Is there a Causal Effect of High School Math on Labor Market Outcomes?
利用高中试点计划降低选课成本，识别出高中数学对收入有因果效应，部分通过提高教育水平实现。
<p style="text-align: left">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.
