"Global crises are very rare events. After the Great Depression and the Great Stagflation, new macroeconomic paradigms associated with a new policy regime emerged.

It questions how the field of economics -- still reeling from the global financial crisis initiated in the summer of 2007 -- will respond" -Back cover.
