摘要
本文在一个引入消费攀比的离散时间、内生增长模型中,讨论了增长与储蓄的关系。在引入理性消费攀比后,不仅高储蓄可以导致高增长,高增长也可以导致高储蓄,其原因是攀比效应同时提高了现在消费和未来消费的边际效用,当公众提高当前消费时,会导致未来消费低于其他个体,从而造成个体未来效用的较大损失,这从理论上支持了增长导致储蓄的观点,也为近年来中国消费需求不旺、储蓄率偏高的问题提供了一个可能的解释。
In a discrete time, endogenous growth model with catching up with the Joneses, we show that higher saving rate can lead to higher growth rate, and higher growth rate can lead to higher saving rate also. Thus our discussion supports the viewpoint of Modigliani(1970) on growth to saving, and also gives an explanation for higher saving rates in China in recent years.
