英文摘要:
We study the optimal investment-consumption problem for a member of defined contribution plan during the decumulation phase. For a fixed annuitization time, to achieve higher final annuity, we consider a variable consumption rate. Moreover, to have a minimum guarantee for the final annuity, a safety level for the wealth process is considered. To solve the stochastic optimal control problem via dynamic programming, we obtain a Hamilton-Jacobi-Bellman (HJB) equation on a bounded domain. The existence and uniqueness of classical solutions are proved through the dual transformation. We apply the finite difference method to find numerical approximations of the solution of the HJB equation. Finally, the simulation results for the optimal investment-consumption strategies, optimal wealth process and the final annuity for different admissible ranges of consumption are given. Furthermore, by taking into account the market present value of the cash flows before and after the annuitization, we compare the outcomes of different scenarios.

中文摘要:
我们研究了固定缴款计划成员在递减阶段的最优投资消费问题。对于固定的年金化时间,为了获得更高的最终年金,我们考虑可变的消费率。此外,要为最终年金提供最低保障,需要考虑财富过程的安全水平。为了用动态规划方法求解随机最优控制问题,我们在有界区域上得到了一个Hamilton-Jacobi-Bellman(HJB)方程。通过对偶变换证明了经典解的存在唯一性。我们应用有限差分法寻找HJB方程解的数值近似值。最后,给出了不同允许消费范围下最优投资消费策略、最优财富过程和最终年金的仿真结果。此外,通过考虑年金化前后现金流的市场现值,我们比较了不同情景的结果。
