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 …

Theory suggests that people facing higher uninsurable background risk buy more insurance against other risks that are … casualty insurance increases with earnings uncertainty. This finding is consistent with consumer preferences being … characterized by decreasing absolute prudence. …

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 …

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 …

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 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 …

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 …

In this Paper we develop a model of intertemporal portfolio choice where an investor accounts explicitly for the possibility of model misspecification. This work is motivated by the difficulty in estimating precisely the probability law for asset returns. Our contribution is to develop a...
