Globalisation is the increasing interdependence and integration of the world's economies, societies and cultures through cross-border trade, investment, migration and the spread of technology. It means that events in one part of the world increasingly affect people and businesses in other parts. Globalisation is not new, but it has accelerated dramatically since the 1980s due to several key drivers.
The main causes include: (1) Trade liberalisation — the reduction of tariffs, quotas and other trade barriers through organisations like the WTO and regional trade agreements, (2) Advances in technology — the internet, containerisation, and cheaper transport have reduced the cost of international trade and communication, (3) Deregulation of financial markets — allowing capital to flow more freely between countries, (4) Growth of multinational corporations (MNCs) — firms operating across borders, taking advantage of lower costs and new markets, (5) Political changes — the fall of communism opened up new markets, and (6) Migration — the movement of labour across borders in search of better opportunities.
For developed economies, globalisation brings: lower consumer prices through access to cheaper imports, greater product variety and choice, increased competition driving innovation and efficiency, access to larger export markets, and inward foreign direct investment (FDI) creating jobs. However, negative effects include: deindustrialisation as manufacturing moves to lower-cost countries, structural unemployment in declining industries, downward pressure on wages for unskilled workers, environmental concerns from increased production and transport, and cultural homogenisation.
For developing countries, potential benefits include: access to foreign capital and technology through FDI, job creation in export industries, technology transfer and skills development, higher economic growth rates, and integration into global supply chains. However, challenges include: exploitation of cheap labour and poor working conditions, environmental degradation, dependency on foreign firms that may relocate, growing inequality within countries, brain drain as skilled workers emigrate, and vulnerability to global economic shocks.
MNCs are firms that operate in more than one country. They are a key driver of globalisation. Benefits of MNCs to host countries include: job creation, tax revenue, technology transfer, infrastructure investment and improved productivity. Costs include: profit repatriation (profits sent back to the home country), transfer pricing to minimise tax payments, exploitation of weaker environmental and labour regulations, crowding out of local businesses, and political influence. The net impact depends on the regulatory framework of the host country.
For Edexcel IAL evaluation questions on globalisation, consider: it depends on the country's level of development, the strength of its institutions and regulations, the specific industries affected, the time frame (short-run disruption vs long-run gains), and the distribution of benefits (who gains and who loses). Stronger evaluation acknowledges that globalisation is not inherently good or bad — its effects depend on context, policy choices and whether the gains are redistributed. Use real-world examples (e.g. China's export-led growth, deindustrialisation in the UK Midlands) to support your arguments.
