Martin Wolf on Inflation and stagflation

All this would undermine elevated asset markets and might trigger worries over debt sustainability. In a still fragile world economy, the results might be ugly. One might even see a return to the stagflation of the 1970s, with far lower inflation, but also far higher indebtedness.

The starting point is a puzzle: why is inflation so low when the rate of unemployment is already a little below the level the Fed (and most economists) consider to be “full employment”
(the rate at which inflation should start to accelerate upwards).
