International trade and the global economy exam tips
Topic Overview
International trade and the global economy explores how countries exchange goods, services, and capital across borders. This topic is central to understanding modern economics because no country is self-sufficient; trade allows nations to specialise in what they do best, leading to higher output and living standards. For OCR GCSE Economics, you'll examine the benefits and drawbacks of trade, the role of global institutions, and how trade affects different stakeholders.
The global economy refers to the interconnected network of economies worldwide, where events in one country can ripple across the globe. You'll study concepts like globalisation, trade liberalisation, and protectionism, as well as the balance of payments and exchange rates. Understanding these ideas helps you analyse real-world issues such as Brexit, trade wars, and the impact of multinational corporations on developing countries.
This topic builds on microeconomic principles like supply and demand, and extends them to an international scale. It also links to macroeconomic objectives such as economic growth and stability. By the end, you should be able to evaluate arguments for and against free trade, and discuss how governments and international bodies like the WTO manage global economic interactions.
Key Concepts
- →Specialisation and comparative advantage: Countries gain from trade by specialising in goods they produce at a lower opportunity cost, leading to mutual benefit.
- →Free trade vs protectionism: Free trade involves no barriers (tariffs, quotas), while protectionism uses these to shield domestic industries from foreign competition.
- →Balance of payments: A record of all transactions between a country and the rest of the world, including the current account (trade in goods/services) and financial account.
- →Exchange rates: The price of one currency in terms of another, affecting export/import prices and trade balances.
- →Globalisation: The increasing integration of economies through trade, investment, and technology, driven by reduced barriers and improved transport/communication.

Examiner Tips
- 💡Use real-world examples of trade agreements and current account data to support evaluation
- 💡Ensure diagrams for exchange rate determination are correctly labelled with supply and demand curves
- 💡When evaluating globalisation, always link back to the specific impact on sustainability (economic, social, environmental)
- 💡Practice calculating currency conversions accurately as these are common quantitative skill questions
- 💡Use real-world examples to illustrate points, such as the UK's trade with the EU post-Brexit or the US-China trade war. This shows application and can earn higher marks.
- 💡When evaluating, always consider both sides of an argument (e.g., free trade vs protectionism) and reach a justified conclusion. Use phrases like 'on one hand... on the other hand...'.
- 💡Define key terms precisely in your answers. For example, 'comparative advantage' must include 'lower opportunity cost' to get full marks.
Common Mistakes
- Confusing the balance of payments with the government budget
- Failing to distinguish between the effects of exchange rate changes on consumers versus producers
- Generalising the impacts of globalisation without considering the specific context of developed vs less developed countries
- Misinterpreting the difference between nominal and real values when discussing development indicators
- Misconception: Trade deficits are always bad. Correction: A trade deficit can indicate strong domestic demand and investment; it's not inherently harmful if financed by capital inflows.
- Misconception: Protectionism always protects jobs. Correction: While it may save some jobs in the short term, it can lead to higher prices for consumers, retaliation from other countries, and inefficiency in protected industries.
- Misconception: Comparative advantage means a country is better at producing everything. Correction: Comparative advantage is about relative efficiency; even if a country is worse at producing everything, it still benefits from specialising in what it's least bad at.
Frequently Asked Questions
What is the difference between absolute and comparative advantage?
Absolute advantage means a country can produce a good using fewer resources than another. Comparative advantage means a country can produce a good at a lower opportunity cost. Even if a country has absolute advantage in everything, both countries still benefit from trade if they specialise according to comparative advantage.
Why do governments impose tariffs and quotas?
Governments use tariffs (taxes on imports) and quotas (limits on quantity) to protect domestic industries from foreign competition, safeguard jobs, and reduce trade deficits. They may also use them to retaliate against unfair trade practices or to raise revenue. However, these measures can lead to higher prices for consumers and inefficiency.
How does a depreciation of the pound affect UK exports and imports?
A depreciation means the pound is worth less relative to other currencies. UK exports become cheaper for foreign buyers, so export volumes tend to rise. Imports become more expensive for UK consumers, so import volumes tend to fall. This can improve the trade balance but may also cause inflation if imported raw materials cost more.
What is the role of the World Trade Organization (WTO)?
The WTO is an international body that sets rules for global trade and resolves disputes between member countries. Its main goal is to promote free trade by reducing barriers like tariffs and quotas. It provides a forum for negotiations and ensures that trade flows as smoothly, predictably, and freely as possible.
Can free trade harm developing countries?
Yes, free trade can sometimes harm developing countries if they cannot compete with more advanced economies. Their infant industries may struggle to survive against established foreign firms, leading to job losses and deindustrialisation. However, free trade can also provide access to larger markets, technology transfer, and lower prices for consumers, so the net effect depends on the context.
What is globalisation and what drives it?
Globalisation is the increasing interconnectedness of economies through trade, investment, migration, and technology. Key drivers include reductions in trade barriers (e.g., WTO agreements), advances in transport and communication (e.g., container shipping, internet), and the rise of multinational corporations. It has led to greater specialisation and economic growth but also concerns about inequality and cultural homogenisation.
