Modern Difference-in-Differences: New Problems, New Solutions

  • Working knowledge of linear regression and basic familiarity with panel data concepts (fixed effects, clustering)
  • Prior experience with Stata is expected
  • No prior exposure to the new DiD literature is assumed — the workshop builds from the ground up

SESSION I: SIMPLE DID DESIGNS

  • The 2×2 design
  • 2×T event studies
  • Parallel trends
  • Interpreting ATT parameters as estimands
  • Clustering and standard errors

 

SESSION II: VIOLATIONS OF PARALLEL TRENDS

  • Covariates
  • Triple differences
  • Compositional changes over time
  • Addressing weak overlap

 

SESSION III: DIFFERENTIAL TIMING

  • Two-way fixed effects problems
  • Goodman-Bacon decomposition,  Callaway and Sant’Anna, Sun and Abraham, Borusyak et al., Wooldridge
  • Imputation vs. weighting estimators

 

SESSION IV: SENSITIVITY ANALYSIS

  • Bounding parallel trends violations
  • Sensitivity of results across packages and languages

 

SESSION V: CONTINUOUS DID AND DOSAGE DESIGNS

  • Extending difference-in-differences to continuous treatments and dosage frameworks

 

SESSION VI: A MODEST SUGGESTION OF CHECKS

  • Walk-throughs using several empirical examples, all in Stata
  • Practical guidance on reporting and diagnostics

This Workshop is being offered on the second day of the Italian Stata Users Conference that will take place in Milan, on the 17th-18th September 2026.
