Welcome to the Employment and Unemployment Chapter!
Hey Economists! This chapter is one of the most important parts of macroeconomics because unemployment isn't just a statistic; it affects real people's lives and determines a country's overall health.
We will learn how to define who is counted as unemployed, explore the different reasons why people lose jobs (it's not always the economy's fault!), and look at how governments try to get people back to work. Don't worry if some of the concepts seem tricky at first—we'll break down the jargon into simple steps!
Section 1: Defining and Measuring Unemployment (AS Level Core)
1.1 Defining the Labour Force and Unemployment
To understand unemployment, we first need to know who we are counting.
The Working Population (or Labour Force) includes everyone who is of working age (e.g., typically 16 to 65) who is either currently employed or is officially unemployed (actively seeking work).
It excludes children, retirees, full-time students, and those who choose not to work (e.g., stay-at-home parents).
Definition of Unemployment (4.5.1):
A person is defined as unemployed if they are of working age, currently without work, but are willing and able to work, and are actively seeking employment.
The Unemployment Rate:
This is the key statistic that governments aim to keep low. It is calculated as a percentage:
$$ \text{Unemployment Rate} = \frac{\text{Number of Unemployed People}}{\text{Labour Force}} \times 100 $$
1.2 Measures and Difficulties in Measurement (4.5.2)
Different countries use slightly different methods, leading to difficulties in comparing data internationally or even over time:
A. Common Measurement Methods:
- Claimant Count: Measures the number of people who are claiming unemployment benefits. This is often criticized for being too low, as not everyone qualifies or applies for benefits.
- Labour Force Survey (LFS) / Standard Definition: A survey of households based on the official definition (actively seeking work). This is usually considered a more accurate representation of true unemployment.
B. Difficulties in Measurement (The Hidden Problems):
The headline unemployment rate often hides bigger problems:
- Hidden Unemployment (Discouraged Workers): These are people who have given up actively looking for work because they believe there are no jobs available. Since they are no longer "actively seeking," they are not counted in the official labour force, making the unemployment rate artificially lower. (Imagine a student graduating and looking for 12 months, then giving up—they disappear from the statistic!)
- Underemployment: People who are working, but want to work more hours, or are employed in jobs that do not utilize their skills (e.g., a civil engineer working as a waiter). They are counted as employed, but the economy is not using its resources efficiently.
- Regional/Group Disparities: The national average hides the fact that certain regions or demographic groups (like young people or certain ethnicities) may have much higher rates of unemployment.
Section 2: Causes and Types of Unemployment (AS & A Level)
Unemployment is not caused by a single factor. Economists categorize the causes to help governments select the right policy response.
2.1 Traditional Types of Unemployment (AS Level)
These types are often related to the natural inefficiencies of the labour market or specific industries.
- Frictional Unemployment (4.5.3):
- Definition: Unemployment that occurs when people are temporarily between jobs. It is short-term and results from the time it takes for workers to search for new jobs that match their skills, or for firms to find new workers.
- Analogy: Changing trains. You know where you are going, but there is a waiting time between one train arriving and the next one leaving.
- Structural Unemployment (4.5.3):
- Definition: Long-term unemployment caused by a mismatch of skills or a permanent decline in a specific industry. It happens when the structure of the economy changes (e.g., due to globalisation or technological advancement).
- Example: A coal miner becomes unemployed because the coal industry closes down. Their skills (mining) are now obsolete in that location.
- This type is severe because the worker requires significant retraining or geographical relocation.
- Seasonal Unemployment (4.5.3):
- Definition: Unemployment that arises because demand for labour is dependent on the time of year.
- Example: Ski resort instructors in the summer, or agricultural workers outside of harvest time.
- Technological Unemployment (4.5.3):
- Definition: A specific type of structural unemployment where jobs are replaced by machines, automation, or Artificial Intelligence (AI).
- Did you know? The rise of automated supermarket checkouts is a real-world example of technological unemployment affecting cashier roles.
- Cyclical Unemployment (Demand-Deficient Unemployment) (4.5.3):
- Definition: Unemployment caused by a fall in Aggregate Demand (AD) during an economic recession or downturn. If firms sell less, they need fewer workers.
