Globalisation: causes, consequences and the role of multinational companies

What you'll learn

This revision guide covers globalisation as a key feature of the modern economy, examining why countries have become increasingly interconnected and what this means for producers, consumers, workers and governments. You'll learn how multinational companies drive and benefit from globalisation, and evaluate both the advantages and disadvantages of increased global integration for developed and developing economies.

Key terms and definitions

Globalisation — the increasing integration and interdependence of economies through cross-border trade, capital flows, labour migration and technology transfer.

Multinational company (MNC) — a business that operates in more than one country, with production or service facilities outside its country of origin (e.g. Unilever, Shell, Nestlé).

Foreign direct investment (FDI) — investment made by a firm or individual in one country into business interests located in another country, typically through establishing operations or acquiring assets.

Trade liberalisation — the removal or reduction of restrictions and barriers to the free exchange of goods and services between countries.

Protectionism — government policies designed to restrict international trade to protect domestic industries from foreign competition.

Tariff — a tax imposed on imported goods, making them more expensive than domestically-produced alternatives.

Quota — a physical limit on the quantity of a good that can be imported into a country during a specific time period.

Subsidy — a payment by government to domestic producers to lower their costs and make them more competitive against imports.

Core concepts

Causes of globalisation

Several interconnected factors have accelerated globalisation over recent decades:

Improvements in transport infrastructure

Containerisation has dramatically reduced shipping costs since the 1960s, making it economical to transport goods across continents
Larger cargo aircraft enable rapid international freight movement
Better road and rail networks facilitate supply chain integration
Lower transport costs mean firms can source materials globally and sell products in distant markets

Advances in communication technology

The internet enables instant communication between business operations worldwide
Video conferencing reduces need for expensive international travel
Digital file sharing allows design work in one country and manufacturing in another
Email and cloud computing coordinate global supply chains in real-time
Mobile technology connects workers and managers across time zones

Trade liberalisation and reduced barriers

World Trade Organization (WTO) negotiations have progressively lowered tariffs
Regional trade agreements (EU, USMCA, CARICOM) eliminate barriers between member states
Governments reduce quotas and other restrictions to encourage trade
Deregulation of financial markets allows capital to flow internationally

Growth of multinational companies

MNCs establish operations in multiple countries to access markets and resources
Foreign direct investment brings capital, technology and management expertise across borders
Global brands (Apple, Samsung, McDonald's) create standardised products for worldwide markets
Mergers and acquisitions create larger firms with international reach

Consequences of globalisation for producers

Benefits for producers:

Larger markets — firms can sell to billions of consumers globally rather than just domestic customers, increasing potential revenue and enabling economies of scale
Lower production costs — businesses can locate manufacturing where labour, land or raw materials are cheapest (e.g. textile firms moving production from UK to Bangladesh)
Access to resources — companies source materials globally, finding best quality or lowest prices (e.g. Caribbean manufacturers importing components from Asia)
Increased specialisation — countries focus on products where they have comparative advantage, improving efficiency

Challenges for producers:

Increased competition — domestic firms face competition from efficient foreign producers, potentially losing market share
Need for innovation — constant pressure to improve products and processes to remain competitive globally
Supply chain vulnerability — dependence on international suppliers creates risk from transport disruptions or political instability
Quality control difficulties — coordinating standards across multiple countries requires sophisticated management

Consequences of globalisation for consumers

Benefits for consumers:

Lower prices — international competition and production in low-cost countries reduce prices (e.g. cheap electronics from China)
Greater choice — access to products from worldwide, not just domestic producers (e.g. tropical fruit in UK supermarkets year-round)
Higher quality — competition drives innovation and quality improvements
Access to global services — internet enables purchasing from international retailers and using foreign service providers

Drawbacks for consumers:

Job insecurity — workers may lose employment when firms relocate abroad, reducing household incomes
Reduced product variety in some sectors — global brands can dominate, reducing local alternatives
Cultural homogenisation — local products and traditions may disappear as global brands spread

Consequences of globalisation for workers

Potential benefits:

