We define a coherent risk measures as set-valued maps satisfying some axioms. We show that this definition is a … convenient extension of the real-valued risk measures introduced by Artzner, Delbaen, Eber and Heath (1998). We then discuss the … aggregation issue, i.e. the passage from valued random portofolio to valued measure of Risk. Necessary and sufficient conditions …

This chapter of a collective book aims at presenting the basics of decision making under risk. We first define notions … of risk and increasing risk and recall definitions and classifications (that are valid independently of any … representation) of behavior under risk. We then review the classical model of expected utility due to von Neumann and Morgenstern …

The theory of existence of equilibrium with short-selling is reconsidered under risk and ambiguity modelled by risk … of the risk adjusted sets of expectations overlap. This condition is necessary if agents are not risk neutral at extreme … compatible trades, with non negative expected value with respect to any risk adjusted prior, strictly positive for some agent and …
