Business growth changes scale and can occur internally or through integration.
Must know
- Organic growth expands existing operations.
- Horizontal integration combines rivals.
- Vertical and conglomerate integration involve different relationships.
Must know definitions
Small and medium-sized enterprise (SME): a business within the relevant country or institution’s size thresholds; definitions vary.
Large corporation: a business above the relevant SME size thresholds; compare measures such as employees, turnover or capital employed.
Organic growth: internal growth funded by reinvested profits or borrowing, without merging with another firm.
Forward vertical integration: merging with a firm closer to the customer in the supply chain.
Backward vertical integration: merging with a firm further from the customer in the supply chain.
Horizontal integration: merging with a firm at the same stage of production in the same industry.
Conglomerate integration: merging with a firm in a different, unrelated industry.
Diseconomies of scale: rising long-run average costs as a firm grows too large to manage efficiently.
Demerger: splitting a business into separate, independent businesses; this need not involve selling the separated business.
Explain and apply
Mechanism in brief: Horizontal integration can increase scale and market share; vertical integration can coordinate adjacent production stages. Each may reduce costs, but organisational disruption and weaker competitive pressure can offset savings.
Distinguish: Organic growth can use borrowing; growth does not guarantee lower average cost.
Use the extract: Identify what each firm did before integration, the financing method and the likely cost savings.
The size of businesses
- The size of a business is usually measured by its number of employees.
- An SME is a small or medium-sized enterprise. Employee, turnover and asset thresholds differ between countries and institutions; use the definition supplied in the question rather than treating one cut-off as universal.
- A large corporation operates on a scale above the relevant SME definition; size can also be compared using turnover, capital employed or market share.
- Other measures — turnover, market share, or capital employed — can also indicate size, but employee count is the standard measure at this level.
How businesses grow
- Businesses can grow either internally or by combining with other firms.
- Organic growth is where a business grows internally by reinvesting profits or borrowing from banks, rather than merging with another firm.
Reasons for organic growth
increasing market share, developing new innovative products, finding new markets for existing products, encouraging existing customers to buy more through advertising, or investing in new capital and technology to expand production.
Apple's growth through the development of new products such as the iPhone and iPad, funded largely by reinvested profits, is a widely cited example of organic growth.
Organic growth may avoid merger integration problems and let existing owners retain control, but it is not necessarily self-funded or debt-free: firms may finance it through borrowing, retained profits or new equity. Its speed and risk depend on the project and financing.
Inorganic growth happens through merging with or acquiring another firm, and takes several forms depending on where in the supply chain the two firms sit:
| Type of integration | Definition | Example |
|---|---|---|
| Forward vertical integration | Firm merges with another firm closer to the customer (later stage of production) | A coffee producer buying a café chain |
| Backward vertical integration | Firm merges with another firm further from the customer (earlier stage of production) | A car manufacturer buying a tyre manufacturer |
| Horizontal integration | Two firms at the same stage of production, in the same industry, merge | Virgin Money and Northern Rock; Amazon and LoveFilm |
| Conglomerate integration | Two firms in different, unrelated industries merge | A diversified group acquiring a business in an unrelated industry; the classification depends on the activities of the two businesses being combined. |
Advantages and disadvantages of each type of merger/takeover
- Vertical integration (forward or backward) gives a firm greater control over its supply chain, which can reduce costs, improve quality control, and secure better access to raw materials or distribution outlets.
Disadvantage
the merging firms often have different organisational cultures, which can cause internal conflict, and the combined firm may suffer diseconomies of scale as it becomes harder to manage and coordinate.
vertical integration → control over supply chain ↑ → costs ↓, quality control ↑, input access secured
Horizontal integration allows firms to benefit from economies of scale, spread risk across a larger asset base, rationalise duplicate operations (e.g. closing overlapping branches), and reduce the intensity of competition in the market.
