主题： Optimal Post-Retirement Planning for Couples with Dependent Mortality

摘要

    This paper develops a computationally tractable multi-period consumption and portfolio choice model for retired couples with dependent mortality rates. This new model enables us to unveil the significant role of mortality correlation in shaping a household’s optimal post-retirement saving, investing and spending. Compared to independent couples, dependent couples optimally purchase less joint annuities but more single annuities and have higher total annuity holdings. The higher annuity holdings make dependent couples favor risky assets more than bonds. They also enable dependent couples to enjoy higher joint-life consumption. If dependent couples ignore the mortality dependence, the total demand for annuities will be substantially lower than the optimal level, leading to a lower overall utility. Using the optimal level suggested by our model as a benchmark, we show that the prevalence of ignorance and indifference about mortality dependency observed in reality is one important factor that explains the annuity puzzle. Our comparison also uncovers the value-added mechanism of joint annuities: joint annuities improve welfare by smoothing the trajectory of consumption per household member.
