What you'll learn
Globalisation represents one of the most significant economic trends of the past 50 years, reshaping how nations trade, produce goods and interact economically. This revision guide covers the key drivers of globalisation, its consequences for workers, businesses and governments, and why its impact differs between developed and developing economies. You'll learn to analyse these effects critically for both short-answer and extended-response IGCSE exam questions.
Key terms and definitions
Globalisation — the growing integration and interdependence of national economies through increased trade, investment, migration and flows of technology and ideas across borders
Multinational corporations (MNCs) — businesses that operate in more than one country, with production facilities, offices or sales operations located internationally
Foreign direct investment (FDI) — investment made by a firm or individual from one country into business interests located in another country, typically involving ownership of at least 10% of a company
Trade liberalisation — the removal or reduction of barriers to international trade, such as tariffs, quotas and regulations
Economic interdependence — a situation where countries rely on each other for goods, services, resources and markets, making their economies mutually dependent
Specialisation — when countries, firms or workers concentrate on producing a narrow range of goods or services in which they have a comparative advantage
Outsourcing — when a business contracts out part of its production process or service provision to another firm, often located in a different country where costs are lower
Protectionism — government policies designed to restrict international trade to protect domestic industries from foreign competition
Core concepts
Causes of globalisation
Globalisation has accelerated dramatically since the 1980s due to several interconnected factors that have made international economic integration both possible and profitable.
Improvements in transport technology
Container shipping revolutionised international trade by dramatically reducing costs and time. A standard container can move seamlessly between ships, trains and lorries without unpacking, cutting handling costs by up to 90%. Modern cargo aircraft enable rapid delivery of high-value, perishable or time-sensitive goods worldwide. Journey times between continents have fallen from months to hours for air freight, expanding the range of products that can be traded internationally.
Advances in communications and IT
The internet, email, video conferencing and mobile technology enable instant, low-cost communication across continents. Businesses can coordinate global supply chains in real-time, track shipments, manage international teams and serve customers worldwide. E-commerce platforms like Amazon and Alibaba connect producers directly with consumers across borders. Financial transactions can occur 24/7, enabling continuous global capital flows.
Trade liberalisation and removal of capital controls
Organisations like the World Trade Organization (WTO) have negotiated multilateral reductions in tariffs and trade barriers. Regional trade agreements—the European Single Market, USMCA (formerly NAFTA), CARICOM—have eliminated trade barriers between member states. Many governments have removed capital controls, allowing money to flow freely across borders for investment. China's integration into the global economy since the 1980s, and its WTO membership from 2001, brought 1.4 billion people into global markets.
Growth of multinational corporations
MNCs actively seek locations offering the most favourable combination of costs, skills, infrastructure and market access. They create integrated global supply chains, with different production stages in different countries. Nike designs shoes in the USA, sources materials from multiple countries, manufactures in Vietnam or Indonesia, and sells worldwide. This business model requires and reinforces globalisation.
Consequences of globalisation for developed economies
Developed economies—including the UK, USA, Germany, Japan—experience globalisation differently from developing nations, with both benefits and costs concentrated in specific sectors and regions.
Benefits for developed economies
Greater consumer choice is a direct consequence. UK supermarkets stock tropical fruits year-round, electronics from Asia, and clothing from around the world. Lower prices result from importing goods produced more cheaply abroad—clothing prices in the UK have fallen in real terms for decades. Access to larger markets enables UK firms like Rolls-Royce, GlaxoSmithKline and HSBC to expand beyond domestic limitations, achieving economies of scale and higher profits.
Increased competition drives innovation and efficiency. Domestic firms facing international rivals must improve quality, cut costs and innovate or lose market share. Foreign direct investment brings capital, technology and expertise—Japanese car manufacturers Toyota and Nissan have invested billions in UK production facilities, creating thousands of jobs.
Costs for developed economies
Structural unemployment occurs in industries unable to compete internationally. UK manufacturing employment fell from 6.8 million in 1979 to 2.6 million by 2020, as production shifted to lower-cost locations. Coal mining, steel production and shipbuilding sectors collapsed, devastating communities in Wales, Scotland and Northern England.
Wage pressure affects low-skilled workers whose jobs can be outsourced or face competition from imports produced by cheaper labour. Income inequality tends to increase—highly-skilled workers in finance, technology and professional services benefit greatly, while manufacturing workers see wage stagnation or job losses. Deindustrialisation creates regional inequality, with prosperous cities hosting service industries while former industrial regions decline.
Increased economic interdependence means financial crises spread rapidly—the 2008 crisis originating in US housing markets quickly became global, affecting UK unemployment and GDP growth.
Consequences of globalisation for developing economies
Developing economies—including Caribbean nations, India, Bangladesh, Vietnam—often experience globalisation as a rapid transformation with profound social and economic effects.
