Economies of scale

  • As a business grows, it can increase its scale of output generating efficiencies that lower its average costs (cost per unit) of production

    • These efficiencies are called economies of scale

    • Economies of scale help large firms to lower their costs of production beyond what small firms can achieve

Economies of scale

Graph showing long-run average cost curve, illustrating economies of scale, lowest average cost at productive efficiency, and diseconomies of scale.
Economies of scale occur when average costs decrease with increasing output and diseconomies of scale occur when average costs increase with increasing output
  • With relatively low levels of output, the businesses' average costs are high

  • As the business increases its output, it begins to benefit from economies of scale, which lower the average cost per unit

  • At some level of output, a business will not be able to reduce costs any further

    • This point is called productive efficiency

  • Beyond this level of output, the average cost will begin to rise as a result of diseconomies of scale

Types of economies of scale

  • Internal economies of scale occur as a result of the growth in the scale of production within the business

    • The firm can benefit from lower average costs (AC) generated by factors from inside the business

Types of internal economies of scale

Type

Explanation

Managerial economies

  • Occurs when large firms can employ specialist managers who are more efficient at certain tasks and this efficiency lowers the average cost

  • Managers in small firms often have to fulfil multiple roles and are less specialised

Marketing economies

  • Large firms spread the cost of advertising over a large number of sales and this reduces the AC

  • They can also reuse marketing materials in different geographic regions, which further lowers the average cost

Purchasing economies

  • Occur when large firms buy raw materials in greater volumes

  • They are likely to receive a bulk purchase discount, which lowers the average cost

Technical economies

  • Occur as a firm can use its machinery at a higher level of capacity due to the increased output

  • This spreads the cost of machinery over more units and lowering the average cost

Risk bearing economies

  • Occur when a firm can spread the risk of failure by increasing its numbers of products

  • Greater product diversification is likely to lead to a lower failure rate, lowering the average cost

Diseconomies of scale

  • Diseconomies of scale occur when a company grows too large, making it difficult to manage and control its operations

    • It may face challenges in coordinating its various departments, managing its workforce, or maintaining quality control

    • The cost per unit increases as a result of these inefficiencies

Common diseconomies of scale

Diseconomies

Explanation

Management diseconomies

  • Occur when managers work more in their self interest than in the interest of the firm

    • E.g. Managers become territorial and obstructive, thus reducing efficiency and increasing the average cost

Communication diseconomies

  • Occur when a firm's organisational structure becomes more complex with multiple layers of management, resulting in communication difficulties

  • This leads to slow responses and increased average costs

Geographical diseconomies

  • Occur when a firm has widespread bases of operations across multiple geographic locations 

  • This leads to logistical and communication challenges which can raise average costs

Cultural diseconomies

  • Occur when a firm expands into foreign markets in which workers have very different work or productivity norms

  • Particularly during the early stages of expansion, this leads to production disruption which can raise average costs

Managing diseconomies of scale

  • A business can manage or reduce diseconomies of scale in a range of ways

  1. Decentralise decision-making

    • By organising operations into divisions or profit centres, each with its own managers and targets, the business can speed up decisions

  2. Invest in communication systems

    • Planning software can give managers instant access to data from across the firm

    • Clear, shared information reduces coordination errors and prevents the slow communication that often increase overhead costs.

  3. Strengthen employee motivation and culture

    • Introducing schemes such as performance-related pay, team-based goals, flexible working and regular feedback sessions keeps staff engaged in a large organisation

    • Higher motivation lowers absenteeism and labour turnover, helping the business maintain productivity even as the workforce grows

Economies of scope

  • Economies of scope occur when it is cheaper, on average, for one firm to produce a range of different goods or services together than to make each of them in separate, stand-alone businesses

  • Savings come from sharing resources such as buildings, distribution networks, research teams or marketing across several products

Examples of economies of scope

Company

Explanation

Disney

  • The same characters and stories feed films, Disney+ streaming, theme parks, toys and clothing

  • One creative idea pays for itself many times across different business lines, lowering the average cost of each product

Amazon

  • A single website, payment system and logistics network handles everything from books to garden furniture

  • Those shared assets spread fixed costs over many revenue streams

Synergy

  • Synergy is the extra value created when two businesses combine their resources so that the joint result is greater than the sum of what each could achieve alone

    • The gain might come from lower costs (cost synergies) or from higher sales (revenue or product synergies)

Examples of synergies

Example

Synergies

Explanation

Microsoft and LinkedIn

  • Cost savings and extra sales

  • Microsoft shares information from Outlook, Teams and other programs with LinkedIn, making those products more useful and easier to sell

  • The two firms also share offices and support staff, which cuts day-to-day costs

Disney and 21st Century Fox

  • Bigger content library and lower costs

  • Disney adds Fox movies and TV shows to Disney+ and its theme parks, attracting more viewers and visitors

  • Using the same studios and marketing teams for both sets of films saves money

  • However, synergies may be difficult to establish and maintain for several reasons

    • Cultural clashes

      • Synergy relies on people sharing ideas, data and resources

      • If the two workforces have very different ways of working, they may resist sharing or simply misunderstand each other

      • Projects may stall and expected savings may never materialise

    • Integration costs

      • Bringing systems, brands or supply chains together often costs more than projected

      • New IT links, training, redundancy payments and legal fees can spiral, reducing cost savings or extra sales that were expected

Overtrading

  • Overtrading happens when a business tries to grow faster than its working capital resources can support

    • It may accept more orders than it can manage, open sites by borrowing heavily or take over other businesses without careful evaluation

  • Cash is tied up in stock or unpaid invoices, but wages, suppliers and interest must still be paid on time

  • The result is a cash flow squeeze that can force the firm to borrow at high cost, sell assets in a hurry or, in extreme cases, fail

Recent examples of overtrading

Carillion Plc

Covivilaity Plc

Text reads "Conviviality Plc" in two styles; "Conviviality" in bold black font, and "Plc" in smaller, lighter grey font.
  • The construction company signed many large contracts with payment terms stretching beyond 120 days

  • Up-front costs on these projects drained cash faster than income arrived, creating a severe cash flow problem

  • It entered liquidation in 2018 , owing £7 billion with only £29 million in cash

  • Between 2013 and 2017 the drinks wholesaler/retailer bought several rivals, pushing annual sales above £1.6 billion but stretching its cash flow

  • A surprise £30 million tax bill in early 2018 could not be paid, and the company entered administration within weeks

Ways to avoid overtrading

  1. Cash-flow planning

    • If the cash flow forecast shows a future shortage, the business should slow its growth by delaying opening a site, ordering less stock, or postponing recruitment

  2. Arrange short-term finance as a safety net

    • A business could look to secure an overdraft or short-term loan before taking on large new orders

    • With credit already approved, the business can cover wages and materials even when customers pay later than expected

  3. Tighten cash control

    • Bring cash in faster by issuing invoices promptly, chasing late payments and asking for deposits on large jobs

    • Delay cash outflows by negotiating longer payment terms with suppliers and leasing expensive equipment instead of buying it outright

    • Hold less stock by placing smaller, more frequent orders so less money is tied up in inventory
