摘要

我们利用基因组学的最新进展，重新审视经济学中的一个经典问题：父母如何应对孩子的天赋和兄弟姐妹的天赋差异？我们使用了一个基于DNA的指数，该指数在受孕时是固定的，并在兄弟姐妹之间随机分配，作为教育捐赠的代表。我们发现，非父母表现出对不平等的厌恶：考虑到一个孩子的绝对禀赋水平，如果他/她的兄弟姐妹受教育的遗传倾向较低，他们对他/她的投资就会减少。相比之下，我们没有发现任何证据表明异卵双胞胎的父母对孩子之间的禀赋差异有反应。

Sibling Differences in Genetic Propensity for Education: How Do Parents React?

We take advantage of recent advances in genomics to revisit a classic question in economics: how do parents respond to children's endowments and to sibling differences in endowments? We use an index based on DNA, which is fixed at conception and assigned randomly across siblings, as a proxy for educational endowments. We find that parents of nontwins display inequality aversion: given the absolute endowment level of one child, they invest less in him/her if his/her sibling has a lower genetic predisposition to education. In contrast, we find no evidence that parents of dizygotic twins react to endowment differences between children.
