Weekly Inflation Outlook: Have We Seen the Peak?

On Friday, investors freaked out a bit when the employment report showed not just a slightly-higher-than-expected growth in new jobs but also a significant miss to the high side on average hourly earnings (AHE) along with a big upward revision to prior months.

First point to make: if you’re looking at an economic series that has large and frequent revisions, you shouldn’t make big decisions on the basis of it.

For example, let’s suppose you are the head of the world’s largest and most powerful central bank, and you believe (for some reason contrary to what the data suggest) that inflation is partly caused by high wages, so that you need wages to fall in order to have inflation fall. If you were such a person, and believed such a thing, then what you most certainly should not do is rely on average hourly earnings to tell you what wages are doing.

Unfortunately, Chairman Powell last week said exactly those things. The Fed wants to see wages decline to something “consistent with 2% inflation,” and he specifically mentioned AHE. More nonsense from central bankers. Never mind that all sorts of wages are consistent with 2% inflation—the whole “Phillips Curve is broken” meme was based on the re-interpretation (post-Phillips) of the curve as relating unemployment to inflation rather than to wages, and since wages and inflation are not tightly bound it means the Phillips Curve defined a way that Phillips didn’t define it doesn’t work. So that’s strike one. But if you were an economist in charge of monetary policy and you insisted on believing that a certain level of wage growth is “consistent with 2% inflation,” you certainly would not measure that wage growth with AHE!

That’s partly because AHE is volatile and frequently-revised, and partly because it is highly sensitive to the composition of the workforce. When new entrants to the labor market are largely in low-skilled industries, it biases the average lower, and vice-versa. Heck, average anything—including CPI and PCE, compared to their median counterparts—is fraught. But AHE is particularly bad.

Here is a chart showing AHE and the Atlanta Fed’s Wage Growth Tracker. The WGT tracks the median wage of people in the sample who were employed at both the beginning and end of the sample period. Ergo, there is no change in the sample composition. It is both more stable, and (as I’ve shown previously) has been much more stable with respect to median inflation. There is no noticeable and stable relationship between AHE and CPI.
