Give three reasons why wage differentials between occupations persist.

Occupations differ in the skill and training they demand, in the marginal revenue product of the work, and in how attractive the job is in non-monetary terms.

What is a compensating wage differential?

It is the extra pay needed to attract workers into unpleasant, dangerous or unsocial work that would otherwise be avoided at the going wage.

How does imperfect information create wage differentials between identical workers?

Workers do not know every vacancy and every rate of pay on offer, so equally skilled people can end up earning different amounts in different firms.

How does geographical immobility sustain regional wage differentials?

Housing costs, family ties and the expense of moving stop workers relocating to better-paid regions, so the gap is never competed away.

Questions from this subtopic

Each one with the model answer underneath.

1
Define a wage differential.
Model answer
A wage differential is a difference in the wage rates paid to different workers, occupations, industries, regions or groups.
2
Give three reasons why wage differentials between occupations persist.
Model answer
Occupations differ in the skill and training they demand, in the marginal revenue product of the work, and in how attractive the job is in non-monetary terms.
3
What is a compensating wage differential?
Model answer
It is the extra pay needed to attract workers into unpleasant, dangerous or unsocial work that would otherwise be avoided at the going wage.
4
How does imperfect information create wage differentials between identical workers?
Model answer
Workers do not know every vacancy and every rate of pay on offer, so equally skilled people can end up earning different amounts in different firms.
5
How does geographical immobility sustain regional wage differentials?
Model answer
Housing costs, family ties and the expense of moving stop workers relocating to better-paid regions, so the gap is never competed away.
6
Distinguish between geographical and occupational mobility of labour.
Model answer
Geographical mobility is the ability of workers to move between locations to take work, while occupational mobility is their ability to move between different types of job.
