常见错误

1. 1high涉及分数: 4Role of government in microeconomics

   Explaining only one non-price determinant or benefit when the Part (a) question specifically requests 'two', which limits the candidate's score to a maximum of 6/10 marks.

   如何避免: Carefully read the prompt. Use explicit signposts such as 'The first determinant is...' and 'The second determinant is...' to ensure you fully develop two distinct concepts with balanced detail.
2. 2medium涉及分数: 2Role of government in microeconomics

   Failing to show a clear shaded area representing the total cost of a subsidy to the government on demand/supply diagrams.

   如何避免: Illustrate the subsidy by drawing a vertical distance between the original supply curve and the post-subsidy supply curve. Shade the entire rectangle from the consumer price to the producer price over the new equilibrium quantity.
3. 3high涉及分数: 2Exchange rates

   Labeling exchange rate diagram axes with generic markers such as 'P' and 'Q' instead of relative designations.

   如何避免: Always label the vertical axis as the price of the base currency in terms of the quote currency (e.g., 'USD per ARS' or 'Price of Kina in USD') and the horizontal axis as 'Quantity of [Currency Name]'.
4. 4high涉及分数: 2Measuring economic activity and illustrating its variations

   Forfeiting calculation marks by writing down only the final numerical answer without showing intermediate formulas or steps.

   如何避免: Write the full formula first (e.g., GDP deflator or PED), show the substituted values in a clear step-by-step format, and ensure the final answer includes the proper units (%, currency symbols, or millions/billions).
5. 5high涉及分数: 6Arguments for and against trade control/ protection

   Writing one-sided, unbalanced evaluations in Part (b) or Part (g) questions, such as listing only the drawbacks of trade protection without evaluating the advantages.

   如何避免: Structure essays to show balanced viewpoints. Evaluate policies using short-run versus long-run timelines, impacts on key stakeholders, and comparative alternative strategies before drawing a reasoned conclusion.
6. 6high涉及分数: 6Economic growth and/or economic development strategies

   Using hypothetical examples (like 'Country X' or 'Firm Y') or generic regions ('in Africa') instead of concrete, localized, real-world case studies.

   如何避免: Build a revision database of specific country actions (e.g., Argentina's 2023-2024 economic shock reforms or Papua New Guinea's extraction tax policy) and directly integrate these details into your analytical arguments.
7. 7medium涉及分数: 4Market failure—public goods

   Confusing public goods with government-provided merit goods like state education or health services.

   如何避免: Define public goods strictly by their two defining properties: non-excludability and non-rivalry. Remember that merit goods are excludable and rivalrous, but underprovided by the free market.
