Former Fed Chair Alan Greenspan dies at 100

Alan Greenspan, the former Federal Reserve chair whose long tenure made him one of the most influential US economic policymakers of his generation, died Monday at 100. His wife, Andrea Mitchell, said he died at home from complications of Parkinson's disease. Greenspan led the central bank from 1987, after his appointment by President Ronald Reagan, until 2006, giving him the second-longest term in the job after William McChesney Martin. He became closely associated with the 1996 warning about "irrational exuberance," a phrase that jolted global markets and came to define debate over asset bubbles. Admirers credited him with steering the economy through long growth periods, while critics later tied his easy-money approach to risks that fed the 2008 financial crisis.
