Krugman, Paul.
I’ve been writing for a long time about how the euro area needs more inflation. But I suspect that many readers don’t quite see how this ties into the macro story. So here’s something that may or may not clear things up — a stylized little model linking euro inflation and the adjustment problem to overall monetary policy. It’s very stylized, making some obviously untrue but I think still useful assumptions, and I have been finding that it clarifies my own thinking, at any rate.
