A huge thank you to all the researchers whose excellent work this survey builds on. It's a privilege to synthesize and learn from this literature. Free access: authors.elsevier.com/a/1mp%7E-bmIcK… 8/8

The paper covers externalities, taxation, transit integration, labor regulation, and ride-hailing as an empirical laboratory. AVs will scale all of these challenges. The time to get policy right is now. 7/8

New survey paper in RSUE: "Ride-hailing and Urban Transportation: Evidence and Policy" Ride-hailing now accounts for 0.4% of US trips and 28 billion trips worldwide. AVs are about to make it much larger. The policy frameworks we set now will shape what comes next. 1/8

I’m hiring a predoc starting this summer. The focus is building AI workflows to improve research efficiency. More importantly, I value independent thinking and ambition. You do not need to fit into a narrow topic. If you’re interested in applied statistics, causal inference, or Chinese politics, broadly defined, plz apply. You can propose your own project --- I will support it. iriss.stanford.edu/predoc/2026-27…

This guy explains why walking in cities tends to feel more enjoyable than walking in the suburbs.

AI is changing economics, and --- as we just saw in Dwarkesh's interview with Dario --- AI researchers need to start thinking about economics too! The Center for Applied AI at UChicago will be hosting an AI & Economics Summer Institute to explore exactly this. We will bring together leading researchers with advanced graduate students in economics/AI/ML/NLP for an in-person program between Aug 6 - 11.

RT @jbsteinberg: I spend way too much time on social media debunking "economic slop" promulgated by lawyers pretending to be economists, so…

@MarkRober Did you know there is a mural of you in Hong Kong?

This paper in Management Science has been cited more than 6,000 times. Wall Street execs, top govt officials, and even a former U.S. Vice President have all referenced it. It’s fatally flawed, and the scholarly community refuses to do anything about it. statmodeling.stat.columbia.edu/2026/01/22/aki…

I met somebody at SF office hours in November who told me they had a dump of pre-AI Pinterest images. Unfortunately I forgot their handle and didn't get any other contact info.... Anybody know who this could be? cc @deepfates
