What does the supply of labour curve show?
-Shows the ability and willingness of people to make themselves available at different wage rates.
What is a diagram that shows the supply of labour?
What is the shape and what is on the axis?
X-axis = hours worked
Y-axis = Wage rate
Flipped parabola with peak on right side.
What does the backward bending curve show?
- That at lower wages the substitution effect is greater
- At higher wages the income effect is greater.
What are the factors influencing the supply of labour?
and what is the word for it?
LEPT WN
- Legislation
- Education
- population and distribution of age
- Trade unions.
- Wages
- Non-monetary benefits
Why is there market failure in the labour market?
- Geographic immobility- When the worker cannot or will not move from an area of higher employment
- Occupational mobility - When a worker in one industry is not able to move to another due to lack of transferable skills.
What does labour immobility cause?
-Causes excess demand in one and excess supply in another.
What is the elasticity of supply of labour impacted by?
- If a high level of education is needed, people will not easily be able to take the job so supply will be inelastic.
- Time, as the long run labour supply curve is more elastic as people have time to train up
- How easily firms
What are the characteristics of contestable markets?
PPPF.
- Perfect knowledge
- Profit maximisers
- Product loyalty low
- Freedom of entry and exit.
What are the implications of contestable markets?
-Forces firms to be efficient:
- Lower prices (allocative efficient)
- Increases incentive to cut costs (x-efficient)
- Increased incentive to respond to consumer preference.
What are the types of barriers?
- Legal barriers- prevents firms for entering due to patents or rights to production.
- Advertising- can introduce brand loyalty that can stop new firms from entering.
- Pricing- limit pricing and predatory pricing can prevent firms from entering the market.
- High sunk costs
- Economies of scale
- Costs to firms leaving the market.
What are costs of leaving market?
-Leases and redundancies.
What is the degree of contestability?
-The extent to which gains to market entry exceed the costs.
What are the types of efficiency?
- Allocative efficiency
- Productive efficiency
- Dynamic efficiency
- X-inefficency.
What is allocative efficiency?
-When resources are used to produced that consumers want and value most highly and maximise social welfare.
Occurs when P=MC, this maximises utility.
What is productive efficiency?
-When firms are producing at lowest average cost so smallest amount of resources are used.
This is at the lowest point of AC curve.
Where MC=AC in short run
only possible if a firm is technically efficient.
What is dynamic efficiency?
What is needed for dynamic efficiency?
Dynamic efficiency is when resources are allocated efficiently over time. Concerned with investment which brings new production techniques.
-Competition as it requires innovation and there is also supernormal profits.
What is the diagram for dynamic efficiency?
- X axis quantity, Y axis costs
- LRAC0 above and LRAC1 below.
What is the diagram for X-inefficiency?
When a firm is not operating on the lowest point of ATC, possibly due to organisational slack or no incentive.
How to show x-inefficiency on diagram?
-X-axis quantity , Y-axis costs, show that Actual cost curve is above lowest potential cost curve.
Why does x-inefficiency happen?
-Managers have different objectives or it is a very large firm.
What are the efficiencies in a monopoly?
- not allocative as P does not equal MC
- Not productively efficient as there is no competition
- X-inefficiency could arise as there is no competition.
- Dynamic efficiency possible as there is supernormal profits.
What are the efficiencies in oligopoly?
- Productive efficiency: v unlikely/ no, few firms dominate market.
- P does not equal MC in oligopoly.
- X-inefficiency possible
- Dynamic efficiency possible.
What are the efficiencies in Perfect competition?
- Productively efficient in long run as MC=AC
- Allocative efficient
- No dynamic efficiency in long run
What are economies of scale?
-Advantages of large scale production that allows larger firms to produce at lower costs. % increase in output is greater than % increase in input.
