What this dot point is asking
NESA wants you to explain how capital moves internationally (FDI versus portfolio investment), the role transnational corporations play in organising global production through value chains, how technology has extended globalisation into services that were previously non-tradeable, and the causes and consequences of the international movement of labour (migration, remittances, brain drain). Expect a 4 to 8 mark short answer, or a component of a longer extended response on the features of the global economy.
The answer
Investment: FDI versus portfolio investment
International investment takes two broad forms.
Foreign direct investment (FDI) is investment that gives the foreign investor a lasting management interest in an enterprise abroad, conventionally defined as owning 10% or more of the voting shares. FDI can be:
- Greenfield investment - building new production or service facilities from scratch, e.g. a car manufacturer opening a new assembly plant.
- Mergers and acquisitions (M&A) - buying an existing foreign firm outright or taking a controlling stake.
Portfolio investment is the purchase of foreign financial assets - shares, bonds, managed funds - without a controlling management interest. It is generally more liquid and volatile than FDI, since portfolio holdings can be sold quickly in response to changing interest rates or sentiment, whereas a factory cannot be relocated overnight.
Transnational corporations (TNCs) and global value chains
A transnational corporation (TNC) is a firm that owns or controls production or service facilities in two or more countries, with strategy, finance and production decisions coordinated across borders from a head office. TNCs are the dominant vehicle for FDI: multinational giants such as Apple, Toyota, Nestle and Australian-headquartered BHP and Rio Tinto each operate across dozens of countries.
TNCs organise roughly 80 percent of world trade through global value chains (GVCs), in which the design, components, assembly and distribution of a single good cross multiple national borders before it reaches the final consumer. The textbook example is the smartphone: designed in the United States, with semiconductors from Taiwan and South Korea, camera modules from Japan, and final assembly in China or Vietnam. Each border crossing counts as trade, which is one reason gross world trade has grown faster than gross world product for much of the post-war period.
Motives for FDI fall into three categories:
- Market-seeking - entering a market to sell directly to local consumers (e.g. a car manufacturer building a plant inside a large market to avoid tariffs and transport costs).
- Efficiency-seeking - relocating labour-intensive stages of production to lower-cost countries (e.g. garment assembly in Bangladesh or Vietnam).
- Resource-seeking - securing access to raw materials (e.g. BHP's mining investments in Chile and Mongolia).
Effects of inbound FDI on a host economy. Benefits include an inflow of capital, technology transfer, management expertise and employment. Costs include profits that are eventually repatriated to the parent company overseas (recorded as a debit in the primary income component of the current account), the risk that local firms are crowded out by larger foreign competitors, and reduced domestic policy leverage if the TNC is a dominant employer.
Technology, transport and the tradeability of services
Technology has changed WHAT can be traded internationally, not just how cheaply. Falling communication costs (submarine fibre, satellite links, cloud computing, mobile broadband) mean services once considered non-tradeable - accounting, legal advice, customer support, software engineering, medical diagnosis - can now be delivered remotely across borders. This is the basis of offshoring: a firm relocating part of its own production or service process abroad, distinct from simply importing a finished good from an unrelated foreign supplier. Falling transport costs (containerisation, larger bulk carriers, air freight) have had the same effect on goods, letting components travel between GVC stages cheaply. Australia's own IT and digital services exports have grown strongly over the past decade (ABS), an example of the technology dimension of globalisation working in Australia's favour.
The international movement of labour
Labour is the least mobile of the factors that globalise, constrained by visa systems and national borders, but international migration for work is a significant and growing feature of the global economy.
Push factors (reasons workers leave their home country) include limited domestic job opportunities, lower relative wages, and conflict or political instability. Pull factors (reasons workers are drawn to a destination) include higher wages, strong demand for specific skills (healthcare, construction, technology, agriculture) and family reunification pathways. Destination countries such as Australia manage skilled migration through dedicated visa pathways, including the Skills in Demand visa (subclass 482), which replaced the former Temporary Skill Shortage visa from December 2024.
Remittances - money migrant workers send home to family - are a major and often underappreciated financial flow. Global remittances to low- and middle-income countries totalled around $685 billion in 2024 (World Bank), a figure that frequently exceeds total FDI flowing into those same economies, making remittances a critical source of foreign income and poverty reduction for countries such as the Philippines and India.
