We determine the increase of the maximum risk over the minimax risk in the case that the optimally robust estimator for … the relative risk is minimized in the case that the radius is known only to belong to some interval [pr, l'/p] " The … effect of increasing parameter dimension is studied for these models. The minimax increase of relative risk in ease p = 0 …

We introduce the notion of a convex measure of risk, an extension of the concept of a coherent risk measure defined in … Artzner et aL (1999), and we prove a corresponding extension of the representation theorem in terms of probability measures on … the underlying space of scenarios. As a case study, we consider convex measures of risk defined in terms of a robust not …

This paper presents a general theory that works out the relation between coherent risk measures, valuation bounds, and … preferences, in the way many coherent risk measures are somewhat generic. -- coherent risk rneasures ; valuation bounds … ; portfolio optirnization ; robust hedging ; convex cones ; dorninance relations ; convex duality ; incornplete rnarkets …
