The One-Child Policy and Household Saving∗ Taha Choukhmane Nicolas Coeurdacier Keyu Jin Yale SciencesPo and CEPR London School of Economics This Version: July 7, 2017 Abstract We investigate whether the `one-child policy' has contributed to the rise in China's household saving rate and human capital in recent decades. In a life-cycle model with intergenerational transfers and human capital accumulation, fertility restrictions lower expected old-age support coming from children|inducing parents to raise saving and education investment in their offspring. Quantitatively, the policy can account for at least 30% of the rise in aggregate saving. Using the birth of twins under the policy as an empirical out-of-sample check to the theory, we find that quantitative estimates on saving and education decisions line up well with micro-data.