Brain drain versus brain gain. When skilled workers (doctors, engineers, scientists) emigrate permanently, the source country loses the return on its education investment and can face shortages in its own labour market - this is brain drain. Where emigrants later return with enhanced skills, savings and international networks, or where the prospect of emigration raises domestic investment in education, economists describe this as brain gain or "brain circulation".

foundation3 marksDistinguish between foreign direct investment (FDI) and portfolio investment, and give one example of each.Show worked solution →
Distinction (2 marks). Foreign direct investment (FDI) gives the investor a lasting, controlling management interest in a foreign enterprise (conventionally 10% or more of voting shares); portfolio investment is the purchase of foreign financial assets (shares, bonds) with no controlling interest.
Examples (1 mark, either accepted). FDI: a mining company building a new plant abroad (greenfield investment) or buying an existing foreign firm (M&A). Portfolio investment: an Australian superannuation fund buying shares in a foreign company with no management role.
Marking spine: an accurate control-based distinction (2), a correctly matched example for at least one type (1). Reversing the definitions, or giving two examples with no distinction, caps at 1.
foundation4 marksDefine a transnational corporation (TNC) and explain what a global value chain (GVC) is, using one named example.Show worked solution →
- TNC definition (1 mark)
- A firm that owns or controls production or service facilities in two or more countries, with strategy and production coordinated across borders.
- GVC explanation (2 marks)
- A global value chain is a production process in which the design, components, assembly and distribution of a good cross multiple national borders before reaching the final consumer, with each stage located where it is cheapest or most efficient to perform.
- Example (1 mark)
- The smartphone supply chain: designed in the United States, with components from Japan and South Korea, and final assembly in China or Vietnam.
Full marks need the TNC definition, an accurate GVC explanation (not just "trade between countries"), and a specific, correctly described example.
core5 marksA described dataset (owned, ExamExplained; illustrative, modelled on UNCTAD data) shows global FDI inflows in US$ trillion for selected years: 2015 about 1.9, 2018 about 1.5, 2020 about 1.0, 2022 about 1.6, 2024 about 1.3. Describe the trend shown, and explain it with reference to global economic conditions.Show worked solution →
A 5-mark "describe and explain" rewards (i) an accurate reading of the trend with figures and a turning point, and (ii) an explanation using a global economic cause, not just a restatement.
Describe the trend (about 2 marks). Global FDI inflows fell from about $1.9 trillion in 2015 to about $1.5 trillion in 2018, then dropped sharply to about $1.0 trillion in 2020 - roughly half the 2015 level - before partially recovering to about $1.6 trillion in 2022 and easing again to about $1.3 trillion in 2024. Identify 2020 as a sharp trough rather than a gradual decline.
Explain with a cause (about 3 marks). The 2020 trough reflects the COVID-19 pandemic, which paused new greenfield projects and cross-border mergers amid demand uncertainty and travel and construction restrictions. The 2022 recovery reflects post-pandemic reopening and pent-up investment, while the 2023-24 fall reflects tighter global financing conditions (higher interest rates raising the cost of funding new projects) and elevated geopolitical and trade-policy uncertainty discouraging long-horizon commitments.
Marking spine: accurate trend with the anchor figures and the 2020 trough identified (2), the COVID-19 cause for the trough (1), at least one further 2022-24 cause (interest rates or geopolitical uncertainty) (2). A description with no cause, or a cause never linked to the data, caps at 3. (Figures are an owned ExamExplained dataset modelled on UNCTAD World Investment Report series; treat as illustrative.)
core6 marksExplain how TWO of the following have changed the size or structure of the global economy: transnational corporations, technology, or the international movement of labour.Show worked solution →
A 6-mark "explain" needs two clearly distinct features, each with a mechanism and a current, dated example.
Feature 1: Transnational corporations (about 3 marks). TNCs organise around 80% of world trade through global value chains (UNCTAD/WTO), splitting production across countries via foreign direct investment - design in one country, components in a second, assembly in a third - to exploit comparative advantage in cost and skill. Example: Apple's smartphone supply chain spanning the United States, South Korea, Japan and Vietnam/China.
Feature 2: Technology (about 3 marks). Falling communication costs (cloud computing, mobile broadband) have made previously non-tradeable services - accounting, software, customer support - internationally tradeable through offshoring, extending globalisation beyond goods and physical FDI. Example: Australia's IT and digital services exports have grown strongly over the past decade (ABS).
