Paper 4 — The Global Economy

Topic Brief: The Role of the State

SIGNAL · WEC14 Topic Master Brief — The Role of the State — compiled 2026-09-29. Not affiliated with or endorsed by Pearson Edexcel. Companion to this paper's existing technique-hub build (forge-exam-technique-guide.md, codex-definitions-and-application-bank.md, signal-frequency-and-boundaries.md) — this document does not repeat their content. It takes the per-sub-point frequency counts already published in signal-frequency-and-boundaries.md and the primary citations in research/veridian/WEC14-verified-facts.md and synthesises them into one topic-level view: every real series, the mark-tariff shape, the recurring context type, and a practical "what to expect" for spec section 4.3.5, The Role of the State in the Macroeconomy, as a single topic rather than four separate sub-points.

Method note. No new primary source was fetched for this document — every claim below is traced to WEC14-verified-facts.md (the provenance-checked source) or to the existing SIGNAL frequency table's own citations. Where this document computes something the source files don't state directly (the deduplicated series count below), that arithmetic is shown so it can be checked against the rows it's built from.

1. Scope

Spec 4.3.5 has four numbered items: 4.3.5.1 public expenditure, 4.3.5.2 taxation, 4.3.5.3 public sector borrowing and debt, 4.3.5.4 macroeconomic policies. The per-sub-point series counts already live in signal-frequency-and-boundaries.md §1. This brief asks a different question: across all four sub-points combined, how many of the archive's real series actually tested this topic at all, and what pattern does that testing follow?

2. Real series that have tested this topic

Deduplicating the four sub-point rows in the existing frequency table gives 7 of the 14 fully read series (October 2020–January 2025):

SeriesWhat was testedSub-point
October 2020Fiscal-deficit/national-debt calculation, Q7(a)/(b) (Mauritius)4.3.5.3
January 2022Income-tax percentage vs percentage-point MCQ (45%→47%), Q44.3.5.2
June 2022National-debt Q7(a)/(b) calc (Iran) and a top-income-tax-rate Section C essay, Q84.3.5.3 + 4.3.5.2
October 2022Fiscal-vs-monetary-policy confusion, Q7(d)4.3.5.4
October 2023Laffer-curve income-tax essay, Q7(e) (Pakistan, high earners)4.3.5.2
January 2024National-debt calc, Q7(a)/(b) (Greece)4.3.5.3
January 2025National-debt calc, Q7(a)/(b) and a 35% top-marginal-tax proposal used elsewhere in the same source booklet (Ghana)4.3.5.3 + 4.3.5.2

June 2025 is a real, additional confirmed instance outside this count. Q10 (public expenditure as a % of GDP, Italy, 47.1%→56.7% over 2002–2022) is the first standalone Section C essay found for 4.3.5.1 — but per WEC14-verified-facts.md's own methodology, only that one question from that series was checked, so it is reported separately rather than folded into the "7 of 14."

4.3.5.1, public expenditure, has zero standalone hits inside the 14-series archive itself — the only confirmed test of it anywhere is the June 2025 essay above.

3. The real mark-tariff pattern

Two shapes recur, and one is far more common than the other:

A boundary case worth flagging rather than reusing uncritically: the existing frequency table also lists an October 2023 Q7(d) "IMF/World Bank confusion" under 4.3.5.4. By the spec's own wording, IMF and World Bank roles sit under 4.3.6.3(d) (international institutions), not under 4.3.5.4's own bullet list (fiscal/monetary/exchange-rate/supply-side policy, TNC measures). WEC14-verified-facts.md itself files this example under its 4.3.3 section as an overlap with 4.3.6.3(d), not as clean 4.3.5.4 evidence. Treat that one instance as ambiguous — it doesn't change the "7 of 14" total above, since October 2023 is already counted via its Laffer-curve essay, but it does mean 4.3.5.4 on its own has only one clean confirmed instance (October 2022's fiscal/monetary confusion), not two.
