3.1.5.4 The labour market

The labour market: the basics

A market is any situation where buyers and sellers interact. In a product market, consumers buy goods and services from firms. In the labour market, firms “buy” labour by hiring workers, and workers “sell” their time, effort and skills.

In this market:

• Firms demand labour because workers help produce goods and services.
• Workers supply labour because they want income and other rewards from work.
• The wage is the payment workers receive for labour.

A supermarket such as Tesco demands checkout staff, delivery drivers and managers because it needs workers to sell groceries. Workers supply their labour if the wage and conditions make the job worthwhile.

Demand for labour

Demand for labour usually slopes downwards: as wages rise, labour becomes more expensive, so firms may hire fewer workers, reduce overtime, or invest in labour-saving technology.

Demand for labour is often derived demand. This means it comes from demand for the final good or service the worker helps produce. For example, if demand for home deliveries rises, supermarkets and delivery firms may demand more drivers.

Supply of labour

Supply of labour usually slopes upwards: as wages rise, more people may be attracted into that job, work more hours, or train for that occupation.

For example, if wages for electricians rise, more people may choose apprenticeships in electrical work, though this takes time because training is needed.

Wage determination using supply and demand

In a simple labour market, wages are determined where demand for labour equals supply of labour. This point is called the equilibrium.

The diagram below shows how a labour market works. The vertical axis shows the wage rate, and the horizontal axis shows the quantity of labour. A rise in demand for labour shifts the demand curve to the right, increasing both the equilibrium wage and employment.

What can shift demand for labour?

Demand for labour can increase when:

• Demand for the product rises, such as more demand for online shopping increasing demand for delivery drivers.
• Workers become more productive, so each worker adds more value to the firm.
• A sector expands, such as renewable energy creating demand for engineers and technicians.
• Firms need scarce skills, such as coding, data analysis or cyber-security.

Demand for labour can decrease when:

• Demand for the product falls.
• A firm replaces some workers with machines or software.
• Production moves abroad.

What can shift supply of labour?

Supply of labour can increase when:

• Wages rise and attract more workers.
• Training and qualifications become more available.
• Migration increases the number of available workers.
• More people choose to enter that occupation.

Supply of labour can decrease when:

• Workers retire or leave the labour force.
• Fewer people train for that job.
• Working conditions are unattractive.
• Migration rules reduce the number of available workers.

Brexit affected some UK labour markets by reducing the supply of EU workers in areas such as hospitality, agriculture and social care. COVID-19 also changed labour supply because some people left certain sectors, became economically inactive, or changed their work preferences.

Wage differentials

Wage differentials happen because labour is not all the same. Workers have different skills, qualifications, experience and productivity. Jobs also differ in responsibility, risk, working conditions and how scarce the required skills are.

Wage differentials between occupations

Wages often differ between occupations. For example, a surgeon is usually paid more than a retail assistant because the job requires many years of training, high responsibility, scarce skills and intense pressure.

Common causes include:

• Skill and qualifications: jobs needing specialist training often pay more.
• Experience and productivity: more productive workers may generate more revenue for firms.
• Risk and responsibility: dangerous or high-pressure jobs may need higher wages to attract workers.
• Scarcity of labour: if few workers have the right skills, supply is limited, so wages can be higher.
• Demand for the final product: if demand for a service is high, demand for workers in that sector may rise.
• Trade unions and bargaining power: some workers can negotiate better pay and conditions.

Wage differentials within occupations

Wages can also differ within the same occupation. Two teachers, nurses, chefs or software developers may not earn the same wage.

This can happen because of:

• Experience or seniority.
• Location, such as London weighting.
• Overtime, unsocial hours or shift work.
• Performance-related pay.
• Different employers, such as small firms compared with large firms.
• Discrimination, although unequal pay based on protected characteristics such as sex or race is illegal and unethical.

Ethical issues in the labour market

Labour markets are not just about efficiency and profit. Pay affects people’s living standards, motivation and wellbeing.

Firms may want to keep labour costs low to increase profits, but very low pay can create in-work poverty, especially during periods like the 2022–23 cost-of-living squeeze. Governments may respond with policies such as increases in the National Minimum Wage or National Living Wage, though firms may argue that higher wage costs can increase prices or reduce hiring.

Pay gaps can also raise moral and ethical concerns. If workers doing equal work are paid differently because of discrimination, this is unfair and illegal. Even when differences are legal, society may still debate whether very large wage gaps are acceptable.

Gross pay and net pay

When you get paid, there is a difference between the amount you earn before deductions and the amount you actually take home.

Common deductions include:

• Income tax.
• National Insurance contributions.
• Pension contributions.
• Student loan repayments, if relevant.
• Other deductions agreed with the employer.

For GCSE Economics, you do not need complicated tax rules unless the question gives them. Use the information in the question carefully.

Calculating gross pay

Gross pay can be calculated in different ways depending on how the worker is paid.

For hourly pay:

Gross pay = hours worked × hourly wage

For a salary:

Monthly gross pay = annual salary divided by 12

For overtime, add the overtime pay to normal pay.

Calculating net pay

Net pay is calculated by subtracting deductions from gross pay:

Net pay = gross pay − total deductions

Bringing it together

The labour market is part of the wider economy because wages affect both firms and households.

For workers, wages are a major source of income and influence living standards. For firms, wages are a cost of production. If wages rise, workers may benefit from higher incomes, but firms may face higher costs and may raise prices, reduce profits or hire fewer workers.

This is why labour-market questions often involve trade-offs. A higher minimum wage may improve fairness and reduce poverty for some workers, but it may also increase costs for businesses such as cafés, care homes or small retailers. A balanced answer explains both sides before reaching a judgement.
