If you've been wondering how to explore the informational content of your Parallel Trends assumptions to get the most precise DiD and ES estimator possible, we have some good news for you!! Our new DiD paper is out: arxiv.org/abs/2506.17729 😎Get along for a brief overview😎 1/

Here we go for another week full of GenAI, a DiD seminar, and a DiD workshop! For those attending PolMeth at @EmoryUniversity: looking forward to connecting!
Econometric analysis typically ignores researcher incentives. This article frames experimental data analysis as a mechanism-design problem, showing how unbiased estimation and sample splitting can resolve conflicts of interest. econometricsociety.org/publications/e…
What an fun and productive week! Co-teaching with @jmwooldridge and having the help of @SofiaTsarsi and @ianLal with the labs was just awesome!

Thank you, @BeatrizGietner, for covering our paper!!!
We have a new post 🙃 Three recent DiD papers, one shared goal: better estimates in messy settings ☑️DiD that hits efficiency bounds ☑️Synthetic DiD that mimics an oracle ☑️TWFE vs. the new wave 👉substacktools.com/sharex/l34vE6Hs
It’s a real pleasure team teaching a course with @pedrohcgs. Many are referring to us as “Fire and Ice.”
