Utility Maximization under Model Uncertainty in Discrete Time

Marcel Nutz

Papers from arXiv.org

Abstract: We give a general formulation of the utility maximization problem under nondominated model uncertainty in discrete time and show that an optimal portfolio exists for any utility function that is bounded from above. In the unbounded case, integrability conditions are needed as nonexistence may arise even if the value function is finite.
