Alan Greenspan

Alan Greenspan is an American economist who served as Chairman of the Federal Reserve from 1987 to 2006, the second-longest tenure in that position.

Initially appointed by President Reagan, he was reappointed by subsequent presidents until his retirement.

Greenspan's tenure was marked by his support for deregulation and low interest rates.

While once highly regarded, his reputation has been tarnished by critics who argue his policies contributed to the dot-com bubble and the 2008 financial crisis.

Greenspan defends his actions, attributing the housing bubble to global factors rather than Fed policies.

After leaving the Fed, he founded a consulting firm and continues to comment on economic issues.
