Welcome to AS 2 Economics: Mastering Unemployment!
Welcome to your study notes for Unemployment, one of the most vital chapters in AS 2: Managing the National Economy. Whether you find macroeconomic diagrams a breeze or feel a little overwhelmed by economic data, do not worry! We will break down every concept step-by-step using clear language, everyday examples, and handy memory tricks.
Reducing unemployment is one of the government's primary macroeconomic objectives. Understanding why people lose jobs, how we measure joblessness, and what governments can do about it is essential for scoring top marks in your CCEA A Level exams.
1. What is Unemployment?
In everyday speech, people often say someone is "unemployed" if they do not have a job. But in economics, the definition is much more specific!
The Official Definition
Unemployment occurs when individuals who are able, available, and actively seeking work at the current market wage rate cannot find a job.
To understand this properly, we divide the working-age population into two key groups:
1. The Economically Active (The Labour Force): People who are either currently employed or actively seeking work and available to start.
2. The Economically Inactive: People of working age who are not in work and are not actively looking for work. Examples include full-time university students, stay-at-home parents, people with long-term sickness, and early retirees.
Calculating the Unemployment Rate
To calculate the headline unemployment rate as a percentage, we use the following formula:
\(\text{Unemployment Rate (\%)} = \left( \frac{\text{Number of Unemployed People}}{\text{Total Labour Force}} \right) \times 100\)
Note: Always remember that the denominator is the Labour Force (employed + unemployed), NOT the entire population of the country!
Common Mistake to Avoid
Mistake: Thinking a retired person or a school pupil is "unemployed".
Correction: They are economically inactive because they are not actively looking for paid work.
Key Takeaway: You are only officially unemployed if you want a job, are ready to work, are actively looking, but cannot find one.
2. Measuring Unemployment: LFS vs Claimant Count
In the UK, the government measures unemployment using two different methods. Exam questions frequently ask you to compare them!
Method 1: The Labour Force Survey (LFS) / ILO Measure
The Labour Force Survey (LFS) is conducted by the Office for National Statistics (ONS) using the internationally agreed International Labour Organisation (ILO) guidelines.
How it works: It is a large sample survey of around 40,000 households every quarter. To be counted as unemployed under the LFS, a person must:
• Have been without a paid job during the reference week.
• Be available to start work within the next two weeks.
• Have actively looked for work in the past four weeks (or be waiting to start a job already obtained).
Advantages:
• International Comparability: Because it uses standard ILO rules, UK unemployment figures can be directly compared with countries like France, Germany, or the USA.
• Comprehensive: Captures people looking for work who might not be eligible for government benefits (e.g., individuals with high savings or a working partner).
Disadvantages:
• Sampling Errors: Because it is a survey of a sample of the population, it is subject to statistical margin of error.
• Time Lag & Cost: Collecting and processing survey data takes time and is expensive.
Method 2: The Claimant Count
The Claimant Count simply records the number of people who are claiming unemployment-related benefits, mainly Jobseeker's Allowance (JSA) and certain elements of Universal Credit.
Advantages:
• Fast & Cheap: The data is collected automatically from administrative records, so it is published quickly every month with minimal cost.
• Exact Figure: It is a complete count of actual claimants, not a sample estimate.
Disadvantages:
• Excludes many jobseekers: People who are actively looking for work but ineligible for benefits (due to a partner's income or personal savings) are not counted.
• Benefit Fraud: Some people may claim benefits while working illegally in the shadow economy.
• Policy Changes: Changes to benefit eligibility rules by the government can artificially raise or lower the claimant count overnight without any real change in true joblessness.
Quick Comparison: LFS vs Claimant Count
Did you know? The LFS figure is almost always higher than the Claimant Count in the UK. This is because many jobseekers (such as students looking for graduate roles or second earners in households) are looking for work but cannot claim welfare benefits.
