Synthetic Control Inference for Staggered Adoption

Understand

We introduce a synthetic control methodology to study policies with staggered adoption.

• Many policies, such as the board gender diversity policies, are replicated by other policy setters at different time frames.
• Our method estimates the dynamic average treatment effects on the treated using variation introduced by the staggered adoption of policies.
• Our method gives asymptotically unbiased estimators of many interesting quantities and delivers asymptotically valid inference.
