Yellen becomes world's most powerful woman
ECONOMIST Janet Yellen has been nominated by US president Barack Obama to take over as chairperson of the US Federal Reserve, the most influential central bank on earth.
As chair of the Fed, an institution that can influence the course of the world economy, she arguably replaces German chancellor Angela Merkel as the most powerful woman in the world.
Ms Yellen (left) is widely viewed as a safe pair of hands. She is expected to continue with massive money-printing policies established by her predecessor Ben Bernanke to shore up the US economy.
