Economics has a lamppost problem: we study what our data already measure. Unstructured data and AI will change that and that will be transformative.

I'm excited to give the NBER Methods Lecture with @MelissaLDell this Thursday: "Estimation and Inference with AI-Generated Data."

Thread on a new paper about world models with @petergchang, @keyonV, and @m_sendhil!

Can an AI model predict perfectly and still have a terrible world model?

What would that even mean?

Our new ICML paper formalizes these questions

One result tells the story: A transformer trained on 10M solar systems nails planetary orbits. But it botches gravitational laws 🧵
