Welcome to the Macroeconomy: Employment and Unemployment
Hello! This chapter is incredibly important. When a government looks at how well the economy is doing, the level of employment is one of the key indicators. Understanding unemployment isn't just about counting job losses; it's about diagnosing why resources (labour) are being wasted and figuring out how to get the economy back to full health.
Don't worry if some of the terminology seems dense. We will break down the different types of unemployment and the policy tools used to fix them, focusing on clear definitions and real-world examples.
1. Defining Employment and Unemployment (AS Level Review)
1.1 Key Definitions
To understand unemployment, we first need to define the Labour Force.
- Working Population / Labour Force: This includes all people of working age who are economically active—meaning they are currently employed OR unemployed but actively seeking work.
- Employment: Individuals in the Labour Force who are currently holding a job (either full-time or part-time).
- Unemployment (4.5.1): Individuals in the Labour Force who are without a job but are actively seeking work and are available to start immediately.
1.2 Measuring Unemployment (4.5.2)
Governments use statistics to measure how severe the problem is. The primary measure is the Unemployment Rate:
Unemployment Rate \( = \frac{\text{Number of Unemployed}}{\text{Labour Force}} \times 100 \)
Methods and Difficulties in Measurement
There are typically two main methods used, and both have limitations:
1. Claimant Count (or Registered Unemployed):
- Counts people claiming unemployment-related benefits from the government.
- Difficulty: This often understates the true level of unemployment, as many unemployed people may not be eligible for or choose not to claim benefits.
2. Labour Force Survey (LFS) / Standardized Measure:
- A survey asking a sample of households whether individuals are actively looking for work, regardless of whether they are claiming benefits. This is the internationally comparable standard.
-
Difficulty: Still misses two key problems:
(i) Hidden Unemployment: People who have stopped actively looking for work (discouraged workers) because they believe no jobs are available. They are not counted in the Labour Force and thus not counted as unemployed.
(ii) Underemployment: People who are working, but their jobs are part-time when they want full-time work, or they are overqualified for the jobs they hold (e.g., an engineer working as a delivery driver). They are counted as employed, even though their labour is not being used fully.
Key Takeaway: Measuring unemployment is complex. The official rate often underestimates the true underutilisation of labour because it ignores discouraged workers and those who are underemployed.
2. Causes and Types of Unemployment (4.5.3)
Unemployment is not a single problem; it comes in several forms, each requiring a different policy solution. Think of it like a doctor needing to know if your fever is caused by a cold (frictional) or a severe infection (cyclical).
2.1 Frictional Unemployment
This is short-term unemployment that occurs when workers are temporarily between jobs, moving geographically, or waiting to start a new job.
- Example: A student graduates and spends two months searching for the perfect graduate role.
- Analogy: It’s like the brief period between when you finish one TV show and start another—you are actively searching but temporarily not watching.
2.2 Structural Unemployment
This is the most serious non-cyclical type. It occurs when there is a permanent mismatch between the skills workers possess and the skills employers demand, or a mismatch in location.
- Caused by industrial change (decline of old industries like coal mining) or lack of labour mobility (see Section 5).
- Example: Factory workers losing jobs due to robot automation and lacking the skills for the high-tech services sector.
2.3 Cyclical (Demand-Deficient) Unemployment
This is unemployment caused by a lack of Aggregate Demand (AD) in the economy. When the economy enters a recession, firms see falling demand and consequently cut production and lay off workers.
- Cyclical unemployment rises sharply during a recession and falls during a boom.
- Example: During the 2008 financial crisis, consumer spending plummeted, leading to widespread layoffs in construction and retail.
2.4 Seasonal and Technological Unemployment
- Seasonal: Affects workers whose jobs depend on the time of year (e.g., agricultural workers after harvest, or ski instructors in summer).
- Technological: A subset of structural unemployment where jobs are specifically lost due to automation or the introduction of new, labour-saving technology (e.g., automated checkout lines replacing cashiers).
Use this mnemonic to recall the five types of unemployment:
Frictional, Structural, Cyclical, Seasonal, Technological.
