What is meant by diseconomies of scale?

Increases in average cost per unit that occur when a business grows beyond the size it can manage efficiently.

Distinguish between internal and external economies of scale.

Internal economies arise from the growth of the individual firm, while external economies arise from the growth of the industry or region and are available to every firm in it.

Explain purchasing economies of scale.

A larger firm orders in greater quantities, so suppliers grant bulk discounts and the cost of each unit of material falls.

Explain technical economies of scale.

Large-scale output justifies specialised, high-capacity machinery whose cost is spread over so many units that the cost per unit falls.

Explain financial economies of scale.

A large firm is treated as a lower credit risk and can borrow larger sums, so it obtains finance at a lower rate of interest than a small firm can.
