Economists predicting moderate growth in 2013 Associated Press Copyright 2013 Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed. Published 3:06 am, Monday, February 25, 2013 WASHINGTON (AP) — Business economists expect 2013 will be another year of sub-par growth for the U.S. economy, reflecting uncertainty stemming from the budget battles in Washington and Europe's on-going debt problems. The GDP, the economy's total output of goods and services, shrank in 2008 and 2009 as the country went through the worst economic contraction since the Great Depression of the 1930s. [...] economic growth has been modest as the economy has been held back by a variety of factors including prolonged unemployment. "While the NABE forecasters see fiscal threats, they are optimistic that there will be some resolution toward the second half of this year and that will result in an improvement in many of the numbers is 2014," said Nayantara Hensel, an economics professor at the National Defense University in Washington and a member of the NABE forecasting panel. "The problems in Europe and our own domestic fiscal drama will keep the investment outlook subdued," said Kenneth Simonson, chief economist for the Associated General Contractors of America and a member of the NABE panel.
