Globalisation: Causes and Consequences

Globalisation refers to the increasing integration and interdependence of the world's economies through the growth of international trade, capital flows, migration, and the spread of technology and ideas. It is one of the defining economic trends of the past fifty years and has profound implications for growth, inequality, employment, and the environment. This lesson defines globalisation, explains its principal causes (trade liberalisation, technology, transnational corporations, containerisation), traces its consequences for consumers, workers, firms, governments and the environment, identifies the winners and losers, and evaluates whether globalisation has, on balance, raised welfare.

Spec Mapping

This lesson addresses AQA A-Level Economics (7136), section 4.2.6 — The international economy, specifically the sub-content on the causes and consequences of globalisation, the role of multinationals/transnational corporations (TNCs), and the impact of globalisation on individual countries, governments, producers, consumers, workers and the environment.

• Paper 2 (The national and international economy): globalisation appears in data-response chains (e.g., on FDI flows, trade growth, the US–China trade war) and in "evaluate the effects of globalisation" essays.
• Paper 3 (Economic principles and issues): globalisation is examined synoptically — linking to comparative advantage and the gains from trade, to TNCs and market structure, to the labour market and inequality, to economic development, and to the environment as a negative externality.

Assessment objectives in play:

• AO1 (Knowledge): define globalisation, FDI, a transnational corporation (TNC), trade liberalisation and containerisation.
• AO2 (Application): apply globalisation analysis to named contexts (China's opening, the elephant curve, global value chains, the US–China trade war).
• AO3 (Analysis): build chains from a cause (e.g., falling transport costs) through to a consequence (offshoring, lower prices, wage effects, emissions).
• AO4 (Evaluation): weigh the gains (growth, poverty reduction, lower prices) against the costs (within-country inequality, environmental damage, instability) and reach a supported judgement that distinguishes between groups, countries and time horizons.

Defining Globalisation

Key Definition: Globalisation is the process by which national economies become increasingly integrated and interdependent through the growth of international trade, investment, migration, and the sharing of technology, culture, and ideas.

Globalisation is not a single phenomenon but a multifaceted process encompassing:

• Economic globalisation — increased trade, FDI and financial flows, and the rise of cross-border production networks.
• Political globalisation — the growth of international organisations (WTO, IMF, World Bank, UN) that set rules for global economic governance.
• Cultural globalisation — the spread of consumer brands, media and cultural practices.
• Technological globalisation — global communication networks, the internet and digital platforms.

A useful way to organise the topic is as a chain running from causes through mechanisms to consequences — this structure also turns a descriptive answer into an analytical one.

Causes of Globalisation

1. Trade Liberalisation

• The GATT/WTO has overseen successive rounds of tariff reductions since 1947. Average tariffs have fallen from around 40% to below 5%, sharply lowering the cost of moving goods across borders.
• Regional trading blocs (EU, USMCA, ASEAN) have further reduced barriers, both tariff and non-tariff.
• Unilateral liberalisation by developing countries — China's "Open Door" policy from 1978 and India's liberalisation in 1991 — brought enormous populations into the global trading system. The economic mechanism is straightforward: lower barriers let countries specialise according to comparative advantage, raising trade volumes and integrating previously closed economies.

2. Technological Advances and Containerisation

Technology	Impact on globalisation
Containerisation (from the 1950s–60s)	Dramatically reduced shipping costs — a standardised steel container moves seamlessly between ship, rail and truck, slashing the cost and time of loading/unloading and making long-distance trade in low-value goods economic
Jet aircraft	Enabled rapid international travel and high-value freight transport
Internet and digital communication	Instant, near-costless communication across borders; enabled global supply chains, e-commerce and remotely delivered services
Fibre-optic cables and satellites	High-speed data transfer supporting global financial markets and coordinated cross-border production
Automation and AI	Reduced manufacturing costs and enabled the offshoring of routine service functions (call centres, back-office processing)

Containerisation deserves special emphasis: by collapsing the cost of moving physical goods, it is arguably the single most important technological driver of modern trade in manufactures, because it made it economic to fragment production across many countries.

3. Deregulation of Financial Markets

• Capital-account liberalisation has allowed money to flow freely across borders, financing cross-border investment.
• Financial deregulation in the 1980s (London's "Big Bang", 1986) opened global investment flows.
• The growth of international banking, stock markets and derivatives trading created genuinely global capital markets — which also transmit financial shocks rapidly across borders, as 2008 showed.

