摘要
本文在考虑代际收入转移的家庭消费—储蓄决策中,根据消费的特点将家庭消费分为耐用品消费和非耐用品消费,并引入财产保险和人寿保险,讨论家庭在耐用品、非耐用品、保险、风险投资和教育等方面的最优支出决策问题。模拟结果显示,本文模型能够很好拟合家庭实际支出结构。通过敏感性测试发现:风险投资和生存保险之间存在替代关系;教育无法替代且独立于个体的风险态度;耐用品组合的折旧率对耐用品消费具有决定性的影响;个体的风险态度和效用折现率都会在较大程度上影响消费和投资需求。

The simulation result showed that the model fitted with actual household expend iture structure quite well. The sensitivity test found that：the substitution relation between risky asset and survival in- surance was verified ; human capital investment couldn＇ t be substituted and it was independent of individuals＇ risk aversion coefficient;the rate of depreciation of durables had important influence on durables consumption;individu- als＇ risk aversion coefficient and discount factor of utility had great effects on consumption and investment.