Key Takeaway: LFS uses a representative survey following global ILO criteria, making it ideal for international comparisons. The Claimant Count records administrative welfare claims, making it cheap and fast but prone to policy distortion.
3. Types and Causes of Unemployment
To fix unemployment, an economist must first diagnose its cause. We classify unemployment into five main types. A helpful mnemonic to remember them is SCARF: Structural, Cyclical, Actual real-wage (Real-wage), Regional/Seasonal, and Frictional.
1. Frictional Unemployment
What it is: Short-term unemployment that occurs when people are "between jobs".
Why it happens: Searching for the right job takes time. For example, recent university graduates looking for their first graduate position, or workers who voluntarily resigned to seek better career opportunities.
Is it dangerous? Generally no. In a healthy economy, a small amount of frictional unemployment is normal and even beneficial because it helps match workers to jobs where they are most productive.
2. Structural Unemployment
What it is: Long-term unemployment caused by a permanent decline in demand for a specific industry or a fundamental mismatch between workers' skills and the skills needed by employers.
Why it happens:
• Occupational Immobility: Workers lack the transferable skills required for new jobs (e.g., a former coal miner or factory worker struggling to find work in a digital software industry).
• Geographical Immobility: Jobs exist in one part of the country (e.g., London and the South East), but unemployed workers live elsewhere (e.g., former industrial towns in Northern England or parts of Northern Ireland) and cannot move due to high house prices, family ties, or regional living costs.
• Technological Change / Automation: Machines, software, and robotics replace human labour.
3. Cyclical (Demand-Deficient) Unemployment
What it is: Unemployment caused by a general lack of Aggregate Demand (\(AD\)) across the whole economy during a recession or economic slowdown.
How it works:
When consumer and business confidence falls, spending drops (\(AD\) shifts left). Because the demand for labour is a derived demand (firms only hire workers to make goods and services that consumers want to buy), firms cut output and lay off staff.
\(AD \downarrow \implies \text{Real GDP} \downarrow \implies \text{Demand for Labour} \downarrow \implies \text{Cyclical Unemployment} \uparrow\)
4. Seasonal Unemployment
What it is: Unemployment that recurs at predictable times of the year due to weather conditions or seasonal demand patterns.
Examples: Ski instructors in summer, fruit pickers in winter, or lifeguards and seaside hotel staff after the summer holiday season ends.
5. Real-Wage (Classical) Unemployment
What it is: Unemployment caused when real wages are kept artificially above the free market equilibrium wage level.
Why it happens: If powerful trade unions or a legal National Minimum Wage push wages above the equilibrium level where labour supply equals labour demand (\(W_1 > W_e\)), the supply of labour will exceed the demand for labour. Firms cannot afford to hire as many workers at the higher wage, creating a surplus of unemployed labour.
Key Takeaway: Cyclical unemployment is caused by a slump in overall economic demand (demand-side problem), whereas structural, frictional, and real-wage unemployment are caused by labour market rigidities (supply-side problems).
4. Full Employment and the Natural Rate of Unemployment (NRU)
Don't be fooled by the term Full Employment! It does not mean 100% of the labour force is working (\(0\%\) unemployment).
The Concept of Full Employment
Full employment is defined as the level of employment where all available labour resources are being used efficiently, and the only remaining unemployment is frictional and structural.
Even in a booming economy, there will always be workers transitioning between jobs or undergoing retraining.
The Natural Rate of Unemployment (NRU)
The Natural Rate of Unemployment is the rate of unemployment that exists when the aggregate labour market is in equilibrium and the economy is producing at its full-capacity potential output (on the Long-Run Aggregate Supply curve).
\(\text{Natural Rate of Unemployment} = \text{Frictional Unemployment} + \text{Structural Unemployment}\)
When an economy is operating at its natural rate, cyclical unemployment is zero.
Key Takeaway: Full employment does not equal zero unemployment. It means the elimination of cyclical (demand-deficient) unemployment.
