| Abstract: | With the assumption of continuous-time model, this paper researches the optimal consumption and investment decision problem when the risky assets prices follow geometric Brown motion with stochastic volatility. Firstly the stochastic optimal control model for the optimal consumption and investment decision problem were established. Then the linear parabolic partial differential equation and the non-linearparabolic partial differential equation were obtained for the value function by using stochastic optimal control theory. |
