What you'll learn
International Trade and Globalisation forms a substantial component of CIE IGCSE Economics Paper 2, examining why countries trade, the benefits and drawbacks of free trade, methods of protection, and the growth of multinational corporations. This topic regularly appears in 4-mark, 6-mark and 8-mark questions requiring analysis of trade patterns, evaluation of protectionist measures, and assessment of globalisation's impact on developing economies.
Key terms and definitions
Globalisation — the increasing integration and interdependence of world economies through trade, investment, migration, and the spread of technology and culture.
Absolute advantage — when a country can produce more of a good with the same resources than another country, or produce the same quantity using fewer resources.
Comparative advantage — when a country produces a good at a lower opportunity cost than another country, forming the basis for mutually beneficial trade.
Protectionism — government policies designed to restrict imports and protect domestic industries from foreign competition.
Tariff — a tax imposed on imported goods, raising their price and making domestic products relatively cheaper.
Quota — a physical limit on the quantity of a good that can be imported during a specific period.
Subsidy — a payment by government to domestic producers to lower their costs and make them more competitive against imports.
Multinational corporation (MNC) — a business that operates production or service facilities in more than one country.
Core concepts
Why countries trade
Countries engage in international trade because no nation can efficiently produce everything its population needs or wants. Trade allows countries to:
- Obtain goods and services they cannot produce domestically (e.g., Saudi Arabia importing food, UK importing bananas)
- Access products more cheaply than domestic production would allow
- Increase consumer choice and variety
- Achieve economies of scale by producing for larger markets
- Acquire resources, components, and technology unavailable domestically
Specialisation underpins modern trade patterns. When countries focus production on goods where they hold an advantage, global output increases and trading partners benefit through exchange.
Absolute and comparative advantage
Absolute advantage exists when one country requires fewer resources to produce a good than another. Bangladesh has absolute advantage in textile production compared to Switzerland because it can produce more garments with the same labour and capital inputs.
Comparative advantage provides the economic rationale for trade even when one country has absolute advantage in everything. A country has comparative advantage in producing the good with the lowest opportunity cost.
Worked numerical example:
| Country | Wheat (tonnes per worker) | Rice (tonnes per worker) |
|---|---|---|
| India | 4 | 8 |
| Pakistan | 2 | 3 |
India has absolute advantage in both products. However:
- India's opportunity cost of 1 tonne wheat = 2 tonnes rice foregone
- Pakistan's opportunity cost of 1 tonne wheat = 1.5 tonnes rice foregone
- Pakistan has comparative advantage in wheat (lower opportunity cost)
- India has comparative advantage in rice
By specialising—India in rice, Pakistan in wheat—and trading, both countries consume beyond their production possibility frontiers.
Benefits of free trade
Free trade (trade without government restrictions) generates multiple advantages:
For consumers:
- Lower prices through competition and efficient allocation
- Greater choice of products and brands
- Access to higher quality goods
For producers:
- Larger markets enabling economies of scale
- Access to cheaper raw materials and components
- Technology transfer and innovation diffusion
- Increased competition driving efficiency
For economies:
- More efficient resource allocation
- Higher economic growth from specialisation
- Employment in export industries
- Foreign exchange earnings
- Stronger international relations
Protectionism: methods and effects
Governments restrict trade despite efficiency arguments because of domestic political pressures and strategic considerations.
Tariffs raise import prices. A 25% tariff on Chinese steel entering the USA increases costs for American car manufacturers but protects Pennsylvania steel workers. Government collects tariff revenue while domestic producers gain market share.
Quotas physically limit imports. The EU historically used quotas on banana imports from Latin America, protecting former colonies in Africa and Caribbean. Quotas create scarcity, raising prices more than equivalent tariffs while generating no government revenue.
Subsidies lower domestic production costs. The EU's Common Agricultural Policy subsidises European farmers, allowing them to undercut imports. While protecting rural employment, subsidies cost taxpayers billions and encourage overproduction.
