A General Index Of Inherent Risk

Free registration required

Executive Summary

The authors extend the pioneering work of Aumann and Serrano by presenting an index of inherent riskiness of a gamble having the desirable properties of their index, while being applicable to gambles with either positive or negative expectations. As such, the index provides a measure of riskiness which is of use for both risk lovers and risk aversive gamblers, and is defined for all discrete and a large class of continuous gambles. They analyze these properties of the index, and present in addition three empirical applications - roulette, horse betting market and US options traded on financial stocks between 2005 and 2007.
