Abstract: A framework for identifying concentration curves in a difference-in-differences setting is introduced. Building on the changes-in-changes and distributional difference-in-differences frameworks for identifying quantile treatment effects, the identification strategy is generalized to cases where the outcome variable is multidimensional, thereby allowing for nonparametric identification of bivariate objects such as concentration curves. Nonparametric estimators of counterfactual concentration curves are derived, and their asymptotic properties are investigated.
