Great Recession

The Great Recession was a period of contraction in economies around the world (particularly in the western world and associated countries) that occurred from late 2007 to mid-2009, overlapping with the closely related 2008 financial crisis. The scale and timing of the recession varied from country to country (see map). At the time, the International Monetary Fund (IMF) concluded that it was the most severe economic and financial meltdown since the Great Depression of the 1930s.

When housing prices fell and homeowners began to abandon their mortgages, the value of mortgage-backed securities held by investment banks declined sharply in 2007–2008, causing several banks to collapse or be bailed out in September 2008.

As with most other recessions, it appears that no known formal theoretical or empirical model succeeded in accurately predicting the onset of this recession, except for minor signals in the sudden rise of forecast probabilities, which were still well under 50%. The recession was not felt equally around the world. Whereas most of the world's developed economies, particularly in North America and Europe, fell into a severe, sustained...
