Subsiding Inflation
Calculated Risk informs us that key measures of inflation have subsided. Still no hyperinflation by 2010.
To be fair, while the inflationistas have been totally wrong, deflationistas like me haven’t been completely right. Here’s a chart, showing unemployment and core inflation during and after two big recessions; in each case the time series starts at the upper left.
I thought this slump would produce a “clockwise spiral” like the 80s recession, and for that matter like what happened in the 70s (not shown). That is, among other things, what textbook adaptive-expectations Phillips curves say should happen. So I thought we might well be into deflation by this point. Instead, while you can see a clockwise spiral, sort of, if you squint, it has been “scrunched” as if it’s bouncing off a hard surface at or near zero.
And that’s almost surely exactly what has happened. Downward nominal rigidity — the great difficulty of actually cutting wages and many prices — is now obvious. And research into PLOGs — prolonged large output gaps — shows that this is a general phenomenon.
So we’ve learned something about price dynamics at low inflation, and some predictions from people like me have proved somewhat wrong. That said, the world is looking a lot more like what the deflationista/liquidity trap types predicted than what the other side claimed would happen.
