Episode notes
A Course That Shaped A Career
- Judd recounts taking Alvin Roth's PhD-level course as an undergrad, which shaped his interest in market design.
- That experience led him to return to Harvard for a PhD and pursue market-design research.
Hidden Markets Aren't Driven By Price
- Many markets clear by price, but many important allocations deliberately avoid price mechanisms.
- Hidden markets allocate by rules other than money and require different strategic thinking.
Why Sellers Avoid Market-Clearing Prices
- Sellers often keep prices below market-clearing to preserve fan access, reputational benefits, or social proof.
- Low posted prices create excess demand that can increase future attention and long-term value.