Benefits for developing economies
Foreign direct investment brings capital, technology, management expertise and employment. MNCs like Samsung, Volkswagen and Unilever have built factories across developing Asia, Africa and Latin America. Export-led growth has transformed countries like China, Vietnam and Bangladesh—China's GDP per capita increased from $156 in 1978 to over $10,000 by 2020.
Technology transfer occurs when MNCs introduce advanced production methods, training local workers and creating spillover effects as employees move to local firms or establish their own businesses. Access to developed country markets enables developing economies to specialise in labour-intensive manufacturing, exploiting their comparative advantage.
Rising incomes and employment reduce absolute poverty. Hundreds of millions in China, India and Southeast Asia have escaped extreme poverty through manufacturing and service sector jobs linked to global trade. Tax revenues from multinational operations and expanding domestic businesses fund improved infrastructure, education and healthcare.
Costs for developing economies
Exploitation concerns arise when MNCs pay low wages, maintain poor working conditions or ignore environmental regulations. The 2013 Rana Plaza factory collapse in Bangladesh, killing over 1,100 garment workers, highlighted safety issues in global supply chains. Environmental damage results from lax regulations—pollution, deforestation and resource depletion often accompany rapid industrialisation.
Overdependence on a narrow range of exports or foreign investors creates vulnerability. Caribbean tourism-dependent economies suffered severely during COVID-19 travel restrictions. Primary commodity exporters face volatile prices and terms of trade deterioration over time.
Inequality often increases within developing countries. Urban workers in export industries earn significantly more than rural agricultural workers, while skilled professionals benefit disproportionately. Brain drain occurs when educated workers migrate to developed economies seeking higher wages—Caribbean nations lose trained teachers, nurses and engineers.
Cultural homogenisation threatens local traditions, languages and practices as Western consumer culture spreads globally. Loss of sovereignty concerns emerge when MNCs influence government policy or international agreements constrain domestic policy options.
The role of multinational corporations
MNCs are the primary drivers and beneficiaries of globalisation, making strategic decisions about where to locate different business functions.
Why MNCs operate internationally
Lower production costs motivate outsourcing manufacturing to countries with cheaper labour, land or resources. Apple manufactures iPhones primarily in China and India, where wages are substantially below US levels. Access to raw materials drives mining and energy companies to invest wherever resources exist—Anglo American operates across Africa and South America.
Avoiding trade barriers through FDI allows MNCs to produce inside protected markets. Japanese car manufacturers built UK factories partly to access the European Single Market without tariffs. Market size attracts investment—companies seek locations with large populations or growing middle classes, explaining massive FDI flows into China and India.
Lower taxes influence headquarters location and profit reporting strategies. Ireland's low corporation tax has attracted Google, Apple and Microsoft European headquarters.
Impact of MNCs on host countries
Employment creation is often significant—individual MNC factories may employ thousands directly, with additional indirect jobs in supplier firms and local services. Skills development occurs through training programmes and technology transfer.
Tax revenue contributions fund public services, though profit repatriation reduces this benefit when MNCs transfer earnings back to home countries. Competition effects can harm local firms unable to match MNC efficiency, marketing budgets or economies of scale—small Caribbean manufacturers struggle against large multinationals.
Supply chain development creates opportunities for local businesses to supply components, services or materials to MNCs. Environmental and social impacts vary enormously depending on MNC practices and host government regulations.
Measuring globalisation's impact
Economists use several indicators to assess globalisation's extent and effects.
Trade openness measures exports plus imports as a percentage of GDP. Higher percentages indicate greater integration into global markets. The UK's trade openness exceeds 60%, while the USA's is around 25%.
FDI flows track investment crossing borders. Rising inward FDI suggests a country is attracting international business; high outward FDI indicates domestic firms are expanding internationally.
Employment structure changes show sectoral shifts—typically from agriculture to manufacturing to services—often accelerated by global integration.
Income distribution measures like the Gini coefficient track whether globalisation's benefits spread widely or concentrate among elites.
Development indicators—literacy rates, life expectancy, infant mortality—help assess whether globalisation delivers broad-based improvements in living standards.
Worked examples
Example 1: Explain two causes of globalisation [4 marks]
Model answer:
One cause is improvements in transport technology [1]. Container shipping and air freight have dramatically reduced the cost and time needed to move goods internationally, making global trade economically viable for a much wider range of products [1].
A second cause is trade liberalisation [1]. The World Trade Organization and regional trade agreements like the EU Single Market have reduced tariffs and quotas, removing barriers that previously restricted international trade [1].
Examiner guidance: Each cause needs clear identification (1 mark) plus development explaining how it promotes globalisation (1 mark). Avoid simply listing multiple causes without explanation.
