The Effects of Foreign-Born Peers in US High Schools and Middle Schools
利用美国青少年纵向调查数据，研究发现外籍同学对本国学生和外籍学生的影响不同：外籍学生受益于更多外籍同学，在健康行为、社交孤立和心理健康方面有改善，但语言和学业成绩下降，不过成年后社会经济地位未受负面影响。
This study examines the short-term and long-term impact of being educated with immigrant peers. We leverage a quasi-experimental design using across-grade, within-school variation in cohort/grade composition for students in the National Longitudinal Study of Adolescent Health. We find positive effects for foreign-born students compared with native-born students from increasing exposure to other foreign-born students, including on risky health behaviors, social isolation, mental health, and academic effort. While we find negative effects on language and educational attainment, these differences do not translate into worse socioeconomic status in adulthood. Finally, we present evidence suggesting that these differential effects stem from highly segregated, school friendship networks.
