The IMF released the April edition of its World Economic Outlook (WEO). One of the key analytical chapters (Chapter 3) of the Report is titled “The Dog that Didn’t Bark: Has Inflation Been Muzzled, or Was It Just Sleeping?” Its main argument (or rather sort of a mystery that needs to be resolved, in the words of its authors) is that over the course of the previous crisis episodes we used to witness severe increases in unemployment along with a simultaneous fall in inflation. Yet, during the current great recession there has been very little movement in inflation, while unemployment rates soared almost everywhere; —hence the metaphor: inflation (the dog…) does not respond (… bark). And the alleged mystery is but why?
The WEO suggests two candidates for explaining the mystery: the first one is based on the “structural unemployment has shifted” hypothesis, arguing that “the failure of inflation to fall is evidence that output gaps are small and that the large increases in unemployment are mostly structural.” The logical policy implication of this argument is that “… the monetary stimulus already in the pipeline may reduce unemployment, but only at the cost of overheating and a strong increase in inflation—just as during the 1970s”. Yet, by itself this argument does not provide much of an explanation, as the underlying causes of this structural shift still remains unanswered.