Other protectionist measures:
- Embargoes — complete bans on trade with specific countries (US embargo on Cuba)
- Regulations and standards — safety, health, or technical requirements that discriminate against imports
- Voluntary export restraints — exporting country agrees to limit sales
Arguments for and against protectionism
Arguments supporting protection:
- Infant industry protection — new industries need temporary shelter to develop economies of scale and expertise before competing internationally (e.g., South Korea protected its car industry in the 1970s)
- Sunset industry support — gradual decline prevents mass unemployment and regional devastation
- Strategic industries — national security requires domestic production capacity in defence, food, energy
- Anti-dumping — prevents foreign firms selling below cost to eliminate competition
- Protect employment — prevents job losses when cheap imports undercut domestic wages
- Prevent over-specialisation — reduces vulnerability to demand changes or supply disruptions
- Raise government revenue — tariffs generate income, especially important for developing countries with limited tax systems
Arguments against protection:
- Higher consumer prices — protection taxes consumers through inflated costs
- Inefficiency — removes competitive pressure, encouraging complacency and waste
- Retaliation — trading partners impose counter-measures, reducing exports (e.g., US-China trade war 2018-2020)
- Reduced choice — consumers access fewer products and lower quality
- Misallocation of resources — production occurs in high-cost locations
- Corruption — quota allocation and import licensing create opportunities for bribery
- Trade wars — escalating protection damages global growth
Globalisation: characteristics and causes
Globalisation manifests through:
- Increased international trade as proportion of GDP
- Growth of multinational corporations
- International capital flows and foreign direct investment
- Global supply chains spanning multiple countries
- Rapid technology and information transfer
- International migration for employment
- Cultural convergence through media and brands
Driving forces behind globalisation:
- Transport cost reduction — containerisation, larger ships, and aircraft make shipping cheaper. Moving goods from Shanghai to London now costs less per tonne than internal UK rail freight in 1950
- Communication technology — internet, fibre optics, and smartphones enable instant global coordination
- Trade liberalisation — WTO agreements, regional trade blocs, and bilateral deals reduce barriers
- Deregulation — governments remove capital controls and foreign investment restrictions
- Emerging economies — China, India, and others integrate into world markets
Multinational corporations
MNCs like Apple, Toyota, Unilever, and Nestlé operate globally, locating production where costs are lowest and selling worldwide.
Advantages for host countries:
- Employment creation — MNCs employ local workers, reducing unemployment (e.g., Nissan employing 7,000 in Sunderland, UK)
- Tax revenue — corporation tax, employee income tax, and business rates fund public services
- Technology transfer — modern production techniques and management practices spread to local firms
- Infrastructure development — MNCs build roads, ports, and utilities benefiting wider economy
- Export earnings — MNC production often targets export markets, earning foreign currency
- Training and skills — workers acquire expertise applicable throughout the economy
Disadvantages for host countries:
- Profit repatriation — earnings flow to shareholders abroad rather than circulating domestically
- Environmental damage — MNCs may exploit weaker regulations, causing pollution (e.g., oil extraction in Nigeria)
- Exploitation — low wages and poor conditions in factories supplying Western brands
- Dependency — economies reliant on few MNCs face devastation if firms relocate
- Competition — local businesses cannot compete with MNC resources and efficiency
- Tax avoidance — transfer pricing and offshore registration minimise tax payments
Trade blocs and economic integration
Countries form trade blocs to increase cooperation and reduce barriers between members while often maintaining protection against non-members.
Free trade area — members eliminate tariffs and quotas between themselves but maintain independent trade policies with outsiders (e.g., USMCA between USA, Mexico, Canada)
Customs union — free trade area plus common external tariff on imports from non-members (e.g., EU, MERCOSUR in South America)
Common market — customs union plus free movement of labour and capital between members
Monetary union — common market plus single currency and unified monetary policy (e.g., Eurozone)
Benefits of trade blocs:
- Trade creation — removing barriers increases member trade
- Market size — larger internal market attracts investment and enables economies of scale
- Bargaining power — negotiating as bloc increases leverage
- Political cooperation — economic integration reduces conflict
Costs of trade blocs:
- Trade diversion — switching from efficient non-member suppliers to less efficient members
- Loss of sovereignty — members cannot set independent trade policy
- Unequal distribution — benefits concentrate in wealthier regions
- Complexity — regulations and standards require harmonisation
Worked examples
Example 1: Comparative advantage calculation (6 marks)
Question: The table shows maximum daily production per worker in two countries:
| Country | Smartphones | Tablets |
|---|---|---|
| Malaysia | 6 | 3 |
| Indonesia | 4 | 3 |
(a) Which country has absolute advantage in smartphone production? [1] (b) Calculate the opportunity cost of producing 1 tablet in each country. [2] (c) Explain which country should specialise in tablet production. [3]
Answer:
(a) Malaysia has absolute advantage in smartphones because each worker produces 6 compared to Indonesia's 4 [1 mark]
(b) Malaysia: 1 tablet = 2 smartphones foregone (6÷3) [1 mark] Indonesia: 1 tablet = 1.33 smartphones foregone (4÷3) [1 mark]
(c) Indonesia should specialise in tablet production [1 mark] because it has comparative advantage—the opportunity cost of 1 tablet is only 1.33 smartphones compared to Malaysia's 2 smartphones [1 mark]. By specialising according to comparative advantage, both countries can trade and consume more than they could produce alone [1 mark].
Example 2: Protectionism evaluation (8 marks)
Question: Analyse whether a government should impose tariffs on imported steel.
Answer:
Tariffs on imported steel would protect domestic steel producers from foreign competition. This preserves employment in steel-producing regions, preventing unemployment and maintaining tax revenues from workers and firms. If the domestic steel industry is newly developing, temporary protection allows it to achieve economies of scale and become internationally competitive in future—the infant industry argument.
