We find that this autocorrelation in monthly inflation leads to significant persistence in the headline … annual inflation figure. A one-off shock to monthly inflation will have an effect on the headline figure equal to 10% of the …

We apply classical econometric method to characterize the dynamic behavior of the quarter-on-quarter inflation over the … inflation series and as well as for the consumer price inflation at representative product groups level, taking into account the … influence of structural breaks in the mean of inflation on the level of persistence.