- This is the most worrying type for a government because it signals a deep economic malaise.
- Key feature: The economy is operating inside its Production Possibility Curve (PPC).
2.2 Equilibrium vs. Disequilibrium Unemployment (A Level Concept 9.3.2)
For A Level, we classify unemployment based on how it relates to the labour market's equilibrium wage rate (W*).
A. Equilibrium Unemployment (Voluntary Unemployment)
This occurs when the labour market is in equilibrium (where labour demand meets labour supply), but some people are still not working. This is considered voluntary (9.3.3) because these people are not working by choice or due to market adjustment mechanisms.
- Includes: Frictional and Structural unemployment.
- It exists because people are either searching for better jobs or their skills are not demanded at the going wage rate.
B. Disequilibrium Unemployment (Involuntary Unemployment)
This occurs when the wage rate is held above the equilibrium level (W*), meaning the supply of labour (workers willing to work) exceeds the demand for labour (jobs available) at that wage.
- Includes: Cyclical unemployment (due to low AD, which shifts the demand for labour curve left) and unemployment caused by high minimum wages or powerful trade unions (which artificially hold wages up).
- Workers experiencing this are defined as involuntarily unemployed (9.3.3)—they are willing to work at the going wage but cannot find a job.
Section 3: Full Employment and the Natural Rate (A Level Extension)
In macroeconomics, full employment does not mean 0% unemployment. This is a crucial distinction!
3.1 Defining Full Employment (9.3.1)
Full Employment is the level of employment that exists when the economy is producing at its maximum potential output (on the PPC or the LRAS curve). At this point, all available resources, including labour, are fully utilised.
At full employment, the only unemployment remaining is equilibrium unemployment (frictional and structural). The economy cannot eliminate these types easily, even when booming.
3.2 The Natural Rate of Unemployment (NRU) (9.3.4)
Definition: The Natural Rate of Unemployment (NRU) is the rate of unemployment that exists when the labour market is in equilibrium. It is the minimum rate of unemployment that an economy can sustain without causing accelerating inflation.
- The NRU consists solely of structural, frictional, and seasonal unemployment (all considered equilibrium/voluntary unemployment).
- If the actual unemployment rate is below the NRU, it means demand for labour is extremely high, putting intense upward pressure on wages and prices (inflation).
Determinants of the NRU (9.3.4):
The factors that determine how high the NRU is are primarily related to the rigidity and efficiency of the labour market. Key determinants include:
- Labour Mobility: How easy it is for workers to move jobs (occupational) and location (geographical). Low mobility leads to a higher NRU.
- Level of Unemployment Benefits: Generous benefits reduce the urgency to seek work, increasing frictional unemployment and thus raising the NRU.
- Power of Trade Unions/Regulation: High union power or restrictive labour laws can keep wages artificially high, leading to more structural unemployment.
- Availability of Information: If job seekers don't know where the vacancies are, it takes longer to find a job (higher frictional unemployment).
3.3 The Scarring Effect: Hysteresis (9.3.2)
Hysteresis is a term used to describe a situation where a period of high unemployment (often cyclical) causes the NRU itself to rise permanently.
Analogy: A bicycle chain that has rusted during a long winter is difficult to get moving again.
Why does this happen?
- Loss of Human Capital: Long-term unemployed workers lose skills, motivation, and confidence, making them less attractive to employers.
- Discouraged Workers: Extended unemployment forces people out of the labour force entirely, reducing the effective labour supply.
Section 4: Consequences of Unemployment (4.5.4)
Unemployment imposes significant costs on individuals, the economy, and society.
4.1 Economic Consequences
- Lost Output (GDP): Unemployment means resources (labour) are wasted, causing the economy to operate below its PPC or potential output. This loss of national income is arguably the biggest economic cost.
- Increased Burden on Government Finances:
- Government spending increases due to higher spending on unemployment benefits and welfare payments (transfer payments).
- Government revenue decreases because fewer people are working and paying income tax, and less is earned through consumption taxes (VAT/GST).
- Increased Income Inequality: The unemployed fall behind, widening the gap between the rich and the poor.
