The US Federal Reserve on Wednesday widened its growth outlook for 2014 and lowered its forecast for unemployment next year. The Fed projected gross domestic product growth between 2.8 percent and 3.2 percent, a tenth point wider than the 2.9-3.1 percent range it projected in September. It projected the unemployment rate, currently at 7.0 percent, would fall to a range of 6.3-6.6 percent next year, an improvement from the prior estimate of 6.4-6.8 percent.
