Abstract

The sdid command implements the synthetic difference-in-differences method of Arkhangelsky et al. (AER, 2021) for Stata. The program generates the ATT estimate derived in Arkhangelsky et al. (2021), and conducts inference following their bootstrap, placebo, or jackknife methods. The command allows for multiple treatment dates and multiple treatment units directly, as well as cases with only a single treatment unit. As well as estimation and inference, the sdid command includes a number of graphical output options to summarize the synthetic difference-in-differences estimator.
