Describe internal and external economies of scale.

Internal economies of scale refer to cost savings achieved by a firm as it grows and increases production:

• These savings can include purchasing economies, where discounts are negotiated due to larger order sizes.
• Technical economies arise from using larger-scale machinery or equipment, which increases efficiency.
• Management economies occur when specialist staff, like accountants, streamline operations and reduce costs.
• Financial economies result from a firm being viewed as more credit-worthy by banks, leading to lower interest rates.
• Risk-bearing economies involve diversifying into different goods or services to reduce the risk of failure.

External economies of scale are cost savings achieved by an entire industry or group of firms:

• These savings can result from the increased size of the industry, allowing for lower average costs.
• Local colleges providing relevant training reduce costs associated with skilled workforce development.
• Ancillary firms locating near industry clusters can offer specialised goods or services at lower costs.
• Agglomeration economies occur when firms in related industries benefit from sharing resources and knowledge.
• Transportation infrastructure improvements by local authorities reduce logistics costs and improve efficiency.
