Full Employment
Definition of Full Employment
Full employment is a situation in which nearly everyone who is willing and able to work at the prevailing wage rate can find a job, apart from those who are temporarily between jobs or experiencing other forms of unavoidable unemployment.
→ Full employment does not mean zero unemployment.
→ Some people may be changing jobs, entering the labour force for the first time or acquiring new skills.
→ Full employment occurs when unemployment is mainly limited to frictional and structural unemployment, with no significant cyclical unemployment.
Example: An economy may be considered close to full employment even if some workers are temporarily searching for a new job or cannot immediately find work matching their qualifications.
Equilibrium and Disequilibrium Unemployment
Equilibrium Unemployment
Equilibrium unemployment occurs when the labour market is in equilibrium, meaning the quantity of labour supplied equals the quantity of labour demanded at the prevailing real wage rate.
→ Workers willing and able to work at the equilibrium wage can find employment.
→ Some unemployment may still exist because workers are changing jobs or lack the skills required for available vacancies.
→ It is associated with frictional and structural unemployment.
Example: A graduate spends two months searching for a suitable job while employers continue recruiting workers with the right qualifications.
Disequilibrium Unemployment
Disequilibrium unemployment occurs when the labour market is not in equilibrium, so the quantity of labour supplied does not equal the quantity of labour demanded.
→ It can occur when wages are held above the equilibrium level, causing excess supply of labour.
→ More people want to work than firms are willing to employ.
→ It can also arise when aggregate demand falls, reducing firms’ demand for workers.
Example: If a minimum wage is set significantly above the equilibrium wage in a competitive labour market, some workers may be willing to work at that wage but unable to find jobs.
Hysteresis
Hysteresis occurs when temporary unemployment becomes persistent and raises the long-term or natural rate of unemployment.
It means that a period of high unemployment can have lasting effects on the labour market, even after the original cause has disappeared.
How hysteresis occurs:
→ A recession reduces demand for goods and services.
→ Firms reduce production and make workers redundant.
→ Workers remain unemployed for a long period.
→ Their skills may become outdated, and they may lose work experience, confidence and professional contacts.
→ Employers may become less willing to recruit long-term unemployed workers.
→ These workers find it harder to obtain jobs even when the economy recovers.
→ The natural rate of unemployment may rise.
Example: A factory worker loses a job during a recession. After several years without employment, the worker’s technical skills become outdated. When demand recovers, the factory may recruit workers with more recent training instead.
Why hysteresis matters:
→ A recession may cause unemployment that continues long after economic growth returns.
→ Policies that help unemployed people retrain and return to work quickly can prevent temporary unemployment from becoming long-term unemployment.
→ Simply increasing aggregate demand may not be sufficient if workers’ skills and employability have deteriorated.
Voluntary and Involuntary Unemployment
Voluntary Unemployment
Voluntary unemployment occurs when people are unemployed because they choose not to accept the jobs available at the prevailing wage rates and working conditions.
Possible reasons include:
→ Workers reject jobs because wages are too low for them.
→ Individuals choose to continue searching for a more suitable job.
→ Workers may prefer further education, training or time away from employment.
→ Some people may be unwilling to accept jobs because of working hours, location or conditions.
Example: A qualified accountant rejects an available job because the salary is below the amount they are willing to accept and continues searching for a better-paid position.
Important distinction: A person who rejects one unsuitable job is not necessarily unemployed voluntarily if they remain unable to find any acceptable employment. The classification depends on the circumstances.
Involuntary Unemployment
Involuntary unemployment occurs when people are willing and able to work at the prevailing wage rate but cannot find employment.
Possible reasons include:
→ Firms reduce production because demand for their products falls.
→ Workers lack the skills required for available vacancies.
→ Wages may be held above the equilibrium level.
→ There may be too few job vacancies in a particular region or industry.
Example: A trained construction worker is willing to work at the prevailing wage but cannot find employment because building firms have reduced their projects.
Difference Between Voluntary and Involuntary Unemployment
| Voluntary unemployment | Involuntary unemployment |
|---|---|
| The individual chooses not to accept available work under the conditions offered. | The individual wants to work but cannot obtain a suitable job. |
| May be linked to wage expectations, preferences or job conditions. | May be caused by weak demand, skill mismatches or labour-market rigidities. |
| Policies may focus on incentives, information and job matching. | Policies may focus on job creation, training and improving labour-market flexibility. |
The Natural Rate of Unemployment
Definition
The natural rate of unemployment is the rate of unemployment that exists when the economy is operating at its normal sustainable level of output, without cyclical unemployment.
