are homogeneous. when treatment effects are heterogeneous across units, ols over-weights units with more variance in treatment status in order to achieve a more precise estimate of the treatment effect. hence, units that are treated near the middle of the evaluation window receive relatively more weight

re-weighting is required. second, and more troublingly, dd estimates are biased when treatment effects change over time within unit. intuitively, this occurs because already treated units serve as controls in some of the two-by-two dds underlying the weighted average. when treatment effects are not constant...
