January 2026 Series Analysis: WEC11 & WEC12
The January 2026 series for Unit 1 (Markets in Action) and Unit 2 (Macroeconomic Performance and Policy) presented a balanced yet highly rigorous assessment of fundamental economic theories and their real-world applications. Across both papers, candidates who demonstrated strong quantitative skills, precise diagrammatic accuracy, and structured evaluative writing excelled. Those who relied on generic definitions or incomplete chains of reasoning struggled to secure top-tier marks, particularly in the high-tariff 14-mark and 20-mark questions.
Unit 1: Microeconomic Insights & Pitfalls
In WEC11/01A, the multiple-choice questions in Section A served as an effective discriminator for conceptual precision. In Section B, drawing the minimum price diagram for the Indian wheat market (Q7) was highly accessible, though several candidates failed to illustrate the increase in minimum price, showing only a single intervention price. Calculating the price elasticity of demand (PED) for sugar in Q10 required precise percentage change calculations; examiners highlighted that candidates must show their intermediate steps to guarantee method marks if their final rounding was off, with the correct answer being \( -0.059 \).
The data response (Q12) on the global cotton and clothing markets tested core market failure and government intervention concepts. Q12(d) required candidates to link environmental external costs (e.g., water depletion and microplastics) to their impact on third parties. A common examiner pitfall was simply listing the environmental damage without explicitly identifying the spillover cost to society. In the 14-mark subsidy question (Q12e), the highest-scoring scripts featured perfectly labelled diagrams showing the rightward shift in supply to \( S + \text{Sub} \) and a structured discussion of both the positive impacts (job protection, cost reduction) and negative impacts (opportunity costs, potential dependency) of US and Chinese subsidies.
Unit 2: Macroeconomic Strengths & Weaknesses
In WEC12/01A, Section A tested fundamental macro relations, such as the Keynesian LRAS curve and the national income multiplier. The calculation of the personal disposable income index in Q9 was generally well-executed, with a correct value of \( 85.03 \) using 2024 as the base year. However, Q11 proved challenging for some who struggled to correctly shift the short-run aggregate supply (SRAS) curve to the left in response to rising oil prices for a net importer.
Section C's focus on South Korea (Q12) highlighted issues of saving ratios and falling investment. Q12(e) was a key differentiator; strong answers analyzed how a fall in investment from \( 35\% \) to \( 31\% \) of GDP reduces aggregate demand (AD) via the circular flow and harms long-run growth by limiting productive capacity. Section D's essays on unemployment (Q13) and macroeconomic conflicts (Q14) demanded deep, multi-stage chains of reasoning. High-scoring responses on Q14 systematically evaluated the trade-offs between economic growth and environmental degradation (using Italy's \( 6\% \) pollution drop as context) or inflation.
Examiner Strategy & Future Preparation
To maximize scores in future series, students should focus on:
- Precise Diagramming: Ensure all axes, curves, and equilibrium points are clearly and accurately labelled (e.g., using "Real Output" and "Price Level" instead of generic "Quantity" and "Price" in macro diagrams).
- Spillover Links: In market failure questions, always connect the negative externality back to a specific, quantified cost on a third party.
- Balanced Evaluation: For high-tariff questions, structure evaluations around magnitude, time lags, and dependency on other economic variables.
