We investigate risk averse agents who manage risk by trading financial securities in a market that we call a risk … market. We assume this market is perfectly competitive and complete. When risk aversion is expressed using risk measures, the … probability distributions defines a novel template for equilibria under uncertainty and, more specifically, equilibria under risk …

This paper presents a new axiomatic characterization of risk measures that are additive for independent random … variables. In contrast to previous work, we include an axiom that guarantees monotonicity of the risk measure. Furthermore, the …. The risk measure characterized can be regarded as a mixed exponential premium. …

We compare seven established risk elicitation methods and investigate how they robustly explain eleven kinds of risky … behavior with 760 individuals. Risk measures are positively correlated; however, their performance in explaining behavior is … heterogeneous and, therefore, difficult to assess ex ante. To close this knowledge gap, greater diversification across risk measures …

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 …

Many practitioners annualize VaR just like the standard deviation. We show that this approach is incorrect, and a more sophisticated formula should be used for deriving a periodic VaR from parameters of the daily returns distribution. Another problem addressed here is the distribution of daily...

Considerable literature has been devoted to developing statistical inferential results for risk measures, especially … a number of risk measures that are of the form of ratios, or even more complex combinations, of two L-functionals. In … the present paper we call such combinations ‘coupled risk measures' and develop a statistical inferential theory for them …
