Randomization Tests in Randomized Saturation Designs
Jizhou Liu, Azeem M. Shaikh, Liang Zhong
Randomized saturation designs are widely used to study spillover effects in clustered populations. In these designs, clusters are first assigned to treatment saturation levels, and…
Randomization Tests in Switchback Experiments
Jizhou Liu, Liang Zhong
Switchback experiments assign an experimental unit, such as a market or a platform, to treatment or control over successive blocks of time. Inference can be challenging because the…
Auto-Doubly Robust Estimation of Causal Effects on a Network
Jizhou Liu, Dake Zhang, Eric J. Tchetgen Tchetgen
This paper develops new methods for causal inference in observational studies on a single large network of interconnected units, addressing two key challenges: long-range dependenc…
Randomization Inference in Two-Sided Market Experiments
Jizhou Liu, Azeem M. Shaikh, Panos Toulis
Randomized experiments are increasingly employed in two-sided markets, such as buyer--seller platforms, to evaluate the effects of marketplace interventions. These experiments must…
Proximal Causal Inference for Synthetic Control with Surrogates
Jizhou Liu, Eric J. Tchetgen Tchetgen, Carlos Varjão
The synthetic control method (SCM) has become a popular tool for estimating causal effects in policy evaluation, where a single treated unit is observed, and a heterogeneous set of…
Semiparametric Estimation of Treatment Effects in Observational Studies with Heterogeneous Partial Interference
Zhaonan Qu, Ruoxuan Xiong, Jizhou Liu +1
In many observational studies in social science and medicine, subjects or units are connected, and one unit's treatment and attributes may affect another's treatment and outcome, v…
