# The Examiner's Vault: Cracking the Monopoly Essay
The monopoly question is one of the most predictable essays in Paper 4. It appears in some form almost every single exam sitting, and yet the examiner report consistently notes that most candidates fail to identify the mathematical condition for allocative inefficiency.
The Question: > **"Explain how monopoly power can result in allocative inefficiency and evaluate the effectiveness of deregulation in addressing this form of market failure."** > *(20 Marks)*
📝 The Bullet Point Plan: * **Define** monopoly power (price maker, high barriers to entry). * **Define** allocative inefficiency (P > MC). * **Explain** profit maximisation at MC = MR, leading to restricted output. * **Evaluate** deregulation: benefits of contestability vs natural monopoly limitations.
✍️ The Basic Answer:
[DEFINE] Monopoly power refers to the ability of a firm to act as a price maker, typically occurring when a firm dominates a market with high barriers to entry. Allocative inefficiency occurs when resources are not distributed according to consumer preferences — technically, where Price (P) does not equal Marginal Cost (MC).
[EXPLAIN] A firm with monopoly power faces a downward-sloping demand curve. To maximize profits, the monopolist restricts output to the point where MC = MR. Because the MR curve lies below the AR curve, the price charged (read off the AR curve) is higher than the marginal cost. This means P > MC, and a deadweight welfare loss exists.
[APPLY] For instance, patented pharmaceutical firms charge extremely high prices for essential drugs, extracting consumer surplus and leaving some patients priced out of the market entirely.
