Role of economic forecastingDirk Bezemer in his research [92] credits 12 economists with predicting (with supporting argument and estimates of timing) the crisis: Dean Baker (US), Wynne Godley (US), Fred Harrison (UK), Michael Hudson (US), Eric Janszen (US), Stephen Keen (Australia), Jakob Brøchner Madsen & Jens Kjaer Sørensen (Denmark), Kurt Richebächer (US), Nouriel Roubini(US), Peter Schiff (US), Robert Shiller(US).A cover story in BusinessWeek Magazine claims that economists mostly failed to predict the worst international economic crisis since theGreat Depression of 1930s.[93]. The Wharton School of the University of Pennsylvania online business journal examines why economists failed to predict a major global financial crisis [7]. An article in the New York Times informs that economist Nouriel Roubini warned of such crisis as early as September 2006, and the article goes on to state that the profession of economics is bad at predicting recessions.[94] According toThe Guardian, Roubini was ridiculed for predicting a collapse of the housing market and worldwide recession, while The New York Times labelled him "Dr. Doom".[95] However, there are examples of other experts who gave indications of a financial crisis.[96][97][98][edit]Financial markets impacts[edit]Impacts on financial institutions 2007 bank run on Northern Rock, a UK bankOne of the first victims was Northern Rock, a medium-sized British bank.[99] The highly leveraged nature of its business led the bank to request security from the Bank of England. This in turn led to investor panic and a bank run in mid-September 2007. Calls by Liberal Democrat Shadow Chancellor Vince Cable to nationalise the institution were initially ignored; in February 2008, however, the British government (having failed to find a private sector buyer) relented, and the bank was taken into public hands. Northern Rock's problems proved to be an early indication of the troubles that would soon befall other banks and financial institutions.Initially the companies affected were those directly involved in home construction and mortgage lending such as Northern Rock and Countrywide Financial, as they could no longer obtain financing through the credit markets. Over 100 mortgage lenders went bankrupt during 2007 and 2008. Concerns that investment bank Bear Stearns would collapse in March 2008 resulted in its fire-sale to JP Morgan Chase. The crisis hit its peak in September and October 2008. Several major institutions either failed, were acquired under duress, or were subject to government takeover. These included Lehman Brothers, Merrill Lynch, Fannie Mae, Freddie Mac, and AIG.[100]See also: Federal takeover of Fannie Mae and Freddie Mac[edit]Credit markets and the shadow banking system TED spread and components during 2008During September 2008, the crisis hits its most critical stage. There was the equivalent of a bank run on the money market mutual funds, which frequently invest in commercial paper issued by corporations to fund their operations and payrolls. Withdrawal from money markets were $144.5 billion during one week, versus $7.1 billion the week prior. This interrupted the ability of corporations to rollover (replace) their short-term debt. The U.S. government responded by extending insurance for money market accounts analogous to bank deposit insurance via a temporary guarantee[101] and with Federal Reserve programs to purchase commercial paper. The TED spread, an indicator of perceived credit risk in the general economy, spiked up in July 2007, remained volatile for a year, then spiked even higher in September 2008,[102] reaching a record 4.65% on October 10, 2008.In a dramatic meeting on September 18, 2008 Treasury Secretary Henry Paulson and Fed Chairman Ben Bernanke met with key legislators to propose a $700 billion emergency bailout. Bernanke reportedly tells them: "If we don't do this, we may not have an economy on Monday."[103] The Emergency Economic Stabilization Act also called the Troubled Asset Relief Program (TARP) is signed into law on October 3, 2008.[104]Economist Paul Krugman and U.S. Treasury Secretary Timothy Geithner explain the credit crisis via the implosion of the shadow banking system, which had grown to nearly equal the importance of the traditional commercial banking sector as described above. Without the ability to obtain investor funds in exchange for most types of mortgage-backed securities or asset-backed commercial paper, investment banks and other entities in the shadow banking system could not provide funds to mortgage firms and other corporations.[12][58]This meant that nearly one-third of the U.S. lending mechanism was frozen and continued to be frozen into June 2009.[105] According to theBrookings Institution, the traditional banking system does not have the capital to close this gap as of June 2009: "It would take a number of years of strong profits to generate sufficient capital to support that additional lending volume." The authors also indicate that some forms of securitization are "likely to vanish forever, having been an artifact of excessively loose credit conditions." While traditional banks have raised their lending standards, it was the collapse of the shadow banking system that is the primary cause of the reduction in funds available for borrowing.[106][edit]Wealth effectsThere is a direct relationship between declines in wealth, and declines in consumption and business investment, which along with government spending represent the economic engine. Between June 2007 and November 2008, Americans lost an estimated average of more than a quarter of their collective net worth. By early November 2008, a broad U.S. stock index the S&P 500, was down 45 percent from its 2007 high. Housing prices had dropped 20% from their 2006 peak, with futures markets signaling a 30-35% potential drop. Total home equity in the United States, which was valued at $13 trillion at its peak in 2006, had dropped to $8.8 trillion by mid-2008 and was still falling in late 2008. Total retirement assets, Americans' second-largest household asset, dropped by 22 percent, from $10.3 trillion in 2006 to $8 trillion in mid-2008. During the same period, savings and investment assets (apart from retirement savings) lost $1.2 trillion and pension assets lost $1.3 trillion. Taken together, these losses total a staggering $8.3 trillion.[107] Since peaking in the second quarter of 2007, household wealth is down $14 trillion.[108]Further, U.S. homeowners had extracted significant equity in their homes in the years leading up to the crisis, which they could no longer do once housing prices collapsed. Free cash used by consumers from home equity extraction doubled from $627 billion in 2001 to $1,428 billion in 2005 as the housing bubble built, a total of nearly $5 trillion over the period.[16][17][18] U.S. home mortgage debt relative to GDP increased from an average of 46% during the 1990s to 73% during 2008, reaching $10.5 trillion.[19]To offset this decline in consumption and lending capacity, the U.S. government and U.S. Federal Reserve have committed $13.9 trillion, of which $6.8 trillion has been invested or spent, as of June 2009.[109] In effect, the Fed has gone from being the "lender of last resort" to the "lender of only resort" for a significant portion of the economy. In some cases the Fed can now be considered the "buyer of last resort."
