FILE-In this Thursday, Sept. 13, 2012, file photo, federal Reserve Chairman Ben Bernanke speaks during a news conference in Washington. Federal Reserve wants to find a clearer way to signal to the public when it might start raising interest rates. The Fed has told investors that it plans to keep short-term rates low for at least another three years. But it appears to be leaning toward setting a more specific target, according to minutes from the Fed's last policy meeting. (AP Photo/Manuel Balce Ceneta. File) less
