WebThe did_multiplegt command by Chaisemartin and D’Haultfœuille (henceforth CD) is probably one of the most flexible DiD estimators currently available. A key reason is that it allows for treatment switching (units can move in and out of treatment status) in addition to time-varying, heterogeneous treatment effects. In principle, you have access to data for two groups. Group 0 or control group, and group 1 or treated group. In addition, you observe the outcomes on this two groups across two periods (ideally the same periods), a T0 or pre-treatment when neither of the groups were treated, and T1 or post-treatment where the … See more Because we are unable to observe all possible scenarios, one of the most popular alternatives has been the use of Difference-in-difference approach. So lets return to the previous example. Assume for a moment, that … See more If you have follow the literature on DID, you are probably aware that TWFE is not DID, specially if you are dealing with multiple periods, with … See more One of questions Pedro has been asked, and I wonder myself, when thinking about covariates, is how to use them for adjusting for the differences described above. His answer, always use pre-treatment … See more A better question may be, why do we need controls? or what do we need to control for?. One answer that I like is that we need controls to minimize … See more
