Demand-side policies explained
Fiscal policy uses government spending and taxation to influence aggregate demand.
Read the full explanation
Government spending includes current spending on public services and capital spending on infrastructure; both inject money into the circular flow. Taxation includes direct taxes on income and profits and indirect taxes on spending; both withdraw money. A rise in spending or a cut in taxation raises aggregate demand, while a fall in spending or a rise in taxation reduces it. The instruments also affect the distribution of income and incentives to work or invest. For example, increasing spending on transport projects raises demand directly, while cutting income tax raises disposable income and consumption. Learners must distinguish spending from taxation and explain how each instrument operates.
Your focus
- Define government spending and taxation as fiscal policy instruments.
- Explain how changes in government spending and taxation affect aggregate demand.
- Distinguish between direct and indirect taxes and between current and capital government spending.
Demand-side policies exam tips
Marking Points
- Government spending is an injection into the circular flow of income and directly adds to aggregate demand.
- Taxation is a withdrawal from the circular flow and reduces disposable income or spending power.
- Direct taxes, such as income tax, affect disposable income and work incentives; indirect taxes, such as VAT, affect prices and consumption.
- Expansionary fiscal policy involves raising government spending or cutting taxation to increase aggregate demand.
- Contractionary fiscal policy involves cutting government spending or raising taxation to reduce aggregate demand.
- The instruments can also affect income distribution, incentives and the government budget position.
Examiner Tips
- 💡Read the question carefully to identify whether it asks about government spending, taxation or both.
- 💡Eliminate options that confuse injections with withdrawals or direct with indirect taxes.
- 💡Use the circular flow of income to justify why a change in spending or taxation affects aggregate demand.
Common Mistakes
- Confusing government spending with taxation: spending injects demand while taxation withdraws demand; correct by linking each to the circular flow.
- Assuming all taxation is direct: indirect taxes such as VAT are also fiscal instruments; correct by classifying taxes into direct and indirect.
- Treating fiscal policy as only taxation: government spending is an equally important instrument; correct by giving examples of both spending and taxation.
