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

These notes condense 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. For full explanations start with the study guide, then test yourself with the practice questions. See also the course hub, the checklist, the government objectives notes and the free diagnostics.

Every figure here is invented. Country B and its money units are fictional.

Key definitions

Term	Meaning
Fiscal policy	Government decisions on what to spend and what to tax, aimed at steering the economy
Government budget	Planned revenue and spending for a year
Balanced budget	Spending = revenue
Budget deficit	Spending > revenue; paid for by borrowing
Budget surplus	Revenue > spending
National debt	Total the government owes from past borrowing
Monetary policy	Changing interest rates to steer the economy
Expansionary	Aims to raise total spending
Contractionary	Aims to reduce total spending

Fiscal policy at a glance

Tool	Expansionary	Contractionary
Government spending	Up	Down
Income tax	Down	Up
Corporation tax	Down	Up
Effect on demand	Up	Down

Chain for a tax cut: lower income tax, higher disposable income, more consumption, more demand, firms raise output and hire, income rises.

Chain for spending: the government buys goods or builds projects, firms and workers gain income, they spend part of it, and income rises by more than the first injection.

Calculation reminders

Balance and size of deficit

1. Add up revenue.
2. Add up spending.
3. Balance = revenue − spending. Negative means deficit.
4. Percentage of GDP = balance ÷ GDP × 100.

Example (Country B, bn units). Revenue 62, spending 58. Balance = +4, a surplus. With GDP of 250, that is 4 ÷ 250 × 100 = 1.6% of GDP. Debt of 90 falls to 86, which is 36.0% of GDP falling to 34.4%.

Knock-on effect of extra spending

1. Find the share of extra income spent again in the country (call it s).
2. Total change = first injection ÷ (1 − s).

Example. Spending rises by 2.5 and s = 0.6. Total = 2.5 ÷ 0.4 = 6.25. The knock-on factor is 1 ÷ 0.4 = 2.5.

Tax cut of 4 with s = 0.6. First-round extra spending = 0.6 × 4 = 2.4. Total = 2.4 ÷ 0.4 = 6.0, less than the 10 that 4 of direct spending would give (4 ÷ 0.4 = 10).

The specification does not name the multiplier. Treat this as the knock-on effect of spending.

Fiscal policy and objectives

Objective	Action	Reasoning
Growth	Spending on roads, schools; lower business taxes	Demand and investment rise; productive capacity rises
Employment	Spending up or taxes down	Demand rises, so labour demand rises
Price stability	Spending down or taxes up	Demand falls, so price pressure eases
Balance of payments	Taxes up	Lower incomes, fewer imports
Reducing inequality	Taxes on high incomes up; benefits up	Disposable incomes move closer together; limit: weaker incentives

Conflicts to mention: growth and jobs may raise inflation and imports; cutting inflation may raise unemployment.

Deficit versus surplus

	Deficit	Surplus
Debt	Rises	Can be repaid
Interest	Rises	Falls
Demand	Supported	Weakened
Future	Burden on later taxpayers	More room for tax cuts or spending
Danger	Less money for services; inflation near full capacity	Less demand; may come from harmful cuts

A balanced budget avoids debt growth but leaves little room to support a recession.

Monetary policy at a glance

Rate rise: borrowing dearer, saving rewarded, consumption and investment fall, demand falls, inflation slows. Rate cut: the reverse; demand, output and jobs tend to rise, but prices may rise faster.

Objective	Rate move	Why
Control inflation	Up	Less demand, less demand-pull pressure
Growth	Down	Cheaper borrowing, more spending and investment
Employment	Down	Higher demand, more hiring
Balance of payments	Down (usually)	Weaker currency, cheaper exports, dearer imports

Calculation reminders

• Interest on a loan = amount × rate. Loan of 20,000 at 5% = 1,000; at 3.5% = 700; saving of 300.
• Saver: 5,000 at 2% earns 100; at 3.5% earns 175.
• Inflation = (new index − old index) ÷ old index × 100. Index 120.0 to 123.0: 3.0 ÷ 120 × 100 = 2.5%.

