How do governments raise and spend money, manage their debt, and influence the whole economy?

Public expenditure and taxation, the budget balance and national debt, fiscal and supply-side policy in a global context, and the role of macroeconomic policies in managing the economy.

An Edexcel A-Level Economics A answer to public finances and policies, covering public expenditure and progressive, proportional and regressive taxation, the distinction between the budget deficit and national debt, automatic stabilisers and discretionary fiscal policy, and the use of fiscal, monetary and supply-side policy to manage a global economy.

What this dot point is asking

Edexcel wants you to explain public expenditure and the types of taxation, distinguish the budget deficit from the national debt, explain automatic and discretionary fiscal policy, and explain how macroeconomic policies manage an economy in a global context.

Public expenditure and taxation

The budget balance and national debt

A large deficit can raise demand and growth but adds to debt, raises interest payments and may crowd out private investment. Sustainability depends on the debt-to-GDP ratio and the cost of servicing the debt.

Fiscal, monetary and supply-side policy in a global context

Automatic stabilisers smooth the cycle without new decisions: in a boom, tax revenue rises and benefit spending falls, cooling demand; in a recession the reverse supports it. Discretionary fiscal policy is a deliberate change in spending or tax. Governments combine fiscal policy with monetary policy (interest rates, QE) and supply-side policy (raising productive capacity). In a globalised world these policies interact across borders, so a fiscal expansion can leak abroad through imports and capital flows.

Examples in context

  • UK austerity (2010 to 2015). Spending cuts aimed to reduce the deficit after 2008, a real debate about deficit reduction versus growth in a weak economy.
  • 2020 pandemic borrowing. The UK deficit surged above £300\pounds 300bn as spending rose and revenue fell, pushing debt above 100%100\% of GDP.
  • VAT regressivity. UK VAT at 20%20\% takes a larger share of low incomes, a clear regressive-tax example.
  • Greek debt crisis. Unsustainable debt raised borrowing costs sharply, illustrating why the debt-to-GDP ratio and servicing cost matter.

Q1. Distinguish between a budget deficit and the national debt. [3 marks]

  • Cue. The deficit is the annual shortfall of revenue against spending (a flow); the national debt is the accumulated total of past deficits (a stock).

Q2. Explain why VAT is described as a regressive tax. [3 marks]

  • Cue. It takes a larger proportion of the income of a low earner than of a high earner, so the burden falls more heavily on the poor.

Exam-style practice questions

Practice questions written in the style of Pearson Edexcel exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.

Edexcel 20184 marksA government spends £850\pounds 850bn and raises £790\pounds 790bn in revenue, on a national debt of £2,400\pounds 2{,}400bn. Calculate the budget deficit and the new national debt at year end.

A short calculate question on the deficit-debt distinction.

Budget deficit =spending−revenue=850−790=£60= \text{spending} - \text{revenue} = 850 - 790 = \pounds 60bn (a flow).

The deficit adds to the stock of debt: new national debt =2,400+60=£2,460= 2{,}400 + 60 = \pounds 2{,}460bn.

Markers reward (1) the deficit as spending minus revenue (£60\pounds 60bn), (2) adding the deficit to the existing debt, (3) the deficit-flow versus debt-stock distinction.

Edexcel 202312 marksAssess the view that a government should prioritise reducing its budget deficit during a recession.
Show worked answer →

A 12 mark question (around 8 KAA, 4 evaluation).

KAA: explain that cutting the deficit in a recession (austerity) means lower spending or higher tax, reducing AD via the multiplier and deepening the downturn, while letting automatic stabilisers work supports demand but widens the deficit.

Evaluation: the right choice depends on the debt-to-GDP ratio, the cost of borrowing, market confidence and the output gap; in a deep recession with cheap borrowing, stimulus may be wiser, but unsustainable debt can raise interest costs. Reach a judgement.

Markers reward the multiplier analysis, the sustainability point and balance.
