Why is real wage growth anemic? It’s not because of a skills shortage

Despite an unemployment rate at 4.1 percent or less since last October, wage growth has been anemic. In fact, over the last year, the average real wage of private sector workers saw no growth at all. While the total lack of growth in inflation-adjusted (real) wages over the last year is due in part to an increase in energy prices that is likely temporary, the slow real wage growth we’ve seen in recent years is mostly driven by nominal wages failing to rise quickly even in the face of low unemployment.

Some have posited that our far-less-than-stellar wage growth right now could be due to workers not having the skills employers need. But that idea has the logic backwards. When employers can’t find workers with the skills they need at the wages they are offering, they will raise wages in order to attract qualified workers—if employers can’t find the workers they need among the unemployed, they will offer higher wages in an attempt to poach needed workers from other firms, who will then raise wages in an attempt to keep their workers, and so on. In other words, if there are skills shortages, we should see signs of faster wage growth for workers with needed skills. This fast wage growth for skilled workers should push up average wages, not weigh them down. Since we continue to see anemic average wage growth, not just slow wage growth for select groups of workers, it’s clear that there is not a widespread shortage of the types of workers (i.e., those with the right skills) that employers need.

But we certainly hear widespread employer complaints about not being able to find workers. Why? One reason is monopsony power in the U.S. labor market. There is a lot of evidence that many firms have monopsony power, either because of a limited number of buyers of labor or other sources beyond labor market concentration. When firms have monopsony power, they are able to pay workers less than what their work is “worth,” i.e. less than their marginal product.

So when a firm with the power to set wages below a workers’ marginal product complains about not being able to find workers at the wages they are offering, it’s useful to remember that they are choosing to keep wages low in order to increase profits—which remain high as a share of corporate sector income—and could get more workers by simply raising wages. And importantly, when firms with monopsony power complain about not being able to find workers, it is not adequate evidence of a skills shortage.

Remember, while labor shortages may be a negative for firms, they are a clear win for workers, since they lead to wage increases. Right now there is scant legitimate evidence of anything but isolated concerns about scarce labor, but in today’s environment of unusually weak wage growth, somewhat more widespread labor shortages that put upward pressure on wages would in fact be a welcome development.
