Risk- and ambiguity-averse portfolio optimization with quasiconcave utility functionals

Abstract

Motivated by recent axiomatic developments, we study the risk- and ambiguity-averse investment problem where trading takes place over a fixed finite horizon and terminal payoffs are evaluated according to a criterion defined in terms of a quasiconcave utility functional. We extend to the present setting certain existence and duality results established for the so-called variational preferences by Schied (2007). The results are proven by building on existing results for the classical utility maximization problem.