It mainly consists of frictional and structural unemployment.
→ Frictional unemployment occurs while people move between jobs or enter the labour market.
→ Structural unemployment occurs when workers’ skills, locations or experience do not match the requirements of available jobs.
→ The natural rate is not zero because workers and jobs cannot always be matched immediately.
Determinants of the Natural Rate of Unemployment
1. Occupational mobility of labour
→ If workers can easily acquire new skills and qualifications, they can move between occupations.
→ Better occupational mobility reduces structural unemployment.
→ Poor access to education and retraining may increase the natural rate.
Example: Training unemployed retail workers in digital sales and logistics may help them obtain jobs in expanding industries.
2. Geographical mobility of labour
→ Workers who can move to regions with more job opportunities are more likely to find employment.
→ High housing costs, relocation expenses and family commitments may prevent workers from moving.
→ Low geographical mobility can increase regional unemployment and the natural rate.
3. Availability of information about jobs
→ Job websites, recruitment agencies and employment services help workers identify vacancies.
→ Better information reduces the time spent searching for jobs.
→ Poor information can increase frictional unemployment.
4. Unemployment benefits and other financial incentives
→ Benefits provide income security while people search for work.
→ If benefits are withdrawn sharply as earnings increase, some workers may have less financial incentive to accept low-paid employment.
→ However, benefits can also help workers search for jobs that better match their skills, potentially improving productivity.
→ The effect on the natural rate depends on benefit design, job availability and labour-market conditions.
5. Trade union power and wage-setting arrangements
→ Strong collective bargaining may raise wages and improve working conditions.
→ If wages remain above the equilibrium level in a competitive labour market, firms may employ fewer workers.
→ However, unions can also improve training, communication and workplace productivity, so the overall effect is not always negative.
6. Minimum wage legislation
→ A minimum wage above the competitive equilibrium may increase the quantity of labour supplied beyond the quantity demanded.
→ This can contribute to unemployment among some groups, particularly if their productivity is low relative to the wage.
→ The effect depends on the level of the minimum wage, productivity and the structure of the labour market.
7. Education and training
→ Education and training help workers develop skills demanded by employers.
→ Effective training reduces skill mismatches and structural unemployment.
→ Outdated qualifications or a shortage of relevant skills may increase the natural rate.
8. Labour-market flexibility
→ Flexible working arrangements, effective recruitment systems and easier movement between jobs can improve job matching.
→ Excessive hiring costs or rigid employment arrangements may discourage some firms from recruiting.
→ However, flexibility must be balanced against workers’ rights, job security and fair treatment.
Policy Implications of the Natural Rate of Unemployment
→ Policies that increase aggregate demand can reduce cyclical unemployment, particularly during a recession.
→ However, they may have limited success in reducing frictional and structural unemployment.
→ If the economy is already near full employment, further increases in aggregate demand may mainly create inflationary pressure rather than permanently reduce unemployment.
→ Supply-side policies such as training, education, job-search assistance and improving labour mobility can reduce the natural rate.
→ Reducing the natural rate allows an economy to sustain a higher level of employment without generating excessive inflationary pressure.
Example: If an economy’s natural rate is 6%, increasing demand may temporarily reduce unemployment below 6%. However, if the natural rate remains unchanged, this lower rate may not be sustainable and could create upward pressure on wages and prices.
Patterns and Trends in Employment and Unemployment
Employment and unemployment vary across countries, industries, regions, age groups and time periods.
Changes Over the Business Cycle
During an economic expansion:
→ Aggregate demand rises.
→ Firms increase production to meet higher demand.
→ Firms recruit more workers.
→ Employment rises and cyclical unemployment generally falls.
During a recession:
→ Aggregate demand falls.
→ Firms experience lower sales and may accumulate unsold stock.
→ Firms reduce output, recruitment and working hours.
→ Some workers are made redundant.
→ Unemployment generally rises.
Differences Between Groups of Workers
1. Age
→ Young people may experience higher unemployment because they lack work experience and job-specific skills.
→ New entrants often spend time searching for their first job.
