How the economy works - AQA GCSE Economics (8136) module overview

How the economy works (subject content 3.2) is the macroeconomics half of AQA GCSE Economics (8136). It explains how the whole economy behaves, how government measures and manages it, and how it links to the rest of the world. It is examined in Paper 2: How the economy works. This page maps the unit and links to a focused answer for each dot point.

What this unit covers

The unit moves from the goals of policy, through the main indicators, to the tools and the global context.

• Economic objectives and GDP. The four macroeconomic objectives, what GDP measures, living standards and the conflicts between objectives.
• Economic growth. What growth is, its causes, the economic cycle, and the benefits and costs of growth.
• Employment and unemployment. How unemployment is measured, its types and causes, its costs, and full employment.
• Inflation. What inflation is, the CPI, demand-pull and cost-push causes, the effects, and deflation.
• Fiscal and monetary policy. Government spending and taxation, interest rates and the money supply, and the role of the Bank of England.
• The role of money and financial markets. Commercial banks, the central bank, financial markets, and how the sector supports households and firms.
• International trade and the global economy. Why countries trade, imports and exports, the balance of payments, and exchange rates.
• Globalisation. What globalisation is, its causes, the role of multinational companies, and its benefits and drawbacks.

The big ideas to hold together

• The four macroeconomic objectives (growth, low unemployment, low inflation, a sustainable balance of payments) often conflict, which drives evaluation questions.
• Policy comes in two kinds: fiscal (spending and tax) and monetary (interest rates and the money supply).
• The economy is open: trade, exchange rates and globalisation connect it to the rest of the world.

How to revise this unit

1. Learn the objectives and indicators. Know GDP, inflation (CPI), unemployment and the balance of payments precisely.
2. Separate fiscal from monetary policy. Know who controls each and how expansionary and contractionary policy work.
3. Build cause-and-effect chains. Extended answers reward developed reasoning (because, which means, leading to).
4. Practise data response and evaluation. Apply theory to real data and reach balanced, justified judgements.
