1.4.2 Government Failure
Definition of Government Failure
Government failure: when government intervention to correct a market failure results in a net welfare loss or a less efficient allocation of resources than before the intervention.
In other words, the cost of the intervention outweighs the benefit.
Causes of Government Failure
Distortion of Price Signals
Government price controls, such as minimum or maximum prices, can disrupt the market's signalling and incentive functions.
Example: A minimum price for agricultural goods can signal producers to increase supply, which may lead to overproduction and waste.
Unintended Consequences
Economic agents seek to maximise their own welfare, so they may respond to policies in ways that undermine the original aim.
- Black markets may emerge, for example in illegal drugs.
- Consumers may engage in cross-border shopping to avoid taxes or regulations.
- Firms and consumers may find loopholes that weaken the policy.
Excessive Administrative Costs
The cost of implementing, monitoring, and enforcing a policy can be greater than the social welfare gain it creates.
This means the intervention may represent poor value for money.
Information Gaps
Governments also suffer from imperfect information and bounded rationality, just like consumers and firms.
This can lead to poorly designed policies that fail to achieve their aims or create unforeseen negative effects.
Political Self-Interest and Short-Termism
Policies may be designed to win votes rather than maximise social welfare.
Governments may also focus on short-term political cycles rather than long-term economic benefits.
Examples of Government Failure
Regulatory failure: environmental agencies may fail to prevent significant pollution, or energy price caps may fail to prevent excessive profits while consumers still struggle.
Poorly designed policies: large public IT projects may run massively over budget and still fail to meet their objectives, such as the NHS IT programme.
Unintended consequences: indoor smoking bans may lead to more outdoor heating and litter, while alcohol minimum pricing may encourage cross-border shopping.
Exam Preparation
- Core concept: Government failure is the worsening of an outcome due to intervention rather than simply the existence of market failure.
- Evaluation: Weigh up potential government failure against market failure and judge whether intervention is likely to improve or worsen the outcome.
- Application: Use specific real-world examples rather than vague statements.
- Balanced argument: The possibility of government failure is one reason economists may prefer market-based solutions, such as taxes and subsidies, over direct provision or heavy regulation where possible.
