Summary

Kevin Cold Iron speaks with economist Alex Imas about the updated edition of The Winner’s Curse. They cover mental accounting, savings and stimulus design, nudges versus incentives, and the winner’s curse in auctions and IPOs. The discussion also examines law-of-one-price violations, limits to arbitrage, and why mispricings persist. Market implications include long-run stock market participation, caution on arbitrage trades, and hidden beta in market-neutral strategies.

  • Alex Imas explains mental accounting and how people treat money differently by source.
  • The winner’s curse explains overbidding in common-value auctions like oil leases.
  • Law-of-one-price violations appear in historical cases such as 3M/Palm and CUBA.
  • Limits to arbitrage and embedded beta make apparent riskless arbitrage dangerous.
  • Stock market participation remains low despite long-run return advantages.
  • AI-driven labor displacement raises policy questions about broader capital ownership.
  • Behavioral economics remains difficult to integrate into standard economics textbooks.

More people should own stocks long-term.
Given the long-run returns of the stock market, far more people should have their money invested in stocks rather than parked in bank deposits; the main barrier is often attention and understanding, so starting people with an account can increase stock market participation.

Arbitrage opportunities are not free lunches.
Apparent arbitrage opportunities and law-of-one-price violations are not free lunches because limits to arbitrage—including risk, liquidity and funding constraints, market irrationality, and transactional barriers—can make them unsafe and allow mispricings to persist.
Arbitrage trades HIGH

Market-neutral arbitrage trades hide directional beta.
Market-neutral arbitrage trades often require significant leverage and depend on funding; lenders can close positions when markets fall, so these trades contain embedded beta and become directional at the worst possible time.
Market-neutral arbitrage trades HIGH
