What you'll learn

• What globalisation means and why economies have become more interconnected.
• The main drivers of globalisation, including trade liberalisation, transport, technology and multinational firms.
• How to evaluate the benefits and costs for consumers, firms, workers, governments and developing economies.
• How to build balanced exam judgements rather than simply saying “globalisation is good” or “globalisation is bad”.

1. The basic idea

Globalisation is about economies becoming more connected. A decision in one country can quickly affect consumers, firms and workers elsewhere. For example, a shipping disruption in Asia can raise costs for UK retailers; a US interest rate rise can affect capital flows into emerging economies.

Integration means economies are linked together more closely. Interdependence means countries increasingly rely on each other, so changes in one economy create effects in others.

2. The main drivers of globalisation

Falling transport and communication costs

Lower transport costs make it cheaper to move goods across borders. Container shipping, air freight and improved logistics have made global supply chains more practical.

Digital communication allows firms to coordinate production, customer service and finance across continents. A UK firm can design a product in London, outsource software support to India, assemble components in Vietnam and sell worldwide online.

Trade liberalisation

Trade liberalisation means reducing barriers to international trade. A tariff is a tax on imports. A quota is a physical limit on the quantity of imports. Reducing these barriers makes cross-border trade cheaper and easier.

Examples include World Trade Organization agreements, regional trade blocs, and bilateral trade deals. However, Brexit created new trade frictions between the UK and EU, such as rules-of-origin checks and customs paperwork.

Multinational corporations and FDI

A multinational corporation, or MNC, is a firm that operates in more than one country. Foreign direct investment, or FDI, occurs when a firm or investor from one country establishes a lasting ownership stake in production in another country, such as building a factory or buying a foreign firm.

MNCs often organise production through a global value chain, where different stages of production take place in different countries.

3. Measuring globalisation

One simple measure is trade openness, which compares the value of exports and imports with GDP. GDP, or gross domestic product, is the total value of goods and services produced in an economy over a period of time.

$$Trade\; openness=\frac{exports+imports}{GDP}\times 100$$

A higher percentage suggests the economy is more exposed to international trade.

4. Benefits of globalisation

Lower prices and greater consumer choice

Globalisation can reduce prices because firms can source cheaper inputs, use lower-cost production locations and benefit from larger markets. Consumers may gain access to a wider range of goods, such as electronics, clothing, food and online services.

This links to comparative advantage, the idea from David Ricardo that countries can gain from specialising in goods and services where they have the lowest opportunity cost. Opportunity cost means the value of the next best alternative foregone.

Higher output, growth and employment

Export opportunities can increase sales for firms. This may raise aggregate demand, employment and economic growth. For example, China’s rapid growth was strongly supported by manufacturing exports, while India has benefited from global demand for IT and business services.

For developing and emerging economies, globalisation can help reduce poverty if export-led growth creates jobs and raises real incomes. Vietnam is often used as an example of an economy that has attracted manufacturing FDI and expanded exports.

Economies of scale and innovation

Economies of scale occur when average costs fall as output increases. Selling to global markets allows firms to produce on a larger scale, potentially lowering unit costs.

Globalisation can also increase competition. Domestic firms may have to improve quality, cut costs and innovate to survive.

Technology transfer and skills

Technology transfer occurs when knowledge, production techniques or managerial methods spread between countries. MNCs may train local workers, introduce new machinery and improve supply-chain standards.

5. Costs of globalisation

Structural unemployment

Structural unemployment occurs when workers’ skills or locations do not match the jobs available in the economy. If UK manufacturing firms face lower-cost competition from abroad, some workers may lose jobs in declining industries.

This does not mean globalisation reduces total employment automatically. New jobs may be created in exporting sectors, logistics, finance, technology or services. The problem is that workers cannot always move easily between industries.

Inequality and pressure on wages

Globalisation can increase wage inequality. High-skilled workers may benefit from global demand, while low-skilled workers in richer economies may face competition from lower-wage countries.

In developing economies, export jobs may pay more than rural alternatives, but working conditions can be poor. The 2013 Rana Plaza disaster in Bangladesh highlighted concerns about safety standards in global clothing supply chains.

Environmental damage

More production and transport can increase carbon emissions, pollution and resource use. Some firms may locate production in countries with weaker environmental regulation. This is sometimes called the pollution haven hypothesis.

However, globalisation can also spread green technology, such as renewable energy equipment, so the environmental effect depends on regulation, energy sources and production methods.

Tax avoidance and loss of government control

MNCs may shift profits to low-tax countries, reducing tax revenue for governments. This can limit funding for public services. Governments may also feel pressure to keep corporation tax low to attract investment.

Globalisation can reduce national policy autonomy. For example, if a government raises business taxes sharply, highly mobile firms may threaten to relocate.

Supply-chain vulnerability

Long global supply chains can be efficient but fragile. COVID-19 disruptions, semiconductor shortages, Russia’s invasion of Ukraine, and Red Sea shipping risks all showed that global shocks can raise costs and delay production.

6. How to evaluate globalisation well

Evaluation means weighing up the strength of the benefits and costs, then making a reasoned judgement.

Short run versus long run

In the short run, globalisation can create disruption: job losses, firm closures and pressure on wages. In the long run, economies may gain from specialisation, innovation and productivity growth.

But the long-run gains are not automatic. They depend on education, retraining, infrastructure and support for workers and regions affected by change.

Developed versus developing economies

For developed economies such as the UK, globalisation may mean cheaper imports, strong service exports and access to global finance. But it can also contribute to deindustrialisation and regional inequality.

For developing economies, globalisation may bring FDI, jobs and export earnings. Yet it can also create dependence on a narrow range of exports, vulnerability to external shocks, and exploitation if labour and environmental standards are weak.

The role of government policy

Globalisation is more likely to raise living standards when governments manage it effectively. Useful policies may include:

• investment in education and retraining
• infrastructure improvements
• competition policy to prevent excessive MNC power
• environmental regulation
• labour protections
• international cooperation on tax avoidance

7. Overall judgement

Globalisation can increase efficiency, reduce prices, expand markets and support growth. It has contributed to major development gains in economies such as China, India and Vietnam.

However, it also creates losers as well as winners. Costs can include structural unemployment, inequality, supply-chain fragility, environmental damage and reduced policy autonomy.

The best judgement is usually conditional: globalisation is most beneficial where economies invest in skills, maintain strong regulation, support displaced workers and ensure that gains are widely shared.
