Detailed notes on Government and the macroeconomy for Cambridge IGCSE Economics, covering key concepts, explanations, examples, and exam-focused revision points.
Employment and Unemployment Study Notes — Cambridge IGCSE Economics 0455 (2026 syllabus)
Types of unemployment, the unemployment rate, the costs of unemployment, and policies to reduce each type. Different types need different policies.
At a glance
Unemployment rate = (unemployed / labour force) × 100.
Cyclical: caused by recession (low AD).
Structural: skills mismatch.
Frictional: between jobs (short-term).
Seasonal: seasonal demand patterns.
Costs: lost output, gov finances, social effects.
Different types need different policies.
What you’ll learn
Mapped to the Cambridge IGCSE 0455 syllabus (2026).
4.5.1 — Define unemployment and the labour force.
4.5.2 — Calculate the unemployment rate.
4.5.3 — Distinguish between types of unemployment.
4.5.4 — Identify costs of unemployment to individuals, government, and economy.
4.5.5 — Identify policies to reduce each type.
Defining and measuring unemployment
Specific definition. Specific calculation.
Unemployment is when people who are willing and able to work, and actively seeking a job, cannot find one.
Three conditions:
Of working age (typically 16-65).
Want a job.
Actively looking.
Excluded: retirees, full-time students, disabled non-workers, parents at home (if not seeking work).
The labour force = all people in (1)+(2)+(3) PLUS those who already have jobs.
Cure. Demand-side policies — fiscal stimulus, lower interest rates, government spending. Stimulate AD → firms hire again.
2. Structural unemployment.
Cause. Skills mismatch — long-term changes in industry mean workers' skills don't match available jobs.
Example. Decline of UK coal mining (1980s-1990s); decline of US manufacturing as Asia gained comparative advantage.
Cure. Supply-side policies — retraining programmes, education, helping workers move to where jobs are.
3. Frictional unemployment.
Cause. Workers moving between jobs — searching, applying, retraining for a better fit. Always present in any economy.
Example. A graduate looking for their first job; a worker who left one job and is looking for another.
Cure. Mostly inevitable. Improve information (job search platforms, employment agencies) to shorten the search.
4. Seasonal unemployment.
Cause. Demand for the worker's services varies with the season.
Example. Agricultural workers in winter; ski instructors in summer; tourism workers in off-season.
Cure. Counter-seasonal industries; encourage workers to develop multiple skills.
Each type of unemployment has a distinct cause, so policymakers must match the cure (stimulus, retraining, information, or multi-skilling) to the cause.
Cambridge tip. Mark schemes for "types of unemployment" expect 4 distinct types with both causes AND cures. Top-band candidates name examples.
Cyclical: recession → demand-side cure.
Structural: skills mismatch → retraining cure.
Frictional: between jobs → information cure.
Seasonal: seasonal demand → multi-skilling cure.
Costs of unemployment
Individual, government, economy. All harmed.
To individuals:
Loss of income, savings drained.
Loss of skills (skills depreciate without practice).
Mental health impact (depression, anxiety).
Loss of social status.
Family stress.
To government:
Higher spending on unemployment benefits.
Lower tax revenue (no income tax from unemployed).
More healthcare costs (unemployment-related illness).
Higher crime-related spending.
To economy:
Lost output (real GDP below potential).
Lower aggregate demand (unemployed have less to spend).
Less innovation (skills not used).
Long-term unemployment is particularly damaging. Workers who are unemployed for over a year:
Lose much of their skills.
Find re-employment harder.
May leave the labour force entirely (no longer counted as unemployed).
Cambridge tip. Mark schemes for "costs of unemployment" expect costs at MULTIPLE LEVELS — individual, government, economy. Top-band answers cover all three.
Unemployment = working age + willing + actively seeking.
Rate = unemployed / labour force × 100.
Four types: cyclical, structural, frictional, seasonal.
Each type has different cure.
Costs: individual + government + economy.
Memorise this
Verbatim phrases and definitions Cambridge mark schemes credit.
Unemployment rate = unemployed / labour force × 100.
Cyclical ↔ demand-side stimulus.
Structural ↔ retraining / supply-side.
Frictional ↔ information / matching.
Costs: at individual, government, and economy levels.
How it’s examined
Unemployment appears on Paper 1 (calculation, types) and Paper 2 (8-10 marks evaluating policy responses). Examiner reports flag confusion between cyclical and structural as the most common error.

