🚀 Here we go!

Our new paper with @pedrohcgs just dropped. We unpack DDD designs to better understand what's going on— Thread below has the scoop. 👇🧵

🚨New paper alert🚨

My paper with @marcelortizv on "Better Understanding Triple Differences Estimators" is finally out.

📰 https://t.co/3eJRn7m5JU

Main msg: Nuances in DDD designs challenge the practice of generally viewing DDD as the diff btw two DiDs. We can do better!

We have a different post today
I've had to defend using ML in my own work, so I decided to write down my case for it - for students, colleagues, skeptics, and for anyone who believes we share the goal of solving problems with the best tools available :)

The nicest way to finish the week is with a new post :)
New tools for empiricists: better DDD estimators, distributional DiD with staggered timing, using causal diagrams to assess parallel trends, and how counterfactuals work differently in CI vs XAI https://t.co/5v5bNOyo55
