摘要：It is a great pleasure and honor for me to participate in a panel
with Ben Friedman on very topical themes for a central banker.
The financial crisis that began in August 2007 changed the role of
monetary policy. In particular, it blurred the borderline dividing
monetary policy from fiscal policy, and gave rise to new questions.
In my remarks for this closing panel of the Conference in Honor of
Ben Friedman, I would like to address some aspects of this issue.
