The study looked at how inflation, inflation uncertainty, and price skewness are related in the UK. They used a model that considers different levels of price rigidity based on competition. The results show that the relationship between inflation uncertainty and price skewness forms a U-shaped pattern around the average inflation rate. This means that when inflation is at a certain level, the uncertainty and skewness of prices are highest. The findings suggest that monetary policy should target an inflation rate close to this turning point and that core inflation measures may not capture all the important information about price changes.
