First-Generation Elite: The Role of School Social Networks
研究发现，非精英背景的高中生较少拥有精英家庭出身的同伴，这种社交资本差异是精英教育代际传递的关键。通过抽签评估和因果中介分析，揭示了精英同伴对大学申请和收入的正面影响，并指出增加精英与非精英学生的混合能改善社会流动性。
High school students from non-elite backgrounds are less likely to have peers with elite-educated parents than their elite counterparts. This difference in social capital is a key driver of the high intergenerational persistence in elite education. We identify a positive elite peer effect on enrollment in elite programs and labor market earnings, then disentangle underlying mechanisms. Exploiting a lottery in assessment, a causal mediation analysis shows the overall positive peer effect reflects a positive effect on application behavior (conditional on GPA). When considering income mobility, we find that further mixing between high school elite and non-elite students could improve mobility.
