Lessons
AS micro, AS macro and A2 micro, each in the order it is taught. 59 of 59 lessons are open.
AS micro: markets and government intervention
The nature of economics4 lessons, in this order
- 01The economic problem and PPFsScarcity, choice and opportunity cost, the factors of production, and how a PPF shows efficient, inefficient and unattainable output and rising opportunity cost.
- 02PPF shifts and economic growthWhat shifts a PPF outwards or inwards, biased shifts, actual versus potential growth, and capital goods against consumer goods.
- 03Positive and normative economicsTelling testable statements from value judgements, through the minimum wage debate, and why the difference matters for policy.
- 04Specialisation, the division of labour and moneyWhy splitting production into tasks raises productivity, its costs, how specialisation leads to trade, and the functions of money.
Demand6 lessons, in this order
- 05Demand: movements and shiftsThe demand curve, extensions and contractions along it, and the conditions of demand that shift it: income, substitutes, complements, tastes, population and more.
- 06Price elasticity of demand: calculating and interpretingThe PED formula, percentage changes from the old value, what a figure such as −0.4 means, and using PED to predict sales and spending.
- 07PED on a diagramElastic, inelastic, perfectly elastic, perfectly inelastic and unitary demand curves, and why PED changes along a straight line.
- 08What affects PEDSubstitutes, necessity, addiction, brand loyalty, share of income, time and how widely the good is defined, and how to use them in an answer.
- 09PED and total revenueWhy a price cut raises total revenue when demand is elastic and lowers it when demand is inelastic, with the revenue rectangles. Through Debenhams.
- 10Income and cross elasticity of demandCalculating and interpreting YED (normal, inferior, luxury, necessity) and XED (substitutes and complements), and why firms care.
Supply2 lessons, in this order
- 11Supply: movements and shiftsWhy the supply curve slopes up, extensions and contractions along it, and the conditions of supply that shift it. Through the 2024 cocoa harvest.
- 12Price elasticity of supplyCalculating PES, what elastic and inelastic supply look like, the straight-line rule, and why supply is more elastic in the long run. Through olive oil.
The price mechanism2 lessons, in this order
- 13Price determination and market shiftsHow supply and demand set the equilibrium price, how shortages and surpluses push the price there, what happens when one or both curves shift, and the three functions of price.
- 14Consumer and producer surplusWhat the two surpluses measure, where they are on the diagram, how to calculate them, and how they change when demand or supply shifts. Through the Oasis ticket sale.
Indirect taxes and subsidies4 lessons, in this order
- 15Indirect taxes: specific taxesWhy a specific tax shifts supply up by the tax, why the price rises by less than the tax, and how to show revenue, who pays and the deadweight loss.
- 16Tax incidence and elasticityWho really pays an indirect tax: why the more inelastic side of the market bears more of it, with the extremes and the calculations.
- 17Ad valorem taxesWhy a percentage tax such as VAT pivots supply, with the gap widening as price rises, and how to work VAT out in both directions.
- 18SubsidiesSupply shifts down by the subsidy: who gains, what it costs the government, the welfare loss, and whether a subsidy is worth it.
Market failure7 lessons, in this order
- 19Negative externalitiesExternal costs, MPC and MSC, why the free market over-produces goods that pollute, and the welfare loss triangle. Through Lough Neagh.
- 20Correcting negative externalitiesA tax equal to the external cost, tradable permits, regulation and minimum prices: how each works and how well. Through Northern Ireland’s carrier bag levy.
- 21Positive externalitiesExternal benefits, MPB and MSB, why merit goods such as vaccinations are under-consumed, the welfare loss, and subsidies and state provision. Through measles.
- 22Public goodsNon-rival and non-excludable goods, the free-rider problem, why a market may provide none at all, quasi-public goods, and government provision.
- 23Information gapsImperfect and asymmetric information, over-consumption of demerit goods, under-consumption of merit goods, and how governments respond. Through the ban on disposable vapes.
- 24Maximum and minimum pricesHow a maximum price below equilibrium causes a shortage and a minimum price above it a surplus, who gains and loses, and when they are worth it. Through Scotland’s rent freeze.
- 25Government failureWhen intervention makes things worse: subsidies or taxes set wrongly, distorted price signals, unintended consequences and administrative costs. Through Northern Ireland’s Renewable Heat Incentive.
AS macro: the national economy
How the economy works5 lessons, in this order
- 26The circular flow of incomeHow income flows between households and firms, injections and withdrawals, and why national income changes when they are unequal. Through saving in 2020.
- 27Aggregate demandThe components of AD, C + I + G + (X − M), why the AD curve slopes down and what shifts it. Through the collapse in spending in 2020.
- 28The multiplierWhy an injection raises national income by more than itself, calculating the multiplier from the MPC or MPW and what limits it.
- 29Short-run and long-run aggregate supplyWhat SRAS is and why costs shift it, what LRAS shows about productive capacity and the classical and Keynesian views. Through the 2022 energy shock.
- 30Equilibrium and the AD/AS modelMacroeconomic equilibrium, output gaps, demand-pull and cost-push inflation and supply-side growth, with AD and AS together.
Measuring economic performance3 lessons, in this order
- 31Macroeconomic objectives and how they are measuredGrowth, inflation, unemployment and the current account; real GDP, GDP per head and PPP; recessions and output gaps; the HDI and the limits of GDP.

- 35Monetary policyThe Bank of England, the MPC and the 2% target; Bank Rate and quantitative easing; the transmission mechanism, real interest rates and the limits of monetary policy.
- 36Supply-side policiesMarket-based and interventionist policies to raise productive capacity and shift LRAS: productivity, incentives, training and infrastructure and their strengths and weaknesses.
- 37Conflicts between macroeconomic objectivesTrade-offs between objectives: inflation and unemployment on the short-run Phillips curve, growth and the current account, the environment, equality and the national debt.

- 51Barriers to entry and contestabilityEconomies of scale as a barrier, limit pricing, structural and strategic barriers, and the threat of entry.
- 52Contestability and hit-and-run entryWhy the threat of entry can keep even a monopolist’s price close to average cost, what makes a market contestable, and why perfect contestability is rare.

For students
Daily retrieval
Questions come back when you are about to forget them: tomorrow, then in three days, a week, a fortnight. What you know stays secure. What you leave fades, and Review shows you where.
For teachers

Tick the topics your class has covered and get a retrieval starter that mixes last lesson, last week and older topics. Project it, reveal the answers, or print it.
Built on what the evidence says works
Retrieval before re-reading
Every lesson opens with a question, and the ones you get wrong come back later.
Worked examples that fade
The first time, the diagram is drawn for you. By the end of the lesson you draw it alone.
You do the marking
A model answer and the mark scheme levels, not a score from a machine. No streaks, no leaderboards.
