Identification and Estimation of Causal Peer Effects Using Double Negative Controls for Unmeasured Network Confounding

  title={Identification and Estimation of Causal Peer Effects Using Double Negative Controls for Unmeasured Network Confounding},
  author={Naoki Egami and Eric J. Tchetgen Tchetgen},
Scientists have been interested in estimating causal peer effects to understand how people’s behaviors are affected by their network peers. However, it is well known that identification and estimation of causal peer effects are challenging in observational studies for two reasons. The first is the identification challenge due to unmeasured network confounding, for example, homophily bias and contextual confounding. The second issue is network dependence of observations, which one must take into…

Identification of Causal Diffusion Effects Using Placebo Outcomes Under Structural Stationarity∗

Social and biomedical scientists have long been interested in the process through which ideas and behaviors diffuse. In this article, we study an urgent social problem, the spatial diffusion of hate

Using Embeddings for Causal Estimation of Peer Influence in Social Networks

The main aim is to nonparametrically formalize the causal effect in a way that accounts for homophily, and to show how embedding methods can be used to identify and estimate this effect.

Proximal Causal Inference for Marginal Counterfactual Survival Curves

Contrasting marginal counterfactual survival curves across treatment arms is an effective and popular approach for inferring the causal effect of an intervention on a right-censored time-to-event

Treatment Effect Estimation from Observational Network Data using Augmented Inverse Probability Weighting and Machine Learning

Causal inference methods for treatment effect estimation usually assume independent experimental units. However, this assumption is often questionable because experimental units may interact. We

Double Negative Control Inference in Test-Negative Design Studies of Vaccine Effectiveness

A novel approach is presented to identify and estimate vaccine effectiveness in the target population by carefully leveraging a pair of negative control exposure and outcome variables to account for potential hidden bias in TND studies.



Estimating Peer Effects in Longitudinal Dyadic Data Using Instrumental Variables

This paper investigates how causal peer effects of traits and behaviors can be identified using genes (or other structurally isomorphic variables) as instrumental variables (IV) in a large set of data generating models with homophily and confounding and shows that IV identification of peer effects remains possible even under multiple complications often regarded as lethal.

Identification of Causal Diffusion Effects Under Structural Stationarity.

This work develops a statistical test that can detect a wide range of biases and proposes a difference-in-differences style estimator that can directly correct biases under an additional parametric assumption, and studies the spatial diffusion of hate crimes against refugees in Germany.

Multiply robust causal inference with double‐negative control adjustment for categorical unmeasured confounding

This work establishes non-parametric identification of the ATE under weaker conditions in the case of categorical unmeasured confounding and negative control variables, and provides a general semiparametric framework for obtaining inferences about the AtE while leveraging information about a possibly large number of measured covariates.

A Confounding Bridge Approach for Double Negative Control Inference on Causal Effects (Supplement and Sample Codes are included)

Unmeasured confounding is a key challenge for causal inference. Negative control variables are widely available in observational studies. A negative control outcome is associated with the confounder

Bias and High-Dimensional Adjustment in Observational Studies of Peer Effects

It is shown that high-dimensional adjustment of a nonexperimental control group using propensity score models produces estimates of peer effects statistically indistinguishable from those using a large randomized experiment, which demonstrates how detailed records of behavior can improve studies of social influence, information diffusion, and imitation.

Regression‐based negative control of homophily in dyadic peer effect analysis

A regression-based approach is developed which leverages a negative control exposure for identification and estimation of contagion effects on additive or multiplicative scales, in the presence of homophily bias to evaluate the peer effect of obesity in Framingham Offspring Study.

Identification and Estimation of Treatment and Interference Effects in Observational Studies on Networks

An extended unconfoundedness assumption that accounts for interference is proposed, and new covariate-adjustment methods are developed that lead to valid estimates of treatment and interference effects in observational studies on networks.

An Introduction to Proximal Causal Learning

A formal potential outcome framework for proximal causal learning is introduced, which while explicitly acknowledging covariate measurements as imperfect proxies of confounding mechanisms, offers an opportunity to learn about causal effects in settings where exchangeability on the basis of measured covariates fails.

Estimating average causal effects under general interference, with application to a social network experiment

This paper develops the case of estimating average unit-level causal effects from a randomized experiment with interference of arbitrary but known form and provides randomization-based variance estimators that account for the complex clustering that can occur when interference is present.
