长期以来，身高被认为与更好的结果相关：问题是这种关联是否是因果关系。我们使用儿童的遗传变异作为工具变量来处理可能的未观察到的混杂因素，并检查儿童/青少年身高对广泛结果的影响：学习成绩，智商，自尊，抑郁症状和行为问题。OLS的研究结果表明，高个子的孩子智商更高，在学校表现更好，而且不太可能有行为问题。IV结果不同：高个子女孩（而不是男孩）有更好的认知表现，与OLS相反，更高的身高似乎会增加行为问题。我们研究了儿童的身高是否会对广泛的结果产生因果影响。我们使用儿童的遗传变异作为儿童身高的工具变量。研究结果表明，身高是影响人力资本积累的重要因素。我们表明，身高不仅可能带来优势，也可能带来劣势。
Height has long been recognized as being associated with better outcomes: the question is whether this association is causal. We use children's genetic variants as instrumental variables to deal with possible unobserved confounders and examine the effect of child/adolescent height on a wide range of outcomes: academic performance, IQ, self-esteem, depression symptoms and behavioral problems. OLS findings show that taller children have higher IQ, perform better in school, and are less likely to have behavioral problems. The IV results differ: taller girls (but not boys) have better cognitive performance and, in contrast to the OLS, greater height appears to increase behavioral problems. ► We examine whether height in children causally affects a wide range of outcomes. ► We use children's genetic variants as instrumental variables for child height. ► The results suggest that height is an important factor in human capital accumulation. ► We show that being tall may not only confer advantage but also disadvantage.
