Fiscal policy, the budget deficit and public sector debt, the distinction between structural and cyclical deficits, and the policy trade-offs.

What this dot point is asking

WJEC wants you to explain fiscal policy, the budget deficit and public sector debt, the distinction between structural and cyclical deficits, and the trade-offs of using fiscal policy and reducing debt.

The answer

Fiscal policy, the deficit and the debt

An expansionary fiscal stance (higher spending or lower taxes) raises aggregate demand and is used to fight recession; a contractionary stance (lower spending or higher taxes) reduces demand to cool an overheating economy or shrink a deficit. A deficit is a flow (the gap in one year), while the debt is a stock (the total owed); running deficits adds to the debt. The debt is usually judged relative to GDP (the debt-to-GDP ratio), because a larger economy can sustain more debt. The cost of servicing the debt (debt interest) is itself a call on the budget, which is why high debt can constrain policy.

Structural and cyclical deficits and automatic stabilisers

The distinction is central. In a recession, the deficit widens automatically because automatic stabilisers operate: tax receipts fall (people earn and spend less) and benefit spending rises (more unemployment), which cushions the fall in aggregate demand without any policy change. This cyclical part is appropriate counter-cyclical behaviour and disappears as growth returns, so it does not by itself require austerity. A structural deficit, by contrast, persists at full employment and signals that spending plans exceed the sustainable tax base, so it does require deliberate correction. Confusing the two leads to bad policy, such as cutting in a recession when the deficit is mostly cyclical.

Trade-offs of fiscal policy and deficit reduction

Fiscal policy has limits and trade-offs. Crowding out may weaken a fiscal expansion, though it is less likely in a recession with spare capacity. Large deficits raise the debt and its interest costs, can threaten confidence and raise the cost of borrowing, and raise questions of intergenerational fairness. But cutting a deficit through austerity (spending cuts and tax rises) in a recession reduces aggregate demand, can deepen the downturn and may even raise the deficit through lower growth and tax revenue. Government investment spending can raise long-run growth and so be self-financing. So the question "should the deficit be cut?" has no universal answer: it depends on the state of the cycle and whether the deficit is structural or cyclical.

Examples in context

Example 1. UK austerity after the financial crisis. The UK ran large deficits after 2008 as the recession hit revenues and stabilisers operated. The subsequent austerity programme, cutting spending to reduce the deficit, is debated precisely along the lines of this topic: critics argue cutting demand while the economy was weak slowed the recovery, while supporters cite the need to control debt and reassure markets. It is the leading UK case for evaluating the timing of deficit reduction.

Example 2. Pandemic borrowing and the debt ratio. During the pandemic the UK government borrowed heavily to fund furlough and support schemes, pushing the deficit and the debt-to-GDP ratio sharply higher. This illustrates counter-cyclical fiscal policy on a large scale (using the deficit to support demand in a crisis) and reopens the debate over how quickly, and through what mix of growth, tax and spending, the resulting debt should be brought down, a debate that hinges on the cycle and on long-run growth.

Q1. Distinguish between a budget deficit and the national debt. [2 marks]

• Cue. A budget deficit is the amount by which government spending exceeds revenue in a year (a flow); the national debt is the accumulated stock of past borrowing.

Q2. Explain why cutting a budget deficit through austerity in a recession can be counter-productive. [3 marks]

• Cue. Spending cuts and tax rises reduce aggregate demand, deepening the recession and raising unemployment, and the resulting fall in growth and tax revenue can even widen the deficit.
