WebFeb 6, 2024 · I'm writing an event-study synthetic control estimator that's good in situations where more than one unit is treated at different times, or staggered implementation. While writing the syntax, I thought a lot about the recent advancements in difference-in-differences, namely the idea of how we might construct the donor pool/comparison group … WebThe difference between the synthetic control and the unit that it mimics is the treatment effect. To do this with linear regression, we will find the weight using OLS. We will minimise the square distance between the weighted average of the units in the donor pool and the treated unit for the pre-intervention period.
