Negotiations over the U.S. debt ceiling are still one of the biggest risks facing the world, according to Davos delegates including Marissa Mayer, chief executive of Yahoo and Judith Rodin, president of the Rockefeller Foundation.
Mayer told a CNBC debate on the global agenda for 2014 at the World Economic Forum in Davos that she believes "the U.S. government is as partisan as it has ever been" in her lifetime.

The next deadline for the U.S. to be unable to borrow any more money to add to its $17 trillion debt pile is February 7. The last time it hit its debt ceiling, in May, a bad-tempered spat between Republicans and Democrats in Congress went right to the wire of when the U.S. might miss its debt payments, in October, and sent markets yo-yoing.
"I don't see a true bipartisan resolution," Rodin said. "There will be less acrimony."
U.S. politicians scared themselves with how close they came to the brink last time, and will be less heated this time around, she argued.
