The Labour Market Flashcards
Demand for Labour
The demand for labour is a derived demand (a demand resulting from demand for something else) from demand for goods and services that labour can produce. Labour is only employed if they provide a net benefit to the firm.
Marginal productivity of labour
MRP = the additional revenue from hiring one more worker.
Firms should only employ workers that increase revenue by a greater amount than their cost to the firm.
According to marginal productivity theory, MRP of labour determines the demand for labour.
MRP Labour
MRP= MPP x MR
Elasticity of demand for labour
A measure of how much demand for labour changes as wages change.
= % change in the quantity of labour demanded / % change in the wage rate.
More elastic in the LR as there’s more time to find a replacement worker.
Easier to replace a worker = more elastic demand.
The more price elastic the demand for the product is, the more elastic the demand for labour will be.
Factors affecting labour demand
- How easily labour can be swapped for capital.
- How much waged make up total cost.
Marginal cost of labour
The change in total labour costs from employing one extra worker
Market equilibrium wage
Firms will employ workers as long as the extra revenue the workers generate from producing goods and services is greater than the cost of employing them. The market equilibrium wage is where MRP=MC.
Factors shifting labour demand
- Increased gov regulation
- New technology
- Level of education
- Change in demand for a product
- Number of rims producing a product
Wage increase and productivity
Ceteris Paribus, if wages rise, the quantity demanded for labour decreases, the same as for goods and services.
Competitiveness
High labour costs per unit imply that a firm has low labour productivity. If a firm can boost labour productivity and reduce labour costs per unit, that firm will boost its competitiveness.
Factors that cause a shift in the MRP of labour curve
- changes in labour productivity
- rising labour cots
- a good/service’s price
Individual labour supply
The number of working hours labour are willing to work at a particular wage rate for a job. If wages rise workers are incentivised to work longer hours.
Occupational labour supply
The number of employees who will work at their wage rate. The supply curve for occupational labour is upward sloping.
Non-monetary considerations for labour
Both monetary and non-monetary considerations affect supply of labour. Non-monetary considerations are the benefits a job offers on top of the wage (monetary) that attract prospective workers.
- Net advantage
- Monetary factors = wages
- Non-monetary factors: free food, dental care, gym facilities, training, job satisfaction.
Backward bending supply curve
A theory in which after a certain point, rising wages lead to a reduction in labour supplied.
- initially as wages rise it becomes more valuable to work rather than to take leisure, due to the substitution effect of work becoming more beneficial.
- After wage W, the benefit of the extra money earned diminishes and instead labour chooses to take more leisure than work as long. This is due to the income effect.
The labour supply curve
The labour supply curve is upward sloping. Higher prices (wages in this case) lead to a higher quantity of labour being supplied. Many things can shift the labour supply curve:
- Government policies
- Level of education
- Wage rates
- Quality of job advertising
- Number of workers
The Elasticity of Labour Supply
- Elastic in low-skilled jobs. Small wage rate increases will result in large increases in quantity supplied.
- Supply is more elastic if workers are mobile.
- Often inelastic in skilled jobs. Takes a long time to train, while supply may change in the long term, it won’t in the short term.
Economic rent
Economic rent is an excess payment made to or for a factor of production over and above the amount expected by its owner. As supply gets more elastic, economic rent reduces to zero (as the labour market for this particular job becomes more competitive).
Transfer earnings
Every worker has a minimum amount that they are willing to accept to stay in their current job (and not switch to another job). This minimum amount of money is called transfer earnings.
Wage differentials
Wage differentials is described as the difference in wages between workers with different skills in the same industry, or between workers with comparable skills in different industries or localities.
Factors causing wage differentials
- Skill differences
- Location
- Trade unions
- Industry
- Location
- Monopsony
The model of wage determination
In a perfectly competitive labour market, wages are determined by the forces of demand and supply. In this type of market firms are price-takers so they don’t have control over the wage they pay. This wage is = to the MC and AC for the firm because the supply is perfectly elastic for an individuals firm’s labour.
Wage
The sum of economic rent and transfer earnings.
Imperfections in the labour market
- Imperfect information
- Trade unions
- Labour immobility
