Government expenditure (G) explained
Total government expenditure includes spending on goods, services, investment and transfer payments.
Read the full explanation
Its level is influenced by two main factors. First, the trade cycle: in a downturn, total spending rises automatically due to higher transfer payments like unemployment benefits, while tax receipts fall. These act as automatic stabilisers. However, in the aggregate demand equation (AD = C + I + G + (X-M)), 'G' excludes transfers. Second, fiscal policy involves deliberate government decisions about spending and taxation. Expansionary fiscal policy raises G (spending on goods and services) to stimulate aggregate demand; contractionary fiscal policy cuts G to reduce inflationary pressure or the budget deficit. Distinguish automatic cycle effects on transfers from discretionary policy choices affecting G.
Your focus
- Explain how the trade cycle influences the level of total government expenditure through transfer payments.
- Explain how fiscal policy influences the level of government expenditure on goods and services (G).
- Distinguish automatic stabilisers from discretionary fiscal policy changes.
Government expenditure (G) exam tips
Marking Points
- Identifies the trade cycle as an influence: downturns automatically raise total government expenditure through higher transfer payments (e.g. benefits).
- Identifies fiscal policy as an influence: discretionary government decisions to raise or lower spending on goods and services (G) and taxation.
- Explains the automatic stabiliser mechanism linking the cycle to total expenditure and tax revenues, without directly changing G.
- Distinguishes expansionary fiscal policy (raising G) from contractionary fiscal policy (cutting or restraining G).
- Applies the influences to a real or hypothetical economy, such as a recession increasing total expenditure via benefits.
Examiner Tips
- 💡Learn a clear chain of reasoning: recession → lower incomes → higher benefit claims → total government expenditure rises.
- 💡Use a current or historical example of a fiscal stimulus or austerity programme to show deliberate discretionary policy.
- 💡In multiple-choice questions, eliminate options that confuse automatic cycle effects on transfers with discretionary fiscal policy affecting G.
Common Mistakes
- Treating the trade cycle and fiscal policy as the same thing; correction: the cycle causes automatic changes to transfers and taxes, while fiscal policy is a deliberate choice.
- Including transfer payments in the AD component 'G'; correction: G represents government spending on goods and services, while transfers affect AD indirectly via consumption.
- Confusing government expenditure with taxation; correction: expenditure is spending, while taxation is the main revenue source.
- Assuming automatic stabilisers directly change G; correction: they operate through transfer payments and tax revenues.