→ Older workers may face difficulties if their skills become outdated or if employers are reluctant to recruit them.
2. Qualifications and skills
→ Workers with skills in high demand may experience lower unemployment.
→ Workers whose skills are no longer required may experience structural unemployment.
→ Technological change can increase demand for some occupations while reducing demand for others.
3. Gender
→ Employment and unemployment patterns may differ between men and women because of differences in occupational choices, unpaid care responsibilities, access to childcare, discrimination and social expectations.
→ These differences vary across countries and over time.
4. Region
→ Regions with expanding industries may attract investment and experience rising employment.
→ Regions dependent on declining industries may experience persistent unemployment.
→ Differences in transport, infrastructure, housing and access to education can affect regional employment.
5. Industry and occupation
→ Employment may increase in expanding sectors such as healthcare or digital services.
→ Employment may fall in industries affected by automation, declining demand or international competition.
→ Workers may need retraining to move into expanding occupations.
Structural and Long-Term Trends
→ Automation can replace workers performing routine tasks while increasing demand for workers with technical skills.
→ Globalisation can increase employment in export industries but reduce employment in industries facing stronger import competition.
→ Changes in consumer preferences can expand some industries and cause others to contract.
→ An ageing population may reduce the proportion of people of working age, while increasing demand for healthcare workers.
→ The growth of part-time, temporary and gig work may change the type and security of employment available.
Measuring Unemployment
The unemployment rate measures the percentage of the labour force that is unemployed.
Unemployment rate=Labour forceNumber unemployed×100
The labour force consists of employed people and unemployed people who are actively seeking and available for work, according to the statistical definition being used.
Example:
A country has:
- Employed people = 9 million
- Unemployed people = 1 million
Labour force = 9 million + 1 million = 10 million.
Unemployment rate=101×100=10%
Important points when interpreting unemployment data:
→ A fall in the unemployment rate does not always mean that employment has increased. People may have stopped looking for work and left the labour force.
→ Some unemployed people may be underemployed, working fewer hours than they want or in jobs below their skill level.
→ Informal employment and differences in how countries collect data can make international comparisons difficult.
→ The unemployment rate should therefore be considered alongside employment rates, labour-force participation, hours worked and underemployment.
Mobility of Labour
Labour mobility is the ability of workers to move between different jobs, occupations or geographical locations.
Geographical Mobility
Geographical mobility is the ability of workers to move from one geographical area to another to obtain employment.
Example: A worker moves from a region with few manufacturing jobs to a city where factories are recruiting.
Factors affecting geographical mobility:
→ Housing costs: Expensive housing in areas with more vacancies may prevent workers from moving.
→ Relocation costs: Travel, moving expenses and deposits can make relocation difficult.
→ Family commitments: Children’s education, caring responsibilities and a partner’s employment may limit movement.
→ Transport infrastructure: Reliable transport can allow workers to access jobs without relocating.
→ Information: Knowledge of vacancies and wages in other regions encourages mobility.
→ Cultural and language barriers: Workers may find it difficult to adapt to different languages, customs or working environments.
→ Government policies: Housing support, relocation assistance and investment in transport can improve geographical mobility.
Occupational Mobility
Occupational mobility is the ability of workers to move from one type of job or occupation to another.
Example: A worker whose job in traditional manufacturing has disappeared retrains to become a maintenance technician for automated machinery.
Factors affecting occupational mobility:
→ Education and qualifications: Workers with relevant qualifications may move more easily into other occupations.
→ Training opportunities: Affordable retraining helps workers acquire new skills.
→ Transferable skills: Communication, problem-solving and digital skills can be useful across several occupations.
→ Cost and time of training: Long and expensive training may discourage workers from changing occupations.
→ Age and experience: Some workers may find it harder to change careers after many years in a specialised role, although this depends on the occupation and individual.
→ Availability of vacancies: Workers are more likely to retrain when there is strong demand for the new occupation.
→ Professional regulations: Licensing and qualification requirements may restrict entry into certain occupations.
Why Labour Mobility Matters
→ Higher labour mobility allows workers to move from declining industries to expanding industries.
→ Vacancies are filled more quickly, reducing frictional and structural unemployment.
→ Firms gain access to workers with the skills they need.
→ Labour is allocated more efficiently, potentially increasing productivity and economic growth.
