Cambridge IGCSE Economics 0455
Syllabus points
- Describe the role of government in the economy — locally, nationally and internationally.
What governments do
Governments play several roles in a modern economy, acting at local, national and international levels. Their main roles are as:
- Producer — providing goods and services such as state education, healthcare, defence and roads.
- Employer — governments employ large numbers of workers (teachers, nurses, civil servants).
- Regulator — making and enforcing laws (safety standards, pollution limits, competition rules).
- Taxer and spender — raising revenue through taxes and spending it on public services and support.
- Manager of the economy — using policies to control inflation, unemployment and growth.
Key definitions
| Term | Definition |
|---|---|
| Public sector | The part of the economy owned and run by the government. |
| Regulation | Rules the government sets to control how markets and firms behave. |
Why governments intervene
Markets do not solve every problem. Governments intervene to:
- Correct market failure — provide public goods, tax demerit goods, control pollution.
- Reduce inequality — through taxes and benefits.
- Stabilise the economy — smoothing booms and slumps.
- Provide essential services many people could not otherwise afford.
Government roles: producer, employer, regulator, taxer/spender, and manager of the whole economy.
Levels of government
- Local — services such as rubbish collection, local schools and roads.
- National — defence, national policy, income tax.
- International — trade agreements and cooperation with other countries.
Worked example
A government builds and staffs public hospitals (producer and employer), passes laws limiting factory pollution (regulator), taxes cigarettes and funds benefits for the unemployed (taxer/spender), and adjusts interest rates and spending to keep the economy stable (manager). This shows the range of roles a single government plays.
Common exam mistakes
- Listing only one or two roles — learn the full range.
- Confusing the public sector (government) with the private sector (firms).
