How do I revise E2E stub topic for AQA A-Level?

Always define key terms like scarcity, opportunity cost, and PPF precisely, as these definitions alone can secure marks.

What exam tips are there for E2E stub topic? (2)

Use diagrams liberally, but ensure they are accurately drawn, labelled, and fully explained in the context of the question.

What exam tips are there for E2E stub topic? (3)

When evaluating, consider both theoretical extremes and real-world constraints, such as market failures or government intervention.

What mistakes should I avoid in E2E stub topic?

Confusing opportunity cost with monetary cost alone, ignoring non-monetary trade-offs.

What are common errors in E2E stub topic exams? (2)

Misinterpreting points inside the PPF as unattainable rather than showing underutilisation of resources.

E2E stub topic

AQA

A-Level

This subtopic introduces the fundamental economic problem of scarcity, exploring how unlimited human wants clash with finite resources, necessitating choice and the incurrence of opportunity cost. It examines how individuals, firms, and governments allocate scarce resources to maximize utility, profits, or social welfare, forming the bedrock of microeconomic analysis and policy evaluation.

Award credit for demonstrating a clear understanding of scarcity by referencing finite resources and infinite wants.
Accurately calculating or quantifying opportunity cost in a given scenario, explicitly stating the next best alternative forgone.
Correctly labelling and interpreting points on a PPF diagram, including efficient, inefficient, and unattainable points.
Explaining how a PPF shift outward represents economic growth with reference to changes in factor quantity or quality.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing opportunity cost with monetary cost alone, ignoring non-monetary trade-offs.
Misinterpreting points inside the PPF as unattainable rather than showing underutilisation of resources.
Failing to recognise that marginal opportunity cost increases when the PPF is concave, leading to weak analysis of trade-offs.
Assuming that all shifts of the PPF are parallel, neglecting factor-specific improvements.