However:
→ Training and relocation can be expensive.
→ Some workers may be unable to move because of family or financial constraints.
→ Mobility may take time, so unemployment may persist even when vacancies exist elsewhere.
→ Greater mobility alone cannot solve unemployment caused by insufficient aggregate demand.
Policies to Reduce Unemployment and Their Effectiveness
The effectiveness of an unemployment policy depends on the cause of unemployment, the state of the economy, the time available for implementation and the costs involved.
Expansionary Fiscal Policy
Expansionary fiscal policy involves increasing government spending, reducing taxes or using a combination of both to increase aggregate demand.
How it reduces unemployment:
→ Government spending or tax reductions increase spending in the economy.
→ Firms receive more orders and experience higher sales.
→ Firms increase production.
→ Firms employ more workers to meet higher demand.
→ Cyclical unemployment falls.
Example: Government spending on roads and public infrastructure creates jobs directly in construction and indirectly in suppliers of cement, steel and transport services.
Advantages:
→ Can reduce cyclical unemployment during a recession.
→ Infrastructure spending may create jobs and improve long-term productive capacity.
→ The multiplier effect may increase national income by more than the initial increase in spending.
Limitations:
→ Government spending can increase public borrowing and debt.
→ Policies may take time to plan and implement.
→ If the economy is near full employment, extra demand may cause inflation rather than a large increase in employment.
→ It may not solve structural unemployment caused by a mismatch of skills.
Effectiveness: Most useful when unemployment is caused by weak aggregate demand and firms have spare capacity.
Expansionary Monetary Policy
Expansionary monetary policy involves reducing interest rates or using other measures to increase the availability of credit and encourage spending.
How it reduces unemployment:
→ Lower interest rates reduce the cost of borrowing.
→ Households may increase consumption, especially on credit-financed goods.
→ Firms may increase investment because borrowing becomes cheaper.
→ Aggregate demand rises.
→ Firms increase production and demand more labour.
→ Cyclical unemployment falls.
Advantages:
→ Can encourage consumption and investment across the economy.
→ Lower borrowing costs may help firms expand and recruit workers.
→ Monetary policy can often be adjusted as economic conditions change.
Limitations:
→ If consumer and business confidence is low, households and firms may not increase spending or investment.
→ Lower interest rates may have limited effects when borrowing is already weak.
→ The effects can take time to influence output and employment.
→ It may create inflationary pressure if aggregate demand rises too strongly.
Effectiveness: Most useful when unemployment is caused by weak demand and lower interest rates can stimulate spending.
Supply-Side Policies
Supply-side policies aim to improve the productive capacity and efficiency of the economy. Some also directly improve workers’ ability to find employment.
Education and Training
→ Government and firms provide training in skills demanded by employers.
→ Workers become more productive and employable.
→ Skill mismatches are reduced.
→ Structural unemployment may fall.
Example: Retraining workers in digital technology, healthcare support or advanced manufacturing may help them move into occupations with vacancies.
Advantages: Improves long-term employability and productivity.
Limitations: Training costs money, results may take time and courses may be ineffective if they do not match employers’ needs.
Improving Labour Mobility
→ Relocation assistance, affordable housing and improved transport help workers reach areas with vacancies.
→ Occupational retraining helps workers move between industries.
→ Vacancies are filled more quickly.
→ Structural and frictional unemployment may fall.
Limitations: Workers may be unwilling or unable to relocate, and mobility cannot create jobs where there is insufficient demand.
Reducing Barriers to Employment
→ Simplifying recruitment procedures or reducing unnecessary employment costs may encourage firms to hire.
→ Lower hiring costs can make firms more willing to recruit additional workers.
→ Employment may rise if the benefits of hiring exceed the additional costs.
Limitations: Reducing worker protections can lead to job insecurity, poor working conditions or lower incomes. The effect depends on the type of regulation and the response of firms.
Encouraging Enterprise and Investment
→ Support for start-ups, access to finance and a stable business environment can encourage new businesses.
→ New businesses create jobs directly.
→ Successful firms may expand and recruit additional workers.
Limitations: Some new businesses fail, financial support may be poorly targeted and the jobs created may not match the skills of unemployed workers.
Employment Subsidies
An employment subsidy is financial assistance given by the government to employers for hiring eligible workers.
