Economists believe we have only one more year of Ben Bernanke's tumultuous tenure as chairman of the Federal Reserve. And most think that's bad news for the economy.

More than two-thirds of economists surveyed by CNNMoney said Bernanke likely won't be back for a third term. His current term ends on Jan. 31, 2014. Many believe the choice to stay or go will be his.

"He is likely to opt to leave after his term expires in 2014," said Lynn Reaser, chief economist for Point Loma Nazarene University. "He would be reappointed if he chose to stay." Several economists said they believe Bernanke would prefer to return to teaching at Princeton University.
