The treatment effect, the cross difference, and the interaction term in nonlinear “difference-in-differences” models

Patrick Puhani

Economics Letters, 2012, vol. 115, issue 1, 85-87

Abstract: In any nonlinear “difference-in-differences” model with strictly monotonic transformation function, the treatment effect is the cross difference of the observed outcome minus the cross difference of the potential non-treatment outcome, which equals the incremental effect of the interaction term coefficient.
