October 2025 Examiner Verdict
The October 2025 Edexcel International AS Level Economics papers (Unit 1 and Unit 2) present a balanced, mid-level challenge that rewards precise economic terminology, clear graphical representation, and contextual application. Unit 1 (Markets in Action) forces candidates to engage with microeconomic fundamentals using the real-world context of Japan's rice market, while Unit 2 (Macroeconomic Performance and Policy) centers on the structural economic problems and policy choices in developing economies like Kenya. Overall, the papers demand that students move beyond generic explanations to deliver analytical structures backed by accurate mathematical reasoning and diagrammatic mechanics.
Where the Marks are Found
A significant portion of the marks resides in the high-tariff evaluation questions in Sections C and D of both papers. In Unit 1, Market Failure and Price Determination are the key performance drivers, particularly Section C's 14-mark question on the external costs of rice farming and Section D's 20-mark evaluation of market intervention tools (indirect taxes and minimum prices). In Unit 2, Economic Growth and Macroeconomic Objectives dominate the marking structure. Specifically, Section C’s 14-mark discussion on structural unemployment remedy policies and Section D's 20-mark evaluative essays on economic growth costs/benefits require students to synthesize multiple macroeconomic objectives to access high-level marks.
Examiner Pitfalls and Crucial Misconceptions
Examiners highlighted recurring gaps in diagrammatic precision. In Unit 1, market failure externality graphs frequently lacked correct labeling or misplaced the deadweight welfare loss triangle. Students often failed to demonstrate the vertical difference representing the marginal external cost. In Unit 2, aggregate demand and aggregate supply (AD/AS) diagrams suffered from generic axes labeling (e.g., using 'P' or 'Q' instead of 'Average Price Level' and 'Real Output' \( Y \)), which led to immediate mark penalties. Crucially, many students conflated disinflation with deflation, incorrectly asserting that disinflation represents a general fall in price levels rather than a slowdown in the positive inflation rate.
Winning Strategy for Future Candidates
To maximize scores, candidates must practice structural accuracy across all diagram types. Every shift in supply, demand, AD, or LRAS must be accompanied by explicit changes in price and quantity indicators. For Section B calculations, showing the raw formula (such as the multiplier formula \( K = \frac{1}{1 - MPC} \) or index numbers) guarantees partial credit even if arithmetic errors occur. Finally, high-scoring essays in Section D must establish a solid platform with clear definitions and contextualize arguments with reference to specific countries (e.g., Vietnam or the USA) rather than offering purely theoretical arguments.
Prediction and Future Trends
Based on the relative absence of international trade topics in this series, future exams are highly likely to place greater weight on protectionist measures (tariffs and quotas) and exchange rate intervention mechanisms. Additionally, issues relating to labor market imperfections and minimum wage policy are overdue for higher-tariff coverage. Students should ensure these areas are thoroughly revised alongside core monetary and fiscal policy mechanisms.
