In this paper, we present experimental evidence of causation running from reliance on intuition to risk and ambiguity … lowers the probability of being ambiguity averse by 30 percentage points and increases risk tolerance by about 30 percent in …

utility function. We then fit the experimental choices to this model to assess the risk attitude of our subjects. 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 …

As an extension, we esimate the … various models using transformations of the ‘true’ probabilities to decision weights. The estimated degree of risk aversion … increases further, while players tend to overestimate substantially their chances of winning. Constant Relative Risk Aversion …

This paper shows that a strictly increasing and risk averse utility function with decreasing absolute risk aversion is … necessarily differentiable with a positive and absolutely continuous derivative. The cumulative absolute risk aversion function …, called the absolute risk aversion density, is a generalization of the coefficient of absolute risk aversion, and it is well …

This paper analyzes the effects of network positions and individual risk attitudes on individuals' strategic decisions … factors, such as the number of (direct) neighbors, local clustering and individuals' risk attitudes. …

We show that in order to determine whether one decision-maker is more risk averse than another, it is sufficient to … comparisons of risk aversion can be made even in situations of ‘background risk’. Since expected utility becomes a function of … mean and standard deviation, risk aversion can be measured by the marginal rate of substitution between mean and standard …

Using a large sample of retail investors as well as experimental data we find that risk and ambiguity aversion are … positively correlated. We show the common link is decision style: intuitive thinkers tolerate more risk and ambiguity than … find that risk and ambiguity aversion vary with individual characteristics and wealth. The wealthy are less risk averse but …

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 …

We analyse bidding behaviour in auctions when risk-averse buyers bid for a good whose value is risky. We show that when … risk in the valuations increases, DARA bidders will reduce their bids by more than the appropriate increase in the risk … marginal utility of income increases with risk, so buyers are reluctant to bid so highly. We also show that precautionary …
