Two-Way Fixed Effects Methods

This slide deck introduces how to work with the R code for the Callaway/Sant'Anna (2020) estimator.

• It also covers why difference-in-differences methods with staggered treament timing can be problematic, options for doing things differently, and how to use R (for novices). I prepared these slides for Chloe East's Metrics Discussion Group. It is designed for Stata users with limited to no R familiarity.