Example 2: Analyse how globalisation might affect unemployment in a developed economy [6 marks]
Model answer:
Globalisation can increase structural unemployment in developed economies [1]. When firms outsource production to countries with lower labour costs, domestic manufacturing jobs are lost [1]. For example, UK textile manufacturing declined sharply as production shifted to Bangladesh and China, creating unemployment in former textile regions [1].
However, globalisation can reduce unemployment in some sectors [1]. Service industries like finance, consulting and creative industries expand by selling to global markets, creating highly-skilled jobs [1]. London's financial services sector employs hundreds of thousands, partly due to its global role [1].
Examiner guidance: "Analyse" requires examining positive AND negative effects with developed chains of reasoning. Use connectives like "because," "this leads to," "as a result" to build analysis chains. Real-world examples strengthen answers.
Example 3: Evaluate whether developing economies benefit from globalisation [8 marks]
Model answer:
Developing economies gain significant benefits from globalisation. Foreign direct investment brings capital, technology and employment that would otherwise be unavailable [1]. For example, Vietnam received over $20 billion in FDI in 2019, funding factories that employ millions in manufacturing [1]. Export-led growth enables developing economies to specialise in labour-intensive production where they have comparative advantage, raising incomes faster than domestic-focused strategies [1]. China's integration into global trade lifted hundreds of millions out of absolute poverty [1].
However, globalisation creates problems for developing economies. Workers may face exploitation through low wages, long hours and dangerous conditions, as the Rana Plaza disaster demonstrated [1]. Environmental damage often accompanies rapid industrialisation, with pollution and resource depletion creating long-term costs [1]. Overdependence on foreign investors or narrow export ranges makes economies vulnerable to external shocks [1].
Overall, developing economies generally benefit from globalisation, but outcomes depend heavily on government policies. Countries implementing effective regulation of working conditions and environmental standards, investing FDI-generated tax revenues in education and infrastructure, and diversifying their economies tend to experience sustained development [1]. Those failing to manage globalisation effectively may experience temporary growth followed by crisis.
Examiner guidance: "Evaluate" demands balanced judgment supported by evidence. Present both sides with developed analysis, then reach a reasoned conclusion. The best answers recognise that outcomes vary by context—avoid absolute statements like "globalisation is always good/bad."
Common mistakes and how to avoid them
Confusing globalisation with international trade alone. Globalisation includes trade but also capital flows, migration, technology transfer and cultural exchange. Define it comprehensively in extended answers.
Ignoring the distribution of costs and benefits. Globalisation's effects vary by sector, region, skill level and social class. Avoid statements like "workers benefit from globalisation"—specify which workers (e.g., "highly-skilled service sector workers benefit, while low-skilled manufacturing workers may face job losses").
Treating developed and developing economies identically. The question specifically distinguishes these categories because impacts differ systematically. Always address both types separately unless the question specifies otherwise.
Providing only theoretical points without examples. IGCSE mark schemes reward application to real-world contexts. Reference specific countries, companies, industries or events wherever possible.
Weak evaluation in 8-mark questions. Simply listing pros and cons isn't evaluation—you must weigh their relative importance, consider context, acknowledge that effects vary, or suggest conditions determining outcomes.
Confusing MNCs with general international trade. Not all international trade involves MNCs, and MNCs do more than trade—they invest, produce, employ and transfer technology across borders. Use the term precisely.
Exam technique for "Globalisation: causes, consequences and impact on developed and developing economies"
Command word awareness: "State/Identify" (1-2 marks) needs brief factual points. "Explain" (4-6 marks) requires developed reasoning showing why or how. "Analyse" (6-8 marks) demands chains of reasoning examining links and consequences. "Evaluate" or "Discuss" (8-10 marks) requires balanced arguments with reasoned judgment.
Structure 6-8 mark answers clearly: Start with your first main point, develop it with explanation/example, then clearly signal the contrasting point ("However..." or "On the other hand..."). This creates explicit balance that examiners can easily reward.
Use developed examples effectively: Rather than merely mentioning "China" or "MNCs," provide specific detail—"China's GDP per capita increased from $156 in 1978 to over $10,000 by 2020 following trade liberalisation." Specific data demonstrates knowledge depth.
Link to impacts throughout: When discussing causes, link to consequences; when discussing MNC behaviour, link to impacts on host countries. Cross-referencing between topics demonstrates sophisticated understanding that IGCSE mark schemes reward at the highest levels.
Quick revision summary
Globalisation—the integration of national economies through trade, investment and technology flows—results from improved transport and communications, trade liberalisation and MNC expansion. Developed economies gain consumer choice, lower prices and export opportunities but face structural unemployment and regional inequality. Developing economies benefit from FDI, technology transfer, employment and export-led growth but risk exploitation, environmental damage and overdependence. MNCs drive globalisation by seeking lower costs, new markets and resources. Impacts vary significantly by sector, skill level and government policy effectiveness. Successful exam answers require balanced analysis, real-world examples, and recognition that globalisation's effects differ between and within countries.
