Dynamic Difference-in-Differences with Interference
AEA Papers and Proceedings
(pp. 58–63)
Abstract
Interference/spillover is a common concern in place-based policy evaluation. This paper develops a difference-in-differences framework that accounts for interference using panel data with multiple posttreatment periods and potentially staggered treatment adoption. I define causal parameters under interference, establish identification under a modified parallel trends assumption, and propose doubly robust estimators with valid inference. The method is illustrated through an empirical application.Citation
