CoinWorld reports that according to "Federal Reserve mouthpiece" Nick Timiraos's tweet: Federal Reserve research shows that the inflation mechanism in developed economies may have changed post-pandemic: more categories experiencing price increases of over 3%, with widespread wage growth in the service sector becoming a key driver; even categories with stable or falling prices no longer pull down overall inflation as they did before; pre-pandemic models have continued to underestimate current inflation levels, indicating that the relationship between price dispersion and overall inflation may have shifted.
