2017 was a good year for jobs. Over the past year, (November 2016 to November 2017, the latest figure available), unemployment’s fallen by half a percent to just 4.1 percent. And according to orthodox economics, that means we’re hovering around full employment.

Which in turn would lead to a rapid rise in inflation. But so far, even with low unemployment, wage increases have been moderate. Average hourly earnings increased 2.5 percent in the past year. That’s not much faster than consumer prices. So inflation?
