HookThe £3.60 experiment nobody thought would work
On 1 April 1999 Britain ran a live experiment on its own labour market: the first National Minimum Wage, set at £3.60 an hour for adults. Employers' groups and plenty of economists warned of substantial job losses — textbook supply and demand says a wage floor above equilibrium must price workers out. The Low Pay Commission then spent two decades checking, study after study, and found little or no detectable damage to employment. The floor kept rising; the jobs kept coming.
By April 2024 the successor National Living Wage stood at £11.44 and covered workers from age 21 — among the highest minimum wages relative to typical pay of any rich economy — and in February 2021 the Supreme Court ruled that Uber's drivers were 'workers' entitled to it, dragging the gig economy inside the fence. This section is the labour side of globalisation: where the jobs moved, why an hour of work is priced at £11.44 in Leeds and well under £1 in Dhaka, and what actually happens when governments write a price floor into law.
ModelEmployment patterns — where the jobs went
Rich economies have spent fifty years shifting employment out of making things and into services. UK manufacturing employed around 7 million people in the late 1970s; today the figure is roughly 2.6 million, while services account for over 80% of jobs. Much of the work did not vanish — it moved: China became the world's factory, and Bangladesh's ready-made garment industry grew from almost nothing in 1980 to around 4 million workers, most of them women. The quiet revolution alongside the sectoral shift is participation: the UK female employment rate has risen from roughly 53% in 1971 to around 72% today, transforming household incomes and the composition of the workforce alike.
Migration is the second great pattern. When eight Central and Eastern European states joined the EU in 2004, the UK was one of only three members to open its labour market immediately; the government's advance estimate was famously around 13,000 arrivals a year, and several hundred thousand workers came within a few years, reshaping food processing, hospitality and construction.
The newest pattern is the gig economy: app-mediated, task-by-task work. Uber launched in London in 2012 and by the early 2020s reported around 100,000 UK drivers and couriers; add Deliveroo, Amazon Flex and their rivals and gig work is now a structural feature of the labour market — flexible for some, precarious for others, and legally contested, as the 2021 Supreme Court ruling showed.
ModelWage rates — what sets the price of an hour
Wages are prices, set where labour demand meets labour supply. Demand for labour is derived demand — nobody hires a barista for the joy of it; they hire because customers buy coffee — and it rises with the worker's productivity: what an hour of work adds to revenue. Supply depends on how scarce the skills are: surgeons out-earn baristas because few people can do the work and training takes a decade.
Between countries the gaps are staggering, and productivity explains most of them. A full-time UK worker on the National Living Wage earns about £1,860 a month (£11.44 × 37.5 hours × 52 weeks ÷ 12); Bangladesh's garment minimum wage, raised after violent protests in December 2023, is 12,500 taka — roughly £90 a month, or somewhere around 45p an hour. The difference is not mainly employer generosity or its absence: the UK worker operates with vastly more capital per head — machinery, software, infrastructure, institutions — and so produces correspondingly more value per hour worked.
Migration links the two ends: workers moving from low-wage to high-wage economies raise their own productivity overnight by plugging into richer capital, and the remittances they send home now dwarf foreign aid flows — over $600bn a year to developing countries, worth roughly a quarter of GDP in Nepal and around a tenth in the Philippines.
MechanismMinimum wage legislation — the floor and the evidence
The competitive model's prediction: set a wage floor above equilibrium and demand for labour contracts while supply expands — excess supply of labour, meaning unemployment concentrated among the lowest-skilled. That is the diagram Edexcel expects you to draw and label.
The UK evidence complicated the story. The Low Pay Commission's research programme, reviewing the minimum wage's first two decades, found employment effects close to zero. Two explanations matter for essays. First, monopsony: where a dominant local employer faces little competition for staff, it can pay below the competitive wage — and a legal floor can then raise pay AND employment simultaneously. Second, firms adjust on other margins: trimming hours, nudging prices up, accepting thinner margins, or investing in automation and training so productivity rises to meet the wage.
The honest caveat: evidence of no damage at past levels does not prove safety at any level. With the National Living Wage now targeting two-thirds of median earnings — close to the international frontier — the Low Pay Commission itself treads carefully. And enforcement matters as much as the rate: the 2021 Uber ruling showed the floor only protects workers the law can see.
DataWhat a 9.8% rise does to a wage bill
Minimum wage questions in Paper 3 extracts usually arrive as employer arithmetic: a rise is announced, a small firm's costs jump, and you are asked to analyse the responses. Run the numbers before the theory — the calculation is where the application marks sit, and it disciplines everything you argue afterwards, protecting you from the classic error of asserting that 'costs rise' without ever saying by how much, for whom, or relative to what.
In April 2024 the National Living Wage rose from £10.42 to £11.44 — an increase of £1.02, or £1.02 ÷ £10.42 ≈ 9.8%. Take a café employing 12 staff at the NLW for 30 hours a week. Weekly wage bill before: 12 × 30 × £10.42 = £3,751.20. After: 12 × 30 × £11.44 = £4,118.40. The rise is £367.20 a week — about £19,094 over a year (£367.20 × 52). The café's menu of responses is your analysis: raise prices (how price-elastic are flat whites?), cut hours or staffing (the textbook effect), automate ordering, lift productivity, or absorb the hit in margin. Which response dominates depends on local competition and the elasticity of demand — which is your evaluation, ready-made.

ExamWhat examiners want
Draw the labour market diagram whenever the question allows: supply, demand, the wage floor above equilibrium, excess supply clearly labelled. Then do what most candidates never do — evaluate the diagram itself, using monopsony and the Low Pay Commission's evidence. Edexcel B rewards testing models against data, and 3.5 offers the clearest chance in Theme 3. Quote figures with dates: £3.60 in April 1999, £11.44 from April 2024, the February 2021 Uber ruling.
On wage-gap questions, resist moral language and give the mechanism: capital per worker, productivity, institutions. And on minimum wage essays the strongest evaluation is that THE LEVEL IS THE ARGUMENT — a floor at 30% of median pay is uncontroversial, one at two-thirds carries genuine risk, and the Low Pay Commission's own caution is your quotable authority.
