论文摘要
本文展示了自然(即一个人的遗传捐赠)和养育(即一个人的环境)如何在产生教育程度时相互作用。遗传捐赠是使用多基因分数来衡量的,以进行教育成果,而我们将出生顺序作为教育程度的重要环境决定因素。由于遗传捐赠是随机分配的家庭内部和与人的出生顺序正交的,因此我们的家庭固定效应方法利用了遗传捐赠和环境中的外源性变化。我们发现,与遗传捐赠较低的人相比,遗传捐赠较高的人比长子更受益。
This paper shows how nature (i.e., one's genetic endowments) and nurture (i.e., one's environment) interact in producing educational attainment. Genetic endowments are measured using a polygenic score for educational attainment, while we use birth order as an important environmental determinant of educational attainment. Since genetic endowments are randomly assigned within-families and orthogonal to one's birth order, our family fixed effects approach exploits exogenous variation in genetic endowments as well as environments. We find that those with higher genetic endowments benefit disproportionally more from being firstborn compared to those with lower genetic endowments.
