I’ll keep as my pinned Tweet links to the threads my co-authors and I wrote on our papers: 1) Ferman and Pinto: Inference in DID with few treated twitter.com/bruno_ferman/s… @cristinepinto16
Bruno Ferman@bruno_ferman

💡 Inference in difference-in-differences with few treated clusters 💡 Ferman and Pinto (2019) was published a couple of years ago, when I was not on Twitter. But I think it’s not too late to write a thread on it. 1/12

Obrigado ao @PossebomVitor e ao @bruno_ferman por terem me apoiado e recebido com muita atenção numa trajetória acadêmica não muito tradicional. Obrigado ao @thaleszp por ter me ensinado que pesquisa de qualquer tipo ou tema se faz com muito rigor e curiosidade.

"This study estimates the carbon-efficient forest cover in the Brazilian Amazon. A $10/ton carbon tax could preserve 95% of the efficient carbon stock, avoiding 42B tons of CO2 & yielding $1.6T in welfare gains." New paper from @AraujoCRRafael, @_FranciscoCosta & Sant'Anna: 👇

Are you unsure about how to conduct inference when you only have a few treated units? @lafalvarez, @bruno_ferman, and Wüthrich will help you! Check their easy-to-read survey paper to learn how to use many state-of-the-art tools in this setting.

15/ Applied folks: we hope this serves as a warning that standard inference may fail with few treated units + guidance on choosing alternatives. Econometricians: we wanted to provide a state-of-the-art overview — and a call for new methods based on alternative assumptions!

4/ Extreme case: you have only 1 treated and N₀ controls. The true variance is σ₁² + σ₀²/N₀. But with only one treated, you just don’t have enough info to estimate σ₁² using only 1 treated! Robust SEs simply set σ̂₁² = 0! 😵‍💫 σ₁²: var of treated σ₀²: var of control
