Demographic Patterns and Household Saving in China
研究人口结构变化如何影响中国家庭储蓄率，使用世代交叠模型发现1955-2009年间人口变化解释了储蓄率上升的一半以上。
This paper studies how demographic variation affects the aggregate household saving rate. We focus on China because it is experiencing an historic demographic transition and has had a massive increase in household saving. We conduct a quantitative investigation using a structural overlapping generations model that incorporates parental care through support for dependent children and financial transfers to retirees. The saving decisions in the parameterized model mimic many of the features observed in the Chinese household saving rate time series from 1955 to 2009. Demographic change alone accounts for over half of the saving rate increase.
