Identification and Estimation of Spillover Effects in Randomized Experiments

  title={Identification and Estimation of Spillover Effects in Randomized Experiments},
  author={Gonzalo V{\'a}zquez-Bar{\'e}},
  journal={arXiv: Econometrics},
I study identification, estimation and inference for spillover effects in experiments where units' outcomes may depend on the treatment assignments of other units within a group. I show that the commonly-used linear-in-means (LIM) regression identifies a weighted sum of spillover effects with some negative weights, and that the difference in means between treated and controls identifies a combination of direct and spillover effects entering with different signs. I propose nonparametric…

Spillovers, Homophily, and Selection into Treatment: The Network Propensity Score∗
Propensity score matching is often used to estimate treatment effects when there is selection on observables; however, it fails to identify causal effects when one person’s treatment affects
Difference-in-Differences Estimation with Spatial Spillovers
Empirical work often uses treatment assigned following geographic boundaries. When the effects of treatment cross over borders, classical difference-in-differences estimation produces biased
Causal Inference for Spatial Treatments
A framework, estimators, and inference procedures for the analysis of causal effects in a setting with spatial treatments are proposed and a comparison between individuals near realized treatment locations and individuals near unrealized candidate locations is motivated.
Bounds for Treatment Effects in the Presence of Anticipatory Behavior
It is often the case in program evaluation that units will often anticipate the implementation of a new policy before it occurs. Such anticipatory behavior can lead to units’ outcomes becoming
Spillovers of Program Benefits with Mismeasured Networks
A novel method to nonparametrically point-identify the treatment and spillover effects, when two network observations are available, is proposed and applied to study the spillovers of an insurance information program on the insurance adoption decisions.
Efficient Treatment Effect Estimation in Observational Studies under Heterogeneous Partial Interference
In many observational studies in social science and medical applications, subjects or individuals are connected, and one unit’s treatment and attributes may affect another unit’s treatment and
Policy choice in experiments with unknown interference
An adaptive randomization procedure to estimate welfare-maximizing individual treatment allocation rules valid under unobserved interference is introduced and the asymptotic properties of the estimators and small sample regret guarantees of the estimated policy are discussed.
Handling Spillover Effects in Empirical Research
Despite their importance, the discussion of spillover effects in empirical research often misses the rigor dedicated to endogeneity concerns. We analyze a broad set of workhorse models of firm
Estimating General Equilibrium Spillovers of Large-Scale Shocks
Researchers use (quasi-)experimental methods to estimate how shocks affect directly treated firms and households. Such methods typically do not account for general equilibrium spillover effects. I
Handling Spillover Effects in Empirical Research: An Application using Credit Supply Shocks
Despite their importance, the discussion of spillover effects in empirical research misses the rigor dedicated to endogeneity concerns. We show that i) even with random treatment, spillovers lead to


Estimating the Structure of Social Interactions Using Panel Data
I consider settings where outcomes depend on own characteristics and on the characteristics of other individuals in the sample. I propose a method to identify individuals generating spillovers and

Multivalued Treatments and Decomposition Analysis: An Application to the WIA Program
This paper provides a general estimation and inference framework to study how different levels of program participation affect participants' outcomes. We decompose differences in the outcome
Large Sample Randomization Inference of Causal Effects in the Presence of Interference
This article considers inference about effects when the population consists of groups of individuals where interference is possible within groups but not between groups, and considers the effects of cholera vaccination and an intervention to encourage voting.

Detecting Spillover Effects: Design and Analysis of Multilevel Experiments
Interpersonal communication presents a methodological challenge and a research opportunity for researchers involved in field experiments. The challenge is that communication among subjects blurs the
Toward Causal Inference With Interference
This article considers a population of groups of individuals where interference is possible between individuals within the same group, and proposes estimands for direct, indirect, total, and overall causal effects of treatment strategies in this setting.
Design and Analysis of Experiments in Networks: Reducing Bias from Interference
This work evaluates methods for designing and analyzing randomized experiments under minimal, realistic assumptions compatible with broad interference, finding substantial bias reductions and, despite a bias–variance tradeoff, error reductions.
