Abstract: The paper deals with the method of decomposition of the rate of change of a chained price index into the sum of the effects of the item groups covered by the index, as suggested by M.Ribe (1999). The aim is twofold: firstly, to provide a generalization of the envisaged method to the case of the decomposition of the average rates of change of the aggregate index over different time intervals (such as, for example, annual or quarterly average rates of change); secondly, to investigate the formal properties of the decomposition in order to evaluate its interpretative effectiveness as a measure of the impact of the evolution of the prices of different components on the overall inflation.
