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 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…

On the Efficiency of Highly Stratified Experiments

Yuehao Bai, Jizhou Liu, Azeem M. Shaikh +1

This paper studies the use of highly stratified designs for the efficient estimation of a large class of treatment effect parameters that arise in the analysis of experiments. By a…

Inference After Ranking with Applications to Economic Mobility

Andreas Petrou-Zeniou, Azeem M. Shaikh

This paper considers the problem of inference after ranking. In our setting, we are interested in any population whose rank according to some random quantity, such as an estimated…

Inference in Cluster Randomized Trials with Matched Pairs

Yuehao Bai, Jizhou Liu, Azeem M. Shaikh +1

This paper studies inference in cluster randomized trials where treatment status is determined according to a "matched pairs" design. Here, by a cluster randomized experiment, we m…

Randomization Inference: Theory and Applications

David M. Ritzwoller, Joseph P. Romano, Azeem M. Shaikh

We review approaches to statistical inference based on randomization. Permutation tests are treated as an important special case. Under a certain group invariance property, referre…
