英文摘要：
The birth order literature emphasizes the role of parental investments in explaining why firstborns have higher human capital outcomes than their laterborn siblings. We use birth order as a proxy for investments and interact it with genetic endowments. Exploiting only within-family variation in both ensures they are exogenous as well as orthogonal to each other. As such, our setting is informative about the existence of dynamic complementarity in skill production. Our empirical analysis exploits data from 15,019 full siblings in the UK Biobank. We adopt a family-fixed effects strategy combined with instrumental variables to deal with endogeneity issues arising from omitted variables and measurement error. We find that birth order and genetic endowments interact: those with above-average genetic endowments benefit disproportionally more from being firstborn compared to those with below-average genetic endowments. This finding is a clean example of how genetic endowments (nature) and the environment (nurture) interact in producing educational attainment. Moreover, our results are consistent with the existence of dynamic complementarity in skill formation: additional parental investments associated with being firstborn are more effective for those siblings who randomly inherited higher genetic endowments for educational attainment.

中文摘要：
出生顺序文献强调了父母投资在解释为什么第一胎比第二胎的兄弟姐妹有更高的人力资本产出方面的作用。我们使用出生顺序作为投资的代理，并将其与遗传禀赋相互作用。仅利用两种基因的家族内变异可以确保它们是外生的，并且彼此正交。因此，我们的背景是关于技能生产中存在动态互补性的信息。我们的实证分析利用了来自英国生物银行15019名全同胞的数据。我们采用家庭固定效应策略结合工具变量来处理因遗漏变量和测量误差而产生的内生性问题。我们发现出生顺序和遗传禀赋是相互作用的：与遗传禀赋低于平均水平的人相比，遗传禀赋高于平均水平的人从长子身上获得的好处更大。这一发现是遗传禀赋（自然）和环境（养育）如何相互作用产生教育成就的一个清晰例子。此外，我们的结果与技能形成中动态互补性的存在是一致的：与长子相关的额外父母投资对那些随机继承了较高教育成就遗传禀赋的兄弟姐妹更有效。
