Discuss the major intellectual failure on macroeconomics from the crisis.

What will be an ideal response?

ANSWER:

The failure was in not realizing that such a large crisis could happen,that the characteristics of the economy were such that a relatively small shock, in this case the decrease in U.S. housing prices, could lead to a major financial and macroeconomic global crisis. The source of the failure, in turn, was a lack of focus on the role of the financial institutions in the economy.
