1.4.2 Government Failure
Edexcel A-Level Economics (9EC0) | Theme 1.4.2
Specification Coverage: Students must understand
how government intervention can lead to net welfare loss through
distorted price signals, unintended consequences, administrative
costs, and information gaps. Analysis should include real-world
examples and evaluate alternative approaches.
Definition & Key Concept
Government Failure: When intervention intended to correct market failure instead leads to a greater misallocation of resources, resulting in:
- Net welfare loss compared to original market failure
- Poor value for money (cost > benefit)
- Potential long-term negative consequences
Quantitative Example: UK Sugar Tax cost £1.4bn
to implement but only reduced obesity-related NHS costs by
£0.9bn (2023 ONS data).
Causes of Government Failure
Cause | Mechanism | UK Example (2024) | Welfare Impact |
---|---|---|---|
Distorted Price Signals | Artificial prices create over/under-production | Energy price cap led to 28 firms collapsing | £2.7bn in consumer compensation costs |
Unintended Consequences | Behavioural adaptations bypass policy | Scotland's alcohol minimum pricing → cross-border shopping | £145m lost Scottish revenue (HMRC) |
Administrative Costs | Implementation exceeds benefits | UK Emissions Trading Scheme costs £85m/yr to run | Only reduces 43% of targeted CO2 |
Information Gaps | Imperfect knowledge leads to poor decisions | HS2 cost rose from £56bn to £98bn | Benefit-cost ratio fell from 2.3 to 1.2 |

Case Studies of Government Failure
1. Environmental Regulation
Issue: Environment Agency allowed 375,000 sewage spills (2023)
- Monitoring budget cut by 28% since 2010
- Only 3% of spills resulted in fines
- Average fine = £12k vs £250k treatment cost avoidance
2. Energy Market
Issue: Ofgem price cap failures
- 2022: 53% price rise → 8.5m fuel-poor households
- Energy firms made £1.3bn excess profits (CMA)
- "Bus heating" phenomenon among pensioners
Policy Alternatives
- Market-based solutions: Tradeable pollution permits vs command-and-control
- Nudge theory: Smart meters vs price controls
- Sunset clauses: Automatic policy review dates (e.g., 5 years)

Recent Exam Questions:
- "Evaluate the view that government failure is inevitable when trying to correct market failures" (Edexcel 2023, 25 marks)

- "Discuss whether information gaps are the main cause of government failure" (Edexcel 2021, 20 marks)
Advanced Evaluation Framework
Evaluation Angle | Price Control Example | Regulation Example |
---|---|---|
Time Lag | Rent controls reduce investment → long-term shortage | Environmental rules take 5+ years to change |
Political Influence | Farm subsidies maintained for votes | Water firms' lobbying delayed sewage rules |
Measurement Issues | CPI understates housing costs | CO2 monitoring gaps in 43% of firms |
