ΠΕΡΙΛΗΨΗ

In this talk, the optimal portfolio selection problem is considered in a complete market environment under a particular disappointment aversion (Gul's type) utility function using classical results in a continuous time economy, obtained by martingale
and duality methods. Unlike the conventional expected utility maximization models, such a behavioral model can be easily miss-formulated if its different parameters do not coordinate well with each other. Thus, in the present version of the paper, a well and ill- posed problem is presented and discussed. To the best of our knowledge, for the first time, an analytic method to derive the formulas for the optimal wealth, the consumption and portfolio weight processes is presented. Finally, the standard CRRA utility is used to illustrate further the theoretical results obtained.
