Cambridge O Level Economics: Employment and unemployment (2281) – Revision Notes

These notes condense section 4.7 of the Cambridge O Level Economics (2281) syllabus for examination in 2026, version 2. The study guide has the full explanations and longer examples, so read that first, and use the practice questions. Other links: the Cambridge O Level Economics hub, the printable checklist and the free diagnostics. All countries and figures here are made up.

4.7.1 Definitions

Term	Meaning
Employment	Paid work, for an employer or self-employed
Unemployment	Without a job, willing and able to work, and looking for one
Labour force	Employed + unemployed
Full employment	All who want a job at the prevailing wage and are capable of doing one can get it; a small amount of frictional unemployment still exists

Outside the labour force: full-time students, the retired, and anyone not looking for work.

4.7.2 Changing patterns of employment

Trend	Reasons to give
Bigger tertiary share	Rising incomes raise demand for services; farm and factory machinery needs fewer workers; firms buy more services
Bigger formal economy	Larger registered firms replace small unrecorded traders; more education; stricter registration and tax collection
Rising female participation	Attitudes shift; girls stay longer in school; equal-treatment laws; households that need two wages
Lower state share	A turn to markets: privatisation, closing state firms, private firms taking over supply

The level of employment rises with growth in output and falls in a recession.

Small reminder: a country has 2,400,000 employed and tertiary workers are 52% of employment. Tertiary workers = 0.52 × 2,400,000 = 1,248,000.

Women’s share: a labour force of 800,000 includes 320,000 women, a share of 320,000 ÷ 800,000 × 100 = 40%. Later the labour force is 900,000 with 405,000 women, a share of 45%. Women’s numbers rose by 85,000, while the total labour force rose by 100,000, so the share rose by 5 percentage points.

4.7.3 Measuring unemployment

Rate (%) = unemployed ÷ labour force × 100

Working order:

1. Work out the labour force by adding the employed and the unemployed.
2. Put the jobless figure over that total.
3. Convert to a percentage and write the % sign.

Reminder: 846,000 employed, 54,000 unemployed. Labour force = 900,000. Rate = 54,000 ÷ 900,000 × 100 = 6.0%.

Working backwards: unemployment 96,000 is 6% of the labour force. Labour force = 96,000 ÷ 0.06 = 1,600,000, so employed = 1,504,000.

	Claimant count	Labour force survey
Who	People claiming benefit	People in a sample who say they are jobless and looking
Strength	Quick, cheap, existing records	Includes non-claimants; same definition across countries
Weakness	Misses non-claimants; may include people who work while claiming	Costly; sampling error; relies on honest answers

Reminder: claimant count 90,000. Survey rate 8% of a labour force of 1,250,000 gives 0.08 × 1,250,000 = 100,000. The survey is 10,000 higher.

4.7.4 Types of unemployment

Type	Cause	Example	Remedy type
Frictional	Search and matching time between jobs	A worker leaves one firm and spends weeks applying	Better job information
Structural	Industry declines; skills or location mismatch	Handloom weavers when a mill automates	Training, relocation help
Cyclical	Fall in total demand	Lay-offs in a recession	Higher demand

Cyclical chain: spending falls, sales fall, output falls, labour demand falls, jobs are cut.

Reminder: labour force 1,000,000; frictional 20,000, structural 45,000, cyclical 35,000. Total unemployed = 100,000, so the rate is 100,000 ÷ 1,000,000 × 100 = 10.0%. Without the cyclical part, 65,000 ÷ 1,000,000 × 100 = 6.5%. Cyclical share = 35,000 ÷ 100,000 × 100 = 35%.

Diagram in words: draw a production possibility curve. A recession with high cyclical unemployment puts the economy at a point inside the curve, because labour is idle. Recovery moves the point out towards the curve. Only growth in resources or technology shifts the curve itself.

4.7.5 Consequences

For	Main points
Individual	Lower income; stress; skills fade; possible time to retrain
Firms	Lower sales and profit; pool of labour for hiring; lost trained staff
Economy	Wasted capacity (a point inside the production possibility curve); smaller tax receipts; more benefit spending; inequality; social problems

Reminder: 20,000 more people unemployed, each costing 4,000 in lost tax and benefit and 12,000 in lost output. Fiscal cost = 20,000 × 4,000 = 80,000,000. Output lost = 20,000 × 12,000 = 240,000,000.

