Overall Exam Verdict

The October/November 2025 Economics (0455) papers represent a classic, balanced Cambridge assessment. Paper 12 (Multiple Choice) tested fundamental mechanics with standard calculations of PES, Social Benefit, and Average Costs, while Paper 22 (Structured Questions) demanded highly developed application and evaluation skills. The structured paper featured a heavy emphasis on demographic changes (Japan's aging population and labor shortage), market interventions (subsidies and taxing demerit goods), and the limitations of macroeconomic policies.

Where the Marks Are Won or Lost

High-scoring candidates secured easy marks on numerical and direct questions, such as calculating the percentage of foreign workers (\( 2.5\% \)), identifying causes of aging populations, and defining 'market equilibrium' and 'average total cost'. However, significant marks were lost in the 8-mark discussion questions. In particular, many students struggled to construct a balanced argument when evaluating whether tax cuts reduce a current account deficit (Question 5d) or whether economic growth directly translates to higher Human Development Index (HDI) values (Question 4d).

Examiner Pitfalls to Avoid

  • Unbalanced Discussions: In the 8-mark 'Discuss' questions, candidates frequently provided a one-sided argument. For instance, in Q3d, many wrote extensively on why perfume should be taxed as a luxury but failed to analyze why taxing basic food or demerit foods might be more beneficial or progressive.
  • Weak Diagram Mechanics: In Q1e, some students failed to accurately label the axes as 'Price' and 'Quantity' or shifted the supply curve instead of the demand curve following a decrease in population.
  • Misconceptions about Central Banks: Candidates often confused the roles of commercial banks with central banks, missing the fact that central banks manage monetary policy (e.g., interest rates) rather than holding deposits for the general public.

Key Preparation Strategy

To excel in future sessions, candidates must focus heavily on the relationship between macroeconomic targets and social indicators. Practice drawing and shifting demand and supply diagrams for a wide range of real-world scenarios. More importantly, build a structured framework for policy analysis: always evaluate both the direct intention of a policy (e.g., tax cuts increasing investment) and its unintended consequences (e.g., tax cuts raising disposable income, leading to higher import spending and widening a current account deficit).
