The article examines how inflation affects the variability of prices in Australia using survey-based inflation expectations. They found that unexpected inflation increases price variability, with no difference between positive and negative inflation shocks. There is a J-shaped relationship between unexpected inflation and price variability, while expected inflation doesn't show a specific pattern. The study also identified two time periods where the relationship between inflation and price variability changed. Overall, the traditional approach to measuring inflation expectations works well in understanding the inflation-price variability relationship in Australia.
