Dead Ideas from Live Economists: The Efficient Markets Hypothesis
When the capital development of a country becomes a by-product of the activities of a casino, the job is likely to be ill-done, JM Keynes, General Theory of Employment, Interest and Money Ch 12, p142 in Google Book edition, Atlantic Publishers
If there is one economic doctrine that has been central to thinking about economic and social policy over the last three decades, it is the Efficient Markets Hypothesis, or more properly, the efficient financial markets hypothesis. The EMH says that financial markets are the best possible guide to the value of economic assets and therefore to decisions about investment and production.
Although economists since Adam Smith have pointed out the virtues of markets in general, the EMH with its focus on financial markets is specific to the era of finance-driven capitalism that emerged from the breakdown of the Keynesian Bretton Woods system in the 1970s. The EMH justified, and indeed demanded, financial deregulation, the removal of controls on international capital flows and the massive expansion of the financial sector that ultimately produced the greatest financial crisis in history.

Keynes and the casino
Few economists have been successful investors, and quite a few have been disastrous failures. But after a narrow escape from disaster early in his investing career John Maynard Keynes made a fortune for his Cambridge college by speculating in futures markets It is a striking paradox that Keynes was among the most scathing of all economists in his assessment of the role of financial markets.
“Speculators may do no harm as bubbles on a steady stream of enterprise. But the position is serious when enterprise becomes the bubble on a whirlpool of speculation. When the capital development of a country becomes a by-product of the activities of a casino, the job is likely to be ill-done” (General Theory Ch 12, p142 in Google Book edition, Atlantic Publishers
During the decades of the long Keynesian boom, financial markets were tightly regulated, and, as a result, financial crises disappeared almost entirely from the experience and memory of the developed world. At the margin, substantial profits could be made by finding ways to work around the regulations, while relying on governments to maintain the stability of the system as a whole. Not surprisingly, there was a warm reception for theoretical arguments that presented a more favorable view of financial markets.
Keynes’ views were reflected in the systems of financial regulation adopted as governments sought to rebuild national economies and the global economic system in the wake of World War II. The international negotiations undertaken at a meeting in Bretton Woods, New Hampshire, in 1944, where Keynes represented the British government, established an international framework in which exchange rates were fixed and movements of capital tightly controlled.
National governments similarly adopted policies of stringent financial regulation, and established a range of publicly-owned financial institutions in response to the failures of the private market. In the United States, a host of regulatory bodies were established to control financial institutions. The Glass-Steagall Act established the Federal Deposit Insurance Corporation (FDIC) and prohibited bank holding company from owning other financial companies. The Federal National Mortgage Association (later quasi-privatised as Fannie Mae, and then renationalised during the early stages of the 2008 meltdown) was established to support the mortgage market.
Although the details of intervention varied from country to country, the effect was the same everywhere. Banking in the 1950s and 1960s was a dull but secure business, resembling a public utility in many respects. Parents scarred by the Depression urged their children to look for ‘a nice safe job in a bank’.
The Efficient Markets Hypothesis changed all that.
