3.5 Labour Markets Flashcards
What is MRPL (Marginal Revenue Product of Labour)
MRPL = marginal physical product * marginal revenue
What does the demand curve for labour show
how many workers will be hired of any given wage rate over a given period of time
What is demad for labour derived from
The need to expand output to satisfy demand; goods need workers to make
What is the optimal wage rate
MC (marginal cost) = MRP (marginal revenue product)
How does the diminishing marginal returns affect MRPL
As workers increase, ceteris paribus, MRP will increase at first then decline
Why is the demand for labour assumed to be downward spending
- Short run fixed levels of capital so diminshing marginal returns means adding extra workers gives a lower return so they are woth a lower wage rate
- Long run, all factors of prod. vary, high wage rates will encourage businesses to use machinery instead of workers
What are the 6 main factors influencing demand for labour
- Wage Rates
- Demand for the product
- Price of other factors of production
- Wages in other countries
- Technology
- Regulation
How do wage rates influence demand for labour
same influence on demand for labour as price has on the demand for a product
Higher wage means contraction of demand
How does demand for the product influence demand for labour
if there is no demand for the product, there is no demand for the labour.
How does prices of other factors of production influence demand for labour
If machinery and equipment becomes cheap, people will switch machinery for labour and therefore the demand for labour will fall.
How do wages in other countries influence demand for labour
people will be employed in other countries as it represents a lower cost for businesses. This means that demand in the UK is low.
How does technology influence demand for labour
less demand for labour, but demand for labour in technological based industries is increasing. By 2040, about 47% of jobs could be lost to technology.
How does regulation influence demand for labour
High regulation within the labour market is likely to discourage firms from hiring since it can be very costly and time-consuming so this will reduce demand for labour in these areas
What is price elasticity of demand for labour
responsiveness of the quantity demanded of labour to the wage rate
% change in quantity demanded for labour/ % change in the wage rate
What are some factors affecting PED of labour
- PED of product
- Propotion of wages to the total cost of production
- Subsitutes
- Time
How does PED of the product affect PED of labour
If the good is elastic, then a rise in wages and hence a rise in prices for consumers will have a large impact on the quantity the business sells. This will mean that the business will reduce the number of people it employs, in order to help it make a profit.
direct correlation
How does the proprtion of wages to total costs affect PED of labour
- if wages are a huge proportion of costs, then an increase in wages will increase costs massively and so there will be a large fall in demand for labour hence it will be elastic.
direct correlation
How do substitues affect PED of labour
substitutes, such as machinery and labour in other countries, then the demand will be elastic.
This means high skilled jobs tend to be more inelastic than low skilled jobs as the labour cannot be easily replaced.
How does time affect PED
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 does the supply of labour curve represent
The labour supply is the the ability and willingness of people to make themselves available to work at different wage rates.
What are the 7 main factors affecting the supply of labour
- Wages
- Population/distribution of age
- Non-monetary benefits
- Education
- Trade unions and barriers to entry
- Wages and conditions of other jobs
- Legislation
How do wages influence the supply of labour
- Through either offering more hours or getting new workers, higher wagese wil incentivise more workers
How do population/distribution of ages influence the supply of labour
- High population ensures large supply
- Distribution of age is important to also ensure this
- Migration rienforces working force (75% of child-bearing age) and boost young people
How does non-monetary benefits influence the supply of labour
- Supply will increase from high job satisfaction
- this may be due to being close to family or offer perks like free healthcare/ flexible hours
