3.5 Labour Markets Flashcards
What does the demand curve for labour show
The quantity of labour there employers would wish to hire at each possible wage rate. The demand for labour is determined by the marginal revenue product - the extra revenue generated by an individual worker.
MRP =
marginal output x price OR the difference in total revenue
What is derived demand
The demand for labour is derived demand as it is derived from demand for the product the labour produces. Businesses only want the worker for as long as people are willing and able to buy the product they produce.
Factors influencing demand for labour:
(Greater detail on page 2-3)
Wage rates
Demand for the product
Prices of other factors of production
Wages in other countries
Tech
Regulations
(Also the state of the economy)
What is the price elasticity of demand of labour
This is the responsiveness of the quantity demanded of labour to the wage rate.
Factors affecting PED of labour:
-directly correlated to the price elasticity of demand for the product.
-it is affected by the proportion of wages to the total cost of production
-if there are many substitutes such as machinery and labour in other countries then the demand will be elastic.
-time also play a role: in the long run it is more elastic as machinery can be developed and jobs can be moved whilst in the short run firms have to employ workers and redundancy payments can be expensive.
What is supply of labour
The supply of labour curve shows the ability and willingness of people to make themselves available to work at different wage rates
Factors influencing supply of labour:
(More information on page 4)
- wages
-population and distribution of age
-non-monetary benefits
-eduction/qualifications/training
-trade unions and barriers to entry
-wages and condition of other jobs
-legislation
Market failure: how labour should act
The labour market should operate in the same way as any other. An increase in wages should attract labour to the industry and a fall in labour should mean labour leaves industry. However, labour is not a perfect free market
Market failure - immobility:
- labour can suffer form either occupation or geographical immobility
- immobility can mean that there can be excess supply of labour in one area and excess demand in another. Even if wages are higher where there is excess demand, people will be unable to leave where there is excess supply to get a job in that area/occupation
Occupational immobility
Where workers find it difficult to move form one job to another as there is a lack of transferable skills. It is partially difficult in the short term when workers need to get new training but in the long run it may only be possible at a high cost.
Geographical immobility
Where they find it difficult to move form one place to another due to costs of movement, family etc. There may be no jobs in one place nut jobs in another. It would be expensive to attend interviews, they would have to leave their family behind and may not know about vacancies. Housing is also a big issue (those on lower incomes are more geographically immobile)
Factors affecting Elasticity of supply:
- it depends on the level of qualifications and training - also depends on the availability of suitable labour in other industries (poaching workers from other industries).
- it depends on time as in long run supply of labour will be more elastic as people will have time to train,
-If a job is vocational, it will be inelastic since even if wages fall people won’t leave the job.
What is elasticity of supply
The responsiveness of supply to a change in wage rates
How do wage rates differ
Differ within occupational due to age, education, training, work experience, skill/talent/ability to perform tasks, sex and ethnic background (last two are illegal). For the highest paid there will still be a low supply and a high MRP.
What does the immobility of labour mean for wage determination
There may be excess supply in one area/occupation causing Lew wages and not enough worker in another meaning higher wages.
