Overall Paper Verdict

The May 2025 Higher Level Paper 1 represents a classic and highly balanced exam that tests core concepts across microeconomics, macroeconomics, and the global economy. By offering choices between elasticity/market failure (Question 1), fiscal policy applications (Question 2), and trade protection/comparative advantage (Question 3), the IB has remained true to its traditional structure. The overall difficulty is rated as a moderate 3 out of 5, but students must be careful with the strict assessment criteria, which impose hard caps for partial responses.

Where the Marks Lie

In Part (a) questions, marks are awarded for clear definitions, well-structured diagrams, and direct explanations. In Question 1(a), the key is linking YED values (primary < 1, manufacturing > 1, services > 1) to changing sector sizes as real incomes rise. In Question 2(a), the marks are heavily tied to demonstrating how contractionary fiscal policy reduces aggregate demand (AD), leading to lower incomes and thus lower import spending. Question 3(a) requires a clear explanation and diagram of exactly two trade protection methods (such as tariffs or quotas) to access the top level.

Crucial Examiner Pitfalls & Safe Strategies

  • The 'Alternative Policy' Trap: In Question 1(b), because you are asked to evaluate if legislation is the best way to reduce demerit goods, the markscheme dictates a hard cap of 12 marks if you do not analyze alternative policies (like indirect taxes or nudges). You must explicitly compare them.
  • The 'Single Method' Cap: For Question 3(a), explaining only one type of trade protection limits your score to a maximum of 6 out of 10 marks. Ensure you fulfill the plural requirement immediately.
  • Lack of Real-World Examples: Every Part (b) question explicitly demands 'real-world examples'. Simply describing theory without applying it to a specific historical or current case will keep your response in the lower mark bands.

Future Predictions & Revision Priorities

Given the heavy focus on fiscal policy and trade protection in this session, students should anticipate a shift towards monetary policy and exchange rates in the upcoming sessions. Ensure you are highly comfortable with central bank interest rate interventions and floating versus fixed exchange rate mechanisms, as these topics are highly overdue for an extended essay response.
