Goldman Sachs Chief Economist Jan Hatzius says inflation would come down quicker if President-elect Donald Trump does not institute tariffs on all imports. Trump has promised 10% to 20% across-the-board tariffs on all imported goods. Hatzius also says he expects the Federal Reserve to cut interest rates three times this year. He is joined by Bloomberg's Matt Miller, Katie Greifeld, and Sonali Basak.
