Demonstrate understanding of the efficiency of different market structures using marginal analysis
This standard asks you to explain how different types of markets (like monopolies and perfect competition) make decisions about what price to charge and how much to produce, using the idea of marginal analysis. You need to show whether these market structures produce efficiently and use graphs to support your explanations with specific labels and numbers.
You identify the key aspects of marginal analysis (like MR = MC for profit-maximisation), make basic graph changes with labelling, and explain allocative efficiency by noting whether D = S or if deadweight loss exists.
You explain the 'why' and 'how' with specific graph references, show accurate graphs, and use examples to demonstrate that fixed costs don't affect marginal cost while variable costs do.
You compare and contrast outcomes across different situations, give multiple valid reasons for your answers, use phrases like 'at the original output, MR > MC means the firm is missing marginal profits,' and integrate all graph details with accurate economic terminology throughout.
