The canonical example here is Japan, where many are persuaded that the key mistake it made was to slip into deflation, which has persisted and held back growth. A closer look at the Japanese experience suggests that it is by no means clear that its growth has been slower than warranted let alone that deflation caused slow growth.
It is true that after its devastating crisis in the early 1990s, Japan may have prolonged the slowdown by not taking early action to clean up its banking system or restructure over-indebted corporations.
