Abstract: multisynth extends the synthetic-control method of Abadie, Diamond, and Hainmüller (2010) to panel settings with multiple treated units and staggered treatment timing. The synthetic-control idea — finding a convex combination of untreated units that reproduces the treated unit's pre-treatment outcome path — is applied independently to each treated unit. Treated units are identified by treated()==1; the variable post() defines the unit-specific split between pre-treatment and post-treatment observations, so units need not share a common treatment date.

Language: Stata
Requires: Stata version 16
