3.5.1-2 Demand and Supply of labour Flashcards
Define derived demand
Derived Demand is when the demand for a commodity/ service is due to the demand for a good.
Define MPP (Marginal Physical Product of labour)
This is each additional good produced for each additional unit of labour.
What is the law of diminishing returns?
Where each good consumed produces the same amount of satisfaction up to a point where the level of satisfaction decreases for each additional good consumed.
Define MRP (Marginal Revenue Product of labour)
The extra revenue produced per each additional unit of labour. MRP = MPP x MR
What is Marginal Productivity theory?
The theory that a firm will employ labour up until the point where MR = MC of the extra worker. This means that the firm are profit maximising.
Identify 4 factors that would shift the demand curve for labour
- If the price of the end product increases
- If there is a fall in the non-wage costs of production
- A decrease in the price of capital that replaces labour
- An improvement in labour productivity
What is the formula for calculating MP if you are given a table?
Change in total product / change in labour
Identify 4 factors that would affect elasticity of demand for labour.
- Availability of capital that could replace labour
- Price elasticity of the end good
- Labour cost as a % of total costs
- Time
Using the MRP theory explain why a footballer gets paid more than a plumber
A footballer has a higher more rare skillset in a very competitive market compared to a plumber. A plumber could also be easily replaced in comparison to a footballer. The footballer will sell shirts and tickets so the extra revenue gained is higher than the plumber.
What is the relationship between leisure time and work?
They are substitutes.
What is the opportunity cost of 1 hour of work?
1 hour of leisure
What is meant by the substitution effect of a wage increase?
For people with a lower wage, the increase in wage rate will motivate them to work for longer/
What is meant by the income effect of a wage increase?
For people with a higher wage, the increase in wage will demotivate them to work as they are earning more money for less time worked.
Why might an individuals supply of labour be backward bending?
This is where the income effect outweighs the substitution effect. The more the wage rises, the less labour the individual supplies.
What is the supply curve of labour also known as?
The Average Cost curve of labour - this shows us how many workers will be prepared to supply labour at each wage rate and therefore. The average wage rate is = to the average cost of the firm.
