Ranking Treatment Saturations: Regret Bounds and Experimental Design
Seungjin Han, Julius Owusu, Youngki Shin
We study the statistical decision problem of ranking treatment saturations, the treated shares of a cluster. Planners need a ranking, not only the best saturation, when rollouts ar…
Causal Identification under Interference: The Role of Treatment Assignment Independence
Julius Owusu, Monika Avila Márquez
Applied researchers often use identification formulas derived under individualistic treatment response (ITR), which rules out interference, even when interference is plausible but…
A Nonparametric Test of Heterogeneous Treatment Effects under Interference
Julius Owusu
Statistical inference of heterogeneous treatment effects (HTEs) across predefined subgroups is challenging when units interact because treatment effects may vary by pre-treatment v…
Randomization Inference of Heterogeneous Treatment Effects under Network Interference
Julius Owusu
We develop randomization-based tests for heterogeneous treatment effects in the presence of network interference. Leveraging the exposure mapping framework, we study a broad class…
Statistical Treatment Rules under Social Interaction
Seungjin Han, Julius Owusu, Youngki Shin
In this paper we study treatment assignment rules in the presence of social interaction. We construct an analytical framework under the anonymous interaction assumption, where the…
csa2sls: A complete subset approach for many instruments using Stata
Seojeong Lee, Siha Lee, Julius Owusu +1
We develop a Stata command that implements the complete subset averaging two-stage least squares (CSA2SLS) estimator in Lee and Shin (2021). The CSA2SLS estimato…
