The world's largest economy expanded at a faster pace than a quarter ago, however, still at anaemic rate at the end of last year. The Commerce Department said Friday, that the U.S. economy grew by 0.4% in the October-December quarter, up from 0.1% growth recorded in the previous quarter, but below analysts' forecasts, who claimed for a 0.5% growth. The revision reflected stronger business investment and export sales. Despite the sluggish growth rate, there is hope that growth will accelerate in early 2013, even despite higher taxes and cuts in government spending.
