What this dot point is asking
OCR wants you to explain government failure, identify its main causes (distorted price signals, unintended consequences, information gaps and administrative costs), and weigh the case for intervention against the risk that it makes things worse. This is a key source of evaluation marks across microeconomics.
What government failure means
Government failure does not mean any intervention with a cost. It means the total costs of intervention exceed the benefits, so the allocation of resources is worse than before. This makes it a powerful evaluation tool: for any proposed policy, a strong answer weighs its intended benefit against the risk of government failure.
The causes of government failure
- Distorted price signals. Subsidies and price controls change prices away from the market level, so they no longer reflect relative scarcity. A subsidy to an inefficient industry keeps resources locked in low-value uses; a minimum price creates surpluses (as with some agricultural support schemes).
- Unintended consequences. Intervention can trigger reactions the government did not foresee. A maximum price (rent control) below equilibrium creates a shortage and a black market; banning a demerit good can push it underground; a sugar tax may push consumers to untaxed but equally unhealthy substitutes.
- Information gaps. Governments rarely have the information to set a tax exactly equal to the marginal external cost, or a subsidy equal to the marginal external benefit. Setting the wrong level means over- or under-correcting the market failure.
- Administrative and enforcement costs. Designing, running and policing a policy uses real resources. If these costs exceed the welfare gain, the intervention fails the cost-benefit test.
- Regulatory capture and political self-interest. Regulators can come to serve the firms they oversee, and politicians may pursue short-term electoral goals (a pre-election giveaway) rather than long-term efficiency.
The case for and against intervention
Government failure is not an argument against all intervention. Large, uncorrected market failures (untaxed carbon, missing public goods, dangerous information gaps) impose big welfare losses of their own. The right approach is comparative: weigh the expected net benefit of a well-designed intervention against both the original market failure and the risk of government failure. Good policy design (using markets where possible, as with tradable permits, and gathering better information) reduces the risk.
Examples in context
- Rent controls. Widely cited as causing shortages, black markets and falling housing quality, the textbook government-failure case.
- The Common Agricultural Policy. Historic EU minimum prices created large surpluses (butter mountains, wine lakes) and distorted production, a classic distorted-signals failure.
- Fuel and energy subsidies. Subsidies that hold prices below cost distort signals, encourage over-consumption and strain public finances, prompting reform in many countries.

OCR H460/01 20215 marksExplain, using an example, what is meant by government failure.Show worked answer →
A short structured question. Define government failure as intervention that leaves society worse off overall, where the costs of the intervention exceed the benefits or it creates a net welfare loss.
Develop with an example and a chain of reasoning. A maximum price (rent control) set below equilibrium creates a shortage, encourages a black market and discourages landlords from maintaining or supplying housing, so the policy meant to help tenants worsens the allocation. Alternatively, a subsidy that props up an inefficient industry distorts price signals and wastes resources.
Markers reward a clear definition (net welfare loss), a named cause (distorted signals, unintended consequences), and a worked example.
OCR H460/01 202212 marksEvaluate the view that the risk of government failure means governments should rarely intervene to correct market failure.Show worked answer →
A levels-of-response question. Knowledge and application: define market failure and government failure, and outline the causes of government failure (distorted price signals, unintended consequences, information gaps, administrative costs, regulatory capture).
Analysis: explain that some interventions risk these failures, for example price controls causing shortages or subsidies entrenching inefficiency.
Evaluation: balance this against the cost of leaving large market failures uncorrected (untaxed pollution, missing public goods). The judgement depends on the size of the original market failure versus the risk and cost of failure, the quality of information, and policy design. Conclude that governments should intervene where the expected net benefit is positive and well-designed, not rarely as a blanket rule.
