What this lesson teaches
I can explain, draw and evaluate the ways a government corrects market failure, from price controls and taxes to regulation and direct provision.
Syllabus K343, 2.10.3. Government intervention to address market failure: definitions, drawing and interpretation of diagrams, advantages and disadvantages of: maximum and minimum prices in product markets, indirect taxation, subsidies; definitions, advantages and disadvantages of: regulation, privatisation, nationalisation, direct provision of goods and services, quotas, e.g. for the extraction of natural resources
Make a guess
A government sells its state-owned bus company to private owners. What is this called?
- Regulation.
- Nationalisation.
- Privatisation.
Show the answer
Privatisation.
Moving a firm from government to private ownership is privatisation. The opposite is nationalisation.
Governments can also make rules, change who owns firms, supply goods themselves, or limit quantities.
Regulation means rules backed by law, such as a ban on smoking indoors or a limit on pollution. It can work quickly. But it needs inspectors and fines, and firms may find ways around it.
Privatisation is selling state-owned firms to private owners. The search for profit can push them to cut costs. But a private firm may drop services that do not pay. Nationalisation is the opposite: the state takes over a private firm, often one that runs a vital service. It can keep the service going, but the firm may have less reason to cut costs.
Direct provision means the government supplies a good or service itself, often free or cheap. Schools, roads and street lights are examples. It solves the public good problem, but it is paid for by taxes.
A quota is a legal limit on quantity, such as how many fish boats can catch or how much timber can be cut. It protects natural resources. But it limits output and can push up prices.
- Regulation
- Rules backed by law, such as bans and limits.
- Privatisation / nationalisation
- Selling state firms to private owners / the state taking over private firms.
- Direct provision
- Government supplies the good itself, often free.
- Quota
- Legal limit on quantity, such as fish catches.
| Measure | Advantage | Disadvantage |
|---|---|---|
| Regulation | Quick and clear | Costly to enforce; may be evaded |
| Privatisation | Profit motive raises efficiency | Unprofitable services may be cut |
| Nationalisation | Protects vital services | Weaker incentive to cut costs |
| Direct provision | Provides public and merit goods | Funded by taxes; opportunity cost |
| Quotas | Protect scarce natural resources | Limit output; may raise prices |
Worked example: Singapore's vehicle quota
Singapore limits the number of cars on its roads through the Certificate of Entitlement (COE) system.
- Type of intervention: a quota on the number of new vehicles allowed.
- Aim: reduce congestion, an external cost of driving, on a small island.
- Effect: the fixed number of certificates is allocated by bidding, so their price can be very high.
- Drawback: car ownership becomes very expensive, especially for lower-income households.
Watch out for this
Privatisation and nationalisation mean the same thing.
They are opposites. Privatisation moves a firm from government to private ownership. Nationalisation moves a firm from private to government ownership.
Check your understanding
A government builds hospitals and employs the doctors itself instead of leaving care to private firms. What is this called?
- A quota on hospital care
- Direct provision by the state
- A subsidy to private clinics
Show the answer
Direct provision by the state
Right. The government supplies the service itself instead of leaving it to private firms.
Check your understanding
A government limits the tonnes of fish each boat may catch in a year. Which kind of intervention is this?
- A quota
- A maximum price
- A subsidy
- Nationalisation
Show the answer
A quota
Right. A quota is a limit on the quantity that can be produced or extracted.
