INSIGHT

Why Winners Overpay

  • The winner's curse arises because winners are systematically the most optimistic bidders and thus overpay.
  • This pattern appears in high-stakes field settings like oil auctions, not just low-stakes labs.

Biases Persist Even Under High Stakes

  • Many classic lab anomalies also show up in professional, high-stakes settings when researchers use better data.
  • Learning reduces biases only slowly, so professional decision-makers still display robust behavioral errors.
INSIGHT

Strategic Misunderstanding Explains Curses

  • The winner's curse doesn't violate expected-utility axioms but reflects misunderstandings about others' strategic behavior.
  • Cursed-equilibrium and cognitive-hierarchy models formalize this failure of theory-of-mind in strategic settings.
