A Unified Framework for Transparent Quasi-Experimental Research
This paper develops a framework that allows researchers to describe a wide class of quasi-experimental treatment effect estimates using direct analogs of the features that make a randomized controlled trial transparent. The outcome weight measures how much each observation’s outcome contributes to an estimate, and its sign defines effective treatment and control groups. We show that estimates take a Wald form, equal to the weighted outcome difference between these groups divided by an effective first stage that quantifies the identifying treatment contrast. Our framework also allows ...
