Syllabus points

What is unemployment?

A labour market where the wage sits above the level that would clear it. More people want to work at that wage than firms will hire, and the gap between the two quantities is the unemployment.

The unemployed are people of working age who are able and willing to work, actively seeking work, but without a job.

All parts of that definition matter. Someone who has stopped looking, or is not able to work, is not counted as unemployed; they are economically inactive.

Unemployment rate = (number unemployed ÷ labour force) × 100

The labour force is everyone employed plus everyone unemployed. It does not include students, retired people, carers or the long-term sick.

Dividing by the total population, or by the working-age population, is the classic error. The denominator is the labour force.

Measuring unemployment

Two methods, and the syllabus expects both:

Both measures miss hidden unemployment: discouraged workers who have given up looking, and people in part-time work who want full-time hours.

Types of unemployment

Diagram walkthrough · 2 minCyclical unemployment as a chain, not a labelEconplusDalTwo separate routes from one aggregate demand shift, which is what a question asking you to explain rather than define is after. Labour is a derived demand, so when demand for goods and services falls, demand for the workers who make them falls with it. Firms are also selling less, so revenue falls, and because labour is their largest cost they cut jobs to hold profit margins. It also settles the naming: cyclical for the downturn, demand deficient for the cause.

Identifying the type is what decides which policy will work.

TypeCauseExample
Cyclical (demand-deficient)A downturn in the economy: total demand fallsWorkers laid off during a recession
StructuralLong-term change in the pattern of demand or technology; skills no longer match jobsCoal miners after pit closures
FrictionalPeople between jobs, searching for the right oneA graduate looking for a first job
SeasonalDemand varies through the yearSki instructors in summer; farm workers out of season
VoluntaryChoosing not to accept available work at current wagesSomeone holding out for a better offer

Only cyclical unemployment responds to demand-side policy. Structural unemployment needs retraining and improved mobility, pumping demand into the economy will not help someone whose skills no longer match any vacancy.

Frictional unemployment is not really a problem. Some job searching is healthy: it helps people find work that suits them.

Policies to reduce unemployment

Type of unemploymentAppropriate policy
CyclicalExpansionary fiscal policy (4.3) or lower interest rates (4.4) to raise demand
StructuralRetraining, education, relocation support, regional investment
FrictionalBetter job information and employment services
SeasonalEncouraging year-round industries; diversification

Worked example

A country's largest steelworks closes. Two thousand workers lose their jobs in a town where most other employers want different skills.

The workers' skills match steel production, not the jobs available → they are occupationally immobile (1.2) → moving elsewhere may be impossible if housing is expensive, so they are also geographically immobile → this is structural unemployment.

Why demand-side policy fails here: cutting interest rates raises demand across the economy, but the vacancies created need different skills or are in different regions. The steelworkers remain unemployed while those vacancies go unfilled.

What would work: government-funded retraining in skills local employers actually need, plus help with relocation costs. Both take time and money, and the training must match real vacancies, otherwise it wastes resources and the workers are no better off.

Common exam mistakes

Exam technique

Identify the type first. The stimulus almost always contains the clue, a recession points to cyclical, a closing industry to structural, someone between jobs to frictional. Then match the policy and say why the alternative would not work.

For consequences, organise by group: the unemployed, the government, the economy, society. That produces a full answer almost automatically.

Use the phrase labour force whenever you write the formula.

Building an answer

4 marks, "Explain two causes of unemployment."

Cyclical unemployment arises when total demand in the economy falls during a recession: firms sell less, produce less and therefore need fewer workers.
Structural unemployment arises when the pattern of demand changes permanently, an industry declines and its workers' skills no longer match the jobs available, so they remain unemployed even when the economy recovers.

6 marks, "Analyse the consequences of high unemployment for an economy."

Output is lost permanently: the economy operates inside its production possibility curve, and the goods not produced this year cannot be recovered.
Government finances worsen from both sides, less income tax and VAT collected, more spent on benefits, so the budget deficit grows.
The unemployed lose income and, over time, skills, which makes re-employment harder and can turn short-term joblessness into long-term exclusion.
There are social costs too: unemployment is associated with poorer health outcomes and higher crime, and these persist after the economic cycle turns.

The types, and what each needs

TypeCauseWhat actually helps
CyclicalFall in total demand during recessionExpansionary fiscal or monetary policy
StructuralLong-term change in industry and skillsRetraining, relocation support
FrictionalNormal time between jobsBetter job information; some is unavoidable
SeasonalDemand varies through the yearDiversification of local employment
TechnologicalAutomation replacing labourRetraining into growing sectors
VoluntaryChoosing not to work at the going wageAdjusting incentives: but not always a problem

Matching the policy to the type is where the marks are. Expansionary demand policy does nothing for structural unemployment, because the jobs and the skills are in different places.

A real case to quote

UK coal mining communities after the 1980s. Pit closures created structural unemployment that persisted for decades, because the skills were specific, the jobs were concentrated in particular towns, and workers could not easily move. It is the standard example for why structural unemployment is the hardest type to cure and why demand-side policy alone would not have touched it.
