The Paris-based Organization for Economic Cooperation and Development (OECD) has revised its global economic forecast, and things are looking up. It’s predicting 3.3 percent global growth in 2017, up from 2.9 this year and 0.1 percent higher than the prediction it issued in September. The organization is anticipating some stimulus to the U.S. economy under President-elect Donald Trump, who has promised $1 trillion in infrastructure investments, although the details of that idea are sketchy and subject to a political battle.
