Abstract

We are interested in capacities which are deformations of probability, i.e. v=fring operatorP. We characterize balanced, totally balanced, and exact capacities by properties concerning the probability transformation function, f. These results allow us to obtain simple new characterizations of a large pattern of risk aversions relevant to Yaari's dual theory of choice under risk.
