Risk assessment under different possible scenarios is a source of uncertainty that may lead to concerning financial losses. We address this issue, first, by adapting a robust framework to the class of spectral risk measures. Second, we propose a Deviation-based approach to quantify uncertainty. Furt...

We first prove the noteworthy fact that Central Dominance with m=1 (CD1), introduced by Gollier (1995), is a particular case of Second order Stochastic Dominance. We then introduce a new tractable class of dominance that we name Relative order and we prove that this class is a strict subclass of CD1...

This paper presents a characterization of weak risk aversion in terms of preference for sure diversification. Similarly, we show that strong risk aversion can be characterized by weakening preference for diversification,as introduced by Dekel (Econometrica 57:163,1989), in what we call preference fo...

In this paper, we examine the effect of a decrease in risk on the demand for risky asset in the standard portfolio problem. We introduce a new class of dominance, that we name relative order and we prove that this class of dominance is consistent both with central dominance introduced by Gollier [5]...

In this paper, we deal with the basic two-period consumption saving problem where the first and second period consumption utility, respectively v is assumed to be concave as usually. Considering the usual assumption of identify of u and v, we show that prudence is fully characterized by the convexit...

In this paper, we deal with the basic two-period consumption–saving problem where the first- and second-period consumption utilities, v and u, are assumed to be concave, respectively, as usually. We prove that for the rank-dependent utility model, prudence is fully characterized by the convexity of...
