Cost of living vs. salary levels
Applying cost of living as a salary level determinant is somewhat controversial.
They are as different as apples and oranges.
| Salary levels | Cost of living |
|---|---|
| Salary levels are a function of the supply of and demand for labor. | The cost of living is a function of the supply of and demand for goods and services. |
The two may move in the same or opposite directions as they function independently. Thus, one geographic region may have a high salary level and a low cost of living, while another may have the exact opposite conditions.
Overall, the correlation of changes in salaries with the cost of living is less than 10%.
Measuring the cost of living
Employers may still use cost of living as one salary determinant, since tying salaries to changes in the cost of living provides a measure of fairness to employees by assuring them that their real salaries are not devalued.
But using the cost of living as a determinant also implies a constant standard of living. Historically, unions have opposed the principle for this reason.
Methods that provide the same absolute cost-of-living adjustment for all employees may actually impair fairness to employees.
Such flat adjustments imply that everyone's cost of living:
- is the same
AND
- has changed by the same amount.
Unfortunately, technical problems in measuring changes in the cost of living may make such effects inequitable.
