In a perfectly competitive labour market, the equilibrium wage rate and the level of employment are determined by the interaction of the supply and demand for labour. Demand for labour is derived from the marginal product of labour (MPL). Firms will hire labour up to the point where the additional output generated by a worker (MPL) equals the wage rate. A higher wage rate makes it more expensive to employ labour, leading to a decrease in demand.

Supply of labour is represented by the number of workers willing and able to work at different wage rates. Higher wages incentivize more people to enter the labour market, increasing the supply of labour.

The equilibrium occurs where the quantity of labour supplied equals the quantity of labour demanded. At this point, the market clears, and there is no surplus or shortage of labour. The corresponding wage rate is the equilibrium wage, and the corresponding level of employment is the equilibrium level of employment.

If the wage rate is above the equilibrium level, a surplus of labour will exist, leading to downward pressure on wages. Conversely, if the wage rate is below the equilibrium level, a shortage of labour will exist, leading to upward pressure on wages.
