Federal Reserve Bank of Boston President Eric Rosengren talks about the jobless rate and changing inflation dynamics. David Lipton, the first deputy managing director of the IMF, says the IMF has favored tax reform in the U.S. for a long time. David Malpass, the under secretary of the Treasury for International Affairs, says he'd like to see more growth in the U.S. and abroad. Nouriel Roubini, a professor at NYU's Stern School of Business, says monetary policy should be more aggressive if inflation is going to stay low. Finally, Pierre Moscovici, the European Commissioner for Economic and Financial Affairs, Taxation and Customs, says populism in Europe has lost battles but not the war.
