4.5 Unemployment

1. Meaning of Unemployment (AO1)

Definition

  • Unemployment: When people who are willing and able to work at the current wage rate cannot find a job

Key idea (AO2)

  • Only includes people in the labour force (not students, retirees, etc.)
  • Usually expressed as an unemployment rate (%)

2. Measures of Unemployment (AO1 + AO2)

Main measures

  • Unemployment rate:
    (Number of unemployed ÷ labour force) × 100
  • Claimant count:
    Number of people claiming unemployment-related benefits

Difficulties in measurement (important)

  • Hidden unemployment: People not actively seeking work are not counted
  • Underemployment: People working part-time but want full-time jobs
  • Informal economy: Some unemployed people may be working unofficially
  • Differences in definitions: Countries measure unemployment differently
  • Time lag: Data may not reflect current situation

Key insight

  • Official figures may underestimate true unemployment

3. Causes and Types of Unemployment (AO2)

A. Frictional Unemployment

  • Short-term unemployment when people are between jobs

Causes

  • Time taken to search for jobs
  • Imperfect information

Key point

  • Often unavoidable and not a major problem

B. Structural Unemployment

  • Mismatch between workers’ skills and job requirements

Causes

  • Decline of industries
  • Changes in demand
  • Lack of skills or mobility

Example chain
Industry declines → workers lose jobs → skills no longer needed → unemployment persists

C. Cyclical (Demand-deficient) Unemployment

  • Caused by fall in aggregate demand

Causes

  • Economic recession
  • Reduced consumer spending

Chain
AD falls → firms reduce output → workers laid off → unemployment rises

D. Seasonal Unemployment

  • Occurs due to seasonal patterns in industries

Examples

  • Tourism
  • Agriculture

E. Technological Unemployment

  • Caused by automation and machinery replacing labour

Key idea

  • Workers may lose jobs unless they retrain

4. Consequences of Unemployment (AO2 + AO3)

Economic effects

  • Loss of output: Economy produces below potential
  • Lower tax revenue: Less income tax collected
  • Higher government spending: More benefits paid

Social effects

  • Poverty: Loss of income
  • Lower living standards
  • Health issues: Stress, mental health problems
  • Crime: May increase in some cases

Key insight

  • Unemployment creates both economic inefficiency and social costs

5. Evaluation (AO3)

  • Type of unemployment matters:
    • Frictional is less serious than structural or cyclical
  • Duration matters:
    • Long-term unemployment is more damaging
  • Economic context:
    • In a recession, unemployment is harder to reduce
  • Government response:
    • Policies like training or demand stimulation can reduce unemployment
  • Trade-offs:
    • Reducing unemployment may increase inflation

Final Insight

  • Unemployment occurs when labour supply exceeds labour demand
  • It can be short-term or long-term, and caused by different factors
  • It has serious economic and social consequences
  • Its impact depends on type, duration, and policy response
