Abstract

We take advantage of recent advances in behavioral genetics to revisit a classic question in economics: how do parents respond to children’s endowments and to differences in endowments among siblings? We use genetic variants that predict educational attainment, which are fixed at conception, as a measure of children’s educational endowments. We find that parents of singleton siblings 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 educational attainment. In contrast, parents of twins do not significantly react to endowment differences among their children.
