As George Akerlof and I argue in our recent book Animal Spirits , the current financial crisis was driven by speculative bubbles in the housing market, the stock market, and energy and other commodities markets. Bubbles are caused by feedback loops: rising speculative prices encourage optimism, which encourages more buying, and hence further speculative price increases – until the crash comes.
[…] Yet events like the Great Depression, as well as the recent crisis, will never be fully understood without understanding bubbles. The fact that monetary-policy mistakes were an important cause of the Great Depression does not mean that we completely understand that crisis, or that other crises (including the current one) fit that mold.
