Abstract : The portfolio selection problem with one safe asset and risky assets is analyzed via a new decision theoretic criterion: the Optimized Certainty Equivalent(OCE), recently introduced by the authors. Fundamental results in portfolio theory, previously studied under the Expected Utility criterion (EU), such as separation Theorems, comparative statistics analysis, and threshold values for inclusion or exclusion of risky assets in the optimal portfolio, are obtained here. In contrast to the EU model, our results for the OCE maximizing investor do not impose restrictions on either the utility function or the underlying probability laws. We also derive a dual portfolio selection problem and provide it with economic interpretation.
