In this article we propose several modeling choices to extend propensity score analysis to clustered data. We describe different possible model specifications for estimation of the propensity score: single-level model, fixed effects model, and two random effects models. We also consider both conditioning within clusters and conditioning across clusters. We examine the underlying assumptions of these modeling choices and the type of randomized experiment approximated by each approach. Using a… CONTINUE READING
