The U.S. unemployment rate declined to 7.7% in February 2013 from 7.9% in January, with 236,000 jobs added. IHS Global Insight's forecast of GDP growth is 1.5% for the first half of 2013 because of spending cuts and the increase in Social Security taxes in Jan 2013. Macroeconomic Advisors predicts the federal spending cuts will lead to loss of about 700,000 jobs, with most of this ocurring in the second and third quarters. As a result economists expect the unemployment rate to be at about 7.5% by the end of 2013. The job gains were broad based including manufacturing and business services, and 48,000 construction jobs were addd. At the same time the labor force participation rate declined to 63.5% reflecting some workers retiring and some discouraged workers dropping out of the job market.
