uh, whut?Our empirical identification strategy relies on our binary variable for major tax cuts for the
rich, which permits us to apply a nonparametric generalization of the difference-in-differences
indicator for panel data analysis (Imai et al., 2020). The technique uses Mahalanobis
matching to compare treated and untreated units that have similar treatment histories and
pre-treatment covariate trajectories.
