报告简介：This paper studies the optimal investment and benefit adjustment problem for a collective DC (CDC) pension plan in an environment with parameter uncertainty. We propose a smooth ambiguity framework to model the pension trustee's preferences towards risk and ambiguity. Since the pension trustee is ambiguous about the risky assets, she/he decides to invest in a risk-free asset, a purely risky asset and an ambiguous risky asset whose return is uncertain. Furthermore, we take the stochastic salary into account. The objective is to maximize the expectation of the accumulated benefit payment and terminal wealth under a smooth ambiguity utility which is the double power form. The utility function makes the problem time-inconsistent and we establish the extended HJB equation via game theoretic formulation. The equilibrium strategy and equilibrium value function are derived under smooth ambiguity. Finally, sensitivity analysis of equilibrium strategy is provided to demonstrate the effects of model parameters on the equilibrium strategy.
