Overall Verdict & Exam Structure

CCEA AS 1 (Markets and Market Failure) provides a balanced and rigorous assessment of microeconomic principles. The examination is divided into three sections: Section A (25 marks) tests fundamental concepts, quantitative skills, and diagrammatic analysis; Section B (35 marks) tests data comprehension, PPF dynamics, merit goods, and policy evaluation via a case study on the NHS; and Section C (20 marks) provides an essay choice between government prohibition of disposable vapes and income/wealth inequality.

Where the Marks Are Won

A substantial 35% of the total paper is concentrated in Section B, where high-scoring candidates demonstrate precision in microeconomic diagrams—specifically shifting the PPF inward due to resource constraints and illustrating the underconsumption of merit goods where \( \text{MSB} > \text{MPB} \). Furthermore, quantitative marks in Section A (economic rent calculation \( \frac{1}{2} \times \text{base} \times \text{height} \) and elasticity adjustments) offer straightforward points for mathematically confident students.

Examiner Pitfalls & Common Mistakes

  • Tax Incidence Diagrams: Candidates often fail to clearly delineate consumer burden versus producer burden when demand is relatively elastic (\( |\text{PED}| > 1 \)).
  • Merit Goods vs Public Goods: Confusing merit goods (excludable and rivalrous with positive externalities) with pure public goods (non-excludable and non-rivalrous) is a persistent error.
  • Data Analysis without Manipulation: In 5-mark comparison questions, quoting raw numbers without calculating percentage differences or proportions limits marks to Level 1.

Exam Strategy & Prediction

Time allocation is vital: allocate ~25 minutes to Section A, ~40 minutes to Section B, and ~25 minutes to Section C. Ensure all diagrams are fully labelled with equilibria (\( P_1, Q_1 \)), shifts clearly arrowed, and deadweight loss or surplus areas shaded where applicable. Future series are highly likely to test government intervention remedies such as minimum pricing, tradable permits, and labour market minimum wage dynamics.
