Cambridge, MA - The biggest news around this city in recent weeks has been Jeremy Lin, the Harvard economics graduate, who has shocked the National Basketball Association by rising seemingly overnight from "nowhere" to become a genuine star, leading a losing New York Knicks team to an unlikely string of victories.
Lin's success is delicious, partly because it contradicts so many cultural prejudices about Asian-American athletes. Flabbergasted experts who overlooked Lin have been saying things like "he just didn't look the part". Lin's obvious integrity and graciousness has won him fans outside the sport as well. The whole world has taken note, with Lin being featured on the cover of Sports Illustrated for two consecutive issues. The NBA, which has been trying to build brand recognition and interest in China, is thrilled.
I confess to being a huge Lin fan. Indeed, my teenage son has been idolising Lin's skills and work ethic ever since Lin starred on the Harvard team. But, as an economist observing the public's seething anger over the "one percenters", or individuals with exceptionally high incomes, I also see a different, overlooked facet of the story.
What amazes me is the public's blasé acceptance of the salaries of sports stars, compared with its low regard for superstars of business and finance. Half of all NBA players' annual salaries exceed $2m, more than five times the threshold for the top one per cent of household incomes in the United States. Because long-time superstars such as Kobe Bryant earn upwards of $25m a year, the average annual NBA salary is more than $5m. Indeed, Lin's salary, at $800,000, is the NBA's "minimum wage" for a second-season player. Presumably, Lin will soon be earning much more, and fans will applaud.
Yet many of these same fans would almost surely argue that CEOs of Fortune 500 companies, whose median compensation is around $10m, are ridiculously overpaid. If a star basketball player reacts a split-second faster than his competitors, no one has a problem with his earning more for every game than five factory workers do in a year. But if, say, a financial trader or a corporate executive is paid a fortune for being a shade faster than competitors, the public suspects that he or she is undeserving or, worse, a thief.
Economists have long studied the economics of superstars in fields where a company can lever enormously the decisions of a small number of individuals, making them valuable in a way that someone who can, say, chop down trees like the legendary Paul Bunyan, is not. But the political economy of what levels of income differences countries will tolerate remains uncharted territory.
"Do fans tolerate outsize sports incomes because players are role models? Many certainly are, but not all high-paid sports celebrities are exemplary citizens."
Of course, there is a certain logic to the public's disdain for superstar compensation outside of professional sports and entertainment. This is especially the case in some areas of finance that are essentially zero-sum games, in which one person's gain is another's loss. There are other areas, such as technology, in which someone like Apple's late founder, Steve Jobs, arguably delivers real innovation and quality, rather than just employing lawyers and lobbyists to maintain a monopoly position.
As a basketball fan, I would not describe the sport as a zero-sum game, even though one team wins and one team loses. The best players have huge creative flair. But so do some "street ball" players who excel in slam-dunk theatrics; perhaps because they are not tall enough to compete, they make almost nothing.
Do fans tolerate outsize sports incomes because players are role models? Many certainly are, but not all high-paid sports celebrities are exemplary citizens. Michael Vick, a star quarterback in the US National Football League, served time in prison for running a vicious dog-fighting operation, and arrests of players on charges ranging from illegal possession of drugs and weapons to domestic battery have been a regular occurrence.
And, back on the field or court, serious infractions occur all the time. Think of Zinedine Zidane's infamous head butt in the 2006 football World Cup. In the NBA itself, a star player, Ron Artest, was suspended for the remainder of the 2004 season after going into the stands and brawling with heckling fans during a game. (Artest has now changed his name to Metta World Peace, perhaps in response.)
Moreover, sports teams surely lobby governments as aggressively as any big business. Professional sport is a legislated monopoly in many countries, with top teams extracting free stadia and other privileges from host cities. Indeed, Lin's story, it should be remembered, grew out of a huge labour dispute between the NBA's billionaire owners and its millionaire players over the division of the league's nearly $4bn annual revenues - more than many countries' national income.
As the late University of Chicago economist Sherwin Rosen postulated, globalisation and changing communication technologies have increasingly made the economics of superstars important in a variety of fields. That is certainly true in sports and entertainment, but it is also the case in business and finance.
I wish Lin a long and successful career as a superstar, though he will have already had a huge cultural impact even if his success proves meteoric. One can hope that, as Asian-Americans continue to break barriers in other arenas - they remain under-represented among corporate CEOs, for example - these rising superstars will be greeted with similar acclaim.
If the public is not happy about high superstar incomes, the obvious remedy is to improve the tax system, including for powerful sports-team owners, many of whom benefit from huge tax breaks in their day jobs. Who knows? With a more level playing field, superstars outside sports and entertainment might find themselves a bit better appreciated.
