Wrapped up #icRS2026 in Cebu.
Grateful to have presented my ongoing work and exchanged ideas with scholars working on resource sustainability, environmental governance, and policy design.
Leaving with thoughtful feedback, new questions, and fresh motivation.

One of my favorite papers in recent years included this diagram.
It shows the impact of controlling for three different types of variables: confounders, colliders, and mediators.
With confounders, control is good. With the others, you ruin your result by controlling.
#QJE Aug 2025, #3, “Structural Estimation Under Misspecification: Theory and Implications for Practice,” by Andrews, Barahona (@NanoBarahona), Gentzkow, Rambachan (@asheshrambachan), and Shapiro: https://t.co/Xx6WmD8qdT
This looks a must read for those interested in triple differences (DDD) designs.
It shows that the standard way many estimate DDD is wrong.
It shows why and gives you tools that work with covariates and staggered adoption.
Bonus: free R package.

An observation: We are getting more and more theory paper but little on implementation. Hopefully some new packages will also be made available soon.
