(CBS) In a rare and frank interview, Federal Reserve Chairman Ben Bernanke talks to “60 Minutes” correspondent Scott Pelley about the troubled economy and the measures the central bank has taken to improve it for a segment to be broadcast this Sunday, Dec. 5, at 7 p.m. ET/PT.

Bernanke’s interview took place in Columbus, Ohio, last Tuesday (Nov. 30) and addresses several pressing economic matters, including deepening unemployment, the prospects of a second recession and taxes. He also talks about the federal deficit and reforming the tax code.

He explains why the Fed announced its intention to buy $600 billion in Treasury securities, defending against charges the move will lead to inflation and not ruling out the purchase of more.

The Fed chair also addressed the federal deficit.
