This paper examines the impact of social distrust on household saving in China using a microsample from the China Family Panel Studies (CFPS). We find that social distrust leads to an increase in savings within households, in which households not living alone, with higher levels of education and urban households are more affected. We also find that social distrust affects household savings through raising risk expectations, reducing credit availability and amplifying risk spillovers from real estate markets.

We build a unified framework to quantitatively examine population aging and credit market frictions in contributing to Chinese economic growth between 1977 and 2014. We find that demographic changes together with endogenous human capital accumulation account for a large part of the rise in per capita output growth, especially after 2007, as well as some of the rise in savings. Credit policy changes initially alleviate the capital misallocation between private and public firms and lead to significant increases in both savings and output growth. Later, they distort capital allocation. While contributing to further increase in savings, the distortion slows down economic growth. Among factors that we consider, increased life expectancy and financial development in the form of reduced intermediation cost are the most important in driving the dynamics of savings and growth.
