摘要
基于幂效用函数,建立代际交替模型,对养老保险影响居民储蓄的路径与机制进行了分析.通过数值模拟揭示了缴费率、工资替代率、利率和相对风险厌恶系数对居民最优储蓄水平的影响幅度.
The overlapping generations model was established based on the power utility function, and the path and the mechanism of influences of the old-age insurance on residents saving were analyzed. The numerical simulation shows the influences of contribution rate, wage replacement rate, interest rate and relative risk aversion coefficient on the optimal level of residents saving.
