Superstar economics (Rosen, 1981) explains why a tiny minority of performers, executives, and athletes earn the lion's share of compensation — small ability differences + scale technology = winner-take-most markets.
In a world where the best soprano can sing live to 2,000 people, the income gap between her and the second-best is small. In a world where she can stream to 200 million on Spotify, the gap explodes. The same logic explains why Taylor Swift's Eras Tour earns more than the next 50 tours combined, why CEO pay scales with company size, and why a tiny number of YouTube creators capture the platform's revenue.
