Abstract

We consider a model in which an outcome depends on two discrete treatment variables, where one treatment is given before the other. We formulate a three-equation triangular system with weak separability conditions. Without assuming assignment is random, we establish the identification of treatment effects using two-step matching. We allow for the treatment variables to be nonbinary and do not appeal to an identification-at-infinity argument.
