An incredible opportunity for the right person:

The Santa Fe Institute is seeking applications for full-time resident faculty positions at all academic levels

For me, this has been the best possible job ever.

For those who didn't make it to #ASSA2025: strongly recommend @sendhil.bsky.social's AEA distinguished lecture, available at www.aeaweb.org/webcasts/202... (starting at minute 16)!

Did OpenAI Just Solve Abstract Reasoning? OpenAI’s o3 model aces the "Abstraction and Reasoning Corpus" — but what does it mean?

Some of my thoughts on OpenAI's o3 and the ARC-AGI benchmark

Abstract of paper

Economic valuations fluctuate in ways empirical research cannot fully explain

What information are we missing? Economic theories emphasize the role of hard-to-quantify beliefs and perceptions

My job market paper develops algorithms + measurement to quantify perceptions of firms
