Open a point below for its explanation and revision guidance.
a) Minimum wages in developing and developed countries
Minimum wage legislation establishes a legal floor below which hourly wages cannot fall, aiming to reduce poverty and inequality. In developed countries, a national minimum wage can increase living standards and incentivise workers to enter the labour market, though it may cause classical unemployment if set too high above the equilibrium. In developing countries, the impact is often complicated by a large informal sector where legislation is not enforced. Consequently, a minimum wage might only benefit a small formal workforce while pushing others into informal, unregulated jobs. The overall effect depends on the level of the minimum wage, the elasticity of labour demand, and the degree of monopsony power held by employers.
b) Skill shortages and their impact on international competitiveness
A skill shortage occurs when employers cannot find workers with the required qualifications to fill vacancies, restricting their ability to operate efficiently. This severely damages a country's international competitiveness. For example, if a UK firm cannot recruit enough software developers, it faces lower productivity, higher unit labour costs, and delayed product development compared to international rivals. Consequently, the firm's exports become less price and quality competitive in global markets. To mitigate this, firms might increase wages to attract scarce talent, which further drives up costs and reduces their international competitiveness, or they may be forced to relocate operations to countries with a stronger skills base.
c) Migration: o within economies o between economies
Migration involves the movement of workers seeking better employment. Migration within economies (internal migration) often occurs from rural to urban areas, such as workers moving to London for higher-paying jobs. This helps alleviate regional skill shortages but can cause housing congestion in cities and a brain drain in rural areas. Migration between economies (international migration) involves workers crossing borders, such as nurses moving from the Philippines to the UK. This increases the host country's labour supply, potentially depressing wages in low-skilled sectors but boosting overall productivity and filling critical skill gaps. Both forms of migration are vital for labour market flexibility and responding to macroeconomic shifts.
d) Inequality and incentives
Minimum wage legislation aims to reduce income inequality by raising the earnings of the lowest-paid workers. Its impact on incentives is complex. A higher minimum wage increases the incentive for inactive individuals to enter the labour market, as the opportunity cost of leisure rises. Conversely, it might reduce the incentive for workers to upskill if the wage differential between unskilled and semi-skilled roles narrows. For employers, a higher minimum wage creates an incentive to substitute capital for labour, such as using self-service checkouts. You must evaluate whether the reduction in inequality outweighs potential disincentives for employers to hire, which could worsen inequality if unemployment rises.

Marking Points
- Definition of a minimum wage as a legally enforced wage floor above the free-market equilibrium.
- Analysis of the benefits, such as poverty reduction, reduced inequality, and increased incentive to work.
- Explanation of potential drawbacks, including classical unemployment and increased business costs.
- Distinction between the impact in developed countries with formal enforcement and developing countries with large informal sectors.
- Evaluation of how monopsony employers might respond to a minimum wage by increasing employment.
- Define skill shortages as a situation where there is an insufficient supply of workers with the specific skills demanded by employers.
- Explain that skill shortages lead to lower labour productivity and higher unit labour costs.
- Analyse how higher unit labour costs force firms to increase export prices, reducing price competitiveness in international markets.
- Evaluate how a lack of skilled workers stifles innovation and product quality, reducing non-price competitiveness globally.
- Discuss potential business responses, such as raising wages to attract talent or relocating production to countries with abundant skilled labour.
- Identify internal migration as the movement of labour between regions within the same country, often driven by regional wage differentials.
- Identify international migration as the movement of labour across national borders, influenced by relative macroeconomic performance and immigration policies.
- Explain how inward migration increases the size of the active labour supply, shifting the labour supply curve outwards.
- Analyse the impact of migration on wages, noting that an influx of labour may depress wages in specific sectors while filling critical skill shortages in others.
- Evaluate the external costs and benefits of migration, such as increased pressure on public services versus higher tax revenues.
- Identification of how a minimum wage reduces income inequality by raising the wage floor.
- Explanation of how higher wages increase the incentive for individuals to supply labour.
- Analysis of how a compressed wage structure might reduce the incentive to gain new skills.
- Evaluation of employer incentives to substitute capital for labour or invest in training to offset higher wage costs.
- Assessment of the risk that higher minimum wages lead to unemployment, thereby exacerbating inequality.
Examiner Tips
- 💡Draw a clear diagram showing a minimum wage set above the equilibrium, highlighting the resulting excess supply of labour.
- 💡Always distinguish between the formal and informal sectors when discussing developing economies.
- 💡Evaluate the success of a minimum wage by considering its level relative to average earnings and the elasticity of demand for labour.
- 💡Use a specific industry example, such as IT or healthcare, to illustrate how skill shortages directly impact a firm's ability to compete internationally.
- 💡Link skill shortages explicitly to unit labour costs when explaining the transmission mechanism to reduced price competitiveness.
- 💡Consider the long-term versus short-term impacts; in the long run, firms might invest in automation to overcome a lack of skilled labour.
- 💡When analysing migration, distinguish clearly between the short-term impacts on local wages and the long-term impacts on aggregate supply and economic growth.
- 💡Use supply and demand diagrams for the labour market to illustrate how net inward migration shifts the labour supply curve to the right.
- 💡Consider the demographic characteristics of migrants, as they are often of working age and can help offset the economic challenges of an ageing population.
- 💡Use a labour market diagram to illustrate the potential unemployment effects of a minimum wage set above the equilibrium level.
- 💡Always link the concept of incentives to both employees (supply of labour) and employers (demand for labour).
- 💡When evaluating, consider the elasticity of demand for labour; inelastic demand means employment will fall less, making inequality reduction more likely.
Common Mistakes
- Stating that minimum wages always lead to job losses. Correction: Explain that in monopsonistic markets, a minimum wage can increase both wages and employment.
- Assuming minimum wage laws apply equally effectively everywhere. Correction: Highlight that in developing countries, a large informal economy often evades minimum wage legislation.
- Confusing minimum wage with the living wage. Correction: Define the minimum wage as a statutory legal requirement, whereas the living wage is often a voluntary benchmark based on the cost of living.
- Confusing a skill shortage with a general labour shortage. Correction: Specify that a skill shortage relates to a lack of specific qualifications or experience, not just a lack of available workers overall.
- Assuming skill shortages only affect price competitiveness. Correction: Explain that skill shortages also negatively impact non-price competitiveness by hindering innovation, quality, and customer service.
- Stating that skill shortages always lead to immediate business failure. Correction: Recognise that firms may adapt by investing in training, raising wages, or substituting capital for labour, though these increase costs.
- Assuming migration only refers to international movement. Correction: Recognise that migration also includes internal movement within an economy, such as rural-to-urban migration.
- Stating that inward migration always causes widespread unemployment among native workers. Correction: Explain that migrants also consume goods and services, creating new jobs and shifting labour demand outwards.
- Ignoring the impact of emigration (outward migration). Correction: Consider the effects of a 'brain drain' on the source country or region, which can suffer from reduced productive capacity.
- Assuming a minimum wage always reduces inequality. Correction: Acknowledge that if the minimum wage causes significant unemployment, inequality may actually increase as workers lose their incomes entirely.
- Stating that higher wages cause firms to substitute labour for capital. Correction: Firms will substitute capital for labour, replacing expensive workers with machinery or automation.
- Confusing the incentive to work with the incentive to upskill. Correction: Clearly distinguish between the incentive to enter the labour market (which increases) and the incentive to gain skills (which may decrease if wage differentials narrow).
