"Monopsony"?

The new threat of low, low prices:

It is now twenty-five years since the Reagan Administration eviscerated America's century-long tradition of antitrust enforcement. For a generation, big firms have enjoyed almost complete license to use brute economic force to grow only bigger. And so today we find ourselves in a world dominated by immense global oligopolies that every day further limit the flexibility of our economy and our personal freedom within it. There are still many instances of intense competition -- just ask General Motors.

The stakes could not be higher. In systems where oligopolies rule unchecked by the state, competition itself is transformed from a free-for-all into a kind of private-property right, a license to the powerful to fence off entire marketplaces, there to pit supplier against supplier, community against community, and worker against worker, for their own private gain. When oligopolies rule unchecked by the state, what is perverted is the free market itself, and our freedom as individuals within the economy and ultimately within our political system as well.

Popular notions of oligopoly and monopoly tend to focus on the danger that firms, having gained control over a marketplace, will then be able to dictate an unfairly high price, extracting a sort of tax from society as a whole. But what should concern us today even more is a mirror image of monopoly called "monopsony." Monopsony arises when a firm captures the ability to dictate price to its suppliers, because the suppliers have no real choice other than to deal with that buyer. Not all oligopolists rely on the exercise of monopsony, but a large and growing contingent of today's largest firms are built to do just that. The ultimate danger of monopsony is that it deprives the firms that actually manufacture products from obtaining an adequate return on their investment. In other words, the ultimate danger of monopsony is that, over time, it tends to destroy the machines and skills on which we all rely.