1Types of unemployment (8 marks)
Extended• Adapted from 0455/22 May/Jun 2024 Q21• unemployment
▼
Question
Identify and explain FOUR types of unemployment. (8 marks)
Step-by-step solution
Step 1
1. Cyclical / demand-deficient (2 marks). Caused by a recession — low aggregate demand → firms produce less → workers laid off. Example: 2008 financial crisis.
Step 2
2. Structural (2 marks). Skills mismatch between unemployed workers and available jobs. Caused by long-term changes in industries — e.g., decline of coal mining, growth of digital industries. Workers' skills don't match new jobs.
Step 3
3. Frictional (2 marks). Short-term unemployment when workers move between jobs — searching, applying, retraining. Always present in any economy.
Step 4
4. Seasonal (2 marks). Caused by seasonal patterns of demand — e.g., agricultural workers in winter, ski instructors in summer.
Answer
Four types: cyclical (recession), structural (skills mismatch), frictional (between jobs), seasonal (seasonal demand). Each requires different policy responses.
2Calculate unemployment rate (3 marks)
Core• unemployment

Question
An economy has 25 million people in the labour force. 1.5 million are unemployed. Calculate the unemployment rate. (3 marks)
Step-by-step solution
Step 1
Formula (1 mark). Unemployment rate = (unemployed / labour force) × 100.
Step 2
Substitute (1 mark). = (1.5 / 25) × 100.
Step 3
Calculate (1 mark). = 6%.
Answer
Unemployment rate = 6%.
3Costs of unemployment (6 marks)
Extended• unemployment
▼
Question
Explain THREE costs of high unemployment to an economy. (6 marks)
Step-by-step solution
Step 1
1. Lost output (2 marks). Unemployed workers produce nothing. Real GDP is below potential.
Step 2
2. Government finances (2 marks). Higher unemployment benefits paid AND lower tax revenue (no income tax from unemployed). Budget deficit widens.
Step 3
3. Social costs (2 marks). Long-term unemployment associated with poverty, mental health problems, family breakdown, crime, and social exclusion.
Answer
Three costs: (1) lost output (GDP below potential), (2) higher benefits + lower tax revenue, (3) social costs (poverty, mental health, family breakdown).

Key Definitions and Keywords — Employment and Unemployment
Definitions to memorise and the exact keywords mark schemes credit for employment and unemployment answers — sharpened from recent examiner reports for the 2026 0455 sitting.
Unemployment

Cyclical / demand-deficient unemployment
Examiner keyword
Unemployment caused by low aggregate demand, typically in a recession.
Structural unemployment
Examiner keyword
Unemployment caused by skills mismatch — workers' skills don't match available jobs.
Frictional unemployment
Examiner keyword
Short-term unemployment as workers move between jobs.
Seasonal unemployment
Unemployment caused by seasonal patterns of demand — agriculture, tourism, ski industry.
Common Mistakes and Misconceptions — Employment and Unemployment
The traps other students keep falling into on employment and unemployment questions — taken from recent Cambridge IGCSE 0455 examiner reports and mark schemes — and how to avoid them.
✕Counting all non-workers as unemployed
0455 Examiner Reports 2022-2024
▼
Why it happens
Loose usage.
How to avoid it
Unemployment requires (1) being of working age, (2) wanting a job, (3) actively seeking. Retirees, students, parents at home are NOT unemployed if not seeking work.
✕Confusing structural with cyclical unemployment
▼
Why it happens
Both involve workers without jobs.
How to avoid it
Cyclical = caused by a RECESSION (low AD) — temporary. Structural = caused by a long-term CHANGE in the industry (skills mismatch) — persistent.
✕Listing types of unemployment without policy implications
▼
Why it happens
Treating the question as descriptive.
How to avoid it
Each type needs a different policy: cyclical → demand-side stimulus; structural → retraining; frictional → information matching; seasonal → counter-cyclical jobs.
