A Characterization of the Symmetrical Monotone Risk Aversion in the RDEU Model

Abstract

In a previous paper, Abouda and Chateauneuf proved that for RDEU maximizing MM with non-increasing marginal utility, positivity of the bid-ask spread can be identified with a very weak form of risk aversion SMRA. We perform here a more thorough study of SMRA, firstly in a general setting, and secondly in connection with the general RDEU model.
