Compensating differential

From Wikipedia, the free encyclopedia

Compensating differential is a term used in labor economics to analyze the relation between the wage rate and the unpleasantness, risk, or other undesirable attributes of a particular job. A compensating differential, which is also called a compensating wage differential or an equalizing difference, is defined as the additional amount of income that a given worker must be offered in order to motivate them to accept a given undesirable job, relative to other jobs that worker could perform.^[1][2] One can also speak of the compensating differential for an especially desirable job, or one that provides special benefits, but in this case the differential would be negative: that is, a given worker would be willing to accept a lower wage for an especially desirable job, relative to other jobs.^[3]

The idea of compensating differentials has been used to analyze issues such as the risk of future unemployment,^[4] the risk of injury,^[5] the risk of unsafe sex,^[6] and the monetary value workers place on their own lives.^[7]

[edit] Possible confusion with other concepts

The terms compensation differential, pay differential, and wage differential are also used in economics, but normally have a different meaning. They simply refer to differences in total pay (or the wage rate) in any context.^[8] So a 'compensation differential' can be explained by many factors, such as differences in the skills of the workers in those jobs, the country or geographical area in which those jobs are performed, or the characteristics of the jobs themselves. A 'compensating differential', in contrast, refers only to differences in pay due to differences in the jobs themselves, for a given worker (or for two identical workers).

In the theory of price indices, economists also use the term compensating variation, which is yet another unrelated concept. A 'compensating variation' is the change in wealth required to leave a consumer's well-being unchanged when prices change.
