报告摘要:
In this paper, we consider the optimal investment and benefit payment problem for a target benefit pension (TBP) plan with default risk and model uncertainty. The pension fund is invested in a risk-free asset, a stock and a defaultable bond. The objective is to maximize the wealth and benefit excess from the target value or minimize the wealth and benefit gap from the target value with CARA utility. Applying stochastic control approach, we establish the Hamilton-Jacobi-Bellman equations for both the post-default case and the pre-default case, respectively. Robust optimal investment strategies and benefit payment adjustment strategies are derived explicitly for the two cases. We also consider the no-ambiguity model for degenerate case and compare the results under two cases. Numerical analyses are provided to illustrate the effects of parameters on the optimal strategies and demonstrate properties of the strategies.
