Ambiguity aversion is captured in several ways, i.e. as a discount factor net of a risk premium, and as an estimated … intermediate levels of ambiguity aversion. Moreover, we find risk aversion to be statistically unrelated to ambiguity aversion on …

We analyze spectral risk measures with respect to comparative risk aversion following Arrow (1965) and Pratt (1964) on … widely-applied spectral Arrow-Pratt-measure is not a consistent measure of Arrow-Pratt-risk aversion. A decision maker with a … decision maker with a smaller spectral Arrow-Pratt-measure. We further show how a proper measure of Arrow-Pratt-risk aversion …

Auctions often involve goods exhibiting a common knowledge ex-post risk. Precautionary bidding predicts that under … expected utility, ex-post risk leads DARA bidders to reduce their bids by more than the appropriate risk premium. Because the … degree of riskiness of the good, and bidders risk aversion, are difficult to observe in field settings, we conduct …
