Economic forecasters divide into two groups: those who cannot know the future but think they can, and those who recognize their inability to know the future. Shifts in the economy are rarely forecast and often not fully recognized until they have been under way for some time. So judgments about the U.S. economy have to be tentative. What can be said is that for the first time in five years a resumption of growth significantly above the economy’s potential now appears as a substantial possibility. Put differently, after years when the risks to the consensus modest-growth forecast were to the downside, they are now very much two-sided.