Employment opportunities — MNCs create jobs in developing countries through FDI
Higher wages — foreign firms often pay above local rates to attract skilled workers
Skills transfer — workers learn new techniques and technologies from international companies
Migration opportunities — workers can seek employment in countries with labour shortages

Potential drawbacks:

Job losses — domestic firms closing due to foreign competition leads to unemployment, particularly in manufacturing sectors in developed countries
Wage pressure — workers in developed countries face downward pressure on wages as firms threaten relocation
Exploitation concerns — some MNCs pay low wages and maintain poor conditions in developing countries
Job insecurity — MNCs can relocate quickly, leaving workers unemployed

Consequences of globalisation for governments

Benefits for governments:

Tax revenue — MNCs contribute corporate taxes and employees pay income tax
Foreign exchange earnings — exports to international markets bring foreign currency
Technology transfer — FDI brings advanced production methods and management practices
Infrastructure investment — MNCs may build roads, ports and utilities benefiting the wider economy

Challenges for governments:

Tax avoidance — MNCs use transfer pricing and locate headquarters in low-tax countries, reducing government revenue
Reduced policy autonomy — international competition limits ability to raise taxes or implement regulations
Environmental concerns — pressure to attract FDI may lead governments to lower environmental standards
Unemployment costs — structural unemployment from factory closures requires welfare spending and retraining programmes
Inequality — globalisation may benefit skilled workers and capital owners more than unskilled workers

The role and impact of multinational companies

Why MNCs operate internationally:

Access new markets with large consumer bases
Reduce costs by locating production where factors of production are cheaper
Avoid trade barriers by producing inside target markets
Secure supplies of raw materials in resource-rich countries
Benefit from government incentives (tax breaks, subsidies, infrastructure)

Advantages of MNCs for host countries:

Employment creation — MNCs employ local workers, reducing unemployment and increasing household incomes
Capital investment — FDI provides funds that may not be available domestically, increasing productive capacity
Technology and skills transfer — local workers and firms learn advanced techniques, raising productivity
Export opportunities — MNC subsidiaries often export, earning foreign currency
Tax revenue — corporate taxes and employee income taxes fund government spending
Supply chain development — local firms become suppliers to MNCs, creating additional employment and income
Infrastructure improvements — MNCs may fund roads, ports and telecommunications benefiting the wider economy

Disadvantages of MNCs for host countries:

Profit repatriation — profits flow back to MNC headquarters abroad rather than being reinvested locally
Exploitation of workers — MNCs may pay low wages and maintain poor working conditions to minimise costs
Environmental damage — lax regulation in developing countries may allow pollution and resource depletion
Dominance of local markets — MNCs with superior resources may force smaller domestic firms out of business
Economic dependence — over-reliance on one or few MNCs creates vulnerability if they relocate
Tax avoidance — transfer pricing and profit-shifting reduce tax revenue for host governments
Cultural impact — global brands may undermine local culture and traditions

Worked examples

Example 1: Analysis question (6 marks)

Question: Analyse how improvements in technology have contributed to globalisation.

Mark scheme approach:

Two developed analytical points (3 marks each):

Point 1: Communication technology has enabled real-time coordination of global operations. The internet and mobile technology allow businesses to manage supply chains across multiple countries simultaneously. For example, a UK fashion retailer can design products in London, manufacture in Bangladesh, and receive instant updates on production progress. This reduces costs and delays, making international operations viable, which increases global trade and investment.

Point 2: Transport technology has dramatically reduced the cost of moving goods internationally. Containerisation allows standardised loading and unloading, reducing time in ports and damage to goods. Larger container ships benefit from economies of scale, lowering per-unit shipping costs. This makes it economical for firms to source components from the cheapest suppliers worldwide rather than locally, increasing international trade flows and the integration of economies.

Example 2: Evaluation question (8 marks)

Question: Discuss whether developing countries benefit from the operations of multinational companies.

Mark scheme approach:

Arguments they benefit (4 marks):

MNCs create significant employment in developing countries, providing jobs that often pay above local average wages. For example, a car manufacturer opening a plant may employ thousands directly and create additional jobs in the supply chain. This reduces unemployment and raises household incomes, increasing living standards.

