Intergenerational transfer, human capital and long-term growth in China under the one child policy

Abstract

We suggest that the demographic changes caused by the one child policy (OCP) may not harm China's long-term growth. This is because of the higher human capital accumulation induced by the intergenerational transfer arrangements under China's poor-functioning formal social security system. Parents raise their children and depend on them for support when they reach an advanced age. A decrease in the number of children prompted by the OCP results in parents investing more in their children's education to ensure retirement consumption. In addition, decreased childcare costs strengthen educational investment through an income effect. Using a calibrated model, a benchmark with the OCP is compared to three counterfactual experiments without the OCP. Output in 2025 without OCP decreases about 4% under moderate estimates. The output gain comes from a greatly increased educational investment driven by fewer children (11.4years of schooling rather than 8.1). Our model sheds new light on the prospects of China's long-term growth by emphasizing the OCP's growth enhancing role through human capital formation under intergenerational transfer arrangements.
