Nonparametric Causal Decomposition of Group Disparities
The Annals of Applied Statistics (2025) Authors: Ang Yu, Felix Elwert Abstract: We introduce a new nonparametric causal decomposition approach that identifies the mechanisms by which a treatment variable contributes to a group-based outcome disparity. Our approach distinguishes three mechanisms: group differences in: (1) treatment prevalence, (2) average treatment effects, and (3) selection into treatment …
