1. The Economic Problem, Demand and Supply
AQA content 1 to 3 (Paper 1 and Paper 3). Scarcity and opportunity cost, production possibility diagrams, rational and behavioural decision making, demand, supply, elasticities and how markets set prices and allocate resources.
Key facts
- The economic problem: needs and wants are unlimited but resources (land, labour, capital, enterprise) are scarce, so every choice has an opportunity cost: the next best alternative given up.
- A production possibility frontier (PPF) shows the maximum combinations of two goods an economy can make. Points inside show unemployed resources; an outward shift shows economic growth; a curved PPF shows rising opportunity cost.
- Positive statements can be tested against facts; normative statements are value judgements, often containing 'should' or 'ought'.
- Behavioural economics challenges the rational consumer: bounded rationality, bounded self-control, biases (rules of thumb, anchoring, social norms) and the importance of fairness. Policy uses choice architecture, framing, nudges, default choices and restricted choice.
- A change in a good's own price causes a movement along the demand or supply curve; a change in any other factor (income, tastes, price of related goods, costs, technology, taxes and subsidies) shifts the whole curve.
- Price elasticity of demand (PED) = %ΔQd ÷ %ΔP. Inelastic if between 0 and −1, elastic if beyond −1. If demand is inelastic, a price rise increases total revenue.
- Income elasticity (YED) = %ΔQd ÷ %ΔY: positive for normal goods (above +1 for luxuries), negative for inferior goods. Cross elasticity (XED) = %ΔQd of good A ÷ %ΔP of good B: positive for substitutes, negative for complements. Price elasticity of supply (PES) = %ΔQs ÷ %ΔP.
- The price mechanism has three functions: signalling, incentive (rationing) and allocative. Consumer surplus is the area below demand and above price; producer surplus is the area above supply and below price.
Flashcards
Exam tip: Always state the sign and size of an elasticity and interpret it. 'PED = −0.5, so demand is price inelastic and a price rise raises revenue' scores more than the number alone.
2. Production, Costs and Market Structures
AQA content 4 and 5. Productivity, short-run and long-run costs, economies of scale, revenue and profit, then perfect competition, monopolistic competition, oligopoly, monopoly, price discrimination and contestable markets.
Key facts
- The law of diminishing marginal returns: in the short run, adding more of a variable factor to a fixed factor eventually makes marginal product fall, so marginal cost rises.
- Costs: TC = TFC + TVC; ATC = TC ÷ Q; MC = change in TC from one more unit. MC cuts ATC and AVC at their minimum points.
- Economies of scale (technical, purchasing, managerial, financial, risk-bearing) lower long-run average cost; diseconomies (coordination, communication, motivation) raise it. Minimum efficient scale is where LRAC first reaches its lowest point.
- Profit maximisation is at MC = MR. Normal profit is included in costs (TR = TC); supernormal profit is any profit above that. Revenue maximisation is at MR = 0; sales maximisation is at AC = AR.
- Perfect competition: many firms, identical products, perfect information, free entry and exit. Firms are price takers; supernormal profit is competed away in the long run, giving allocative (P = MC) and productive (minimum ATC) efficiency.
- Monopoly: a single seller (legal monopoly 25% market share in the UK). Higher price and lower output than competition, deadweight loss, but possible dynamic efficiency and economies of scale. Price discrimination needs market power, separable markets and different PEDs.
- Oligopoly: a few interdependent firms, high concentration ratio, barriers to entry. Can be collusive (cartels, illegal in the UK) or competitive; game theory and the kinked demand curve explain price rigidity and non-price competition.
- Contestable markets have low barriers to entry and no sunk costs, so even a monopoly may be forced to price close to the competitive level by the threat of hit-and-run entry.
Flashcards
Exam tip: Draw cost and revenue diagrams in a fixed order: MC, AC, AR, MR, then find MC = MR and go up to AR for price. Shade profit as (AR − AC) × Q.
3. Labour Markets and Inequality
AQA content 6 and 7. Demand for labour as derived demand, MRP theory, labour supply, wage determination, monopsony, trade unions, the national minimum wage, and the distribution of income and wealth, poverty and inequality.
Key facts
- Demand for labour is derived demand: it depends on demand for the product. In a competitive market the demand curve is the marginal revenue product (MRP) curve: MRP = MPP × MR.
- Elasticity of demand for labour is higher when labour costs are a large share of total costs, when labour is easy to replace with capital, and when product demand is elastic.
- Labour supply depends on the wage, non-monetary benefits, qualifications needed and the size of the working population. A rising wage gives substitution and income effects for individuals.
- Wage differentials arise from different MRP, skills, training costs, trade union power, discrimination and immobility of labour (geographical and occupational).
- Monopsony: a single dominant employer pays a lower wage and employs fewer workers than a competitive market. A trade union or a minimum wage can raise both wages and employment in a monopsony.
