High School Employment and Youths' Academic Achievement
研究高中期间就业对青少年平均绩点的影响，发现就业及其滞后项对男女生的学业成绩有微小负面影响，且小时数效应在加入固定效应后减弱，工具变量估计下不显著。
Abstract This paper asks whether employment during high school impacts youths' grade point average. Unlike much of the prior literature, it allows for the endogeneity of the hours and dropout decisions, uses ASVAB test scores, and tests whether youth employment is dynamic. The results indicate that high school employment and its lag have small, negative impacts on academic grade point average for both males and females. The hours effects diminish when a fixed person effect is included, and they become statistically insignificant when hours are instrumented.
