The International Monetary Fund is slightly more optimistic about the global and U.S. economies this year than it was three months ago.

In an updated outlook released Tuesday, the global lending organization forecasts that the world economy will grow 3.7 percent in 2014 and that the U.S. economy will grow 2.8 percent. The global forecast is 0.1 percentage point higher and the U.S. forecast 0.2 point higher than the IMF’s October forecast.
