Welcome to Zurich!!

A fantastic conference honoring a great economist and friend. Albert’s T-shirt in the picture, co-designed by Jordi Galí and OpenAI, features a Ghibli-style illustration of Marcet and Sargent pondering how agents form expectations.

Ending this semester’s macro seminar series at UNC with an absolute highlight: Jonathan Payne @princetonecon.bsky.social taught us his brilliant joint work with @yuchengyang1993.bsky.social and Adam Rebei on *Deep Learning for Search and Matching Models*

Wrapped up an exciting workshop on cutting-edge methods in macro & trade! Great talks using deep learning, combinatorial optimization, LLMs, and beyond to study tariffs, tech wars, sanctions, monetary/fiscal/climate/financial policies, and many other important questions!

Very excited to co-host the 𝐖𝐨𝐫𝐤𝐬𝐡𝐨𝐩 𝐨𝐧 𝐀𝐈 𝐚𝐧𝐝 𝐍𝐞𝐰 𝐌𝐞𝐭𝐡𝐨𝐝𝐬 𝐢𝐧 𝐌𝐚𝐜𝐫𝐨 𝐚𝐧𝐝 𝐓𝐫𝐚𝐝𝐞 in Zurich this week! Looking forward to learning from leading economists pushing the frontier of new methods to tackle big questions of our time. @kubler.bsky.social @compsimon.bsky.social @leonardo-melosi.bsky.social
