基于网络数据的部分线性回归模型的辨识与估计

Identification and Estimation of a Partially Linear Regression Model using Network Data

Eric Auerbach

摘要:

我研究了一个回归模型,其中一个协变量是网络中链接形成的潜在驱动因素的未知函数。而不是指定和适合参数网络形成模型,我介绍了一种新的方法,基于匹配对代理与类似列的平方邻接矩阵,该方法背后的直觉是,对于大类网络形成模型,平方邻接矩阵的列表征所有可识别的关于个人链接行为的信息。在本文中,我描述了模型,形式化这种直觉,并提供了一致的回归模型的参数估计。Auerbach(2021)考虑了推理和网络同伴效应的应用。

英文摘要:

I study a regression model in which one covariate is an unknown function of a latent driver of link formation in a network. Rather than specify and fit a parametric network formation model, I introduce a new method based on matching pairs of agents with similar columns of the squared adjacency matrix, the ijth entry of which contains the number of other agents linked to both agents i and j. The intuition behind this approach is that for a large class of network formation models the columns of the squared adjacency matrix characterize all of the identifiable information about individual linking behavior. In this paper, I describe the model, formalize this intuition, and provide consistent estimators for the parameters of the regression model. Auerbach (2021) considers inference and an application to network peer effects.
