Webfrom papers that analyzed settings with heterogeneous treatment effects and variation in the treatment timing, and/or (ii) we can allow for uniform confidence bands when considering event-study plots. Conley and Taber (2011) discuss in their Section III.A the possibility of extending their approach to heterogeneous treatment effects. WebAug 6, 2024 · With multiple periods and variation in treatment timing, TWFE: Is sensitive to treatment effect dynamics (this is similar to the binary treatment case and occurs because already-treated units sometimes serve as controls for late-treated units in periods where the already-treated units treatment status does not change over time). This can …
WebIn this article, we consider identification, estimation, and inference procedures for treatment effect parameters using Difference-in-Differences (DiD) with (i) multiple time periods, (ii) variation in treatment timing, and (iii) when the “parallel trends assumption” holds potentially only after conditioning on observed covariates. WebThis vignette briefly discusses the emerging literature on DiD with multiple time periods – both issues with standard approaches as well as remedies for these potential problems. …
Webvariation in treatment timing would make the case for using TWFE regressions even weaker, as it would introduce additional issues particularly related to using already treated units as com-parison units (which can lead to negative weights on underlying treatment effect parameters), as all three papers mentioned above imply. WebJun 2, 2024 · So the variation comes from comparing treated firms with untreated firms, but also in the timing impact of the laws. It actually exploits all possible two-group/two-period (2x2) comparisons present in your data. Now it's important to note that the causal estimand is plausibly unbiased if we assume constant treatment effects.

WebThe canonical difference-in-differences (DD) estimator contains two time periods, ”pre” and ”post”, and two groups, ”treatment” and ”control”. Most DD applications, however, exploit variation across groups of units that receive treatment at different times.