However, tariffs increase steel prices for domestic car manufacturers, construction companies, and other steel users, raising their costs and reducing international competitiveness. Consumers ultimately pay higher prices for cars, buildings, and appliances. The protected steel industry faces less pressure to improve efficiency, potentially remaining permanently uncompetitive. Trading partners may retaliate with tariffs on exports, harming industries where the country does hold comparative advantage.
Whether tariffs are justified depends on whether steel is genuinely an infant industry capable of becoming competitive, or whether protection merely delays inevitable adjustment. If major steel-using industries employ more workers than steel production, overall employment might fall despite protecting steelworkers. The government must weigh concentrated benefits to steel producers against dispersed costs to consumers and steel-using industries.
Example 3: MNC impact analysis (6 marks)
Question: Explain two advantages for a developing country when a multinational corporation opens a factory there.
Answer:
Employment creation: The MNC directly employs local workers in the factory, providing wages and reducing unemployment [1 mark]. Additionally, indirect employment is created in supplier firms and service businesses supporting the workers [1 mark]. For example, when Samsung built factories in Vietnam, hundreds of thousands gained employment [1 mark].
Technology transfer: The MNC introduces modern production techniques, machinery, and management practices [1 mark]. Local workers gain training and skills that can spread to domestic firms when workers change jobs [1 mark]. Vietnam's domestic electronics industry has grown as former Samsung employees established supplier businesses using acquired expertise [1 mark].
Common mistakes and how to avoid them
Confusing absolute and comparative advantage: Students state "Country A has comparative advantage because it produces more." Comparative advantage depends on opportunity cost ratios, not absolute quantities. Always calculate what is foregone to produce one unit, then compare ratios between countries.
Claiming tariffs reduce imports to zero: Writing "tariffs will stop all imports" is incorrect. Tariffs raise prices but imports continue unless prohibitively high. State that tariffs "reduce import quantity" or "make imports less competitive" rather than eliminating them.
Evaluating only one side: Protectionism questions require balanced analysis. Presenting only arguments for tariffs, or only arguments against, limits marks. Structure answers with "On one hand... However..." to demonstrate evaluative thinking that CIE mark schemes reward.
Vague MNC impacts: Stating "MNCs are good/bad for developing countries" without specific mechanisms earns minimal marks. Identify precise impacts—employment numbers, tax revenue, technology types, environmental damage specifics—with examples where possible.
Ignoring the command word: "Analyse" requires breaking down causes and consequences with chains of reasoning. "Evaluate" demands weighing up arguments and reaching a supported judgment. "Explain" needs detailed description of how/why something occurs. Match response structure to command word.
Forgetting trade-offs and opportunity cost: International trade is fundamentally about opportunity cost and specialisation. Answers that omit these concepts miss the analytical framework examiners expect. Explicitly reference what is foregone when discussing specialisation decisions.
Exam technique for International Trade and Globalisation
Command word recognition: "Define" questions (2 marks) require precise terminology without elaboration. "Explain" questions (4-6 marks) need detailed chains of reasoning showing how one thing leads to another. "Analyse" questions (6-8 marks) require breaking down into components and examining relationships. "Evaluate" or "Discuss" questions (8+ marks) demand arguments on multiple sides with a reasoned conclusion stating which argument is stronger and why.
Comparative advantage calculations: Show all working clearly. State the opportunity cost formula explicitly (what you give up ÷ what you gain). Write conclusions in full sentences—"Country X should specialise in Good Y because its opportunity cost of 2 units is lower than Country Z's opportunity cost of 3 units."
Protectionism questions structure: Paragraph 1—arguments supporting protection (infant industry, employment, strategic industries). Paragraph 2—arguments against protection (higher prices, inefficiency, retaliation). Paragraph 3—evaluation stating which arguments are stronger in the specific context given, considering timeframes, country development level, or industry characteristics.
Using examples effectively: Real-world examples (named countries, actual MNCs, specific trade agreements) demonstrate applied knowledge that mark schemes reward. However, examples alone do not constitute analysis—they must illustrate theoretical points. Structure: state the theoretical point, then add "For example..." to apply it.
Quick revision summary
International trade occurs because countries hold comparative advantages—producing goods at lower opportunity costs than others—enabling mutually beneficial specialisation and exchange. Free trade increases efficiency, choice, and growth but faces opposition through protectionism (tariffs, quotas, subsidies) protecting domestic industries and employment. Globalisation—driven by technology, transport improvements, and liberalisation—increases economic integration through trade, investment, and multinational corporations. MNCs bring employment, technology, and investment to host countries while potentially causing environmental damage, exploitation, and profit repatriation. Trade blocs eliminate internal barriers while potentially diverting trade from efficient non-members. Exam success requires calculating opportunity costs accurately, evaluating protectionism with balanced arguments, and analysing MNC impacts with specific mechanisms rather than vague assertions.
