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.

同伴对青少年就寝时间决策的影响：具有采样数据的社交网络模型。

使用有关美国青少年代表性样本的独特信息，我们研究了青少年就寝时间决策中的同伴效应。我们扩展了空间自回归模型的非线性最小二乘估计器，以估计具有网络固定效应和对因变量进行抽样观察的网络模型。我们显示了忽略抽样问题会在多大程度上产生误导性推论结果。在考虑抽样时，我们发现，除了个人，家庭和同龄人的特征外，同龄人的就寝时间决定还有助于塑造自己的就寝时间决定。
