Nobel Prize-winning economist Paul Krugman and Niall Ferguson, author of “The Ascent of Money: A Financial History of the World,” clashed anew today over how to revive the U.S. economy.
Krugman, 57, a Princeton University professor, is urging the Obama administration to undertake a second round of fiscal stimulus, while Harvard University historian Ferguson, 46, warns such a course may trigger a “debt spiral” in the world’s biggest economy.
