IBonomicsForms of Government InterventionSL
MicroeconomicsA simple diagram showing four common forms of government intervention in markets: subsidies, taxes, price controls, and direct provision.
Curves and elements
- Subsidy
- Government financial support that lowers costs of production or consumption and encourages market activity.
- Tax
- Government charge placed on producers or consumers that raises costs and discourages market activity.
- Price Controls
- Government intervention through maximum or minimum prices to influence market outcomes.
- Direct Provision
- The government supplies a good or service itself rather than leaving it fully to the private market.
Key explanations

A subsidy is financial support given by the government to producers or consumers to encourage production or consumption.
- 2
A tax is a charge imposed by the government, which increases costs and can reduce production or consumption.
- 3
Price controls are government-set minimum or maximum prices, such as price floors and price ceilings.
- 4
Direct provision occurs when the government provides goods or services itself, often to improve access and equity.
