Essay questions on production, costs and revenue
Examiner insight
- What to cover
- Technological progress raises productivity, which lowers unit costs and can shift LRAC down. It can improve productive and dynamic efficiency.
- Watch out
- Cover productivity, efficiency and costs, as the question asks.
Examiner insight
- What to cover
- Economies of scale (technical, purchasing, financial, managerial) lower long-run average costs as output rises. Diseconomies (communication, coordination, motivation) raise them beyond the minimum efficient scale.
- Watch out
- Use real examples for each type.
Examiner insight
- What to cover
- Internal economies: technical, purchasing, financial, managerial. External economies: skilled labour, infrastructure, suppliers.
- Watch out
- External economies shift the whole LRAC curve down, not along it.
Examiner insight
- What to cover
- Short run: stay open if price covers average variable cost. Long run: exit if price is below average total cost.
- Watch out
- The AVC rule is the key mark. Many answers only mention profit.
Examiner insight
- What to cover
- Profit plays three roles. It signals where consumers want resources to go, it gives firms an incentive to supply and innovate, and it is a source of finance for investment. Losses signal that resources should leave an industry.
- Watch out
- Link profit to the signalling, incentive and rationing functions of the price mechanism.
Examiner insight
- What to cover
- Low profit can result from poor management (X-inefficiency, high costs).
- Watch out
- Use theory of firms' objectives. Answers that just list causes of low profit stay mid-level.
Data response questions on production, costs and revenue
Context 2: The UK water industry
Examiner insight
- What to cover
- A large minimum efficient scale means only a few firms can produce at the lowest cost. If MES is large relative to market demand, the market supports only a few large firms or a monopoly.
- Watch out
- Show MES on the diagram and link it to market structure.
Context 2: Coffee
Context 2: Eye care in the UK
Context 2: Drones

Context 1: Water

Examiner insight
- What to cover
- A natural monopoly has large economies of scale. Splitting it removes those economies, so long-run average costs rise.
- Watch out
- Show on the diagram why one firm has the lowest average cost.
Context 1: Palm oil
Context 1: Competition in UK Banking
Examiner insight
- What to cover
- Lower barriers let new banks enter. Supply rises, price falls, supernormal profit is competed away to normal profit.
- Watch out
- End clearly at normal profit where AR = AC.
Context 1: Privatisation of Royal Mail
Context 1: Supermarkets
