''Inflation persistence in Europe: the effects of the covid-19 pandemic and of the Russia-Ukraine war''
( 2023, Vol. 43 No.1 )
 
 
This note analyses the possible effects of the Covid-19 pandemic and of the Russia-Ukraine war on the degree of inflation persistence in both the euro zone and the European Union as a whole (EU27). For this purpose a fractional integration model is estimated, first for the full sample and then using recursive and rolling methods. Although the two latter methods provide evidence of a significant increase in inflation persistence (at least in the case of the EU27, for which in addition to jumps an upward trend is clearly identifiable), the full-sample results imply long-lasting but only temporary effects of the two shocks being examined. These findings suggest that the required policy response to both shocks should also have a temporary nature.
