Series number :
- Difference in differences •
- staggered difference-in-differences designs •
- generalized difference-in-differences •
- dynamic treatment effects
Difference-in-differences analysis with staggered treatment timing is frequently used to assess the impact of policy changes on corporate outcomes in academic research. However, recent advances in econometric theory show that such designs are likely to be biased in the presence of treatment effect heterogeneity.
