摘  要：We explore an optimal investment problem for a defined contribution (DC) pension plan member who can learning about the expected excess return of stock. The expected excess return of stock can be predicted both by an observable predictor and an unobservable predictor, and the member has to estimate the unobservable predicator by learning the history information. Moreover, the inflation risk and the stochastic salary are also considered in our model. By using the filtering technique and the stochastic optimal control, we derive the closed-form optimal investment strategy and the corresponding optimal value function for the DC pension plan with inflation and learning about stock return predictability. According to the theoretical and numerical results, we find that the hedging components in the optimal allocation on the inflation-indexed bond, which are used to hedge the risk arising from the stock return predictor, are more important than the corresponding hedging components on the stock. The correlations between the stock return predictors and the inflation-indexed bond have significant impact on the optimal investment strategy for DC pension plan. In addition, considerable welfare improvements may result from using the inflation-indexed bond either in learning about or hedging against the stock return predictors.