5. Consequences and Costs of Unemployment
Unemployment creates significant economic and social costs across four main groups: individuals, businesses, the government, and the economy as a whole.
1. Consequences for the Individual
• Loss of Income: Reduced household disposable income leads to a lower standard of living and potential poverty or debt.
• Loss of Skills ("Hysteresis"): The longer a worker remains unemployed, the more their skills deteriorate and become outdated. This makes them less employable in the future.
• Social and Psychological Costs: Stress, loss of self-esteem, depression, and relationship breakdowns are strongly linked to long-term unemployment.
2. Consequences for Businesses
• Lower Sales and Revenue: With lower household incomes, consumer spending falls, especially for luxury and non-essential goods.
• Underutilised Capacity: Firms may operate with idle machines and empty premises.
• One potential benefit: A larger pool of unemployed workers may give firms greater choice when hiring and reduce wage-push pressure.
3. Consequences for the Government
• Deterioration of the Fiscal Balance:
- Tax revenues fall: Less income tax, less VAT (due to reduced consumer spending), and lower corporation tax from struggling firms.
- Government spending rises: Increased expenditure on welfare transfer payments (e.g., Universal Credit) and public healthcare services.
• Opportunity Cost: Money spent on unemployment benefits cannot be invested in schools, infrastructure, or hospitals.
4. Consequences for the Economy as a Whole
• Lost Output (GDP Gap): An economy with high unemployment is operating inside its Production Possibility Frontier (PPF). Scarce productive resources are left idle, resulting in a permanent loss of potential output.
• Social Costs: Increased crime rates, regional decay, and greater strain on social support services.
Key Takeaway: High unemployment causes a double blow to public finances (lower tax in, higher welfare out) and leaves an economy operating below its productive capacity.
6. Policies to Reduce Unemployment
The right policy depends entirely on the type of unemployment the government is trying to solve. Using the wrong tool for the wrong type of unemployment will not work!
1. Demand-Side Policies (To Cure Cyclical Unemployment)
When unemployment is caused by a recession or deficiency in aggregate demand, the government and central bank can use expansionary policies:
A. Expansionary Fiscal Policy:
• Lower income tax to increase consumer spending (\(C\)).
• Increase direct government spending (\(G\)) on public projects (e.g., building roads or hospitals).
• Result: Increases \(AD\) (\(AD = C + I + G + (X - M)\)), prompting firms to hire more staff to meet rising demand.
B. Expansionary Monetary Policy:
• Central bank cuts the base interest rate.
• Low interest rates make borrowing cheaper and saving less rewarding, boosting consumption (\(C\)) and capital investment (\(I\)).
2. Supply-Side Policies (To Cure Structural & Frictional Unemployment)
If unemployment is structural or frictional, boosting aggregate demand alone will only create inflation! Instead, the government must improve the functioning and flexibility of the labour market:
• Education and Retraining Schemes: Government-funded training programs to give workers relevant modern skills (tackling occupational immobility).
• Regional Policy & Relocation Subsidies: Grants and subsidies to encourage businesses to set up in high-unemployment areas, or affordable housing schemes to help workers move to where jobs are (tackling geographical immobility).
• Improving Job Information: Investing in online job search portals, careers advice, and Jobcentres to reduce the time jobseekers spend searching (reducing frictional unemployment).
• Welfare & Tax Reforms: Lowering basic income tax rates or tapering welfare benefits to improve financial incentives to take up employment.
Evaluation of Unemployment Policies
• Time Lags: Supply-side policies like education, apprenticeships, and infrastructure projects can take years to bear fruit.
• Cost: Both expansionary fiscal policy and supply-side retraining involve heavy government spending, worsening the national debt.
• Risk of Inflation: Excessive demand-side stimulus can cause demand-pull inflation if the economy approaches full capacity.
Key Takeaway: Match the policy to the cause: Use demand-side policies for cyclical unemployment, and supply-side policies for structural and frictional unemployment.