Marking spine: two distinct features (not two examples of the same feature), each with a mechanism (2 marks each) and a current, named example (1 mark each). One feature developed with the other merely named stays mid-band.
core5 marksOutline the causes of international labour migration, and explain one economic cost and one economic benefit it can generate for a source (sending) country.Show worked solution →
- Causes (about 2 marks)
- Push factors (limited domestic job opportunities, lower relative wages, conflict/instability) and pull factors (higher wages, strong demand for specific skills, family reunification) jointly drive workers to migrate for employment.
- Cost for the source country (about 1.5 marks)
- "Brain drain": when skilled workers such as doctors or engineers emigrate permanently, the source country loses the return on its education investment and can face domestic skill shortages.
- Benefit for the source country (about 1.5 marks)
- Remittances - money migrants send home - are a major income flow; global remittances to low- and middle-income countries totalled around $685 billion in 2024 (World Bank), often exceeding FDI into those economies, funding household consumption and reducing poverty.
Marking spine: at least one push and one pull factor named (2), an accurate brain drain mechanism (1.5), an accurate remittance benefit with a dated figure (1.5). Listing causes with no cost/benefit, or a cost/benefit with no data, caps at 3.
exam7 marksAssess the extent to which transnational corporations benefit host developing economies.Show worked solution →
A 7-mark "assess" needs a sustained, balanced argument with a mechanism on both sides, current data and a clear judgement, not a one-sided list of "pros and cons".
Band 6 PLAN.
Thesis: TNCs deliver substantial benefits to host developing economies through capital, technology transfer and employment, but these gains are partly offset by profit repatriation and competitive pressure on domestic firms, so the net benefit depends heavily on the host country's bargaining position and complementary domestic policy.
Argument 1 - FDI transfers capital, technology and jobs. Evidence: global FDI inflows run at around $1.3 to 1.5 trillion a year (UNCTAD), much of it directed by TNCs into manufacturing and resource extraction in developing economies. Mechanism: a TNC's greenfield investment or acquisition brings capital that the host economy could not otherwise mobilise domestically, along with management practices and technology that raise local productivity, plus direct and indirect employment.
Argument 2 - global value chain integration lifts export capacity and growth. Evidence: TNCs organise around 80% of world trade through global value chains (UNCTAD/WTO); Vietnam's integration into electronics and garment GVCs has coincided with sustained export-led growth. Mechanism: hosting one stage of a GVC (e.g. component assembly) gives a developing economy access to global markets it could not reach alone, transferring know-how over time.
Argument 3 - the gains are partly offset by repatriation and crowding-out. Evidence: profits earned by foreign-owned firms are recorded as a debit in the primary income component of the current account when repatriated to the parent company, and large TNCs can out-compete smaller domestic firms for finance, skilled labour and market share.
Counter-weight / judgement: the net benefit is not automatic; it depends on the host government's ability to negotiate favourable terms (local content requirements, tax arrangements) and to invest complementary gains (education, infrastructure) domestically, but on balance the evidence supports TNCs as a substantial, if unevenly distributed, net benefit to host developing economies.
Model paragraph (Argument 1). The clearest channel through which TNCs benefit a host developing economy is the transfer of capital and technology that domestic saving alone could not mobilise. Global FDI inflows of around $1.3 to 1.5 trillion a year (UNCTAD) are substantially directed by transnational corporations into manufacturing, resource extraction and services in developing economies, funding factories, ports and processing facilities that raise the host country's productive capacity. Beyond the capital itself, TNCs bring management practices, quality standards and technology that often diffuse to local suppliers and joint-venture partners over time, while direct employment in TNC facilities frequently pays above the informal-sector wage. This mechanism is why many developing-economy governments actively compete to attract FDI rather than restrict it, even though the gains are not distributed evenly across the workforce.
Marker's note: markers reward a genuine ASSESS structure (benefits AND costs, each with a mechanism, then a judgement) rather than a list; at least two distinct benefit channels (capital/technology transfer, GVC/export access) and at least one cost mechanism (repatriation, crowding-out); current, dated data (the UNCTAD FDI figure, the 80% GVC-trade figure); and an explicit, qualified judgement rather than "it depends" with no conclusion. A one-sided answer, or costs/benefits with no mechanism, cannot reach the top band.
