The meaning and importance of full employment

Full employment occurs when all individuals of working age, who are able and willing to work (excluding groups like students or retirees), can secure jobs at prevailing wage rates. This does not imply zero unemployment, as some people will always be transitioning between roles.

Why governments aim for full employment

Governments pursue full employment to boost overall production and improve living standards across the economy. When unemployment exists, the economy fails to utilise its resources fully, operating below capacity.

This situation can be illustrated on a production possibility frontier (PPF) diagram, where a point inside the curve (e.g., point A) represents underused resources. Achieving full employment shifts the economy to a point on the PPF curve (e.g., point B), indicating maximum output.

Under-employment

Under-employment happens when individuals hold jobs that do not fully use their skills, experience, or available time.

For example, a trained engineer working in a low-skilled role or someone seeking full-time work but only finding part-time employment would be under-employed. Like unemployment, under-employment prevents the economy from reaching full capacity, also shown as a point inside the PPF curve.

Types of unemployment including cyclical, seasonal, structural, frictional, and real wage

Unemployment can be categorised into several types, each with distinct causes and characteristics.

Cyclical unemployment

Cyclical unemployment, also known as demand-deficient unemployment, arises during economic downturns or recessions when aggregate demand drops. Labour demand is derived from consumer demand for goods and services, so low economic growth reduces job opportunities, leading to higher unemployment. Economies with a negative output gap often experience this type.

Seasonal unemployment

Seasonal unemployment stems from fluctuations in labour demand throughout the year in specific sectors. Industries like tourism, agriculture, or retail see peaks (e.g., summer for tourism or Christmas for shops) where more workers are needed, followed by quieter periods. This form is predictable, regular, and limited to certain industries, unlike cyclical unemployment which can impact any sector.

Structural unemployment

Structural unemployment results from long-term declines in particular industries or occupations, often due to shifts in consumer tastes, technological progress, or cheaper alternatives abroad. It is common in regions reliant on traditional sectors like manufacturing (e.g., steel or shipbuilding). This type is worsened by labour immobility, where workers cannot easily adapt or relocate.

Frictional unemployment

Frictional unemployment refers to the temporary joblessness experienced by individuals moving between jobs, such as after a contract ends or when seeking better pay. It exists even in economies at full employment, as some transitions are inevitable.

Real wage unemployment

Real wage unemployment occurs when wages exceed the equilibrium level where labour supply meets demand, creating excess labour supply. This is often driven by trade unions pushing for higher pay or the implementation of a national minimum wage (NMW) above the market rate.

On a labour market diagram, if the NMW is set above the equilibrium wage (W_e), labour supply rises to Q_s while demand falls to Q_d, resulting in unemployment from Q_d to Q_s. Increases in productivity or consumer spending can shift the demand curve right, mitigating this effect.

Factors affecting unemployment such as economic growth, labour immobility, and migration

Various elements influence unemployment levels, including broader economic conditions and workforce dynamics.

How economic growth affects unemployment

Economic growth impacts unemployment through derived demand for labour. Positive growth increases consumer demand, lowering unemployment as firms hire more workers. Conversely, negative growth or recessions raise unemployment by reducing demand for goods and services.

Labour immobility and structural unemployment

Labour immobility exacerbates structural unemployment by preventing workers from filling available jobs.

Types of labour immobility:

• Occupational immobility - Workers lack the skills needed for emerging roles as old occupations decline.
• Geographical immobility - Individuals cannot relocate from high-unemployment areas to regions with vacancies, often due to housing costs or family commitments.

Regions hit by structural issues may face a negative multiplier effect, where initial job losses reduce local spending, causing further unemployment.

Future trends increasing structural unemployment

Accelerating technological changes in products and processes will likely heighten structural unemployment by phasing out outdated industries and reducing labour needs. Better-informed consumers, via the internet and social media, may also shift spending patterns more rapidly, favouring cheaper or superior options.

Factors influencing frictional unemployment duration

The time spent between jobs depends on several elements:

• Economic conditions - Booms offer more vacancies, shortening frictional periods; slumps extend them due to job scarcity.
• Welfare benefits - Generous benefits may reduce urgency to find work or allow time for better opportunities, lengthening unemployment.
• Job information quality - Poor access to vacancy details or required skills prolongs job searches.
• Labour immobility - Both occupational and geographical barriers increase transition times.

Effects of migration on unemployment

Worker migration into a country boosts labour supply. In strong economies, this can raise national income, particularly if migrants bring complementary skills, with minimal impact on native unemployment. During recessions, however, high migration may temporarily increase unemployment among low-skilled native workers, though these effects often fade over time.

The costs and consequences of unemployment

Unemployment carries significant economic and social drawbacks, affecting individuals, businesses, and society.

Economic costs of unemployment

• Reduced incomes and spending - Unemployed individuals earn less, cutting their expenditure and potentially lowering firm profits.
• Government revenue and expenditure - Lower income tax and indirect tax from reduced consumption decrease government funds, while benefit payments rise.

Social consequences of unemployment

• Crime and health issues - High-unemployment areas may see increased crime, and financial stress can lead to health problems.
• Long-term employability - Prolonged unemployment eroding skills and training makes re-employment harder and perpetuates joblessness.

Most unemployment is involuntary, where people seek work but cannot find it, though some, like certain frictional cases, may be voluntary if individuals choose time off before starting new roles.
