From the checked teaching notes for this specification point.
The idea
For example, lowering interest rates reduces borrowing costs, stimulating investment and consumption, which shifts AD to the right. This can lead to higher economic growth and lower unemployment, but may increase inflationary pressures. Conversely, contractionary fiscal policy aims to reduce inflation but might harm growth. The impact of these policies depends on factors such as the multiplier size, the initial level of economic activity, and consumer confidence.
What earns the marks
- Identification of the type of macroeconomic policy as expansionary or contractionary, and fiscal or monetary.
- Explanation of the transmission mechanism through which the policy affects aggregate demand or aggregate supply.
- Analysis of the policy's impact on key macroeconomic indicators such as inflation, unemployment, and economic growth.
- Recognition of the limitations of the policy, such as time lags or crowding out.
- Application of the multiplier effect to explain the final impact on national income.
Common mistakes and how to put them right
Confusing the effects of monetary and fiscal policy.
Put it right: Clearly distinguish between changes in interest rates or money supply for monetary policy, and government spending or taxation for fiscal policy.
Assuming a policy will have an immediate effect.
Put it right: Acknowledge the time lags involved in implementing and transmitting macroeconomic policies.
Ignoring the shape of the AS curve when analysing AD shifts.
Put it right: Explain that the impact on price level and real GDP depends on the amount of spare capacity in the economy.
Exam tips
- Use AD/AS diagrams to visually demonstrate the intended impact of the macroeconomic policy on the price level and real output.
- Always consider the context of the economy, such as whether it is in a recession or experiencing a boom, when evaluating policy effectiveness.
- Link the policy impact to the components of aggregate demand to build a logical chain of reasoning.

- Fiscal policy
- Macroeconomic policy involving changes in taxation or government spending, which can be expansionary or contractionary.
- Monetary policy
- Macroeconomic policy involving changes in interest rates or the money supply, such as quantitative easing.
- Aggregate demand and supply
- Changes in taxation, government spending, interest rates or quantitative easing affect these, and their interaction determines the impact on the economy.
- Economic indicators
- Key macroeconomic measures such as inflation, unemployment and economic growth, on which the impact of a policy is analysed.
