Fiscal and monetary policy are core Section B evaluate topics; expansionary vs contractionary, tools and limitations tested consistently.
Monetary policy is the central bank's use of interest rates and the money supply to influence the economy.
The central bank is independent of the elected government in most modern economies (e.g. the Bank of England, the European Central Bank, the US Federal Reserve). Independence is meant to keep monetary decisions away from short-term political pressure.
The main tool is the the central bank charges on its loans to commercial banks. Changes in the base rate flow through to all other interest rates in the economy: mortgages, business loans, savings accounts, credit cards.
When the central bank raises interest rates, borrowing becomes more expensive and saving becomes more attractive. Households and firms spend less and save more, so falls.
What follows:
The combined effect is lower aggregate demand, which slows demand-pull inflation. Higher rates are the central bank's main weapon against inflation.
When the central bank cuts interest rates, borrowing becomes cheap and saving becomes unattractive. Households and firms spend and invest more, so aggregate demand rises.
What follows:
The combined effect is higher aggregate demand, which lifts growth and reduces unemployment. Lower rates are the central bank's main weapon in a recession.
Identifying monetary policy measures (2 marks)
What comes up: a 2-mark question asking you to identify or state two monetary policy measures.
Write: name any two of: (1) changes in interest rates, (2) changes in the money supply, (3) changes in the foreign exchange rate (if the central bank manages the rate).
Watch out: the mark scheme accepts quantitative easing as an alternative way of expressing a change in money supply, but does not expect it by name. Do not list fiscal tools (taxation, government spending) — those belong to a different policy family entirely.
"Discuss whether a cut in interest rates will [reduce inflation / stimulate growth]" (8 marks)
What comes up: an 8-mark Discuss question on whether lower interest rates achieve a macroeconomic aim. The examiner expects you to show the transmission mechanism and then challenge it.
Write (both sides): Why lower interest rates will help: (1) Borrowing becomes cheaper and saving less attractive, so households spend more and firms invest more, raising total (aggregate) demand and output. (2) Cheaper loans reduce firms' costs of production, which can lower cost-push inflation and encourage firms to expand and hire. (3) The currency may weaken, making exports cheaper abroad and stimulating external demand.
Why lower interest rates may not succeed: (1) If households and firms are pessimistic, they may not borrow or spend even when rates fall. (2) Cutting rates raises consumer spending and reduces saving, which increases total (aggregate) demand and can push up demand-pull inflation rather than reducing it. (3) If rates are already near zero (the liquidity trap), further cuts have little effect.
Watch out: for a question about whether a cut reduces inflation, the "why it will not" side is actually that lower rates can increase spending and therefore demand-pull inflation — this is the counterargument, not a reversal of the "will reduce" points. Keep both chains of reasoning distinct.
