What is ahead for the American economy?  Martin Feldstein, president emeritus of the National Bureau of Economic Research and George F. Baker Professor of Economics at Harvard University, visited the University of Maryland’s Robert H. Smith School of Business last week to address this question.  In his comments to faculty and students, Feldstein stressed that today’s slow growth rate would continue into 2014 but that the long-term prospects for the U.S. are bright, so long as the large and growing national debt is curtailed.
