This study examines the drivers of inflation levels, inflation variability, and growth variability collectively representing long-term central bank performance across 37 advanced economies in the Great Moderation era. A key finding is that central bank performance is consistently linked to the overall quality of institutions, while central bank-specific factors such as independence, exchange rate regimes, or inflation targeting show no significant impact. The analysis is extended to the 2022 inflation resurgence, using pre-2022 country characteristics. The results indicate that reliance on imports from Russia (likely gas) and its interaction with post-COVID GDP growth are the primary determinants, suggesting that the inflation surge was not a reversal of the Great Moderation.