3. Consequences of Unemployment (4.5.4)
High unemployment has severe negative impacts on the economy and society.
3.1 Economic Consequences
- Loss of Potential Output: The most direct cost. Unemployed labour means the economy is operating inside its Production Possibility Curve (PPC). GDP is lower than it could be. This results in a loss of economic welfare.
- Fiscal Burden: Government spending increases due to higher costs of unemployment benefits and welfare payments (Transfer Payments). Simultaneously, government revenue from income tax and indirect taxes falls, worsening the budget deficit.
- Downward Pressure on Wages: A high supply of unemployed labour generally depresses wage rates for those who are employed, potentially increasing inequality.
- Loss of Human Capital: Long-term unemployment can lead to a deterioration of workers' skills (skills atrophy), making them less employable even when the economy recovers.
3.2 Social Consequences
- Increased Poverty and Inequality: Unemployed individuals lose income, leading to a rise in absolute and relative poverty.
- Social Instability: Higher unemployment is often correlated with increased crime rates, stress-related health problems, and social unrest.
Did you know? The economic cost of long-term structural unemployment is far greater than short-term frictional unemployment, as structural unemployment means human capital is permanently lost or devalued.
4. Advanced Concepts of Employment (A Level)
4.1 Full Employment and NRU (9.3.1, 9.3.4)
Full Employment (9.3.1): This is not 0% unemployment. Full employment is the level of employment achieved when the economy is producing at its maximum sustainable output (Potential GDP). At this point, all those who are willing and able to work have jobs.
The only unemployment that exists at full employment is that which cannot be eliminated by simply boosting demand—namely, frictional and structural unemployment.
This leads us to the concept of the Natural Rate of Unemployment (NRU) (9.3.4):
- Definition: The rate of unemployment that exists when the labour market is in equilibrium. It comprises frictional, structural, seasonal, and technological unemployment. It is the rate below which inflation tends to accelerate.
- Significance: If a government tries to push unemployment below the NRU using demand-side policies, the primary result will be accelerating inflation, not sustained real output growth.
-
Determinants of NRU (9.3.4): The NRU is determined by supply-side factors, such as:
- The level of labour mobility (occupational and geographical).
- The efficiency of the labour market (e.g., job information systems).
- The level of skills and training in the economy.
- The generosity of unemployment benefits (if benefits are too high, the incentive to seek work falls).
- Trade union power (which can lead to wages above the market equilibrium).
4.2 Equilibrium and Disequilibrium Unemployment (9.3.2)
This classification helps us link unemployment types to the overall labour market model (supply and demand for labour).
4.2.1 Equilibrium Unemployment (Voluntary) (9.3.3)
This occurs when the number of people seeking jobs equals the number of jobs available, but some people are still unemployed by choice or due to market friction.
- This is essentially the NRU.
- It is largely Voluntary Unemployment (9.3.3)—workers choosing not to take available jobs (frictional) or lacking the required skills (structural).
4.2.2 Disequilibrium Unemployment (Involuntary) (9.3.3)
This occurs when the supply of labour exceeds the demand for labour. This means that at the prevailing wage rate, more people want to work than there are jobs available.
- The main type is Cyclical Unemployment (caused by falling AD).
- It is largely Involuntary Unemployment (9.3.3)—workers are willing to work at the current wage but cannot find a job.
- Disequilibrium can also be caused by minimum wage laws or strong trade unions setting wages above the equilibrium level (a classic microeconomic intervention causing macroeconomic disequilibrium).
Hysteresis (9.3.2):
This is a high-level concept. Hysteresis means that a temporary shock (like a cyclical recession) can have permanent effects on the NRU.
Step-by-step process: A severe recession leads to prolonged high cyclical unemployment \( \rightarrow \) Workers become long-term unemployed \( \rightarrow \) They lose skills and motivation (skills atrophy) \( \rightarrow \) They are now structurally unemployed (even when AD recovers).
The original cyclical unemployment has become structural, causing the NRU to shift outwards/upwards permanently.
