Pushing back gently but firmly on Michael Strain’s non-stagnation argument
A few folks have asked me about my friend Michael Strain’s recent Bloomberg piece where he argues against wage stagnation (it’s “more wrong than right”). It’s an old argument but one worth having, and Michael makes some important points and misses some big ones too (5, to be precise).
Larry Mishel and I counter a much shorter-term version of Michael’s case here but similar issues pertain. Certainly, the evidence he presents doesn’t change the basic wage story that I and many others carry around in our heads.
I think Michael’s most germane point is that nobody defines “stagnation.” If you think stagnation means real wages for low-wage workers have never gone up in the past four decades, you’re wrong. The figure below, from a recent piece I published (one I’ll get back to re a key point Michael misses), shows real wages for low and moderate wage workers stagnated through the 1970s, 80s, and 2000s.
But, in periods of very tight labor markets—the latter 1990s and now—they grew at a decent clip. This is key insight #1about real wage growth for too many workers. It’s not that they’ve never grown. It’s that their growth periods in recent decades have been few and far between. And it’s largely dependent of achieving persistent full employment, a condition that’s also been too rare in recent years (see this exciting new paper on precisely this point!).
Key insight #2 is that, sure, switching to a slower-growing deflator leads to faster wage growth and there are good arguments for various choices (see Mishel/Bivens’ cautions re Michael’s choice of using the PCE for wages). But it doesn’t wipe out long periods of stagnation. Here’s the real 20th percentile wage (2018 $’s) using both the CPI-RS (used in the figure above) and the PCE. Just like the above figure: periods of growth, but longer periods of stagnation.
