Siblings, Teachers, and Spillovers on Academic Achievement
利用北卡罗来纳州的行政学校记录，研究发现教师经验不仅影响学生本人的成绩，还会溢出到其弟弟妹妹的学业表现，但对哥哥姐姐无显著影响，表明直接兄弟姐妹效应比家长行为反应更重要。
ABSTRACT:This study documents sibling spillover effects on child test score achievement using administrative school records from North Carolina. While teacher experience is a known determinant of student achievement, I show that teacher experience also affects the achievement of a child's younger siblings. In contrast, teacher experience does not have an effect on the test scores of the child's older siblings, suggesting that direct sibling effects rather than parental behavior responses are more important. These findings suggest that we are underestimating the importance of education inputs by ignoring the spillover effects on siblings.
