The chart above shows the Y/Y percentage change in the average hourly earnings of nonsupervisory employees. We can break this data down into two sections. Due to higher inflation and stronger unions, the pace of growth was far stronger before the 1980s.
We see a different dynamic at work during the first three post-1982 expansions. Wages decline coming out of the recesssion, falling to ~2% Y/Y percentage growth rate. They then climb during the second half of the expansion, peaking ~4% Y/Y percentage growth rate. This probably explains why the Fed remains thoroughly convinced that the Phillip’s Curve is still in play: they’re assuing the past is prologue, and with good reason.
However, this expansion we see a different growth dynamic at work. As before, the Y/Y percentage change dropped to 2% a little before the expansion was halfway over. But the pace of growth in the second half of the recovery is far weaker. Hence, we have weaker wage growth.
Here’s a graph of the average and median growth rate of wages for each of the expansions:
The pace is clearly declining.
The first section coincides with the increase in the workforce due to women entering. This fits with the idea that we get growth when firms plan for growth, which they did when they could see that consuming households would have more money to spend.
In that light the dot-com boom was a blip.
This appears to be a demonstration that wage growth is not related to profit growth…as republicans would like us to believe.
