Trade and development — Eduqas A-Level Economics

Trade and development explores the relationship between international trade and economic development, particularly for low-income countries (LICs). This topic is central to WJEC A-Level Economics as it examines how trade policies, globalisation, and terms of trade affect growth, poverty reduction, and structural change. Students analyse theories such as comparative advantage, the Prebisch-Singer hypothesis, and the role of the World Trade Organization (WTO) in shaping trade rules.

Understanding trade and development is crucial because it explains why some nations remain trapped in primary commodity dependence while others diversify into manufacturing and services. The topic also evaluates strategies like import substitution industrialisation (ISI) versus export-oriented growth, and the impact of trade liberalisation on inequality and environmental sustainability. It connects to broader themes of globalisation, economic integration, and the Sustainable Development Goals (SDGs).

For WJEC, students must apply these concepts to real-world case studies, such as the rapid growth of East Asian economies (e.g., South Korea) versus the struggles of sub-Saharan African countries. They should be able to critically assess policies like fair trade, aid for trade, and regional trade agreements (e.g., African Continental Free Trade Area). Mastery of this topic enables students to evaluate the extent to which trade can be a driver of inclusive development.

• →Terms of trade: The ratio of export prices to import prices; a deterioration (fall) can harm LICs reliant on primary commodities, as per the Prebisch-Singer hypothesis.
• →Comparative advantage: The ability to produce a good at a lower opportunity cost; specialisation can boost efficiency but may trap countries in low-value sectors.
• →Trade liberalisation: Reducing tariffs and quotas; can increase competition and efficiency but may harm infant industries and worsen inequality.
• →Import substitution industrialisation (ISI): A strategy of protecting domestic industries via tariffs to reduce reliance on imports; often criticised for inefficiency and lack of competitiveness.
• →Export-oriented growth: Focusing on exporting manufactured goods; successful examples include the 'Asian Tigers' (Hong Kong, Singapore, South Korea, Taiwan).

• Explanation of absolute versus comparative advantage
• Use of numerical and graphical approaches to illustrate comparative advantage
• Calculation and interpretation of the terms of trade
• Analysis of protectionist methods including tariffs, quotas, subsidies, exchange rate manipulation, and administrative policies
• Evaluation of the costs and benefits of globalisation
• Identification of the UK's major export sectors
• Understanding the role of the WTO in policing trade agreements

• 💡Ensure you can perform numerical calculations for comparative advantage and terms of trade
• 💡Always use diagrams to support your analysis of protectionist policies like tariffs
• 💡When evaluating globalisation, consider both the positive and negative impacts on different economic agents
• 💡Be prepared to discuss the role of the WTO in the context of contemporary trade disputes or agreements
• 💡Use specific examples: When discussing trade policies, refer to real countries (e.g., South Korea's export-led growth, Ghana's cocoa dependence). This shows application and depth.
• 💡Evaluate critically: Don't just describe theories; assess their limitations. For instance, comparative advantage assumes perfect mobility of resources, which is unrealistic in LICs.
• 💡Link to development indicators: Connect trade outcomes to GDP per capita, HDI, poverty rates, and inequality. This demonstrates understanding of development beyond just income.

• Confusing absolute advantage with comparative advantage
• Failing to use diagrams when explaining the impact of tariffs
• Neglecting to evaluate the impact of globalisation on different stakeholders (households, firms, government)
• Misinterpreting the terms of trade index
• Misconception: Free trade always benefits all countries equally. Correction: While trade can increase overall output, gains are unevenly distributed; LICs may face declining terms of trade, job losses in vulnerable sectors, and increased inequality.
• Misconception: Comparative advantage is static. Correction: Comparative advantage can change over time through investment in education, infrastructure, and technology; countries can 'move up the value chain'.
• Misconception: Trade deficits are always bad. Correction: A trade deficit can be financed by capital inflows (e.g., foreign investment) and may reflect strong domestic demand; it is not inherently harmful if used for productive investment.
