| 内容提要 | 本文基于两期世代交替模型分析讨论了预期寿命对家户储蓄和健康投资支出的双重影响，并利用2004-2009年我国城镇住户调查数据和全国疾病监测系统死因监测数据库，采用固定效应法和工具变量法对理论模型所推导出来的假说进行实证检验。理论模型表明，预期寿命在通过改变贴现因子直接影响年轻人储蓄的同时，也直接影响他们的健康投资。尤其是当人们预期到未来老年时期的寿命水平较低时，他们有更强的激励在年轻时期增加健康投资支出。实证结果表明，当城市层面的平均预期寿命上升时，个体家户的储蓄会显著增加，而家户健康投资支出的负担则会显著降低,与理论模型预测基本一致。 |
| Abstract | The paper constructs a two-period overlapping generations model to study the impact of life expectancy on household savings and health investment, and based on 2004-2009 China Urban Household Survey data and National Diseases Surveillance Points System data, uses fixed effect method and instrumental variable method to test the model results. The theoretical model shows that by modifying the individual lifecycle discounting factor, the life expectancy not only affects the young’s savings but also the their health investment. Especially when the young expect lower life expectancy at old age, they have stronger incentive to increase present heath investment. Consistent with the theory prediction, the empirical results shows that when the life expectancy at city level increases, the savings of individual household will significantly increases and the burden of household health investment expenditure will significantly decline. |
