摘要
研究一类证券市场中投资组合及消费选择的最优控制问题.在随机干扰源相互关联情形下,运用动态规划方法,对一类典型的效用函数CRRA(ConstantRelativeRiskAversion,常数相对风险厌恶)情形,得到了最优投资组合及消费选择的显式解,并给出了最优解的经济解释和关于部分参数的灵敏度分析.
In this paper, one kind of optimal control problem of investment portfolio and consumption choice in the security market is studied. The optimal investment portfolio and consumption choice for one kind of typical utility function-CRRA case(Constant Relative Risk Aversion) are obtained by using the dynamical programming method where the random disturbances are correlative.The economical explanation and sensitivity analysis about some parameters for the optimal solution are given.
