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.

| 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.

A government sets the maximum number of tonnes of fish that boats may catch each year. What is this?
- A quota
- A subsidy
