The paper builds a small simulated economy with 100 language‑model “workers” and one language‑model “planner”, then lets that planner tweak 7 income‑tax brackets every 128 steps until the society’s average happiness ends up about 90% higher than under the current US code. In

Great honor for me to receive the DeLeon senior scientist award at the international Alzheimer's meeting. I share it with the amazing former PhD student Zhijian Yang who did this work (lnkd.in/esHmimvK), co-supervisors Junhao (Hao) Wen and Ilya Nasrallah, and collaborators.