MNCs also bring technology and skills that would otherwise be unavailable. Workers learn modern production techniques and management practices, raising productivity. These skills spread to the wider economy when workers move to local firms, creating long-term benefits beyond the MNC's direct operations.

Arguments they may not benefit (4 marks):

However, MNCs repatriate most profits to their home country headquarters rather than reinvesting locally. This means developing countries lose potential funds for domestic investment. The initial capital injection is beneficial, but ongoing profit outflows may exceed the original investment over time.

Furthermore, MNCs may exploit weak environmental regulations in developing countries, causing pollution and resource depletion. Short-term employment gains must be weighed against long-term environmental damage that reduces living standards. Mining companies, for instance, may leave areas degraded after extracting resources.

Evaluation (judgment):

The net benefit depends on government policies. If regulations ensure fair wages, working conditions and environmental protection while tax systems capture appropriate revenue, MNCs likely benefit developing countries. Without such policies, exploitation may outweigh employment and investment benefits.

Example 3: Definition and explanation (4 marks)

Question: Define globalisation and explain one reason why it has increased.

Answer:

Globalisation is the increasing integration and interdependence of economies through cross-border trade, capital flows and technology transfer (2 marks for definition).

One reason for increased globalisation is trade liberalisation. The World Trade Organization has negotiated reductions in tariffs between member countries, making imports cheaper. This encourages firms to export to international markets as foreign goods face lower taxes, increasing the volume of international trade and connecting economies more closely (2 marks for explained reason with example).

Common mistakes and how to avoid them

Confusing globalisation with trade — Globalisation encompasses trade, investment, migration and technology transfer, not just exports and imports. Always consider multiple dimensions when discussing globalisation.
Stating MNCs are always harmful or always beneficial — Avoid one-sided arguments. The impact depends on circumstances, government policies and specific industries. Evaluation questions require balanced analysis showing both advantages and disadvantages.
Forgetting to distinguish between countries — The consequences differ for developed and developing countries. Workers in UK manufacturing may lose jobs while workers in Bangladesh gain employment from the same globalisation process.
Mixing up tariffs, quotas and subsidies — A tariff is a tax on imports; a quota is a quantity limit; a subsidy is a payment to domestic producers. Use precise terminology to demonstrate economic understanding.
Assuming all large companies are MNCs — An MNC must have production facilities or operations in multiple countries, not just export to other countries. Tesco operating stores in several countries is an MNC; a small UK firm that exports is not.
Ignoring the evaluation in 'Discuss' or 'To what extent' questions — These command words require judgment. After presenting both sides, conclude with reasoned evaluation considering which factors are most significant or under what circumstances one argument prevails.

Exam technique for "Globalisation: causes, consequences and the role of multinational companies"

'Define' questions (2 marks) — Provide a clear, concise definition using precise economic terminology. For globalisation, mention integration/interdependence of economies and at least two of: trade, investment, migration, technology.
'Analyse' questions (6 marks) — Develop two chains of reasoning, each showing cause and effect. Use connective phrases: "This leads to...", "As a result...", "Therefore...". Include real-world examples to support analytical points. Each chain should have at least three linked stages.
'Discuss' or 'Evaluate' questions (8+ marks) — Present balanced arguments for and against, using separate paragraphs. Include specific examples and develop each argument fully. Crucially, add evaluation showing judgment: which argument is stronger, under what circumstances, what factors determine the outcome. Evaluation earns the highest marks.
Use specific examples — Reference actual countries, companies or industries where relevant (Bangladesh garments, Caribbean CARICOM, UK automotive industry). This demonstrates applied knowledge beyond generic understanding.

Quick revision summary

Globalisation—the increasing integration of world economies—results from improved transport and communication technology, trade liberalisation and MNC growth. For consumers, benefits include lower prices and greater choice; producers gain access to larger markets but face increased competition. Workers may gain employment opportunities but face job insecurity. MNCs bring investment, employment and technology to host countries but may repatriate profits and exploit weak regulations. The net impact depends on government policies and circumstances. Understand both advantages and disadvantages for different economic agents, and be prepared to evaluate which factors dominate in specific contexts.
