A popular line on our recent surge of inflation is that an over-tight labor market has led to rapid wage growth, which in turn forces companies to raise prices. Higher prices in turn lead workers to demand higher wages, which will give us a wage-price spiral and soon lead to double-digit inflation.

While this was a story that plausibly fit the data in the 1970s, it is very hard to make the wage-price spiral fit the current situation for a simple reason: The wage share of income has fallen sharply since the pandemic. By wage share I mean total compensation to workers, including fringe benefits, not just cash wages and salaries.

Here’s the picture:

As can be seen, the wage share of corporate income had been recovering gradually from the troughs it hit in 2014 following the Great Recession. However, we see a sharp reversal in 2021, with the wage share falling from 76.1 percent to 73.7 percent, a decline of 2.4 percentage points.

Perhaps some economists can tell a story where rapid wage growth is driving inflation even as the wage share of income is falling, but I’m not that good an economist. [Editor’s Note: “Good” as in dishonest.]

This still looks to me like a case where supply-side disruptions, associated with the economy reopening from the pandemic together with the war in Ukraine are driving inflation.

This view is consistent with the fact that year-over-year inflation in the European Union was 7.5 percent as of March. The EU countries did not have as big a stimulus as the United States and by most measures the EU labor market is not as tight as in the United States.
