Unraveling the Dynamics of Inflation Persistence: A Long-Memory Analysis of Headline Inflation Convergence and Divergence in European Economies

Summary/Abstract: This comprehensive study delves into the Harmonised Consumer Price Index (HCPI) behavior across Europeaneconomies from the early 2000s to the post-pandemic period. By analyzing the patterns of convergence anddivergence in HCPI persistence, the study aims to uncover the common external and country-specific fac-tors driving these dynamics. Utilizing the local Whittle estimation method, the research examines the long-memory properties of headline inflation through monthly data from January 1996 to January 2023. The studyexpands upon existing knowledge of inflation persistence by exploring its changes and the various patternsof inflation persistence in Europe. The findings reveal significant differences in the persistence of inflation andthe underlying factors behind it. As such, the study emphasizes the need for tailored policy approaches and adeeper understanding of inflation's true nature, expectation formation, price-setting behavior, and monetarypolicy in shaping inflation persistence. Given its important policy implications, this research is highly relevantto the European Central Bank (ECB) and national governments within the Eurozone
