Abstract：

We consider an optimal investment problem for a defined-contribution (DC) pension member who are loss-averse, faces inflation and longevity risks and requires a minimum performance at retirement. The loss-aversion is characterized by an S-shaped utility. We provide a fully analytical characterization of the optimal investment strategy in an indexed bond, a stock and a risk-free asset by using the martingale approach. Our theoretical and numerical results show that the percentages of wealth invested in risky assets usually have a V-shaped pattern with respect to the growing of reference point level, and increases along with the rising lifespan. There are additional hedging components in the portfolio due to the salary and minimum performance constraint. The salary causes her to invest less aggressively in index bond. While the minimum performance offsets the effect of salary. Furthermore, our results have some important implications for the management of a DC pension plan.
