classify more than 50% of the subjects in this combined category. We also find evidence of …

This paper presents new evidence on the distribution of risk attitudes in the population, using a novel set of survey … representative sample of 450 subjects, and find that the general risk question is a good predictor of actual risk-taking behavior.
