The Effects of Children's Gender Composition on Filial Piety and Old-Age Support*
利用中国独生子女政策下双胞胎的自然实验，研究父母如何通过培养子女的孝道偏好来影响子女对养老的支持，发现父母更倾向于从收入禀赋较高的子女那里获取支持。
Abstract Do parents forge children’s preference for old-age support? Becker (1993) conjectures that the inculcation of filial piety increases parents’ investment in children’s human capital. We provide the first empirical evidence on parents’ instilling of filial piety in children, by combining the natural experiment of twins with China’s One-Child Policy to obtain exogenous variations in children’s gender composition. Among the different models of filial-piety inculcation, our empirical results favour a Beckerian model of altruism inculcation in which parents solicit support from the child with a higher earnings endowment.
