In a nutshell
- The global inflation episode of 2021-23 highlighted, once again, the importance of understanding the sources of inflation, especially in developing countries.
- The poorest income quintiles are disproportionately affected by rising prices. Hence, these low-income groups face a double burden: as employees, their wages contribute the least to inflation, and as members of the most disadvantaged social strata, they experience a greater impact from inflation than the average income earner.
- There is suggestive evidence of a positive relationship between the extent of inflation due to profits per unit of capital and market concentration. This suggests that policies promoting competition can be important in mitigating inflationary pressures.
