According to Frank and Cook, there are two types of economic systems. In the standard system a worker's rewards are proportional to the amount that he produces. So, if Rachel makes 10% more widgets than I do, and we're paid by the widget, then Rachel makes a 10% higher salary than I do. This is the system that almost all of economics is concerned with. A second system is a "winner take all" market. In this system, the person who is the most productive makes all of the profit (or in more complex versions, a disproportionate share of the profit), and the rest get nearly nothing. So, if Rachel is a 10% better poker player than I am, at the end of the day she has the entire pot of chips.
Frank and Cook argue two central theses: 1) The standard economic models do not work for winner take all markets and 2) Winner take all markets are increasingly prevalent in today's society. The conjunction of these points leads to a set of policy recommendations that differ from what comes from more prominent economic theory. I'm going to basically outline their logic below:
Before modern communications and transportation systems, if there were a great singer in Los Angeles, nobody in New York could hear her sing. And so there was a need for singers in both cities, as well as every other city in the country. And so singers around the country could make a modest living. But in today's economy, if the best singer in the country is in LA, then because of CD stores and radio and the internet, everybody in the country can listen to that one singer. If that LA singer is 10% better than her rivals (or even 1% better), then everybody will choose to buy her CDs as opposed to her rivals' CDs, and with an expanded audience she will make a tremendous fortune. Meanwhile, all the other singers who are losing their audience to the one LA singers will earn a lot less. Thus, we have moved from a standard market to a winner take all market.
Frank and Cook argue that while this is most evident in domains like sports and arts, the shift is occurring across all areas of society. A corporation that sells a product that is slightly better than its rivals in an international market, can sell millions more units and make a corresponding profit. Meanwhile, having a product that is only slightly inferior can lead to a catastrophic loss of market share. Thus, having the best CEO, or engineers, or marketing staff becomes critical, and therefore firms are willing to pay a premium for the best, which leads to a pseudo winner take all market.
The authors discuss how these sorts of markets, in addition to increasing inequality in society, lead to inefficiencies for society. These inefficiencies come in two forms. First, as the potential rewards for the winner increase, a disproportionate number of people are drawn to work in the "winner take all domain" because of the distortions in incentives for the winner. This leads to fewer productive members of society, and more losers which are a cost/burden to societies (because in a winner take all market, everybody who isn't the winner gets too small a share of the pot to live off of).
Second, the desire to be the best increases because of the incentive structure, which leads to positional arms races. A person who spends money on publicity gets a slight edge over their competitors. So everybody has to spend on publicity, lest they have a competitive disadvantage. But if everybody is spending on publicity (which cancels) they all end up in relative position where they started, minus the budget for publicity. Thus, this commons dilemma leads to a great deal of wasteful spending for no apparent good.
The authors give a host of examples and case studies to support their argument. And in the end, they provide a number of policy recommendations for dealing with winner take all societies:
1) Tax policy - Contrary to traditional economic theory, increasing taxes on the rich in a winner take all market will actually improve productivity and efficiency. The reason is that by reducing the pot that the winner gets, the incentive structures become less distorted. So, fewer people who have no chance of winning enter the market. These people will instead go on to other occupations, and will produce things for society rather than require support from society. This has the nice added benefit of increasing government revenue and thus reducing deficits.
2) Tort reform - The authors argue that large legal settlements are a form of winner take all market, and because of that disproportionately draws some of the most intelligent people in society into a profession that typically does little to create wealth for society, but rather moves existing wealth to different parties. The authors suggest capping and taxing awards to reduce this incentive structure. They also suggest that states should stop subsidizing law schools because it increases the number of players in the game which they argue is deleterious to society.
3) Antitrust Policy - The NFL is able to reduce the winner take all nature of professional football through the institution of a salary cap that constrains the salaries of the best players. In other words, cartels can occasionally have good effects on society by reducing winner take all pressures. Similarly, the authors argue that while there are sometimes important anti-trust regulations, that antitrust policies can often have the incidental effect of creating winner take all markets and causing serious harm to society. The authors urge serious reconsideration about anti-trust regulation and evaluation of specific anti-trust actions using winner take all models of economics.
To quote the authors "The conventional wisdom portrays a world of agonizing trade-offs. We reject this pessimistic conclusion, for, as we have seen, a greater tax burden on the economy's biggest winners would not only help set our financial house in order but would also help steer our most talented citizens to more productive tasks....the redeeming feature of the modern winner-take-all society is that many of the same policies that promote equality also promote economic growth."
I'm not sure I agree with everything the authors argue. In fact, I disagree with a fair amount. However, I found their discussion extremely thought provoking, and a useful perspective on policy debates. I'm not sure how much I would recommend the book itself - it is fairly redundant and while the central premise is interesting a lot of the derivations thereof are best described as sketchy. That said, if you happen to come across the book, reading the first 3 chapters and the last chapter might be worthwhile.