How it reduces unemployment:
→ The effective cost of employing eligible workers falls.
→ Hiring becomes more attractive to firms.
→ Firms may recruit additional workers.
→ Unemployment among targeted groups may fall.
Example: A temporary subsidy for hiring long-term unemployed people may encourage firms to offer them employment.
Advantages:
→ Can target groups facing particularly high unemployment.
→ May help unemployed workers gain experience and develop skills.
→ Can reduce the long-term costs associated with persistent unemployment.
Limitations:
→ Government spending is required.
→ Some firms may receive subsidies for workers they would have hired anyway, creating a deadweight cost.
→ Firms may replace existing workers with subsidised workers, or dismiss workers when the subsidy ends.
Effectiveness: More effective when subsidies are targeted, temporary where appropriate and linked to genuine additional employment.
Improving Job Information and Employment Services
→ Employment agencies, career guidance and job-matching websites connect jobseekers with vacancies.
→ Better information reduces the time workers spend searching.
→ Firms fill vacancies more quickly.
→ Frictional unemployment may fall.
Advantages: Often relatively quick and inexpensive compared with long-term retraining programmes.
Limitations: Job information cannot solve a shortage of vacancies or major skill mismatches on its own.
Reducing Unemployment Benefits or Changing Benefit Design
→ Reducing the financial disincentive to accept work may encourage some people to search more actively or accept available jobs.
→ Gradual withdrawal of benefits as earnings rise can help ensure that taking a job increases disposable income.
→ This may reduce unemployment caused partly by weak financial incentives.
Limitations:
→ Cutting benefits may increase poverty and hardship.
→ If jobs are unavailable, lower benefits may not increase employment.
→ Benefits provide income security and may allow people to search for work that matches their skills.
Effectiveness: Benefit reform is more likely to work when suitable jobs are available and workers can realistically access them.
Public Works Programmes
Public works programmes involve government-funded projects that directly employ workers, such as road construction, drainage, public transport improvements or environmental restoration.
How they reduce unemployment:
→ The government funds a project.
→ Workers are hired directly to carry it out.
→ Their incomes increase, supporting household consumption.
→ Suppliers may receive additional orders and employ more workers.
Advantages:
→ Can provide employment relatively quickly when projects are ready.
→ May improve infrastructure and create longer-term economic benefits.
Limitations:
→ Projects can be expensive.
→ Poor planning may create jobs that disappear when the project ends.
→ The skills required may not match those of the unemployed workers.
Comparison of Unemployment Policies
| Policy | Main type of unemployment targeted | Main limitation |
|---|---|---|
| Expansionary fiscal policy | Cyclical | May increase borrowing and inflation |
| Expansionary monetary policy | Cyclical | May be ineffective when confidence is low |
| Education and training | Structural | Results take time |
| Labour mobility measures | Frictional and structural | Relocation and personal barriers remain |
| Employment subsidies | Targeted unemployment | Deadweight costs and temporary effects |
| Job information and employment services | Frictional | Cannot create enough vacancies by itself |
| Benefit reform | Some incentive-related unemployment | May increase hardship without creating jobs |
| Public works programmes | Cyclical and targeted unemployment | Can be costly and temporary |
Evaluating the Effectiveness of Unemployment Policies
No single policy is likely to eliminate every type of unemployment. The best approach depends on the underlying cause.
→ If unemployment is cyclical: Expansionary fiscal or monetary policy may be effective because it increases aggregate demand.
→ If unemployment is structural: Education, retraining and improved occupational mobility are more suitable because they address skill mismatches.
→ If unemployment is frictional: Better job information and employment services can help workers find jobs more quickly.
→ If unemployment is concentrated in particular groups: Targeted employment subsidies, apprenticeships and training may be more effective than general measures.
→ If unemployment is caused by hysteresis: Early intervention, retraining and support for long-term unemployed people can help prevent a temporary setback from becoming permanent.
→ If the economy is near full employment: Policies that improve skills, productivity and labour mobility are generally more suitable than simply increasing aggregate demand, which may mainly raise prices.
Overall judgement: A combination of policies is often most effective. For example, expansionary fiscal policy can increase the number of vacancies during a recession, while training and job-matching services help unemployed workers obtain those jobs. The final outcome depends on the availability of suitable jobs, the quality of policy implementation, the time required for results and the cost to the government.
