, 12.3 A perfectly competitive labour market
Requirements for perfect competition
Large number of buyers and sellers
All particulars are wage takers
Labour must be homogenous – identical skills
Workers must be completely mobile – move freely from 1 employer to
another
No government intervention
All participants have perfect knowledge – full information access
There must be perfect competition in the goods market
Equilibrium in a perfectly competitive labour market
At equilibrium there is no
unemployment
Equilibrium is determined by interaction
between demand for labour and supply
of labour
The equilibrium wage rate = We
Equilibrium quantity = Ne
Individual supply of labour
Each individual decides how to divide time between work and leisure
Quantity of labour supplied (no. of working hours offered by a worker) tends to
rise as the wage rate rises, but only up to a certain point
Substitution effect
As the wage rate increases, workers will work more hours, substituting leisure
time to gain higher wages
Graph points A to B
Income effect
Leisure is a normal good, so as income rises workers want more leisure time
Increase in wages = decrease in hours worked
Graph points B to C