Its disadvantages mirror vertical integration
cultural clashes between merging firms and the risk of diseconomies of scale from managing a larger, more complex organisation.
Conglomerate integration allows a firm to reduce risk by operating across different, unrelated markets, and to benefit from knowledge transfer between markets.
However, it requires managing very different skill sets across industries, does not necessarily generate economies of scale (since the firms operate in unrelated markets), and can suffer from cultural differences between the businesses involved.
| Type | Key advantages | Key disadvantages |
|---|---|---|
| Vertical | Supply chain control, lower costs, secure raw materials | Cultural clashes, diseconomies of scale |
| Horizontal | Economies of scale, risk spreading, rationalisation, less competition | Cultural clashes, diseconomies of scale |
| Conglomerate | Risk reduction via diversification, cross-market knowledge | Needs different skills, no guaranteed economies of scale, cultural difference |
Constraints on business growth
A firm's growth can be limited by several factors
The size of the market places a ceiling on growth — a firm serving a small or niche market has less room to expand than one in a mass market.
Limited access to finance constrains growth because smaller or newer firms are often seen by banks as riskier and struggle to borrow on favourable terms, especially since the financial crisis increased banks' risk-aversion.
Owner objectives matter too
an owner focused on philanthropy, work-life balance, or maintaining full personal control may deliberately choose not to expand, even where growth is possible.
Regulation (e.g. environmental rules, licensing requirements, high corporation tax) raises the cost of expansion and can discourage firms from growing further.
Reasons some firms remain small and others grow
- Some firms remain small because of the constraints above, or because they operate successfully as niche market monopolists — a small firm serving a narrow, specialised market (e.g. an independent local café with a loyal customer base) may face relatively price-inelastic demand and limited competitive pressure, so there is little incentive to expand and risk diseconomies of scale.
Other firms grow deliberately to
benefit from economies of scale (falling long-run average costs as output rises, e.g. bulk-buying discounts on raw materials),
increase market share, or
gain monopoly power that allows greater control over price — as seen in many of the horizontal and conglomerate mergers described above.
Impact of growth of firms on businesses, workers and consumers
| Stakeholder | Positive impact of growth | Negative impact of growth |
|---|---|---|
| Businesses | Market share ↑, economies of scale, higher profits | Risk of diseconomies of scale |
| Workers | Job security ↑ (larger firms often more stable), possible higher wages if firm more profitable | Increased mechanisation may reduce jobs/security |
| Consumers | Lower prices if economies of scale are passed on | Higher prices if firm gains monopoly power |
Demergers
- A demerger is when a business separates one or more of its divisions into independent businesses. This need not involve selling the separated business.
Firms demerge for several reasons
to resolve cultural differences between merged divisions,
to create more focused firms that concentrate on their core business,
to protect the value of a firm (e.g. separating a loss-making division),
to reduce the risk of diseconomies of scale,
to raise money through asset sales, or
to satisfy the requirements of competition authorities.
Examples
the Foster's Group demerging its wine and beer divisions, and Lloyds TSB Banking Group demerging into two separate banks — TSB and Lloyds Bank.
demerger → firm separates a division into an independent business → remaining business more focused → easier to manage → diseconomies of scale risk ↓
| Stakeholder | Impact of demerger |
|---|---|
| Businesses | Greater focus may improve performance; funds are raised only if the separation involves a sale. The effect also depends on which activities are retained. |
| Workers | A clearer business focus may support jobs, but restructuring can also involve redundancies or weaker job security. |
| Consumers | Independent firms may compete more strongly and better meet consumer needs; prices and quality depend on the resulting market structure and efficiency. |
Cost reductions benefit consumers only if passed on through price, quality or investment. Judge the source of savings and remaining competitive pressure rather than assuming that larger size is efficient.
Rapid recap
Organic growth expands existing operations; integration combines businesses. Classify a merger using the firms' relationship before integration, not their names or financing method.
Diagram cue: use LRAC only if economies of scale are central.
