Cambridge O Level Economics: Employment and unemployment (2281)

This guide covers section 4.7 of the Cambridge O Level Economics (2281) syllabus for examination in 2026, version 2. It defines the key terms, shows why jobs shift between sectors and groups, sets out the two ways of measuring joblessness, separates the three causes, weighs the damage done and compares the remedies. There are no tiers, so all of it is for everyone. Every country, firm and number below is invented and illustrative, so none of it is real data.

4.7.3	Compare the claimant count with the labour force survey and apply the unemployment rate formula
4.7.4	Tell apart frictional, structural and cyclical unemployment
4.7.5	Work out the effects on a jobless person, on businesses and on the national economy
4.7.6	Set out a range of remedies and judge how well each might work

4.7.1 Definitions

• Employment: having paid work, whether you are hired by a firm or run your own business.
• Unemployment: being without a job while able and willing to take one and searching for it.
• Labour force: the employed plus the unemployed.
• Full employment: everyone who is willing and able to work at the going wage has a job. Even so, a few people will be unemployed at any moment while they change jobs.

Full-time students, retired people and anyone who has chosen not to seek work sit outside the labour force, so none of them is counted as unemployed.

4.7.2 Changing patterns and level of employment

The pattern of employment is who works, in which sector and under which employer. The level is how many people work. Both change over time.

Illustrative Country Y has 6,000,000 workers in both years.

Share of employment	Year 1	Year 10
Primary	45%	18%
Secondary	30%	30%
Tertiary	25%	52%

Tertiary workers rise from 0.25 × 6,000,000 = 1,500,000 to 0.52 × 6,000,000 = 3,120,000, an increase of 1,620,000.

Why the tertiary and formal shares rise as an economy develops

1. Higher incomes lead households to spend a larger share on services such as tourism, banking and education.
2. Machines raise output per farm worker, so fewer people are needed in the primary sector.
3. Firms buy more transport, finance and communication services.
4. Larger registered firms replace small unrecorded traders. Workers move into the formal economy, where jobs carry contracts and taxes are recorded.

Why more women join the labour force. Attitudes change, so paid work outside the home is more accepted. More girls finish school, laws can ban discrimination, smaller families free up time and many households want a second income. In Country Y the labour force is 3,000,000 with 1,260,000 women in year 1 (1,260,000 ÷ 3,000,000 × 100 = 42%). By year 10 it is 3,300,000 with 1,650,000 women (50%).

Falling state employment. A country shifting towards a market economy sells or closes state-owned firms and lets private firms supply more. In Country Y the public sector employs 480,000 of 2,400,000 formal workers (20%) before reform and 300,000 of 2,500,000 (12%) after.

4.7.3 Measurement of unemployment

Unemployment rate (%) = number unemployed ÷ labour force × 100, where labour force = employed + unemployed.

Worked example. Country X: year 1 has 3,725,000 employed and 275,000 unemployed. Year 2 has 3,790,000 employed and 310,000 unemployed.

Year 1: labour force = 3,725,000 + 275,000 = 4,000,000
        rate = 275,000 / 4,000,000 x 100 = 6.875%, so 6.9%
Year 2: labour force = 3,790,000 + 310,000 = 4,100,000
        rate = 310,000 / 4,100,000 x 100 = 7.56%, so 7.6%

Employment rose by 65,000, yet the rate rose, because the labour force grew by 100,000. The newcomers to the labour force outnumbered the new jobs.

Two ways to measure

	Claimant count	Labour force survey
Counts	People registered for unemployment benefit	People in a sampled group who say they are jobless and searching
For	Cheap and quick; uses records the government already holds	Includes people who do not claim; uses one definition, so countries can be compared
Against	Misses unemployed people who are not entitled to benefit or do not claim; may include people who claim while working	Costs more; depends on sample size and honest answers

Worked example. Country X has a claimant count of 150,000 and a labour force of 4,100,000. A survey of 2,500 people in the labour force finds 140 unemployed.

Survey rate = 140 / 2,500 x 100 = 5.6%
Scaled up   = 0.056 x 4,100,000 = 229,600
Claimant rate = 150,000 / 4,100,000 x 100 = 3.66%, so 3.7%
Gap = 229,600 - 150,000 = 79,600

The survey suggests about 79,600 people want work but are not on the benefit register. Survey figures are estimates from a sample, so they carry some error.

