Robert Skidelsky, a member of the British House of Lords and Professor Emeritus of Political Economy at Warwick University, was a non-executive director of the private Russian oil company PJSC Russneft from 2016 to 2021. The author of a three-volume biography of John Maynard Keynes, he began his political career in the Labour party, became the Conservative Party’s spokesman for Treasury affairs in the House of Lords, and was eventually forced out of the Conservative Party for his opposition to NATO’s intervention in Kosovo in 1999.
LONDON – Mainstream economics subscribes to the theory that markets “clear” continuously. The theory’s big idea is that if wages and prices are completely flexible, resources will be fully employed, so that any shock to the system will result in instantaneous adjustment of wages and prices to the new situation.
This system-wide responsiveness depends on economic agents having perfect information about the future, which is manifestly absurd. Nevertheless, mainstream economists believe that economic actors possess enough information to lend their theorizing a sufficient dose of reality.
The aspect of the theory that applies particularly to financial markets is called the “efficient market theory,” which should have blown sky-high by last autumn’s financial breakdown. But I doubt that it has. Seventy years ago, John Maynard Keynes pointed out its fallacy. When shocks to the system occur, agents do not know what will happen next.
