Distributional Treatment Effects of Content Promotion: Evidence from an ABEMA Field Experiment

Shota Yasui, Tatsushi Oka, Undral Byambadalai +1

We examine the impact of top-of-screen promotions on viewing time at ABEMA, a leading video streaming platform in Japan. To this end, we conduct a large-scale randomized controlled…

Beyond the Average: Distributional Causal Inference under Imperfect Compliance

Undral Byambadalai, Tomu Hirata, Tatsushi Oka +1

We study the estimation of distributional treatment effects in randomized experiments with imperfect compliance. When participants do not adhere to their assigned treatments, we le…

Efficient and Scalable Estimation of Distributional Treatment Effects with Multi-Task Neural Networks

Tomu Hirata, Undral Byambadalai, Tatsushi Oka +2

We propose a novel multi-task neural network approach for estimating distributional treatment effects (DTE) in randomized experiments. While DTE provides more granular insights int…
