If you
believe in what's called the "efficient
markets Hypothesis" then the 2007 financial crises shouldn't have
occurred because free markets have the ability to self-correct.
The 2007 financial crises revealed that much of the recent productivity growth in finance was achieved through the debasement of its products - the creation of overly complex, riskier, and even fraudulent products. The complexity of the new financial product, 'Asset Backed Securities' (ABS's); 'Collateral Debt Obligations' (CDO's) and 'Credit Default Swaps' (CDS), is exactly what made them dangerous and what nearly brought the capitalist financial system crashing down.
Markets may transmit information, but what reason is there to believe that - unlike any other institution - they have a built-in capacity to correct their mistakes? Moods of irrational exuberance and panic can, and often do, swamp the price discovery functions of markets.
To avoid a worldwide economic slump and depression which occurred after the 1929 'Wall Street Crash', governments adopted Keynesian policies. They bailed out some firms, bought toxic debts, and injected money into the financial system to shore it up. It was a kind of socialism for the rich and the free market for the rest of us.
The American economist, Eugene Fama, of the Chicago School, took a different view. He argued that financial markets were a casualty of the recession and did not cause it. For Farma, the U.S. government made lending too easy, credit too easy and too easy to obtain. He maintained that banks acted rationally in responding to incentives put in place by an interfering government and that unencumbered markets work efficiently. Fama won the Nobel Prize for economics, but there were many other financial crises before 2007, and they seemed to have been triggered by excessive liberalisation in the financial markets.
In 1982, Chile got into a major banking crisis following radical financial market liberalization and there were banking crises in Sweden, Finland and Norway, following financial deregulation. There was the 'tequila' crisis in Mexico in 1994-1995, and a crisis in the economies of Asia, Thailand, Indonesia, Malaysia and South Korea, in 1987, which resulted from financial deregulation.
Some do argue that this theory called the efficient market hypothesis, played a key role in the making of the 2007 financial crisis because it made policy-makers believe that financial markets needed no regulation.
