Globalisation — OCR A-Level Economics

Globalisation refers to the increasing interconnectedness and interdependence of economies worldwide, driven by the flow of goods, services, capital, labour, and technology across national borders. In OCR A-Level Economics, this topic explores how globalisation has accelerated since the late 20th century due to trade liberalisation, advancements in transport and communication, and the rise of multinational corporations (MNCs). You'll examine the causes, such as reduced trade barriers and global supply chains, and the consequences for growth, inequality, and environmental sustainability.

Understanding globalisation is crucial because it shapes modern economic policy and business strategy. It explains why your phone is assembled in China, designed in California, and sold globally. For your exam, you need to evaluate both the benefits—like lower prices for consumers, economies of scale for firms, and technology transfer to developing countries—and the drawbacks, including job losses in developed nations, tax avoidance by MNCs, and environmental degradation. This topic links directly to trade, development, and financial markets, making it a core part of the macroeconomics syllabus.

Globalisation fits into the wider subject by providing context for contemporary issues like Brexit, trade wars, and the COVID-19 pandemic's impact on supply chains. You'll use concepts such as comparative advantage, foreign direct investment (FDI), and exchange rates to analyse real-world events. Mastering this topic will help you critically assess policies like protectionism versus free trade, and understand the trade-offs between efficiency and equity in a globalised world.

• →Trade liberalisation: The reduction of tariffs, quotas, and non-tariff barriers, often through agreements like the WTO, which increases the volume and variety of goods traded globally.
• →Multinational corporations (MNCs): Large firms that operate in multiple countries, driving FDI, transferring technology, and influencing labour markets and tax revenues.
• →Global supply chains: The fragmentation of production across countries, where components are made in different locations to minimise costs, leading to increased trade in intermediate goods.
• →Foreign direct investment (FDI): Investment by a firm in one country into business interests in another, such as building factories or acquiring companies, which can boost host economies but also create dependency.
• →Economic convergence vs. divergence: The idea that globalisation may reduce income gaps between countries (convergence) as poorer nations catch up, or widen them (divergence) due to unequal benefits.

• Characteristics of monopolistic competition
• Short run equilibrium: supernormal profit or loss
• Long run equilibrium: normal profits
• Equilibrium price and output determination
• Advantages and disadvantages of monopolistic competition

• 💡Ensure diagrams clearly show the downward-sloping demand curve (AR) and marginal revenue (MR) curve, reflecting the firm's price-making power.
• 💡Distinguish clearly between the short-run position (where supernormal profit is possible) and the long-run position (where entry of new firms shifts the demand curve left until only normal profit remains).
• 💡Be prepared to evaluate the trade-off between the benefits of product variety and the lack of productive and allocative efficiency compared to perfect competition.
• 💡Use specific examples: In essays, refer to real-world cases like the rise of China as a manufacturing hub, the impact of NAFTA on US jobs, or the role of the WTO in trade disputes. This shows application and depth.
• 💡Evaluate both sides: For any globalisation issue, present arguments for and against, then reach a balanced conclusion. For instance, when discussing MNCs, mention benefits (jobs, technology) and costs (tax avoidance, labour exploitation). Use phrases like 'on the one hand... on the other hand'.
• 💡Link to economic theory: Connect globalisation to concepts like comparative advantage, economies of scale, and the J-curve effect. For example, explain how globalisation can improve allocative efficiency but may lead to market failure due to externalities like pollution.

• Misconception: Globalisation only benefits developed countries. Correction: While developed nations often gain from cheaper imports and investment opportunities, many developing countries have experienced rapid growth (e.g., China, India) through export-led strategies and FDI. However, benefits are unevenly distributed, and some regions may be left behind.
• Misconception: Globalisation always reduces inequality. Correction: Globalisation can increase inequality within countries, as skilled workers in tradable sectors gain while low-skilled workers face wage competition from abroad. The Kuznets curve suggests inequality may first rise then fall, but evidence is mixed.
• Misconception: Free trade is always beneficial. Correction: While free trade increases overall welfare through comparative advantage, it can cause structural unemployment and adjustment costs. Governments may need policies like retraining programmes to mitigate negative effects.
