Episode notes
Use AI To Expand Not Replace Choice
- Preserve human agency when applying AI: enable personalization without subsuming choice.
- Use AI to expand fulfillment and choice, not to surrender the use of one's paycheck or personal decisions.
Affiliate Models Favor Low-Price Goods
- Affiliate recommendation systems lack advertisers' private value signals and thus optimize for conversion probability over total value.
- Without bids, models favor low-priced, broadly appealing items and compress product differentiation.
Ad Auctions Encode Private Value
- Advertising auctions inject advertiser-specific bids that represent private value, enabling ranking by expected monetization rather than mere conversion likelihood.
- This aligns platform revenue with total surplus and supports heterogeneous product surfacing.
