论文摘要
经验研究经常忽略部分观察到的网络中缺少网络链接的问题。在研究网络互动的情况下，研究计划的溢出效益时，本文解决了这个问题。我们的方法足够灵活，可以说明非i.i.d。缺少链接。它依赖于两个网络度量，可以根据同一观察到的网络的传入和传出链接轻松构建它们。如果所有单位都有网络度的界限，则可以识别和始终估计的处理和溢出效应。如果某些单元的网络度不受限制，我们还证明了我们方法的偏差降低属性。实施了对现实世界网络数据的蒙特卡洛实验和自然主义模拟，以验证我们方法的有限样本性能。我们还重新检查了家庭计算机使用对儿童自我授权学习的溢出影响。
The issue of missing network links in partially observed networks is frequently neglected in empirical studies. This paper addresses this issue when investigating the spillovers of program benefits in the presence of network interactions. Our method is flexible enough to account for non-i.i.d. missing links. It relies on two network measures that can be easily constructed based on the incoming and outgoing links of the same observed network. The treatment and spillover effects can be point identified and consistently estimated if network degrees are bounded for all units. We also demonstrate the bias reduction property of our method if network degrees of some units are unbounded. Monte Carlo experiments and a naturalistic simulation on real-world network data are implemented to verify the finite-sample performance of our method. We also re-examine the spillover effects of home computer use on children's self-empowered learning.
