Child Labor and Learning
利用巴西学生标准化测试的微观面板数据，通过固定效应估计发现，上学期间工作对数学和葡萄牙语成绩有负面影响，成绩下降5%到13%标准差，相当于损失四分之一到五分之三学年的学习量。
This article investigates the impact of working while in school on learning outcomes through the use of a unique micropanel data set of the standardized test scores of Brazilian students. The potential endogeneity of school performance and child work is addressed through the use of fixed-effects estimators. A negative effect of working on learning outcomes in both math and Portuguese is found. The effects of child work range from 5% to 13% of a standard deviation decline in test score, which represents a loss of about one-quarter to three-fifths of an average year of learning. Robustness checks confirm the main conclusions.