5. Labour Market Dynamics (9.3.5, 9.3.6)
5.1 Patterns and Trends (9.3.5)
Candidates should be aware that unemployment rates are not uniform. Trends often show:
- Regional Disparities: Areas traditionally reliant on declining industries (e.g., heavy manufacturing regions) typically have persistently higher structural unemployment than service-oriented capital cities.
- Age and Skill Gaps: Youth unemployment is often higher, and those with lower qualifications are often disproportionately affected by job losses.
- Gender/Ethnic Gaps: Statistical trends often show disparities in employment rates across different demographic groups.
- Long-Term Trends: Many developed economies have seen a trend toward higher NRU (due to globalisation and automation) alongside an increase in underemployment.
5.2 Mobility of Labour (9.3.6)
The ability of the workforce to move between jobs and locations is crucial in determining the level of structural and frictional unemployment.
1. Geographical Mobility: The ease with which workers can move from one area to another to find work.
- Factors affecting mobility: Cost of housing (high price of moving), family and social ties, imperfect information about jobs elsewhere, and regional differences in cost of living.
2. Occupational Mobility: The ease with which workers can switch between different occupations (i.e., changing from being a factory worker to a web developer).
- Factors affecting mobility: Lack of appropriate skills/qualifications, cost and time of training/retraining, and age (older workers may find it harder to switch).
Key Takeaway: Low labour mobility contributes directly to high structural and frictional unemployment.
6. Policies to Reduce Unemployment (9.3.7)
The effectiveness of a policy depends entirely on the type of unemployment being targeted. Using the wrong policy is often ineffective or causes inflation.
6.1 Addressing Disequilibrium/Cyclical Unemployment
Since cyclical unemployment is caused by a lack of Aggregate Demand (AD), we use Demand-Side Policies (Expansionary Fiscal or Monetary Policy).
Expansionary Fiscal Policy
Increase G (Government Spending) or decrease T (Taxes).
- Effectiveness: Directly boosts AD, leading to increased output and employment.
- Limitation: Can lead to demand-pull inflation if the economy is close to full capacity (NRU). Also, government debt increases.
Expansionary Monetary Policy
Decrease interest rates.
- Effectiveness: Lowers the cost of borrowing, boosting Investment (I) and Consumption (C), thus increasing AD.
- Limitation: May be ineffective during a deep recession if consumers and firms are unwilling to borrow (the liquidity trap). Also, risks inflation.
6.2 Addressing Equilibrium/Structural/Frictional Unemployment
Since these types are caused by labour market imperfections and rigidities (the NRU), we use Supply-Side Policies. These aim to shift the Long-Run Aggregate Supply (LRAS) curve outwards and reduce the NRU.
Supply-Side Policy Tools
-
Training and Education: Government funding for retraining programmes (9.3.7).
- Effectiveness: Directly tackles structural unemployment by improving occupational mobility.
- Limitation: High cost, long time lag (it takes years to retrain a large workforce).
-
Improving Information: Better government job centres or online systems.
- Effectiveness: Reduces frictional unemployment by matching jobs and seekers faster.
-
Infrastructure Development: Investment in transport links (roads, rail).
- Effectiveness: Improves geographical mobility, allowing workers to commute further for jobs.
-
Labour Market Deregulation: Reducing trade union power or reducing unemployment benefits.
- Effectiveness: Increases labour market flexibility; workers are more willing to move or accept lower wages, reducing the NRU.
- Limitation: Highly controversial; may increase poverty and inequality.
Common Mistake to Avoid:
If the economy is suffering from structural unemployment, boosting AD through lower interest rates (Monetary Policy) will only cause inflation because the economy’s maximum capacity (LRAS) has not changed. You must use Supply-Side policies to fix structural issues.
The goal is achieving Full Employment, meaning unemployment is reduced to the Natural Rate (NRU).
Cyclical (Involuntary/Disequilibrium) unemployment needs Demand-Side Policies.
Structural and Frictional (Voluntary/Equilibrium) unemployment needs Supply-Side Policies (focused on training and mobility).
