The International Monetary Fund’s (IMF) World Economic Outlook, released on Monday, says tax cuts in the United States will improve U.S. investment and help its trading partners. In Davos, the Washington-based IMF revised its global forecast upward, to 3.9% for both 2018 and 2019, a 0.2% improvement from its October prediction. It cited the new U.S. tax package, which while increasing the deficit, cuts corporate tax rates from 39 to 21% and reduces some individuals’ tax payments.
