The creeping influence of oligopolies

The creeping influence of oligopolies
Several factors are propelling the might of a few companies in any one industry

A basic lesson of economics is that monopolies are bad news. When there’s only one company in a market, it can jack up prices to above their efficient level.
That gives a big boost to profits, but results in too few people being able to afford to buy what the company is selling. Most markets are not monopolies, but a similar principle holds for situations where there are only a few companies, called oligopolies. A lack of players stifles competition, raising profits but lowering overall economic output.
It’s therefore natural to ask whether the US’s subpar economic growth is caused by a decrease in competition, and in fact, a bunch of people have been suggesting this explanation lately. In an article entitled “Too much of a good thing?”, the Economist cites high rates of profit, record levels of merger activity and increasing industrial concentration as evidence of reduced competition.
I’m not sure it’s a bulletproof case. It’s true that after-tax profits are historically high as a per cent of gross domestic product. But pretax profits might be a better measure of market power, since they represent companies’ ability to wring value out of the economy (some of which then goes to the government as taxes).
Information from the Federal Reserve Board of St. Louis shows that pretax profits are high relative to the 1980s and ‘90s, but are only back up to the level that prevailed from the ‘50s through the ‘70s. Nor is merger and acquisition activity unusually high. Although last year was a record, the number and total value of merger deals has been pretty stable since the turn of the century.

How about those big banks? The US’s megabanks may still be too big to fail, but the sector still is much than in countries such as Canada, Germany, Japan and the UK.
The airline sector is the poster child for high concentration in US industry. But this might have merely been what the industry needed to survive. Profit margins have traditionally been so razor-thin that US airline bankruptcies for decades were regular headlines in the news. The recent consolidation might serve only to raise airline profits to normal, sustainable levels.
Has federal antitrust enforcement become more lax? Not according to the law firm Gibson & Dunn, which reports that fines for anticompetititive behaviour have been increasing for a decade.
So the evidence that the US has become less hostile to oligopolies is mixed. Larry Summers, however, raises an interesting point when he contrasts the recent rise in profit with the decline in corporate investment: “If monopoly power increased one would expect to see higher profits, lower investment as firms restricted output, and lower interest rates as the demand for capital was reduced. This is exactly what we have seen in recent years! Only the monopoly power story can convincingly account for the divergence between the profit rate and the behaviour of real interest rates and investment.”
Summers also brings up the possibility that information technology is making it much easier for companies to be monopolies, by creating strong network effects or by extending their reach across larger geographical areas. I too have suggested this idea recently. Another force pushing us toward increased industrial concentration might be globalisation — proponent theories predict that international trade leads to a larger number of companies around the world, but fewer within each country.
There is also some academic work suggesting that financial innovation may be reducing competition much more than would be implied by the modest rise in industrial concentration. The University of Michigan’s Martin Schmalz, along with private-sector co-authors Isabel Tecu and Jose Azar, recently found that when mutual funds own pieces of a number of different companies in an industry, competition in that sector falls.
Passive investing — index funds, exchange-traded funds and the like — has led to an increase in this sort of distributed ownership. Those new funds have allowed investors to diversify their risk, but that may be coming at the expense of healthy industry competition.
So we should definitely be keeping a wary eye on the level of competition in the economy.
More importantly, the problem of competition requires a broad shift in our thinking about the proper roles of government and private industry. Free market orthodoxy has taught generations of Americans to think that the private sector runs best when left to its own devices, but monopoly power throws a big wrench into the equation.
If the level of competition fluctuates naturally as technology, finance and globalisation change, then the appropriate level of government intervention changes too. It may be that an efficient economy needs government to constantly fine-tune a nation’s industrial structure, enforcing antitrust more stringently when natural forces diminish competition, but backing off when competition increases on its own.