4. Transnational Corporations (TNCs / MNCs)

• TNCs drive globalisation by locating design, production, marketing and management across multiple countries, seeking lower costs, new markets and strategic resources.
• The classic illustration is a smartphone designed in California, with components sourced from several East Asian economies and final assembly in China — a single product embodying the comparative advantages of many countries via a global value chain.
• TNCs are both a cause of globalisation (they build the cross-border networks) and a channel through which its consequences — FDI, technology transfer, but also profit-shifting and bargaining power over governments — flow.

5. Political Changes

• The collapse of the Soviet Union (1991) and China's opening brought roughly a billion-plus workers into the global market economy, transforming the world labour supply.
• The spread of market-oriented policies (privatisation, deregulation, free trade) — sometimes labelled the "Washington Consensus" — reduced barriers to integration.
• The growth of rule-setting international institutions lowered the uncertainty and transaction costs of cross-border activity.

How the causes reinforce one another

The causes above are not independent; they compound. Cheaper transport (containerisation) and near-costless communication (the internet) made it technically feasible to slice production into a global value chain; trade liberalisation made it legally and commercially feasible by removing the tariffs that would otherwise tax goods each time a half-finished product crossed a border; financial deregulation made it financeable by letting capital flow to wherever production was cheapest; and TNCs were the organisations that actually assembled these cross-border networks. Remove any one link — say, re-impose high tariffs, as the US–China trade war partly did — and the whole structure becomes more costly and begins to fragment, which is exactly the "deglobalisation" pressure now visible. This interdependence is why globalisation accelerated so rapidly from the 1980s: several enabling forces arrived together and multiplied each other's effect. For the exam, recognising that the causes are mutually reinforcing (rather than a flat list) is itself an analytical point worth making.

Consequences of Globalisation

Winners from Globalisation

Group	How they benefit
Consumers in developed countries	Lower prices through access to cheaper imports; greater product variety
Workers in export sectors of developing countries	Employment opportunities and, over time, rising wages (e.g., Chinese manufacturing workers)
TNCs and their shareholders	Access to global markets; ability to locate production where costs are lowest
Developing countries that liberalised	Rapid growth and poverty reduction (China, India, Vietnam, Bangladesh)
Skilled and mobile workers	Can sell scarce skills in a global labour market at a premium

Losers from Globalisation

Group	How they are harmed
Low-skilled workers in developed countries	Job losses from offshoring and competition from low-wage imports; wage stagnation
Domestic firms unable to compete	Forced out by cheaper or larger foreign competitors
Workers in poor conditions	May face exploitation, low pay and unsafe conditions in some supply chains
The environment	More production, transport and consumption raise carbon emissions and degrade the environment
Countries with weak institutions	May face a "race to the bottom" in regulation and taxation

The crucial analytical insight is the Stolper-Samuelson logic from the trade lessons: opening to trade tends to raise the return to a country's abundant factor and lower the return to its scarce factor. In a capital- and skill-abundant advanced economy, the scarce factor is low-skilled labour — so even as the nation gains in aggregate, low-skilled workers can lose, which is exactly why globalisation produces concentrated losers alongside diffuse winners. This is the analytical bridge between "globalisation raises total welfare" and "globalisation increases inequality", and it is what an honest evaluation must reconcile.

Exam Tip: Globalisation questions frequently ask you to evaluate whether globalisation has been beneficial overall. The best answers distinguish between effects on different groups, countries and time horizons, and they use the Stolper-Samuelson mechanism to explain why the gains and losses fall where they do, rather than merely listing winners and losers.

Foreign Direct Investment (FDI) and TNCs

Key Definition: Foreign direct investment (FDI) is investment by a firm in one country into productive capacity (factories, offices, land) in another country, giving it a lasting management interest. It differs from portfolio investment, which is the purchase of financial assets without managerial control.

Benefits of FDI for host countries

• Capital inflow — raises the capital stock and productive capacity, helping to fill the savings gap (a direct link to the Harrod-Domar model in the barriers lesson).
• Job creation — directly and through supply chains.
• Technology and knowledge transfer — local workers and supplier firms absorb new techniques and management practices, a dynamic supply-side gain.
• Tax revenue — TNCs pay corporate taxes (though this is contested — see below).
• Improved infrastructure — TNCs may invest in transport, energy and communications that benefit the wider economy.

