🚨Major new version🚨
Algorithmic Collusion by Large Language Models
Joint w/@sarafish_ & @RanShorrer

Excited to share my JMP: "The Messenger Matters"
Does it matter who communicates policies to the public? Yes! The messenger impacts both the reach and influence of communication.
Using big data, an experiment, and theory, I show how. 🧵👇
