Webinar: Heterogenous Difference in Differences

About the Webinar

The last years have seen an explosion in the difference-in-differences (DID) literature. We have moved from assuming treatment effects did not change over group or time to assuming treatment effects change over group and time. We have embraced heterogeneity.

Stata 18 introduced two commands (each with four estimators) to fit heterogeneous (DID) models: hdidregress for repeated cross-sectional data and xthdidregress for panel/longitudinal data. In this webinar, we briefly introduce the theory behind both estimators and then show how to fit heterogeneous DID models using the new commands. We also demonstrate postestimation tools to aggregate and visualise heterogeneous treatment effects and perform diagnostic tests.
 

Join us for this one-hour webinar, and learn how you can make your interactions with Stata more efficient and more effective.
