OxfordAQA International GCSE Economics: Fiscal and monetary policy (9214)

This guide covers sections 3.2.3.1 (fiscal policy) and 3.2.3.2 (monetary policy) of the OxfordAQA International GCSE Economics specification (9214), first teaching September 2023, first examined May/June 2025. Both sit in section 3.2, How economies work. Supply-side policies and externalities (3.2.3.3 and 3.2.3.4) are separate units and are not repeated.

All figures below are invented for illustration. Country A, its currency (the aru) and its neighbour’s currency (the bex) do not exist.

3.2.3.1 Fiscal policy and the government budget

Fiscal policy is the government’s use of its spending and taxation to influence the economy. The government budget is the plan of what the government expects to collect in revenue and to spend in a year. Revenue comes mainly from direct taxes (income tax, corporation tax) and indirect taxes (such as VAT). Spending goes on areas such as health, education, welfare and defence, plus interest on past borrowing.

Here is Country A’s budget for one year (bn aru, illustrative):

Revenue	bn aru	Spending	bn aru
Income tax	38	Health	28
Corporation tax	14	Education	22
VAT	30	Welfare	30
Other	18	Defence	8
		Interest on debt	7
		Other	10
Total	100	Total	105

Balanced budget, deficit and surplus

• Balanced budget: government spending equals revenue.
• Budget deficit: spending is greater than revenue.
• Budget surplus: revenue is greater than spending.

Worked example 1. Balance = revenue − spending = 100 − 105 = −5, so Country A runs a deficit of 5 bn aru. If GDP is 400 bn aru, the deficit is 5 ÷ 400 × 100 = 1.25% of GDP.

Expansionary and contractionary fiscal policy

	Expansionary	Contractionary
Spending	Raised	Cut
Taxes	Cut	Raised
Aim	Raise total spending and output	Reduce total spending and price pressure
Typical use	High unemployment, weak growth	High inflation, overheating

How fiscal policy changes income and expenditure

Total spending in the economy is consumption + investment + government spending + exports − imports. Fiscal policy acts on it in two ways.

1. Government spending is itself part of total spending, so a rise adds to it directly.
2. Taxes change households’ disposable income and firms’ profits after tax. Lower income tax leaves households with more to spend. Lower corporation tax leaves firms with more to invest.

Extra spending becomes someone’s income. That person spends part of it, which becomes a third person’s income, and so on. The specification does not name the multiplier, but this knock-on effect explains why the final change in income is larger than the first injection.

Worked example 2. The government of Country A raises spending by 4 bn aru. Assume that out of every extra 1 aru of income, 0.75 aru is spent again in Country A (the rest is saved, taxed or spent abroad).

Round	Extra income (bn aru)
1	4.00
2	4 × 0.75 = 3.00
3	3 × 0.75 = 2.25
4	2.25 × 0.75 = 1.6875
and so on

The rounds shrink towards zero. The total is 4 ÷ (1 − 0.75) = 16 bn aru, or 4% of a 400 bn aru economy.

Worked example 3 (tax cut versus spending). Compare 6 bn aru of extra government spending with a 6 bn aru tax cut, using the same 0.75 figure.

• Spending: the whole 6 enters the first round. Total = 6 ÷ 0.25 = 24 bn aru.
• Tax cut: households spend only 0.75 × 6 = 4.5 in round one. Total = 4.5 ÷ 0.25 = 18 bn aru.

The tax cut gives a smaller boost because part of it is saved straight away. Its advantage is that households choose how to spend it.

Using fiscal policy to achieve objectives

Objective	Fiscal action	Chain of reasoning
Economic growth	Spend on infrastructure; cut corporation tax	More spending and investment, so higher output now; better roads and equipment raise what the economy can produce later
Lower unemployment	Raise spending or cut income tax	Higher demand, so firms produce more and hire more workers
Controlling inflation	Cut spending or raise taxes	Lower demand, so less pressure on prices
Balance of payments	Raise taxes to reduce spending on imports	Lower income means households buy fewer imported goods, so the current account deficit narrows
Reducing inequality	Raise taxes on high incomes; spend more on benefits	Money moves from higher to lower earners, so the gap in disposable income narrows; higher taxes may weaken incentives to work

Policies can conflict. Expansion that cuts unemployment may raise inflation and increase imports. Always say which objective gains and which suffers.

Consequences of a deficit

A deficit is paid for by borrowing, which adds to the national debt, the total owed by the government.

Worked example 4. Country A starts the year with debt of 175 bn aru, and the interest rate on its debt is 4%.

• Interest: 175 × 0.04 = 7 bn aru, as in the budget table.
• After the 5 bn aru deficit, debt is 180 bn aru, or 45% of GDP (it was 43.75%).
• Next year’s interest at the same rate: 180 × 0.04 = 7.2 bn aru.
• Interest is already 7 ÷ 100 = 7% of revenue and equals 31.8% of education spending. The opportunity cost is hospitals or schools not funded.

