Reasons why firms grow

Firms expand their operations to achieve various objectives, which can be driven by financial goals or other motivations. Growth typically involves increasing output, either by scaling up production or by acquiring other businesses.

Motivations for business growth beyond profit

• Managerial objectives - Managers may seek expansion to increase their influence, secure higher salaries, or achieve personal career goals within a larger organisation.
• Status and prestige - Running a bigger firm can enhance the owner's or manager's reputation and social standing in the business community.

Benefits of business growth

Expanding a business can lead to several advantages, particularly in terms of efficiency, market position, and profitability.

Key advantages of expanding a business

• Achieving economies of scale - Growth allows firms to reach the minimum efficient scale (MES), where long-run average costs are at their lowest due to spreading fixed costs over more output.
• Increasing market share - A larger firm can reduce competition, potentially leading to greater market dominance.
• Gaining monopoly power - With reduced competition, firms may set higher prices and earn supernormal profits (profits above the normal level needed to keep the firm in business).
• Accessing new markets - Expansion can open up opportunities in international territories or new customer segments, diversifying revenue sources.

Internal (organic) growth

Internal growth, also known as organic growth, occurs when a firm expands using its own resources without involving other businesses. This approach focuses on building capacity from within.

How internal growth works

Firms increase their levels of factors of production, such as land, labour, capital, or enterprise, to boost output.

Examples of internal growth:

• Building new manufacturing facilities to increase production capacity.
• Hiring more workers to expand the workforce.
• Investing in additional resources, like raw materials or equipment.

Advantages of internal growth

• The firm retains full control over the growth process, allowing it to shape expansion exactly as desired.

Disadvantages of internal growth

• It is often a slow process, as building from within takes time.
• It can be expensive, requiring significant upfront investment without quick returns.

External (inorganic) growth

External growth, also referred to as inorganic growth, involves combining with other businesses to achieve rapid expansion. This method is typically faster than internal growth and can provide instant access to new capabilities.

Methods of external growth

• Takeovers - One firm purchases another, which then becomes part of the acquiring firm; the bought firm loses its independent identity.
• Mergers - Two firms combine to create a new, single company; this is often presented as a partnership of equals.

While the terms takeover and merger are sometimes used interchangeably, they have distinct legal differences: a takeover implies one firm dominating the other, whereas a merger suggests a mutual agreement to form a new entity.

Key features of external growth

External growth is usually quicker and can be cheaper than organic methods, as it avoids the need to build everything from scratch. It is an effective way to acquire expertise or enter new business areas rapidly.

Types of integration

• Horizontal integration - Combining with a firm at the same stage of production in the same industry, such as two competing retailers merging to increase market share.
• Vertical integration - Joining with a firm at a different stage of production in the same industry, either backwards (towards suppliers) or forwards (towards customers), to control the supply chain.
• Conglomerate integration - Merging with a firm in a completely different industry, to diversify operations and spread risk.
