What this dot point is asking
NESA wants you to define globalisation and describe the main flows that connect national economies: trade in goods and services, financial flows, foreign investment by transnational corporations, technology, and the international labour market. You should be able to quote gross world product, the share of trade in world output, and the role of TNCs and the international business cycle in transmitting shocks. Expect a 4 to 8 mark short answer in Section II.
The answer
Globalisation defined
Globalisation is the process of increasing economic integration between countries through the flow of goods and services, capital (financial and physical), labour, technology and ideas across national borders.
The four engines of globalisation are:
- Lower transport costs. Containerisation since the 1960s, larger ships and air-freight networks have collapsed the cost of moving goods.
- Lower communication costs. Submarine fibre, satellite networks and the internet have made instantaneous coordination of supply chains essentially free.
- Trade liberalisation. Eight rounds of GATT and WTO agreements, plus regional free trade agreements (NAFTA, EU single market, RCEP), have cut average tariffs on manufactures from roughly 40 percent in 1947 to under 5 percent by 2020 (WTO).
- Financial deregulation. Removal of capital controls since the 1980s has integrated global capital markets.
Gross world product (GWP)
Gross world product is the sum of all final goods and services produced by national economies. It is around USD 105 trillion in 2025 (IMF World Economic Outlook). World real GDP growth has averaged around 3.0 to 3.5 percent per year over the last decade, with major slowdowns during the 2008 GFC and the 2020 COVID-19 recession.
Trade in goods and services
Merchandise and services exports together amount to roughly 28 percent of gross world product (World Bank, World Development Indicators). Trade has grown faster than output for most of the post-war period, although the trade-to-GWP ratio has been roughly flat since the GFC ("slowbalisation").
The composition of world trade has shifted:
- Manufactures dominate world trade by value (about 70 percent of merchandise exports).
- Services are the fastest-growing component, especially digital services, financial services and tourism.
- Primary commodities (energy, minerals, agriculture) account for around a quarter of merchandise trade.
Financial flows
Cross-border financial flows include foreign direct investment (FDI), portfolio investment (shares, bonds) and short-term capital. Global FDI flows total around USD 1.5 trillion per year (UNCTAD), of which roughly two-thirds is intermediated by transnational corporations.
The growth of global finance has outpaced trade since the 1980s. Daily turnover in the global foreign exchange market exceeded USD 7.5 trillion in 2022 (BIS Triennial Survey).
Investment and transnational corporations
A transnational corporation (TNC) is a firm with operations in two or more countries. TNCs account for around 80 percent of world trade through global value chains (GVCs), in which intermediate goods cross borders multiple times. The 100 largest TNCs by foreign assets are mostly headquartered in advanced economies but earn an increasing share of revenue from emerging markets.
Technology, transport and communication
The technological dimension of globalisation has accelerated since 2010. Cloud computing, mobile broadband, AI tools and digital platforms have allowed services that were previously non-tradable (legal advice, accounting, software engineering) to be delivered remotely. Australia's IT services exports have grown 12 percent per year on average over the last decade (ABS).
The international business cycle
The international business cycle is the synchronised pattern of economic expansions and recessions across countries. Synchronisation has tightened since the 1990s due to:
- Trade linkages. Australia's exports to China rise and fall with Chinese GDP growth.
- Financial linkages. Equity markets in New York, London and Sydney move together in response to global shocks.
- Confidence linkages. Consumer and business sentiment is influenced by international news.
The 2008 GFC and the 2020 COVID-19 recession were textbook examples of synchronised global downturns. Regional business cycles also exist (the euro area, East Asia), and Australia is closely tied to the East Asian cycle through its commodity exports to China, Japan and South Korea.
Diagrams to draw from memory
- The circular flow with the international sector. Households, firms, government, financial sector and the overseas sector (exports as injections, imports as leakages).
- A line graph of world trade share of GWP over time. Trade share rising steeply 1990 to 2008, flat 2008 to 2024.
Common HSC traps
- Confusing globalisation with free trade
- Globalisation is broader, including capital, labour, technology and ideas. Free trade is one driver of globalisation.
- Treating TNCs as inherently good or bad
- Markers reward balanced analysis: TNCs raise productivity and bring FDI, but can also avoid tax, weaken local competition and shift labour standards.
- Quoting only old GWP or trade figures
- Update your data card each term. Use the most recent IMF World Economic Outlook and WTO data.
Past exam questions, worked
Real questions from past NESA papers on this dot point, with our answer explainer.
2022 HSC6 marksExplain how globalisation has impacted economic growth and development in the global economy.Show worked answer →
A 6 mark response needs a definition of globalisation, three or four specific impacts, and explicit links to growth and development.
- Define globalisation
- The process of increasing integration of national economies through the flow of goods and services, capital, labour, technology and ideas across borders. It is driven by lower transport costs, lower communication costs, financial deregulation and trade liberalisation.
- Impact 1: Higher world trade and economic growth
- World trade as a share of gross world product has roughly doubled since 1990 (World Bank). Specialisation according to comparative advantage has lifted productivity and real GDP, particularly in trade-oriented economies such as Singapore and Vietnam.
- Impact 2: Catch-up growth in developing economies
- China lifted more than 800 million people out of absolute poverty between 1981 and 2019 (World Bank), with average real GDP growth above 8 percent for two decades. India, Vietnam and Indonesia have followed a similar export-led growth model.
- Impact 3: Uneven distribution of gains
- Globalisation has widened the within-country gap between high-skilled and low-skilled workers in advanced economies. Real median wages in the US grew far slower than top-decile wages between 1990 and 2024.
- Impact 4: Convergence on living standards but persistent gaps in development
- GDP per capita has converged for emerging Asia but sub-Saharan Africa has lagged. Human Development Index gaps remain wide.
Markers reward (1) accurate definition, (2) two or three current examples, (3) explicit growth-versus-development distinction.
2019 HSC4 marksOutline the role of transnational corporations (TNCs) in the global economy.Show worked answer →
A 4 mark response needs a TNC definition, two roles, and a recent example.
- Definition
- A TNC is a firm that owns or controls production or service facilities in more than one country, with operations linked across borders.
- Role 1: Foreign direct investment (FDI)
- TNCs account for roughly two-thirds of world FDI flows (UNCTAD). They build factories, services hubs and R&D centres in host countries, creating jobs and tax revenue.
- Role 2: Trade and global value chains
- TNCs organise about 80 percent of world trade through global value chains, in which intermediate inputs cross borders multiple times before final assembly. Apple's iPhone supply chain (designed in California, components from Japan/Korea, assembled in China and Vietnam) is the textbook example.
- Example
- BHP and Rio Tinto are Australian-headquartered TNCs that earn most revenue from iron ore exports to East Asia and reinvest profits across mining operations in Chile, Mongolia and Australia.
Markers reward an accurate definition, two clearly distinct roles, and a current example with a figure.