- Lower Investment: High unemployment usually signals low demand, discouraging firms from investing in new capital.
4.2 Social Consequences
- Psychological Costs: Unemployment often leads to stress, anxiety, and depression for the affected individuals and their families.
- Social Disorder: Higher crime rates, homelessness, and political instability can sometimes be linked to persistently high unemployment.
- Erosion of Human Capital: The skills of the long-term unemployed workers deteriorate (hysteresis), making their return to work even harder.
Section 5: Labour Market Dynamics (A Level Mobility)
High structural and frictional unemployment often indicate problems with the flexibility of the labour market, particularly the mobility of labour (9.3.6).
5.1 Forms of Labour Mobility
- Occupational Mobility: The ease with which workers can change jobs or occupations, especially moving from one industry to another requiring different skills.
- Geographical Mobility: The ease with which workers can move location to find employment in a different region or country.
5.2 Factors Affecting Labour Mobility (9.3.6)
These factors explain why some types of unemployment last longer than others:
Factors Reducing Occupational Mobility:
- Lack of education or transferrable skills.
- High cost or time requirement for retraining.
- Specific vocational qualifications or licensing required for certain jobs.
Factors Reducing Geographical Mobility:
- Housing Costs: High prices or difficulty selling a current home can prevent movement.
- Family Ties/Social Factors: Reluctance to move away from family, friends, or established social networks.
- Language and Cultural Barriers: Especially when moving internationally.
Section 6: Policies to Reduce Unemployment (A Level Policy Evaluation 9.3.7)
The golden rule of unemployment policy is: The policy must match the cause. You wouldn't use a fiscal policy (AD boost) to fix structural unemployment (a skills problem).
6.1 Policies to Reduce Cyclical (Demand-Deficient) Unemployment
Since this type is caused by low Aggregate Demand (AD), we use Demand-Side Policies to shift the AD curve rightwards.
- Fiscal Policy (5.2): Increasing Government Spending (G) or cutting Taxes (T).
- Effectiveness: Quick impact, especially if the economy is far below potential.
- Limitation: Can lead to demand-pull inflation if the economy is close to full employment.
- Monetary Policy (5.3): Cutting Interest Rates (which boosts Consumption (C) and Investment (I)).
- Effectiveness: Cheap for the government to implement.
- Limitation: Can be ineffective during a severe recession (Liquidity Trap) or if consumer confidence is very low.
6.2 Policies to Reduce Structural, Frictional, and NRU (Equilibrium) Unemployment
These are supply-side problems related to the inefficiency of the labour market. We use Supply-Side Policies (5.4) to shift the Long-Run Aggregate Supply (LRAS) curve rightwards and improve the NRU.
- Education and Training (Occupational Mobility): Government subsidies for vocational training or improving the curriculum in schools to match industrial needs.
- Effectiveness: Directly addresses structural mismatch.
- Limitation: Expensive, and the results take a long time (a significant time lag).
- Reducing Welfare Benefits (Frictional/NRU): Lowering the level or duration of unemployment benefits.
- Effectiveness: Increases the incentive for the unemployed to accept available jobs quickly.
- Limitation: Raises concerns about equity and poverty, potentially harming those genuinely struggling to find work.
- Improving Job Information (Frictional): Funding job centres or online databases to match vacancies with job seekers faster.
- Effectiveness: Reduces search time efficiently.
- Limitation: Only effective for frictional unemployment, not if the structural problem is severe.
- Infrastructure Development (Geographical Mobility): Building better transport links (roads, rail) to make it easier for workers to commute to areas with job openings.
- Lowering Income Tax: Incentivises work over leisure, increasing the supply of labour and reducing the NRU.
6.3 Policy Conflicts and Evaluation
Often, policies designed to fix one type of unemployment conflict with other objectives:
- Demand vs. Inflation: Expansionary Demand-Side Policies reduce cyclical unemployment but risk causing inflation (a trade-off often shown by the Phillips Curve, though that specific relationship is covered later).
- Efficiency vs. Equity: Reducing benefits or trade union power lowers the NRU (improving efficiency) but can increase income inequality (reducing equity).