4.7.6 Policies

Type of unemployment	Policy	Effectiveness depends on
Cyclical	Fiscal and monetary policy to raise demand	Confidence, time lags, spare capacity, borrowing
Structural	Education, training, relocation help, subsidies, incentives to locate in depressed areas	Years to work; willingness to retrain or move; cost
Frictional	Job centres, online vacancy information	Cannot remove all search time

Cost per job reminder: 12,000,000 spent on a scheme that finds 2,400 jobs costs 12,000,000 ÷ 2,400 = 5,000 per job.

Evaluation prompts

• It depends on the type of unemployment, so one policy rarely fits all.
• In the short run a demand boost helps; in the long run skills and mobility matter more.
• A policy is judged by size of effect, speed, cost and who pays.
• A rich country and a poor country may face different mixes of types.

Model paragraphs to adapt

Fiscal policy, cyclical unemployment: A government can raise spending on roads. This gives builders work and raises their incomes, so they spend more in shops, and shops hire more staff. Unemployment falls if the problem is a lack of demand. However, the effect may come slowly, it raises borrowing, and it does little if the unemployed lack the skills the new jobs need.

Training, structural unemployment: A free course in machine repair gives former mill workers skills that firms are seeking. It reduces occupational immobility, so vacancies are filled. It works only if firms are hiring in that field, and the benefits arrive after months or years.

Consequence for a firm: When many households lose their jobs, they cut spending, so a clothing shop sells less. Falling revenue reduces profit and may force the owner to cut hours or close.

Evaluating in four moves

1. Name the type of unemployment.
2. Pair it with a matching policy and explain the chain.
3. Weigh speed, size, cost and side effects.
4. Reach a judgement that depends on the type, the country and the time frame.

Must-know distinctions

• Unemployment rate versus number unemployed. The number can rise while the rate falls if the labour force grows faster.
• Claimant count versus survey. One counts benefit claimants, the other counts reported job-seeking.
• Frictional versus structural. Frictional is short search time with suitable jobs available; structural is a mismatch that can last years.
• Structural versus cyclical. Structural is a change in what the economy needs; cyclical is a shortage of demand.
• Employment versus labour force. Labour force includes the unemployed.

Quick self-test

1. Write the formula used to find the unemployment rate.
2. A country has 2,850,000 employed and 150,000 unemployed. Calculate the rate.
3. Why can full employment still include some unemployment?
4. Give two reasons for a larger tertiary share of employment.
5. Give one disadvantage of the claimant count.
6. Employment rises by 30,000 and the labour force by 50,000. What happens to unemployment?
7. Which type of unemployment follows a recession?
8. Name one policy for structural unemployment and one limit.
9. A scheme costs 9,000,000 and creates 1,500 jobs. Calculate the cost per job.
10. Name one consequence of unemployment for firms.

Answers

1. Unemployed ÷ labour force × 100.
2. Labour force = 3,000,000. Rate = 150,000 ÷ 3,000,000 × 100 = 5.0%.
3. Some people are always between jobs (frictional), so the labour market never matches perfectly.
4. Higher incomes raise spending on services; machines reduce the farm workforce.
5. It misses people who are unemployed but not claiming.
6. Unemployment rises by 20,000, since 50,000 − 30,000 = 20,000.
7. Cyclical.
8. Retraining; it takes years and trainees must be willing and able.
9. 9,000,000 ÷ 1,500 = 6,000.
10. Households spend less, so sales and profit fall.

Where marks are usually lost

• Dividing by employment instead of the labour force.
• Defining unemployment without “willing and able” and “looking for work”.
• Describing the three types without a cause for each.
• Offering a demand boost for a structural problem.
• Stating consequences for “society” but not for the individual or firms separately.
• Listing policies with no explanation of how they work.
• Never judging effectiveness: no mention of time lags, cost or size.
• Missing units, such as the percentage sign.
