The Manufacturers Alliance for Productivity and Innovation (MAPI) Foundation has released its fourth quarter forecast for 2017. MAPI currently projects that U.S. GDP growth will average 2.1% between 2017 and 2021, slightly slower than the 2.2% average for the 2017-2020 period projected in a September report. The acceleration in global economic growth that began in late 2016 looks increasingly sustainable. A marked improvement in economic activity is becoming apparent in regions that matter to U.S. manufacturing prospects, including East Asia, the Eurozone, and Canada. This report offers a range of scenarios for U.S. manufacturing growth through 2021 of between 1.2 % and 1.8 %.
