Essay questions on production, costs and revenue

Explain, using examples, how the existence of economies and diseconomies of scale affect firms’ average costs of production.

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.
Explain the factors a profit-maximising firm will take into account when deciding whether to shut down or to carry on operating, both in the short run and in the long run.

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.
Explain the role of profit in a market economy.

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.

Data response questions on production, costs and revenue

Context 2: The UK water industry

Extract E (line 10) states: ‘The minimum efficient scale in the water industry is large’. With the help of a diagram, explain why the large minimum efficient scale in the water industry is likely to lead to the market being supplied by a few large firms with monopoly power.

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: Drones

Extract F (lines 10–12) states: ‘The total cost of a delivery consists of £150 for the drone and another £350 to carry out the whole operation. The drone carries food weighing 110 pounds (50 kilos), enough for 50 people for a day.’ Calculate the average total cost of delivering food weighing one pound. Give your answer to the nearest penny.

Context 2: The British railway system

Extract E (lines 10–11) describes the British railway sector as a ‘natural monopoly’, which was split up into ‘no less than 100 pieces’ when it was privatised. With the help of a diagram, explain why breaking up a natural monopoly in rail may affect long-run average costs.

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

Extract B (lines 15–16) states: ‘Another important reason for the increased popularity of palm oil with growers is that it is the most productive oil crop...’ If 4 hectares of land yield 15 tonnes of palm oil, calculate, to one decimal place, the expected yield of sunflower oil from 6 hectares of land.

Context 1: Competition in UK Banking

Extract C (lines 10–11) states that ‘There is ample opportunity for new players to enter the sector.’ With the help of a diagram, explain how the lowering of barriers to entry in the banking market might lead to lower prices and a situation in which banks make normal profit.

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.
