Unemployment

Unemployment: Types, Causes & Policies

Unemployment occurs when people who are of working age, able and willing to work, and actively seeking employment cannot find a job. It is a key macroeconomic indicator with significant economic, social, and political consequences.

Types of Unemployment

1. Frictional Unemployment

• Workers between jobs — searching for a better match
• Inevitable in a dynamic economy (people change careers, graduates enter the market)
• Usually short-term and voluntary (in the sense that workers choose to search)
• Reduced by: better job information (online job boards), employment agencies, lower job search costs

2. Structural Unemployment

• A mismatch between workers' skills/location and available jobs
• Caused by:
• Sectoral decline: loss of manufacturing, mining, shipbuilding in the UK
• Technological change: automation replacing routine jobs
• Geographical immobility: workers unable to move to where jobs exist (housing costs, family ties)
• Occupational immobility: workers lack skills for new industries
• Can be long-term and concentrated in specific regions (deindustrialisation of Northern England, Wales)
• Addressed by: retraining programmes, education reform, relocation subsidies, enterprise zones

3. Cyclical (Demand-Deficient) Unemployment

• Caused by a fall in aggregate demand during the downturn phase of the business cycle
• Firms reduce output and lay off workers as demand falls
• The most significant type during recessions (2008-09: UK unemployment rose from 5.2% to 8.5%)
• Keynesian view: the economy can settle at an equilibrium below full employment — government must intervene
• Classical view: wages should fall to clear the labour market — unemployment is voluntary if wages are flexible
• Addressed by: expansionary fiscal and monetary policy (increase AD)

4. Real Wage (Classical) Unemployment

• Occurs when wages are held above the market-clearing level
• Causes: minimum wage above equilibrium, trade union power, efficiency wages
• Creates excess supply of labour (more people want to work than firms want to hire)
• Classical/neoclassical economists emphasise this type
• Addressed by: reducing labour market rigidities, reforming benefits to increase work incentives

5. Seasonal Unemployment

• Regular, predictable fluctuations in demand for labour (tourism in summer, agriculture at harvest)
• Data is usually seasonally adjusted to remove this effect

The Natural Rate of Unemployment (NRU)

The NRU (or NAIRU — Non-Accelerating Inflation Rate of Unemployment) is the rate of unemployment when the labour market is in equilibrium — consistent with stable inflation.

It includes:

• Frictional unemployment (search/transition)
• Structural unemployment (mismatch)
• Seasonal unemployment

It does not include cyclical unemployment (which is zero at NRU).

Determinants of NRU:

• Labour market flexibility (ease of hiring/firing)
• Skills match between workers and vacancies
• Unemployment benefits (replacement ratio — if benefits are close to wages, less incentive to work)
• Labour market information (how easily workers find vacancies)
• Geographical/occupational mobility
• Trade union power
• Hysteresis effects (prolonged unemployment makes workers less employable)

Supply-side policies aim to reduce the NRU.

Costs of Unemployment

Economic Costs

• Lost output: economy operates inside its PPF — opportunity cost of unemployed resources
• Fiscal costs: government pays more benefits, collects less tax revenue → budget deficit widens
• Loss of human capital: skills atrophy during unemployment, reducing future productivity
• Hysteresis: prolonged unemployment may permanently raise the NRU (workers become discouraged and unemployable)
• Lower consumer spending: unemployed have lower income → reduced AD → potential deflationary spiral

Social Costs

• Poverty and deprivation: lower living standards for individuals and families
• Health impacts: stress, mental health problems, higher mortality (studies show unemployed people have worse health outcomes)
• Crime and social exclusion: unemployment correlates with higher crime rates, drug abuse
• Regional disparities: concentrated unemployment creates "left-behind" areas
• Intergenerational effects: children in workless households have poorer educational and employment outcomes

Can Any Unemployment Be Beneficial?

• Frictional unemployment enables better job matching → higher productivity
• Creative destruction (Schumpeter): some unemployment accompanies structural change that makes the economy more innovative and productive in the long run
• A small amount of unemployment may reduce wage-push inflation (the Phillips curve)

Policies to Reduce Unemployment

Demand-Side Policies (for cyclical unemployment)

Fiscal policy:

• Increase government spending or cut taxes to boost AD
• Evaluation: multiplier effect amplifies impact; but time lags, crowding out, and national debt concerns limit effectiveness; risk of inflation if economy is near capacity

Monetary policy:

• Cut interest rates to reduce borrowing costs → increase C and I
• Quantitative easing (QE): central bank buys bonds → increases money supply → lowers long-term rates
• Evaluation: effective tool but limited at the zero lower bound; transmission mechanism may be weak if banks do not lend; QE may inflate asset prices more than real economic activity

Supply-Side Policies (for structural/frictional/NRU)

Policy	Target	Evaluation
Education and training	Skills mismatch	Long-term but slow; quality matters; may not match employer needs
Apprenticeships	Youth unemployment, skills gaps	Effective if well-designed; UK apprenticeship levy introduced 2017
Employment subsidies	Reduce cost of hiring	Direct but costly; may subsidise jobs that would exist anyway (deadweight)
Welfare reform	Increase work incentives	Universal Credit taper rate; but risks increasing poverty if benefits cut too far
Deregulation of labour markets	Reduce hiring costs	May increase flexibility but at cost of job security (gig economy concerns)
Regional policy	Geographical immobility	Enterprise zones, infrastructure investment; but expensive and slow
Improved job information	Frictional unemployment	Job centres, online platforms; low cost, effective
Reducing trade union power	Real wage unemployment	Thatcher's reforms in 1980s; controversial — weakens worker bargaining

The Phillips Curve and Unemployment

Short-run trade-off between inflation and unemployment:

• Reducing unemployment below the NRU via demand management → inflation accelerates
• Reducing inflation → unemployment rises (at least temporarily)
• Long-run: Phillips curve is vertical at NRU (Friedman/Phelps)
• Only supply-side policies can permanently reduce unemployment without inflation

Evaluation: Is Full Employment Achievable?

• Full employment does not mean zero unemployment — it means unemployment at the NRU (frictional + structural only)
• The UK target is typically an unemployment rate of ~4-5%
• Keynesian view: government can and should use demand management to keep unemployment low
• Classical/monetarist view: focus on supply-side policies; demand management only creates temporary reductions and long-run inflation
• Real-world: most governments use a combination of demand-side and supply-side policies
• Globalisation and technology continue to cause structural shifts, requiring continuous adaptation

Exam Technique

• Classify the type of unemployment before recommending policy — demand-side policies will not solve structural unemployment
• Use AD/AS and labour market diagrams to illustrate
• Discuss the Phillips curve trade-off and its limitations
• Evaluate policies by considering effectiveness, time lags, side effects, and political feasibility
• Reference UK data and examples (2008 recession, COVID-19 furlough scheme, regional disparities)
• In 25-mark essays, consider whether demand-side or supply-side policies are more effective — the answer usually depends on the type and cause of unemployment
