This study examines unfair competition among consumers according to wealth groups. The study hypothesizes that consumer groups with high income and wealth levels have a competitive advantage over consumer groups with low income and wealth levels, and therefore wealth inequality may create upward pressure on prices. Data from 37 Organisation for Economic Co-operation and Development member countries covering 2000–2022 were used in the analysis. According to the results of the analysis, increases in the wealth of high-wealth groups increase the inflation rate more severely.
