Intergenerational and Sibling Spillovers in High School Majors
利用瑞典高中招生断点回归设计，发现兄弟姐妹和代际间存在显著的专业选择溢出效应，且受性别组合影响，对专业性别构成有重要影响。
This paper estimates family spillovers in high school major choice in Sweden, where admission to oversubscribed majors is determined based on GPA. Using a regression discontinuity design, we find large sibling and intergenerational spillovers that depend on the sex mix of a dyad. Same-sex siblings copy one another, while younger brothers recoil from an older sister’s choices. Fathers and mothers influence sons but not their daughters, except when a mother majors in the male-dominated program of engineering. Back-of-the-envelope calculations reveal that these within-family spillovers have sizable implications for the sex composition of majors.
