Protective effect of adult children's education on parental survival in China: Gender differences and underlying mechanisms.

This study investigates whether adult children's education has a protective effect on parental survival, using data from all waves (2010-2018) of the China Family Panel Studies. We exploited the exogenous temporal and geographical variations in the enforcement of the 1986 compulsory schooling laws in China to construct an instrumental variable (IV) for adult children's education. The IV estimates indicated that the law-induced higher education of adult children led to sizeable improvements in the likelihood of paternal survival, although it had no significant effect on maternal survival. The protective effect on paternal survival was mainly driven by better-educated daughters, while sons' education had only a modest positive effect on maternal survival. Further evidence suggested that such heterogeneity by the gender of adult children might mainly come through more informal caregiving from better-educated daughters to older fathers with a limited role played by financial support from adult children.
