Paper 4 — The Global Economy

Definitions and Application Bank

CODEX · WEC14 Definitions Masterlist and Application/KAA Bank — compiled 2026-09-28. This is the content/knowledge-reference layer for this paper, sitting alongside content/veridian/technique-hub/wec14/forge-exam-technique-guide.md (the technique layer, completed the same day) and drawing primarily on research/veridian/WEC14-verified-facts.md (the primary research bank — 14 real exam series, October 2020–January 2025, plus one narrower June 2025 pass, each already independently verified there against primary Pearson PDFs).

WEC14 Definitions Masterlist and Application/KAA Bank (Unit 4: Developments in the Global Economy)

What this is, and how it was built

This document completes WEC14's previously-3-file technique-hub stub with the content/knowledge-reference layer: Part 1 is a definitions masterlist covering every key term the real spec names, section by section; Part 2 is a bank of short (2–4 sentence) application/KAA paragraphs, each grounded in a real country, statistic or scenario a Pearson mark scheme or examiner report actually used.

What this is not. It does not re-teach content/veridian/curriculum/wec14/'s seven lessons, which already carry full worked chains, diagrams, trap-taxonomies and level-exemplars for every spec point, individually audited bullet-by-bullet against real mark schemes. It does not reproduce the one real past question and its full level-exemplar in content/veridian/question-bank/wec14.ts. And it does not restate anything from the FORGE technique guide — no timing budget, no tariff-by-tariff marking mechanics, no danger phrases. This is the compact reference layer: a term you can look up in ten seconds, and a paragraph of real grounding for a KAA point you don't have to re-derive from scratch.

How it was built, honestly. This document is a second-order synthesis, not a fresh independent primary-source audit. Its factual claims are drawn from WEC14-verified-facts.md, which was itself built and repeatedly cross-checked against primary Pearson PDFs (pdftotext -layout/-raw, cross-checked, with several independent-tester re-verification passes logged inline) — this document trusts that prior verification rather than re-fetching every PDF again. Where a definition needed checking for consistency with what this course already teaches, the relevant curriculum file was read or grepped directly (confirmed working definitions for terms of trade, Marshall-Lerner/J-curve, the Laffer curve, absolute/relative poverty, the Gini coefficient, and the market-orientated/interventionist strategy list — see "Sources used" at the end). The prior AI-authored CODEX stub at content/veridian-classic/source/P4-WEC14/03-CODEX/ was read in full for depth and style calibration; per the facts bank's own cross-check, it covers only comparative advantage and exchange-rates/BoP/competitiveness (two of WEC14's six spec sections), and it contains the misattributed country-gate quote the facts bank already caught and corrected (January 2024's gate belongs to Q8, not Q9) — nothing from that stub is reused here without that correction already applied.

Citation convention. Three tiers, marked inline:

Where a term could not be grounded in the spec, a real mark scheme, or the curriculum's own derivation, it is flagged rather than invented — see "Genuine gaps flagged" at the end, which also states plainly which parts of this document rest on thinner evidence than the rest.

PART 2 — Application / KAA Bank

Organised by spec section; each entry is 2–4 sentences grounded in a real country, statistic or scenario a Pearson mark scheme or examiner report actually used, with the series/question cited. One entry is explicitly labelled illustrative-only, matching this course's own convention for a "country of your choice" instruction.

4.3.1 Globalisation

Vietnam's FDI inflows [MS-consistent, Oct 2024 source booklet]. Japan was the largest source of FDI into Vietnam, with inflows from Japan alone reaching around $3.4bn — real, quotable grounding for FDI's reasons and recipient-country impact applied to a specific economy rather than discussed only in the abstract.

Zambia's copper dependence [Oct 2021 source booklet]. Zambia's economy and its currency, the kwacha, are heavily exposed to the world copper price — a real, recurring illustration of how globalisation's benefits (export markets, extractive FDI) and its costs (commodity-price exposure, terms-of-trade vulnerability) sit inside the same economy at once.

China's trade-agreement network and reshoring pressure [MS: June 2025 Q7(a)/(b)/(d)]. China's source booklet cites 28 free-trade agreements including RCEP, with the WTO's dispute-resolution and rule-setting roles credited directly against this context; the same series' evaluation band separately credits reshoring — TNCs simplifying their supply chains — as a genuine counter-trend to the falling-transport-cost mechanism.

