What this dot point is asking
Eduqas wants you to explain fiscal policy (government spending and taxation), the budget balance and national debt, the classification of taxes (direct or indirect, progressive or regressive), automatic stabilisers, and the strengths and weaknesses of fiscal policy in managing aggregate demand. Fiscal policy is the first of the three demand-side and supply-side policy levers.
Government spending and taxation
Because government spending (G) is a direct component of AD, and taxation affects consumption and investment, fiscal policy shifts the AD curve, with the effect amplified by the multiplier. It can also pursue microeconomic and distributional goals (redistribution, correcting market failure).
The budget balance and the national debt
A rising national debt raises debt-interest costs and can crowd out other spending, but borrowing to fund productive investment can also raise long-run growth, so the sustainability of the debt (relative to GDP) matters more than its level alone.
Types of tax
- Direct taxes are levied on income and wealth (income tax, corporation tax, national insurance). Indirect taxes are levied on spending (VAT, excise duties).
- A progressive tax takes a rising proportion of income as income rises (UK income tax). A proportional tax takes a constant proportion. A regressive tax takes a falling proportion as income rises, so it bears more heavily on the poor (many indirect taxes, such as VAT, are regressive because the poor spend a larger share of income).
The mix of taxes shapes both incentives and the distribution of income, linking fiscal policy to the equity-efficiency trade-off.
Automatic stabilisers and discretionary policy
Strengths and weaknesses of fiscal policy
- Strengths. It directly affects AD; it can be targeted at specific regions, sectors or groups; it can address both demand and supply (infrastructure, education); and automatic stabilisers work without delay.
- Weaknesses. Time lags (recognition, implementation through the Budget, and impact); the risk of crowding out (government borrowing raising interest rates and squeezing private investment); a worsening budget deficit and national debt; and political constraints (spending is hard to reverse). Its effect is weak against structural unemployment, which needs supply-side measures.
Examples in context
- Pandemic support. The furlough scheme and business grants were large discretionary fiscal expansions to prevent a demand collapse, sharply raising borrowing.
- Austerity. Post-2010 spending restraint aimed to cut the structural deficit, illustrating contractionary fiscal policy and its growth costs.
- Progressive income tax. UK income-tax bands and the personal allowance are the textbook progressive tax and a key automatic stabiliser.
Try this
Q1. Distinguish between a budget deficit and the national debt. [3 marks]
- Cue. Deficit is the annual gap between spending and revenue; national debt is the accumulated total owed from past deficits.
Q2. Explain how automatic stabilisers help to smooth the economic cycle. [4 marks]
- Cue. In a downturn, tax receipts fall and benefit spending rises automatically, supporting AD; in a boom the reverse cools demand, all without any new policy decision.

Eduqas Component 2 20214 marksA government's income tax takes from a worker earning and from a worker earning . Calculate the average tax rate for each and state whether the tax is progressive or regressive.Show worked answer →
A short calculate question. The average tax rate is tax paid divided by income.
Lower earner: . Higher earner: .
Because the average tax rate rises with income (20 per cent to 30 per cent), the tax is progressive. Markers reward both average rates and the correct classification (progressive, because the average rate rises with income), not simply that the higher earner pays more in cash terms.
Eduqas Component 3 (macro) 202012 marksEvaluate the use of expansionary fiscal policy to reduce unemployment in a recession.Show worked answer →
A levels-of-response essay. Knowledge and application: define expansionary fiscal policy (higher government spending and/or lower taxes) and explain it raises AD, which, with spare capacity in a recession, raises output and employment (a rightward AD shift), amplified by the multiplier. Draw the AD-AS diagram.
Analysis: develop the chain to lower cyclical unemployment.
Evaluation: weigh the drawbacks: a larger budget deficit and rising national debt, possible crowding out, time lags (recognition, implementation, impact), and limited effect if confidence is low. The effect on structural unemployment is weak. Conclude with a supported judgement: effective for cyclical unemployment with spare capacity, but constrained by the public finances and lags.
