Episode notes
Winner's Curse From Oil Bids
- The Winner's Curse shows auction winners often overpay because optimistic estimates win.
- Atlantic Richfield engineers noticed won lots had less oil than predicted, revealing structural bidding risk.
Limited Iteration Shapes Strategic Play
- Strategic reasoning often stops after a few steps, not reaching Nash equilibrium.
- In beauty-contest games people partially iterate reasoning, producing middling, not extreme, outcomes.
Game Shows As Field Experiments
- Thaler used high-stakes game shows like Golden Balls to test cooperation outside the lab.
- Real contestants show similar but slightly higher cooperation than low-stakes lab subjects.
