I just moved to the Bay Area and am excited to visit Stanford for the 2025-2026 academic year. If you're around and want to talk AI/economics or grab a Philz coffee, please reach out!

Looking forward to the NBER SI Thursday metrics session next week where we will be presenting work on remote sensed outcomes with Rahul Singh and Ashesh Rambachan. Here is the program www.nber.org/conferences/... and preview dviviano.github.io/projects/pre... Drop by if you are around!

Can an AI model predict perfectly and still have a terrible world model? What would that even mean? Our new ICML paper (poster tomorrow!) formalizes these questions. One result tells the story: A transformer trained on 10M solar systems nails planetary orbits. But it botches gravitational laws 🧵

Enjoying a great day with #EctJ events at #RES2025. Stéphane Bonhomme gave the Sargan Lecture on dynamic feedback & unobserved heterogeneity in panel data. In EctJ’s Special Session, @asheshrambachan.bsky.social & Tim Christensen discussed challenges arising from using AI/LLMs in economic research
