Experimentation Under Non-stationary Interference
Su Jia, Peter Frazier, Nathan Kallus +1
We study the estimation of the ATE in randomized controlled trials under a dynamically evolving interference structure. This setting arises in applications such as ride-sharing, wh…

Clustered Switchback Designs for Experimentation Under Spatio-temporal Interference
Su Jia, Nathan Kallus, Christina Lee Yu
We consider experimentation in the presence of non-stationarity, inter-unit (spatial) interference, and carry-over effects (temporal interference), where we wish to estimate the gl…
