Labour market

The Labour Market

The labour market is a factor market where workers (suppliers of labour) and employers (demanders of labour) interact to determine wages and employment levels. Like any market, the wage rate (the price of labour) is determined by the interaction of supply and demand.

• Demand for labour comes from employers. It is a derived demand — firms hire labour because they need it to produce goods and services consumers want. As wages rise, quantity of labour demanded falls (more expensive to employ workers).
• Supply of labour comes from workers. As wages rise, more people are willing to offer their labour — higher wages attract more workers into the labour market or induce existing workers to offer more hours.

The equilibrium wage is where labour supply equals labour demand. At this wage, the number of workers willing to work equals the number employers want to hire.

Wage Differentials

Wages vary considerably between and within occupations. Key factors explaining wage differentials include:

• Skills and qualifications — highly skilled workers (surgeons, specialist engineers) are scarce relative to demand → high wages. Low-skill roles (basic retail, cleaning) have large labour supply → lower wages.
• Productivity — more productive workers are worth more to employers and command higher wages.
• Trade union strength — unionised workers can collectively bargain for higher wages than non-unionised workers in comparable roles.
• Working conditions — unpleasant, dangerous, or unsociable jobs (offshore oil work, night shifts) must offer compensating wage differentials to attract workers.
• Discrimination — gender, ethnic, and other forms of discrimination cause pay gaps that are not explained by productivity differences.
• Geographical factors — wages tend to be higher in cities (especially London) where cost of living and labour demand are greater.

Gross Pay and Net Pay

Gross pay is the total wage or salary earned before any deductions.

Net pay (take-home pay) is what the worker actually receives after deductions:

• Income tax — a direct tax on earnings above the personal allowance (£12,570 in 2024/25). Basic rate: 20%; Higher rate: 40% on earnings above £50,270.
• National Insurance (NI) contributions — paid by employees on earnings above a threshold. Funds the NHS, state pension, and other social security benefits.
• Other deductions may include: pension contributions, student loan repayments, workplace benefits.

Net pay = Gross pay − Income tax − National Insurance − other deductions
