Episode notes
Hidden Markets Favor Nonprice Rules
- Hidden markets allocate scarce goods when price is excluded, creating races won by the tech-savvy or well-resourced.
- These markets often produce inefficient or inequitable outcomes like ticket bots beating normal buyers.
Rock-Paper-Scissors Teaches Market Strategy
- Judd taught his four-year-old daughter rock-paper-scissors to illustrate learning market rules and strategy.
- She played scissors every time and lost, showing knowing rules alone isn't enough without strategy.
Pick Gold Or Settle For Silver Strategically
- Decide whether to 'go for gold' or 'settle for silver' when competing in first-come races like reservations.
- Choose a less-contested option if the marginal value of the top choice is small to increase success chances.