Costs of FDI for host countries

• Profit repatriation — TNCs may remit profits to the home country, worsening the host's current account (a negative entry in the primary income balance).
• Tax avoidance — transfer pricing and profit-shifting can erode the host's tax base, so the promised tax revenue partly fails to materialise.
• Exploitation — low wages, poor conditions and environmental damage in some operations.
• Crowding out — TNCs may outcompete nascent local firms, weakening domestic entrepreneurship.
• Dependency — over-reliance on a few large TNCs creates vulnerability if they relocate.
• Political influence — large TNCs can exert significant bargaining power over governments competing to attract them.

Transfer pricing and the "race to the bottom"

The tax-avoidance cost deserves spelling out because it is one of the sharpest contemporary criticisms of TNCs. Transfer pricing is the practice of setting the prices at which different parts of the same TNC trade with each other across borders. By manipulating these internal prices — for example, having a subsidiary in a high-tax country "buy" services or intellectual-property rights from a related subsidiary in a low-tax jurisdiction at inflated prices — a TNC can shift its accounting profits to wherever tax is lowest, even though the real economic activity took place elsewhere. The host country where the value was actually created then collects little corporation tax, undermining the "tax revenue" benefit that justifies courting FDI in the first place.

This connects to the wider fear of a "race to the bottom": because financial and physical capital is mobile while governments compete to attract it, each government faces pressure to cut corporate tax rates, weaken labour protections and relax environmental rules to avoid losing investment to rivals. If every government does so, the result can be a downward spiral in standards and tax revenues that leaves all of them worse off — a coordination failure across governments. The policy response has been growing international cooperation (for example, efforts to agree a global minimum corporate tax rate) precisely because no single country can solve the problem alone. For the exam, transfer pricing and the race to the bottom are high-value evaluation points showing that the distribution of globalisation's gains depends on the relative bargaining power of mobile TNCs versus territorially fixed governments.

Globalisation and Inequality

The effect of globalisation on inequality is complex and contested, and the single most important distinction is between inequality between countries and within them.

Between countries (international inequality):

• Globalisation has, on balance, reduced inequality between countries. China's rise has lifted hundreds of millions out of poverty, sharply reducing the global poverty rate. The World Bank has documented a large fall in the share of the world's population in extreme poverty since 1990 (from well over a third to under a tenth by the late 2010s).
• However, some countries — particularly parts of sub-Saharan Africa — have been largely bypassed and remain trapped in poverty, so convergence is uneven.

Within countries (domestic inequality):

• Globalisation has increased inequality within many countries, developed and developing alike.
• In the UK and US, wages for low-skilled workers stagnated while high-skilled workers and capital owners gained substantially — the Stolper-Samuelson logic in practice.
• Branko Milanovic's (2016) "elephant curve" captures this vividly: between roughly 1988 and 2008, the biggest income gains went to the emerging middle class of developing countries (especially China) and to the global top 1%, while the lower-middle income groups of developed countries (the "elephant's trunk") gained least — a powerful explanation for both falling between-country inequality and rising political discontent in rich-world labour markets.

The policy significance is that these two trends are not contradictory but two faces of the same process, and crucially they point to different remedies. Falling between-country inequality is something globalisation tends to deliver automatically through trade and FDI, so it requires little policy support beyond keeping markets open and ensuring poor countries can actually participate. Rising within-country inequality, by contrast, is a distributional by-product that markets will not self-correct, so it requires active policy — retraining and education to help displaced workers move into growing sectors, regional regeneration to address the geographic concentration of losses, and progressive taxation and transfers to redistribute some of the aggregate gains. A government that embraces openness (capturing the efficiency and poverty-reduction gains) without the accompanying redistribution will tend to produce exactly the pattern of concentrated rich-world losers that fuels the backlash — which is why economists frame the choice not as "globalisation versus protection" but as "globalisation with an active domestic policy versus globalisation without it".

Exam Tip: The distinction between inequality between countries (which globalisation has reduced) and within countries (which it has often increased) is a crucial analytical point. Cite Milanovic's elephant curve to evidence both at once — it is one of the highest-value applied references on this topic.

Globalisation, Deindustrialisation and the Environment

Globalisation has contributed to deindustrialisation in advanced economies — the falling share of manufacturing in GDP and employment. In the UK, manufacturing's share of GDP fell from around a third in the 1970s to roughly a tenth today, and former manufacturing regions (the North East, Midlands, South Wales) suffered job losses, depopulation and social strain. This concentrated regional harm fed into political discontent and is widely cited as a factor in the Brexit vote — a direct synoptic link to the EU/Brexit lesson. However, deindustrialisation is not solely caused by globalisation: automation and robotics have independently reduced the demand for manufacturing labour, so attributing the entire decline to trade is a common error.