Must-know distinctions

• Deficit vs debt: one year’s gap vs the running total.
• Fiscal vs monetary: taxes and spending vs interest rates.
• Demand-pull vs cost-push: demand tools work on the first; on the second they mainly cut output.
• Expansionary vs contractionary: direction of the change in demand.

Evaluation checklist

• Time lags
• Spare capacity
• Leakages into saving and imports
• Confidence
• Who gains and loses (borrowers, savers, taxpayers)
• Conflict with another objective
• Short run versus long run

Exchange rate reminder (Country B, illustrative)

A lower interest rate tends to lower the exchange rate. Suppose 1 unit of Country B’s money = 1.50 zed (the neighbour’s currency), and it falls to 1.30 zed.

• An export priced at 30 units: foreign price = 30 × 1.50 = 45 zed, then 30 × 1.30 = 39 zed. It is 13.3% cheaper abroad, so export demand tends to rise.
• An import priced at 39 zed: home price = 39 ÷ 1.50 = 26 units, then 39 ÷ 1.30 = 30 units. It is 15.4% dearer, so import demand tends to fall.

Both effects point the same way, towards a smaller current account deficit. How large the change is depends on how strongly buyers respond to price.

Building a full-chain answer

Use this order for any “explain how policy X achieves objective Y” question.

1. Name the policy change and its direction.
2. State the immediate effect (disposable income, borrowing cost, firms’ costs).
3. State the effect on spending (consumption, investment, government spending, net exports).
4. State the effect on total demand and output, then on prices or jobs.
5. Link back to the objective in the question.
6. Add one limit: a time lag, spare capacity, a leakage or a conflict.

Short example. Income tax is cut. Households keep more of each pay cheque. They spend part of it, so consumption rises and firms sell more. Output rises and firms hire, so unemployment falls. The gain may be small if households save most of the cut, and demand may pull up prices.

Choosing between fiscal and monetary policy

Situation	Likely tool	Reason to prefer it	Limit
Deep recession, firms not borrowing	Fiscal expansion	Government spending adds demand directly	Raises the deficit and debt
Demand-pull inflation, public finances sound	Rate rise	Quick to announce, no new taxes	Borrowers lose, jobs may fall
Need to protect public services	Rate move	Avoids cutting spending	Slow to take effect
Low confidence	Fiscal expansion	Does not depend on borrowers	Takes time to plan

Quick self-test

1. Define a budget deficit.
2. Country B takes in revenue of 71 and spends 68. Work out the balance and name it.
3. Calculate the balance in question 2 as a percentage of GDP of 300.
4. State two expansionary fiscal actions.
5. Spending rises by 3 and s = 0.5. Calculate the total change.
6. Explain one cost of running a budget surplus.
7. A price index rises from 150.0 to 153.0. Calculate inflation.
8. Explain how a rate rise reduces inflation.
9. A loan of 40,000 has its rate cut from 6% to 4.5%. Calculate the fall in annual interest.
10. Explain one way a lower interest rate could help the balance of payments.

Answers

1. Spending greater than revenue in a year.
2. 71 − 68 = +3, a surplus.
3. 3 ÷ 300 × 100 = 1%.
4. Any two: raise government spending; cut income tax; cut corporation tax.
5. 3 ÷ (1 − 0.5) = 6.
6. Taxing more than is spent removes money from the economy, so demand and growth may slow; or services may be cut to produce the surplus.
7. (153 − 150) ÷ 150 × 100 = 2%.
8. Borrowing costs more and saving pays more, so households and firms spend and invest less, demand falls and price pressure eases.
9. Interest falls from 2,400 (6%) to 1,800 (4.5%), a fall of 600.
10. A lower rate makes the country less attractive to foreign savers, so demand for its currency falls and the exchange rate falls. Exports become cheaper abroad and imports dearer, so net exports tend to rise.

Where marks are usually lost

• Calling a deficit the national debt.
• Giving a policy but no chain of reasoning to the objective.
• Saying a surplus is good without a cost.
• Reversing the direction of a rate change.
• Forgetting that borrowers and savers are affected in opposite ways.
• Using demand-side tools for cost-push inflation without a limit.
• Giving a calculation answer without units or working.
• Listing evaluation points without saying which matters most.
