Peer effects in bedtime decisions among adolescents: a social network model with sampled data
利用美国青少年代表性样本数据，研究同伴就寝时间决策对个人就寝时间的影响，并改进网络模型以处理抽样问题，发现同伴效应显著。
Using unique information on a representative sample of US teenagers, we investigate peer effects in adolescent bedtime decisions. We extend the nonlinear least-squares estimator for spatial autoregressive models to estimate network models with network fixed effects and sampled observations on the dependent variable. We show the extent to which neglecting the sampling issue yields misleading inferential results. When accounting for sampling, we find that, besides the individual, family and peer characteristics, the bedtime decisions of peers help to shape one's own bedtime decision.