Trickle-down, stated and immediately rebutted [MS: Jan 2022/Oct 2022]. A real KAA point credits rising top-end incomes eventually raising incomes for everyone via trickle-down — but the same paper's own evaluation band states there is little evidence this happens in practice; use the pair together, not the claim alone.

Container shipping's twenty-fold rise [MS: Jan 2022 Q8 stem]. Global container-shipping volumes rose from around 100 million tonnes in 1980 to 2 billion tonnes by 2020 — roughly a 1,900% increase — real, quantified grounding for falling transport costs as a cause, though the same series' evaluation band credits the mirror-image point that landlocked or no-seaport countries benefit far less from it.

4.3.2 Trade and the global economy

UK/CPTPP accession, 2021 [MS: Jan 2023 Q8]. The UK's 2021 application to join the CPTPP trading bloc is this paper's clearest real trading-bloc scenario. Credited KAA benefits include economies of scale, greater bargaining weight in trade negotiations and an improved current-account position; credited evaluation includes trade diversion, loss of sovereignty over trade policy, and the risk that a bloc's largest members dictate terms to a smaller new entrant.

Gibraltar and Greece's worsening terms of trade, 2000–2020 [MS: Oct 2023 Q8]. Gibraltar's terms of trade worsened by 44.6% and Greece's by 14.3% over that period — real, quotable figures for a terms-of-trade essay that, unusually, carries no country-gate instruction, since its stem asks generically about "a country" rather than "a country of your choice."

Ghana's national-debt calculation and 35% top-tax proposal [MS: Jan 2025 Q7(a) and Section C stem]. Ghana's source booklet supplied the real Q7(a) national-debt calculation on which around 30% of that series' candidates still lost at least one of two marks — typically the percentage-vs-percentage-point error — and separately proposed a 35% top marginal income-tax rate as the basis for a Laffer-curve-relevant essay.

Steel tariffs [MS: Jan 2025 Q6]. A steel-tariff scenario was the named weakest MCQ of the January 2025 series — real, current grounding for tariff-diagram literacy (consumer surplus, producer surplus, government revenue, deadweight loss) rather than a generic textbook tariff.

China's currency management and Southeast Asia's Prebisch-Singer exposure [MS: Jan 2024 Q9; June 2023 Q7(e)]. China's currency controls limiting appreciation are credited as a real factor shaping trade patterns; separately, Southeast Asian primary-product exporters are the mark scheme's own named real-world link to the Prebisch-Singer hypothesis on worsening terms of trade.

4.3.3 Balance of payments, exchange rates and competitiveness

Turkey's lira depreciation, 2018–2020 [MS: Jan 2022 source booklet]. Three real, linked graphs — interest rates, inflation and the exchange rate — anchor this series' exchange-rate content: genuine grounding for the interest-rate/inflation/exchange-rate transmission chain rather than an invented scenario.

Zambia's kwacha and the Marshall-Lerner condition [MS: Oct 2021 Q7(e)]. The mark scheme credits the kwacha's response to a change in Zambia's balance of trade as depending explicitly on the price elasticity of demand for exports and imports, naming the Marshall-Lerner condition directly — a genuine evaluation point built on a named mechanism.

Pakistan's rupee and the current-account/financial-account balance [MS: Oct 2023/Oct 2024]. Pakistan's rupee fell 27% against the US dollar in 2022, with the same context crediting the IMF's role (loans to ease a current-account deficit); a separate, real evaluation point from a different series states the current account is "relatively minor" next to capital-flow-driven depreciation for many developing countries.

Japan's 230%+ national debt and yen appreciation [MS: Oct 2024 Q10, Eval band]. A real, citable counter-example to "high debt always weakens a currency": Japan's national debt exceeding 230% of GDP has not prevented yen appreciation, because underlying economic strength can outweigh short-term macroeconomic management.

New Zealand's productivity gap [MS: June 2022 Q9]. New Zealand's productivity rate was 40% lower than the average of other advanced economies in 2020 — real, quantified grounding for relative productivity as a competitiveness measure, paired with the same mark scheme's own point that productivity may matter less where wage costs are already low, or is hard to measure for a service-heavy economy.

