Globalisation & its dimensions

Globalisation is the growing interconnection and interdependence of the world's economies, societies and cultures, driven by flows of trade, capital, people and information. It has several dimensions:

• Economic — global trade, TNCs, foreign direct investment and integrated markets.
• Cultural — the spread of ideas, media, brands and lifestyles ("cultural globalisation").
• Political — the growing role of international organisations, agreements and governance.
• Environmental — shared, transboundary problems such as climate change and pollution.

Enablers: containerisation and cheaper transport, ICT and the internet, and trade liberalisation have all shrunk the friction of distance and accelerated globalisation.

Which dimension?

Global flows & interdependence

The global system is held together by flows that cross borders:

• Goods and services — the physical trade in commodities and traded services.
• Capital — investment, including foreign direct investment (FDI) by firms.
• Labour — migration of workers between countries.
• Information and ideas — data, technology and knowledge moving instantly.

These flows create interdependence: countries come to rely on one another, so a shock in one place (a factory closure, a shipping blockage) ripples through the whole system.

Interdependence cuts both ways: it can spread prosperity and stability, but it also transmits crises — the flip side of being deeply connected.

Name the flow

Comparative advantage & the division of labour

Why do countries trade rather than make everything themselves?

• Comparative advantage — a country should specialise in what it can produce at the lowest opportunity cost, then trade for the rest. Specialisation raises total output.
• International division of labour — different stages of production locate in different countries: research and high-value tasks in wealthier economies, labour-intensive assembly in lower-wage economies.

Some geographers criticise this pattern using core–periphery and dependency ideas: a powerful core dominates high-value activity while a periphery supplies raw materials and cheap labour, locking poorer countries into dependence.

Evaluate: comparative advantage predicts mutual gains from trade, but critics argue the gains are shared unequally and can entrench inequality between core and periphery.

Why specialise?

TNCs & global value chains

Transnational corporations (TNCs) organise production across many countries, creating global production networks and global value chains — the linked stages that add value from raw material to finished product. Key strategies:

• Offshoring — moving part of the firm's own production to another country (usually to cut costs).
• Outsourcing — contracting another company to carry out part of the work.
• Glocalisation — adapting a global product or brand to suit local tastes and markets.

Power & leakage: TNCs bring investment and jobs, but much value can be captured at the top of the chain, and profits may be repatriated ("leak") out of host economies.

Measuring trade

Global trade is uneven — a handful of economies dominate flows. Two key measures let us analyse a country's position:

Your turn — balance of trade

Your turn — trade as % of GDP

Trade blocs, the WTO & protectionism

Trade is shaped by rules and agreements:

• Trade blocs — groups of countries that reduce barriers between members, e.g. the EU, USMCA, ASEAN, Mercosur.
• The WTO (World Trade Organization) oversees global trade rules and works to lower barriers through agreements.
• Free trade removes barriers; protectionism raises them to shield home producers, using tariffs (taxes on imports), quotas (limits on quantity) and subsidies (support for domestic firms).

Trade-off: free trade can raise efficiency and choice; protectionism can defend jobs and infant industries but often raises prices and can trigger retaliation.

Fair trade & unequal power

The trading system distributes gains unevenly, and powerful players shape the rules:

• Fair trade and ethical trade schemes guarantee producers a fairer, more stable price and better conditions, aiming to spread the benefits of trade more evenly.
• Unequal power — wealthier economies and large TNCs can set terms, keep tariffs on processed goods, and capture most value, limiting development in poorer, commodity-dependent countries.

Analysts often track a country's export performance over time — for example, the percentage change in the value of its exports between two years.
