Re: Our Next President?
My thinking about this stuff was much more like this a decade ago. I've since revised it. Why?
1. It assumes labor's share as a constant. Most econ did. Turns out, it's shrinking.
2. This has serious implications for the relationship between unemployment rates and labor markets. If you've ever scratched your head at how unemployment can be near historic lows without wage increases, you're assuming labor's share is constant. If it's shrinking, it makes perfect sense that unemployment could drop to 0%--there could even be a labor shortage--and still real wages can stay flat or even decrease.
3. This is a fundamentally different environment than in the 1970s when labor's share was a constant and wages pushed stagflation.
I haven't quite bought into the whole MMT model. But I don't have to in order to be more skeptical of inflationary concerns. That does not mean that interest payments on the debt cannot grow so large they chew up an uncomfortably large chunk of the annual discretionary budget. But I think it does mean there's much stronger headwinds against inflation than there were before labor's share began shrinking. And I think it explains why the simple supply and demand explanation of wages never seems to pan out with much real wage growth anymore.
It's not a super complicated thing to understand. For the last 20 years the real pie's growing, albeit slowly at about 2% per annum. But over that same time, labor's total share of that pie shrunk by about 14%. Most people earn most of their money from labor income. Seems to me that's how these seemingly counterintuitive macro things can happen. It's also why I'm less hawkish about inflation--within limits roughly bounded by labor's loss. So at this point, to put a figure on it, I'd say roughly $2T per year in the US on the fiscal side before you really overcome the headwinds and face real inflationary danger. We're at about half of that.
Think what you want about the Fed, but their model projections have been pretty good. The two spots where they have been persistently and predictably off in the same direction have been that inflation and wages have remained lower than expectations. To me, this is a reasonable answer as to why.
The folk wisdom and textbook econ people have learned does not treat labor's share as a long-term shifting variable. But it is.