4.3.4 Poverty and inequality

Global Gini coefficient, 2000–2014 [MS: Jan 2021 source booklet]. A real global Gini time series anchors this series' inequality-measurement content, alongside the same series' own sharply-evidenced relative-poverty definitional trap (6% full marks).

Peru and Georgia's Lorenz-curve/Gini MCQs [MS: Oct 2022/Oct 2023]. Two real, separately-evidenced direction-of-shift traps — candidates reading a Lorenz-curve or Gini-coefficient movement backwards — confirm this is a recurring Section A failure mode across different countries and series, not a one-off.

Sweden and the USA's rising income inequality, 2007–2022 [MS: Jan 2024 Q8]. A real developed-country pair anchoring the paper's richest inequality-causes essay: credited causes span wage differentials, the top-1% income share, pension erosion, tax-rate changes, globalisation, low-wage immigration, weakened union power, and (dated but genuinely credited) the 2020–2022 health crisis's uneven impact on younger workers.

4.3.5 The role of the state

Italy's public expenditure, 47.1% → 56.7% of GDP, 2002–2022 [MS: June 2025 Q10]. A genuine, standalone Section C essay built around public expenditure as a share of GDP rather than folded into a taxation or deficit essay, with real KAA content spanning LRAS effects and the multiplier and real evaluation content on financial and resource crowding out — plus a mark-scheme note allowing positive effects to be credited as KAA or Evaluation interchangeably.

Pakistan's income-tax rise on high earners and the Laffer curve [MS: Oct 2023 Q7(e)]. A real essay crediting the Laffer-curve mechanism on both sides: rising rates may raise revenue and help reduce the fiscal deficit, or may cut revenue if the rate is pushed beyond the optimal point.

Greece's debt crisis and the ECB/IMF's roles [MS: Jan 2024 source booklet]. Real grounding for national-debt significance (debt-servicing costs, intergenerational equity) and for the IMF/World Bank role-conflation trap that recurs specifically inside balance-of-payments-crisis source booklets.

Iran's national debt and US-reimposed trade restrictions [MS: June 2022 source booklet]. Real grounding for how an external shock interacts with an existing fiscal position — exactly the "inability to control external shocks" problem spec item 4.3.5.4e names directly.

4.3.6 Growth and development

South Sudan's HDI decline, 2010–2022, despite oil-driven GDP swings [MS: Jan 2024 Q10]. South Sudan's HDI fell from 0.43 to 0.39 over that period — real, quotable grounding for why growth (GDP) and development (HDI) are separate claims, since this is a recorded HDI fall over a period of real, if volatile, oil-driven GDP.

Pakistan (0.60) vs Argentina (0.85), HDI comparison [MS: Jan 2022 Q10]. A real, quantified pair anchoring a growth/development-constraints essay — genuine grounding for opening a country-gated Section C answer with an HDI comparison rather than growth-rate figures alone.

Niger's microfinance vs Mali's interventionist human-capital strategy [MS: Oct 2021 Q3 MCQ]. Niger (HDI 0.35 in the real MCQ stem) is the mark scheme's own real example of microfinance correctly classified as market-orientated, contrasted against Mali's real interventionist (human-capital) choice — useful because it shows the two-category split tracking who delivers the fix, not simply whether a market failure exists.

Debt relief, illustrated for "a developing country of your choice." [MS: June 2021 Q9, real question and full mark scheme.] The real mark scheme credits saved debt-service repayments closing the savings and foreign-currency gaps, funding infrastructure, human capital and environmental debt-for-nature swaps, set against real evaluation counterweights (dependency culture, moral hazard, IMF/World Bank conditionality, and eligibility limits that exclude some developing countries from relief altogether). Illustrative only, not part of the mark scheme: a country such as Mozambique, a genuine HIPC/debt-relief recipient, answers the question's own open "country of your choice" instruction — the same illustrative pairing question-bank/wec14.ts's own level-exemplar uses, flagged there in identical terms.

Chad's trade-liberalisation strategy and Indonesia's commodity dependence [MS: Jan 2025 MCQ; June 2024 source booklet]. Two further real, series-specific country examples for 4.3.6.3's market-orientated-strategy list and 4.3.6.2's primary-product-dependency constraint respectively — genuine grounding rather than a generic "a developing country" placeholder.
