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…