- A national minimum wage set above the equilibrium in a competitive market can cause unemployment if labour demand is elastic; the effect is smaller if demand is inelastic or employers have monopsony power.
- Income is a flow; wealth is a stock. The Lorenz curve shows distribution; the Gini coefficient runs from 0 (perfect equality) to 1 (perfect inequality).
- Absolute poverty means not having enough for basic needs; relative poverty in the UK is often defined as household income below 60% of the median. Policies include progressive taxes, benefits, minimum wages and education.
Flashcards
Exam tip: For any minimum wage question, ask: competitive market or monopsony? The answer changes the conclusion, which is exactly the kind of evaluation examiners reward.

4. Market Failure and Government Intervention
AQA content 8. Public goods, externalities, merit and demerit goods, information gaps, monopoly as market failure, and government tools: taxes, subsidies, price controls, regulation, state provision, tradable permits, and government failure.
Key facts
- Market failure is when the price mechanism allocates resources inefficiently. Complete failure: a missing market (public goods). Partial failure: a market exists but gives the wrong quantity or price.
- Public goods are non-rival and non-excludable, so the free-rider problem means they are under-provided or not provided at all, for example street lighting and national defence.
Flashcards
Exam tip: Label externality diagrams with MPC, MSC, MPB and MSB, mark both quantities and shade the welfare loss triangle pointing towards the social optimum.
5. Measuring the Macroeconomy and AD/AS
AQA content 9 and 10. Macroeconomic objectives, index numbers, real and nominal values, the circular flow, aggregate demand and aggregate supply, the multiplier and the accelerator.
Key facts
- Main objectives: sustainable economic growth, low unemployment, low and stable inflation (UK CPI target 2%), balance of payments equilibrium, plus fiscal and environmental aims.
- Index numbers: index = (value ÷ base-year value) × 100. Percentage change between two index numbers = (new − old) ÷ old × 100, not the simple difference in points.
Flashcards
Exam tip: Percentage change and points change in index numbers are a classic trap. From 120 to 126 is 6 points but a 5% rise.
6. Growth, Unemployment and Inflation
AQA content 11. The economic cycle, output gaps, causes and effects of growth, types of unemployment, causes and effects of inflation and deflation, the Phillips curve and conflicts between objectives.
Key facts
- Short-run growth is an increase in real GDP (actual growth); long-run growth is an increase in productive potential (LRAS or PPF shifting out).
- The economic cycle: boom, downturn, recession (two consecutive quarters of negative real GDP growth) and recovery. A positive output gap means actual output is above potential; a negative gap means below.
Flashcards
Exam tip: Identify the type of unemployment or inflation from the cause in the question, then match the policy: supply-side policy for structural, demand management for cyclical.
7. Monetary, Fiscal and Supply-Side Policy
AQA content 12 and 13. Money, banks and financial markets, the Bank of England and monetary policy including quantitative easing, regulation of the financial system, fiscal policy, the budget, national debt, and supply-side policies.
Key facts
- Functions of money: medium of exchange, store of value, measure of value (unit of account), method of deferred payment. Commercial banks create credit; the Bank of England is the central bank.
- The Monetary Policy Committee sets Bank Rate to meet the 2% CPI target. A rise in Bank Rate tends to reduce consumption and investment, appreciate the pound and so lower AD and inflation, with time lags.
Flashcards
Exam tip: For any policy, give the full chain of reasoning (transmission mechanism) and then evaluate with time lags, the size of the output gap and side effects.
8. The International Economy
AQA content 14. Globalisation, comparative advantage and trade, protectionism, trading blocs and the WTO, the balance of payments, exchange rate systems, and economic development.
Key facts
- Absolute advantage: producing more with the same resources. Comparative advantage: producing at a lower opportunity cost. Trade benefits both countries if they specialise by comparative advantage.
- Protectionism: tariffs, quotas, subsidies to domestic firms and non-tariff barriers. A tariff raises the domestic price, cuts imports, raises domestic output and creates deadweight losses.
Flashcards
Exam tip: In comparative advantage questions, work out the opportunity cost of one unit of each good for each country before choosing. Absolute advantage is a common distractor.
How to pass
- AQA gives you 120 minutes for 80 marks, so 1 minute 30 seconds per mark. A 25-mark essay deserves about 35 minutes including planning; do not let a 9-mark question eat that time.
- Draw a diagram whenever it helps your analysis: label both axes, every curve and both equilibria, and refer to the diagram in your writing. An unexplained diagram earns little.
- Show your working in calculations. Percentage change = (new − old) ÷ old × 100; elasticity = % change in quantity ÷ % change in the variable. A points change in an index number is not a percentage change.
- Evaluation (AO4) separates the top grades: weigh up short run versus long run, the size of elasticities, time lags and the assumptions in the data, then reach a supported judgement.
- In the AQA Paper 3 multiple-choice section, sketch quick diagrams on the question paper and check the units in every calculation before choosing an option.
