It’s the rule, writes Christy Romer:
The regime shift we are seeing in Japan is just the kind of bold action that might actually succeed in changing both inflation and growth expectations a substantial amount. As a result, it may be an effective tool for encouraging robust recovery and an end to deflation.
Nick Rowe has been saying that for a while but, before we get too gung-ho, Romer cautions:
I don’t know if the Japanese experiment with monetary regime change will work. But I am confident that we will learn a great deal because they had the nerve to try.
