Simple Difference-in-Differences Estimation in Fixed-T Panels
The present paper proposes a new treatment effects estimator that is valid when the number of time periods is small, and the parallel trends condition holds conditional on covariates and unobserved heterogeneity in the form of interactive fixed effects.
Difference-in-Differences with Geocoded Microdata
I introduce intuitive assumptions needed to identify the average treatment effect among the affected units and illustrates pitfalls that occur when these assumptions fail.
Geographic Difference-in-Discontinuities
A recent econometric literature has critiqued the use of regression discontinuities where administrative borders serves as the 'cutoff'.
{did2s}: Two-Stage Difference-in-Differences
The article provides an approachable review of the underlying econometric theory and introduces the syntax for the function did2s.
