摘  要: In this talk we will investigate the optimal portfolio selection problems for n interacting investors in a continuous time framework. We first consider portfolio selection problem for agents when they take the performance of their peers into account. We provide tractable formulations of relative performance concerns between n risk averse agents in a continuous-time setting, and solve for their equilibrium policies in closed-form. Sensitivity analysis and numerical examples are also provided to illustrate how the Nash equilibrium policies and the utility loss change when some model parameters vary. Second we will consider the optimal portfolio selection problems for n interacting investors when they cooperate with each other. We also provide tractable formulations of cooperation between n risk averse agents in a continuous-time setting, and solve for their equilibrium policies in closed-form. We give the condition under which cooperation can improve agents' expected terminal wealth utility.
