摘要
考虑了一个带有死亡和伤残返还的DC型养老金计划的最优投资问题.以终端财富期望效用最大化为目标,利用动态规划原理建立相应的Hamilton-Jacobi-Bellman(HJB)方程,在双曲绝对风险厌恶(HARA)效用函数下得到最优解,通过数值模拟分析重要参数对最优投资策略的影响.
Abstract
This paper considers the optimal investment problem of a DC pension plan with death and disability re-turns.Taking the utility maximization problem of terminal wealth expectation as the goal,the corresponding Ham-ilton Jacobi Bellman(HJB)equation is established by using the principle of dynamic programming.The optimal solution is obtained under the Hyperbolic Absolute Risk Aversion(HARA)utility function,and the impact of im-portant parameters on the optimal investment strategy is analyzed through numerical simulation.
