Sibling Influence on the Human Capital of the Left-Behind
利用RUMiC调查面板数据，首次研究兄弟姐妹互动对留守儿童学业表现的影响，发现父母外出务工增强了兄弟姐妹的影响，尤其是姐姐对弟弟妹妹有积极作用。
While a growing literature has analyzed the effects of parental migration on the educational outcomes of children left behind, this study is the first to highlight the importance of sibling interactions in such a context. Using panel data from the RUMiC Survey, we find that sibling influence on school performance is stronger among left-behind children. Hence, parental migration seems to trigger changes in familial roles and sibling effects among children. However, it is primarily older sisters who exhibit a positive influence on their younger siblings. We corroborate our results by performing a series of tests to mitigate endogeneity issues.
