Context 1
Free school meals
Extracts: Index of average household disposable income, and index of · The rising cost of food · There’s no such thing as a free lunch
TopicMarket failure and government interventionExternalities
Calculate the income elasticity of demand for food if an increase in income from £25 000 to £30 000 leads to an increase in the quantity demanded of food of 10%.
TopicPrice determination in a competitive marketIncome elasticity
TopicPrice determination in a competitive marketDemand & supply
Draw a supply and demand diagram showing the effects of an increase in income on the price and quantity sold of an inferior good.
TopicPrice determination in a competitive marketDemand & supplyIncome elasticity
Explain two possible reasons, other than a change in income, for the rise in the price of food over the period shown.
TopicPrice determination in a competitive marketDemand & supply
Examiner insight
- What to cover
- Two reasons from the supply side or other demand factors: higher costs (energy, fertiliser), poor harvests, higher world demand, weaker pound.
- Diagram
- Supply shifting left, or demand shifting right.
- Watch out
- The question excludes income, so do not use it.
Using the data in the extracts and your economic knowledge, assess whether the government should provide free school meals for all, some or no school children.
TopicMarket failure and government interventionMerit & demerit goodsGovernment intervention (micro)Inequality & poverty
Examiner insight
- What to cover
- Free school meals are a merit good with external benefits (better concentration, health and attainment) and help reduce inequality.
- Diagram
- Merit good diagram showing under-consumption without intervention.
- Evaluation
- Consider cost, opportunity cost, targeting (means-tested versus universal), stigma and take-up. Judge between all, some or no children.
- Watch out
- Consider all three options before you conclude.
Context 2
Commodity prices
Extracts: Average monthly world prices of potash and crude oil, · Competition in the potash market · Commodities markets: should governments intervene?
TopicMarket structuresMonopoly & market power
Calculate the price elasticity of demand for potash if this fall in price leads to an increase in the quantity demanded of 10%.

TopicPrice determination in a competitive marketCommodity markets
Explain the possible effects on the market for wheat of a fall in the price of a fertiliser such as potash.
TopicPrice determination in a competitive marketCommodity markets
Examiner insight
- What to cover
- Potash is a fertiliser, so a lower price reduces wheat farmers' costs. Supply of wheat shifts right, the price of wheat falls and quantity rises.
- Diagram
- Wheat market with supply shifting right.
- Watch out
- Explain the link between the two markets clearly.
Using the data in the extracts and your economic knowledge, assess whether market forces should be left to determine the price of commodities such as potash, oil and gas.
TopicPrice determination in a competitive marketCommodity markets
Examiner insight
- What to cover
- Market forces set prices through supply and demand and signal scarcity.
- Diagram
- Demand and supply diagram, or buffer stock diagram.
- Evaluation
- Commodity prices are volatile because supply and demand are price inelastic; market power (potash) and externalities (oil and gas) also cause failure. Judge using the extract data.
- Watch out
- Use potash, oil and gas from the extracts.
- Aaverage cost falls due to the growth of a firm.
- Baverage cost rises due to a firm reducing its output.
- Ctotal cost rises due to the growth of a firm.
- Daverage cost rises due to the growth of a firm.
Show the answer
The answer is D.
TopicProduction, costs and revenueCosts & economies of scale

- Aan increase in the quantity of frozen peas supplied.
- Ban increase in the price of frozen peas.
- Ca change in consumer preference for frozen peas.
- Da decrease in the price of a substitute for frozen peas.
