The culprit is fingered

Stanford University economist John B. Taylor has done some investigating, and he thinks he'd fingered a culprit in the financial crisis. From the Wall Street Journal:

Many are calling for a 9/11-type commission to investigate the financial crisis. Any such investigation should not rule out government itself as a major culprit. My research shows that government actions and interventions -- not any inherent failure or instability of the private economy -- caused, prolonged and dramatically worsened the crisis. ...

Monetary excesses were the main cause of the boom. The Fed held its target interest rate, especially in 2003-2005, well below known monetary guidelines that say what good policy should be based on historical experience. Keeping interest rates on the track that worked well in the past two decades, rather than keeping rates so low, would have prevented the boom and the bust. Researchers at the Organization for Economic Cooperation and Development have provided corroborating evidence from other countries: The greater the degree of monetary excess in a country, the larger was the housing boom.

The effects of the boom and bust were amplified by several complicating factors including the use of subprime and adjustable-rate mortgages, which led to excessive risk taking. There is also evidence the excessive risk taking was encouraged by the excessively low interest rates. Delinquency rates and foreclosure rates are inversely related to housing price inflation. These rates declined rapidly during the years housing prices rose rapidly, likely throwing mortgage underwriting programs off track and misleading many people.

Adjustable-rate, subprime and other mortgages were packed into mortgage-backed securities of great complexity. Rating agencies underestimated the risk of these securities, either because of a lack of competition, poor accountability, or most likely the inherent difficulty in assessing risk due to the complexity.

Other government actions were at play: The government-sponsored enterprises Fannie Mae and Freddie Mac were encouraged to expand and buy mortgage-backed securities, including those formed with the risky subprime mortgages.

Government action also helped prolong the crisis. Consider that the financial crisis became acute on Aug. 9 and 10, 2007, when money-market interest rates rose dramatically. Interest rate spreads, such as the difference between three-month and overnight interbank loans, jumped to unprecedented levels.

But, of course, the people who got us into this mess are well-equipped to get us out.
