A-LEVEL ECONOMICS NOTES: UNEMPLOYMENT (H1/H2)
1️⃣ What Is Unemployment?
Unemployment occurs when individuals who are willing and able to work, and actively seeking employment at the prevailing wage rate, are unable to find jobs.
Unemployment Rate:
\[ \frac{\text{Number of Unemployed}}{\text{Labour Force}}\times100\% \]
The labour force comprises employed and unemployed individuals.
2️⃣ Types of Unemployment
A. Demand-Deficient (Cyclical) Unemployment 📉
Occurs when aggregate demand (AD) falls, resulting in a decline in real national output.
- Firms experience falling sales and profits.
- Firms reduce production and demand fewer workers.
- Workers are retrenched, increasing unemployment.
Example: During a global recession, Singapore’s export-oriented industries may experience falling demand and retrench workers.
B. Structural Unemployment 🏭
Occurs when there is a mismatch between workers’ skills and the skills required by employers due to structural changes in the economy.
- Technological advancements make certain jobs obsolete.
- Workers lack the skills required in expanding industries.
- Occupational or geographical immobility makes it difficult for workers to find alternative employment.
Example: Automation and artificial intelligence may reduce demand for workers performing routine administrative tasks.
C. Frictional Unemployment 🔍
Occurs when workers are temporarily unemployed while searching for suitable jobs or transitioning between jobs.
Example: A fresh university graduate searching for their first job.
D. Seasonal Unemployment
Occurs when demand for labour fluctuates according to seasonal patterns.
Example: Workers employed in seasonal tourism activities.
3️⃣ Consequences of Unemployment
For Individuals:
- Loss of income and purchasing power.
- Lower material standard of living.
- Psychological stress and deterioration in well-being.
For the Economy:
- Actual output falls below potential output during demand-deficient unemployment, resulting in a negative output gap.
- Government receives less personal income tax revenue.
- Government may incur higher expenditure on unemployment-related assistance.
- Prolonged unemployment may cause workers’ skills to deteriorate, reducing future productive capacity.
4️⃣ Policies to Reduce Unemployment
A. Expansionary Fiscal Policy
Government increases expenditure or reduces taxes.
➡️ AD increases.
➡️ Firms increase production.
➡️ Derived demand for labour increases.
➡️ Demand-deficient unemployment falls.
B. Supply-Side Policies
Government provides education, training and skills upgrading.
➡️ Workers acquire skills demanded by employers.
➡️ Occupational immobility decreases.
➡️ Structural unemployment falls.
🇸🇬 Singapore Example: SkillsFuture supports lifelong learning and workforce reskilling.
C. Job-Matching Programmes
Improve the flow of information between jobseekers and employers, reducing frictional unemployment.
🇸🇬 Singapore Example: Workforce Singapore’s career matching and employment facilitation services.
5️⃣ Evaluation: Which Policy Is More Effective?
The effectiveness of a policy depends on the underlying cause of unemployment.
- Expansionary demand-management policies are more appropriate for demand-deficient unemployment but may create inflationary pressures.
- Supply-side policies address structural unemployment more directly but require time to produce results.
- Job-matching programmes reduce information gaps but cannot eliminate a fundamental skills mismatch.
⭐ A-Level Examination Tip:
Always establish the correct economic transmission mechanism:
Fall in AD → Fall in Real Output → Fall in Derived Demand for Labour → Rise in Demand-Deficient Unemployment.
For evaluation, explain why different types of unemployment require different policy responses.
