Rosen's theory
Rosen (1981) explained why, in some fields, a few people dominate the market and earn enormous incomes. He identified two conditions. First, for consumers, services from less talented sellers are poor substitutes for those of more talented sellers: just as ten operations by a mediocre surgeon cannot replace one by an outstanding surgeon, people will pay much more for someone slightly better. Second, technologies such as recording, broadcasting and publishing let one person serve a very large number of consumers at little additional cost. Combined, these conditions magnify small differences in talent into very large differences in earnings and concentrate the market among a few top sellers.
Alternative theories and related models
Adler (1985) argued that superstars can emerge even with no difference in talent. Because people want to consume stars that many others already know in order to talk and share with them, popularity snowballs toward whoever happens to get ahead. Salganik, Dodds and Watts (2006) reported in an online music market experiment that showing others' download counts increased inequality in popularity among songs and made hits harder to predict, demonstrating experimentally the role of social influence. Lazear and Rosen's (1981) tournament theory, meanwhile, explained that reward structures giving large prizes based on relative rank rather than absolute output can efficiently elicit effort, analyzing from another angle why rewards concentrate on winners.
Empirical research and inequality
Analyzing the U.S. rock concert market, Krueger (2005) reported that the share of revenue captured by top performers rose sharply, with factors such as technological change and declining record sales in the background. Gabaix and Landier (2008) argued that because the value a slightly more able chief executive creates grows with firm size, growth in large firms' market capitalization explains much of the surge in CEO pay. Kaplan and Rauh (2013) pointed to simultaneous growth in top incomes among athletes, entertainers, lawyers and financiers, arguing that technological change and larger markets broadly raised returns to top talent. The economics of superstars is used alongside the Matthew effect and network effects to understand why rewards concentrate among a few.
FAQ
- What is the economics of superstars in simple terms?
- It explains why someone who is only slightly better can earn far more. People want the best available, and technology lets one person reach huge audiences, so income concentrates among a few.
- How do Rosen's and Adler's superstar theories differ?
- Rosen argued that small talent differences are magnified into large income differences by technology and consumer preferences. Adler argued that even without talent differences, stars can emerge because people want to consume the same already-famous stars as others, so popularity snowballs.
