THE CORNER | As expected, U.S. President Barack Obama appointed Janet Yellen as the Federal Reserve’s next leader, the first woman in the 100-year-history of the central bank. Among her first words: “More needs to be done to strengthen the recovery,” even though progress has been made, and: “too many Americans still cannot find a job and worry how they will pay their bills and provide for their families.” Were those hints about how she will deal with QE? Although she is considered a dove, some analysts believe that is a bit overstated. Anyway Obama called her “tough”, joking that it was not just because she was born in Brooklyn.