4.7.4 Causes and types of unemployment

Kind	Why it arises	Illustration
Frictional	Time taken to search and match when moving between jobs; imperfect information about vacancies	A graduate looking for a first post
Structural	An industry declines or changes, so workers’ skills or locations do not match the vacancies (occupational and geographical immobility)	A shipyard closes after buyers move to another country; its welders lack the skills for new roles
Cyclical	Total demand falls in a downturn, so firms cut output and jobs	A builder lays off crews when households stop buying homes

Chain for cyclical unemployment: spending by consumers and investors drops, stocks pile up, firms cut production, and labour is let go. It is also called demand-deficient unemployment.

Worked example. Country Z has a labour force of 6,000,000. Unemployment is 420,000: frictional 60,000, structural 190,000, cyclical 170,000.

Rate = 420,000 / 6,000,000 x 100 = 7.0%
Cyclical share = 170,000 / 420,000 x 100 = 40.5%
If recovery removes all cyclical unemployment:
  unemployed = 60,000 + 190,000 = 250,000
  rate = 250,000 / 6,000,000 x 100 = 4.2%

A recovery cannot get below 4.2% here. The remaining unemployment needs different remedies.

4.7.5 Consequences of unemployment

Who is affected	Harm done	Possible upside
The individual	Less income and a lower standard of living; anxiety and weaker health; skills and morale erode as the spell lengthens	A chance to retrain or hunt for a better fit
Firms	Households spend less, so sales and profit fall; trained staff may leave for good	A larger pool of labour makes hiring easier and may slow wage rises
The economy	Wasted capacity, so output sits inside the production possibility curve; the government collects less tax and pays out more benefit; a wider gap between rich and poor; social strain	Less pressure on wages may ease inflation

Worked example. In Country Z, unemployment rises by 80,000. Each unemployed person pays 1,500 less tax a year, receives 2,700 in benefit and would have produced 14,000 of output (invented currency units).

Fiscal cost = 80,000 x (1,500 + 2,700) = 336,000,000
Output lost = 80,000 x 14,000 = 1,120,000,000

The government loses 336 million from its budget. The economy loses 1,120 million of goods and services, the opportunity cost of idle labour.

4.7.6 Policies to reduce unemployment

Pair each remedy with the cause it fits, then judge how well it works.

Policy	Targets	How it works	Limits
Fiscal: more government spending or lower taxes	Cyclical	Raises total demand, so firms hire	Raises government borrowing; slow to take effect; may push up prices if the economy is near full capacity
Monetary: lower interest rates	Cyclical	Cheaper borrowing raises spending and investment	Households and firms may not borrow if confidence is low
Education and training	Structural	Gives workers skills that match vacancies	Takes years; trainees must be willing and able
Better job information and job centres	Frictional	Matches workers to vacancies faster	Cannot remove all search time
Help to move (relocation grants, cheaper housing)	Structural (geographical)	Cuts geographical immobility	Costly; families may not want to move
Subsidies for firms that hire	Structural, long-term	Lowers the cost of employing a worker	Costs taxpayers; firms may hire people they would have hired anyway
Incentives for new businesses to locate in high-unemployment areas	Structural	Creates jobs where they are needed	Firms may still choose better-connected areas

Worked example: cost per job. Country Z compares two schemes.

Training: 18,000,000 for 6,000 trainees; 55% find work
  jobs = 0.55 x 6,000 = 3,300
  cost per job = 18,000,000 / 3,300 = 5,455 (nearest whole number)
Public works: 40,000,000 for 5,000 temporary jobs
  cost per job = 40,000,000 / 5,000 = 8,000

Training is cheaper per job and the jobs are lasting. Public works help immediately but the jobs may end. If the 3,300 trainees were all unemployed, the rate would move from 7.0% to (420,000 − 3,300) ÷ 6,000,000 × 100 = 6.9%. The effect on the total is small, so judge scale and time as well as cost.

Evaluating a policy

1. Which type of unemployment is the problem? Cyclical needs demand; structural needs skills or mobility; frictional needs information.
2. How fast does it work, and how large is the effect compared with the problem?
3. What does it cost, and who pays?
4. What side effects arise, such as higher prices or more borrowing?
5. Judge: a country with mainly structural unemployment gains little from a demand boost.

Common errors

• Treating students, pensioners and full-time carers as part of the jobless total.
• Claiming that full employment leaves no one without a job.
• Dividing unemployed by employed instead of by the labour force.
• Saying a rise in employment must lower the unemployment rate.
• Offering a demand-side remedy for structural unemployment, or retraining for cyclical unemployment.
• Listing consequences without saying who bears them.
