The results suggest that the degree of persistence is that, while there is evidence of long‐memory behavior in the inflation rates of 17 countries, barring Russia, none of the remaining 28 countries indicate evidence of unit roots. The result implies that monetary authorities in these countries can play a role in controlling inflation, though the extent of intervention required will tend to vary, with the strongest being in Russia.en© 2018 The University of Manchester and John Wiley & Sons Ltd.
