Krugman argues that Japan was only the first of the major economies to succumb to chronic deflation, back in the 1990s, and has now been followed by the European Union, China, and most recently Switzerland, with its soaring franc and falling prices. The US, in this view, remains near the vortex as well, prompting the Keynesians’ repeated calls for more fiscal stimulus, which, unlike monetary policy, is seen by the pessimists to be especially efficacious at the ZLB.
