Is there a Causal Effect of High School Math on Labor Market Outcomes?
利用一项高中试点计划，该计划降低了选择高级数学的成本，从而识别出高级数学对劳动力市场结果的因果效应，发现数学对收入有正面影响，部分原因是这些学生最终获得了更高学历。
In this paper, we exploit a high school pilot scheme to identify the causal effect of advanced high school math on labor market outcomes. The pilot scheme reduced the costs of choosing advanced math because it allowed for a more flexible combination of math with other courses. We find clear evidence of a causal relationship between math and earnings for students who are induced to choose math after being exposed to the pilot scheme. The effect partly stems from the fact that these students end up with a higher education.