Consequences of a deficit:

• Higher debt and higher interest payments, which leave less for public services.
• A larger burden on future taxpayers, who must meet the interest.
• Short-run support for demand, which helps in a downturn.
• If the economy is already at full capacity, extra spending may only raise prices.

Consequences of a surplus

Worked example 5. In a later year Country A collects 108 bn aru and spends 102 bn aru. The surplus is 108 − 102 = 6 bn aru. Used to repay debt, it cuts debt from 180 to 174 bn aru.

Consequences of a surplus:

• Debt falls, so interest payments fall.
• The government can cut taxes or spend more later.
• Taxing more than is spent takes money out of the economy, so demand can fall and growth slow.
• The surplus may come from spending cuts that harm services.

A balanced budget avoids both debt growth and a drag on demand, but it leaves the government little room to respond to a recession.

Evaluating fiscal policy

• Time lags: it takes time to plan, pass and spend a budget.
• Spare capacity: stimulus raises output only if resources are idle. Otherwise prices rise. Suppose a 6 bn aru injection produces 24 bn aru in total (worked example 3) but the economy has only 15 bn aru of spare capacity. About 9 bn aru of the demand then pushes up prices instead.
• Leakages: if households save or buy imports, the effect is smaller.
• Politics: tax rises and spending cuts are unpopular and hard to carry out.
• Debt: the cost of borrowing is paid later.

3.2.3.2 Monetary policy

Monetary policy means changing interest rates, through the central bank or government, to steer the economy. Changing the rate changes the cost of borrowing and the reward for saving. This is the main tool you need.

The transmission mechanism

Suppose the base interest rate is raised. Then:

1. Borrowing costs more and saving pays more.
2. Households borrow and spend less, and save more.
3. Firms find investment more expensive, so they invest less.
4. Total spending in the economy falls.
5. Demand-pull pressure on prices eases, so inflation slows.

Worked example 6 (effects on decisions). The rate rises by 1.5 percentage points.

• A household with a 150,000 aru variable-rate mortgage: interest rises from 4,500 aru (3%) to 6,750 aru (4.5%), a rise of 2,250 a year or 187.50 a month. Less spending money is left.
• A saver with 10,000 aru: interest rises from 150 aru (1.5%) to 300 aru (3.0%). Saving is more attractive.
• A firm with an 80,000 aru loan: interest rises from 4,800 aru (6%) to 6,000 aru (7.5%), a rise of 1,200. Marginal projects are shelved.

Worked example 7 (effect on total spending). Country A’s GDP is 400 bn aru: consumption 260, investment 60, government spending 70, net exports 10. After a rate rise, consumption falls 3, investment falls 2 and net exports fall 1 (see below), a first-round fall of 6. With a knock-on factor of 1.5, the fall is 6 × 1.5 = 9, so GDP is 400 − 9 = 391 bn aru, a fall of 2.25%.

Controlling inflation

Inflation is measured by the change in a price index.

Worked example 8. Country A’s price index rises from 108.0 to 111.2. Inflation = (111.2 − 108.0) ÷ 108.0 × 100 = 2.96%. If the target is 2%, inflation is almost one percentage point too high, so the central bank considers raising rates to slow demand-pull inflation. Rates cannot easily cure cost-push inflation, where the cause is higher costs on the supply side. Raising rates then cuts output as well.

Achieving other objectives

Objective	Rate change	Effect
Economic growth	Cut	Cheaper borrowing raises consumption and investment, so output rises
Lower unemployment	Cut	Higher demand, so firms take on workers
Balance of payments (current account)	Cut	A lower rate tends to lower the currency’s value, so exports become cheaper abroad and imports dearer
Price stability	Rise	See above

Worked example 9 (exchange rate). An export costs 80 aru. When 1 aru = 2.00 bex, the foreign price is 160 bex. If the aru rises to 2.20 bex, the price is 176 bex, 10% dearer, so exports and net exports tend to fall. A foreign import costing 55 bex falls from 27.5 aru to 25 aru, 9.1% cheaper, so imports tend to rise. A higher rate that lifts the currency can therefore worsen the current account, while a lower rate can improve it. The effect on the balance of payments depends on how much demand responds to price.

Evaluating monetary policy

• Time lags: the full effect can take many months.
• Confidence: if people expect a slump, lower rates may not raise borrowing.
• Who gains: borrowers lose and savers gain when rates rise; the reverse when they fall.
• Conflict: raising rates to cut inflation can raise unemployment and slow growth.
• One tool: a single rate applies to the whole economy, whatever the needs of one region or industry.

Common errors

• Treating the deficit and the national debt as one thing. The deficit is the shortfall in a single year, whereas the debt is everything owed after many years of borrowing.
• Saying a surplus is always good. State the cost in lost demand.
• Describing a rate rise as raising spending because savers earn more. State the net effect on borrowers.
• Applying monetary policy to cost-push inflation without noting its limits.
• Forgetting to link every policy to an objective in the final sentence.
