由于语言技能的内在性，语言技能对收入影响的研究变得复杂。本研究利用年龄较小的儿童比年龄较大的儿童更容易学习语言这一现象，构建了一个语言水平的工具变量。我们发现，英语熟练程度对儿童时期移民到美国的成年人的工资有显著的积极影响。这种影响似乎大部分是通过教育来调节的。非英语国家和英语国家之间的差异，可能使移民从后者的非语言年龄到达效果的控制组不好，似乎并没有推动这些研究结果。
Research on the effect of language skills on earnings is complicated by the endogeneity of language skills. This study exploits the phenomenon that younger children learn languages more easily than older children to construct an instrumental variable for language proficiency. We find a significant positive effect of English proficiency on wages among adults who immigrated to the United States as children. Much of this effect appears to be mediated through education. Differences between non-English-speaking origin countries and English-speaking ones that might make immigrants from the latter a poor control group for nonlanguage age-at-arrival effects do not appear to drive these findings.
