Free Trade
International exchange of goods and services without government-imposed barriers such as tariffs or quotas.
Advantages: Lower prices and wider product choice for consumers, lower input costs for firms, access to larger global markets for exporters, increased efficiency from foreign competition
Disadvantages: Foreign competition may force uncompetitive domestic firms to close, leading to job losses in declining industries, increased reliance on global supply chains
Explain one advantage and one disadvantage of free trade for consumers in a low-income country importing staple food crops.
- 1
- Advantage: Free trade allows global food suppliers to sell products at lower prices than small domestic farmers, reducing the cost of staple foods for low-income consumers and increasing their disposable income for other needs.
- 2
- Disadvantage: If cheap imported food undercuts domestic producers, many small farmers may go out of business, reducing long-term domestic food security and leading to price volatility if global supply chains are disrupted.
Exam tip:
Always link free trade points to specific stakeholders (consumers, workers, firms, government) to earn full marks for explanation and evaluation questions.
2. Trade Protection: Rationale and Policy Toolsβ β β βββ± 8 min

Protectionism
Government policies designed to restrict international trade and shield domestic industries from foreign competition.
Key reasons for protection: Prevent dumping of cheap foreign goods, protect employment in domestic industries, support new infant industries until they are competitive, generate tariff revenue for government, protect consumers from unsafe imported products, reduce current account deficits, retaliate against trade barriers imposed by other countries
Three core protection methods are tested in the exam:
Tariffs
Tax on imported goods that raises domestic prices, increases domestic output, reduces consumption and cuts imports. Pros: generates government revenue. Cons: raises prices for consumers, may lead to retaliation.
+ Pros: Generates government revenue; Easy to implement
β Cons: Raises prices for domestic consumers; May trigger retaliatory tariffs on exports
Quotas
Legal limit on the quantity of imports allowed, raises domestic prices and increases domestic output. Pros: guarantees import quantity is reduced. Cons: no government revenue, can lead to shortages.
+ Pros: Guarantees import volumes fall; Does not require price adjustments
β Cons: No revenue for government; Can lead to domestic supply shortages and price spikes
Subsidies
Government payment to domestic producers that shifts domestic supply right, increases domestic output and reduces imports. Pros: does not raise consumer prices. Cons: costs government money, may lead to inefficiency.
+ Pros: Does not raise consumer prices; Boosts competitiveness of domestic exporters
β Cons: Costs government tax revenue; Can encourage inefficiency in supported firms
Draw a fully labelled diagram to show the effect of a tariff on imported steel, and state the impact on domestic steel production and import volumes.
- 1
- Draw axes: vertical = Price (P), horizontal = Quantity (Q). Plot upward-sloping domestic supply (Sd) and downward-sloping domestic demand (Dd).
- 2
- Add a horizontal world price line (Pw) below the intersection of Sd and Dd. Label domestic production at Pw as Q1, domestic consumption as Q2, and imports as Q2 - Q1.
- 3
- Add a second horizontal line for Pw + t (world price plus tariff) above Pw. Label new domestic production as Q3 (higher than Q1), new consumption as Q4 (lower than Q2), and new imports as Q4 - Q3 (smaller than original imports).
- 4
- Conclusion: Domestic steel production increases, total imported steel volumes fall.
Exam tip:
You do not need to label consumer or producer surplus areas on protection diagrams; only the key price and quantity changes are required to earn full marks.
3. Trading Blocs and the Role of the WTOβ β β βββ± 6 min
β Calculator OK
Trading Bloc
A group of countries that agree to reduce or eliminate trade barriers between member states, often with common external tariffs for non-member countries. Accepted examples: EU, ASEAN, USMCA, MERCOSUR.
Impact on member countries: Access to larger free-trade markets, economies of scale for firms, lower consumer prices, but loss of independent trade policy
Impact on non-member countries: Face higher common external tariffs when exporting to the bloc, reduced access to member markets, risk of trade diversion away from non-member suppliers
World Trade Organization (WTO)
Global intergovernmental organization that regulates and facilitates international trade. Core actions: negotiate trade liberalization agreements, enforce global trade rules, mediate trade disputes between members, provide training and support for developing country traders.
Explain one positive and one negative impact of the EU trading bloc on a non-member African country that exports cocoa.
- 1
- Negative impact: The EU imposes common external tariffs on agricultural imports from non-members that do not have preferential trade agreements, making the African countryβs cocoa more expensive for EU buyers, reducing demand and export revenue for cocoa farmers.
- 2
- Positive impact: The EUβs Everything But Arms scheme gives tariff-free access to the EU market for goods from least developed countries, so qualifying African cocoa exporters can sell their products at lower prices than competitors, increasing export volumes and farmer incomes.
4. Global Trade Patternsβ β ββββ± 4 min

Trade patterns vary significantly between developed and developing countries:
- Developed countries: Typically export high-value manufactured goods (e.g., cars, electronics), services (finance, technology) and intellectual property, and import low-value raw materials, agricultural goods and labor-intensive manufactured products.
- Developing countries: Often export primary products (minerals, crops) and low-cost manufactured goods (e.g., clothing, toys), and import high-value technology, pharmaceuticals and specialized industrial equipment.
Explain one challenge a developing country that relies 80% on coffee exports may face in international trade.
- 1
- Global coffee prices are highly volatile, as they are affected by changes in weather conditions, harvest volumes and shifts in global consumer demand.
- 2
- If global coffee prices fall sharply, the countryβs total export revenue drops significantly, worsening its current account deficit and reducing government revenue from export taxes, limiting funding for public services like healthcare and education.
5. Common Pitfalls
Wrong move:
Drawing welfare loss triangles on tariff/quota diagrams
Why:
This is beyond the 4EC1 specification, and examiners will not award extra marks for it; you may waste time and risk mislabelling required elements.
Correct move:
Only label axes, domestic S/D curves, world price, post-protection price, domestic production/consumption levels and import quantities.
Wrong move:
Confusing quotas and subsidies
Why:
Quotas restrict the quantity of imports, while subsidies give financial support to domestic producers to reduce their costs, which are two distinct policy tools with different impacts.
Correct move:
Remember quotas are legal quantity limits on imports, while subsidies are cash payments to domestic firms.
Wrong move:
Claiming free trade only benefits developed countries
Why:
Free trade has clear benefits for developing countries, including access to larger export markets and cheaper input goods, as well as costs like harm to small domestic firms.
Correct move:
Always weigh both advantages and disadvantages for all country types when evaluating free trade.
Wrong move:
Listing vague WTO roles without specific examples
Why:
Examiners require specific, actionable functions of the WTO, not generic descriptions.
Correct move:
Reference specific WTO actions: mediating trade disputes, negotiating global tariff reductions, providing support for developing country traders.
Wrong move:
Stating tariffs only hurt foreign producers
Why:
Tariffs raise prices for domestic consumers, reduce product choice, and may lead to retaliatory tariffs on domestic exports, harming domestic firms as well.
Correct move:
Analyse the impact of tariffs on all stakeholders (consumers, domestic firms, foreign firms, government) when answering evaluation questions.
