Growth and Survival of Firms: The Business Life Cycle

Hello future economists! This chapter moves us away from abstract market theory and into the fascinating, real-world dynamics of business. We are exploring how firms grow (or fail to grow), the strategies they use to expand their power, and the internal conflicts that can arise within them. This knowledge is essential for understanding market structures and business objectives, which are crucial A-Level topics.

Don't worry if some of the business terminology seems new—we will break down the complex types of growth and corporate conflicts into simple, manageable steps!

1. Reasons for Different Sizes of Firms (7.7.1)

Why is a local bakery small, but a company like Toyota huge? The size a firm achieves depends on several key factors:

A. Nature of the Industry
  • Minimum Efficient Scale (MES): This is the lowest level of output at which Long-Run Average Cost (LRAC) is minimised.
    If the MES is high (like in car manufacturing or utilities), the industry naturally favours large firms. If the MES is low (like hairdressing), small firms can survive easily.
  • Barriers to Entry: Industries with high barriers (patents, massive start-up costs) tend to foster large, established firms.
B. Demand Factors
  • Size of the Market: A firm catering to a niche, local market (e.g., specialised vintage clothing) will likely remain small. A firm serving a global market (e.g., smartphone producer) must be large to meet demand.
  • Ability to Exploit Economies of Scale: Only large firms can fully utilise technical, managerial, and financial economies of scale (EOS) to lower costs and dominate the market.
C. Owner's Preferences
  • Risk Tolerance: Some owners prefer to keep their operations small to retain maximum control, limit financial risk, or maintain a personal touch with customers, even if it means sacrificing higher profit.
  • Profit vs. Control: As a firm grows, owners often have to give up control to external investors (shareholders) or managers. Many prefer to keep the firm small to avoid this dilution of control.

The size is a balance between the potential cost advantages of being large (EOS) and the strategic choices made by the owners based on market size and risk.

2. How Firms Achieve Growth (7.7.2 & 7.7.3)

Firms generally use two methods to expand their productive capacity and market share: internal growth (slow and steady) and external growth (fast and aggressive).

A. Internal Growth (Organic Growth)

Internal growth means the firm expands its own scale of operations, often by reinvesting retained profits.

  • Methods: Increasing output capacity, investing in new capital, opening new branches, expanding R&D, and increasing staff.
  • Pros: It is slower, but often more stable, less risky, and easier to manage as the firm integrates new operations gradually.
  • Diversification: A form of internal growth where a firm expands its product range or moves into different markets (e.g., a sports shoe company starts producing athletic apparel). This spreads risk.
B. External Growth (Integration)

External growth involves combining with or taking over another firm. This is usually achieved through mergers (two firms agree to combine) or takeovers (one firm buys a controlling interest in another). This process is known as integration.

Don't worry, the names of the integration types are logical! Think about the stages of production.

Three Types of Integration:
  1. Horizontal Integration:
    A merger between firms operating at the same stage of production in the same industry.
    Example: Two rival supermarket chains merge.
    Goal: Increase market share, benefit from larger economies of scale, and reduce competition.
  2. Vertical Integration:
    A merger between firms at different stages of production in the same industry.
    • Backward Vertical Integration: Merging with a firm that supplies inputs (closer to the raw material stage).
      Example: A bakery buys a wheat farm.
      Goal: Secure reliable supply, control quality, and potentially reduce input costs.
    • Forward Vertical Integration: Merging with a firm that sells the output (closer to the consumer stage).
      Example: A bakery buys a chain of coffee shops to sell its bread.
      Goal: Control distribution channels, secure outlets, and capture the retailer's profit margin.
  3. Conglomerate Integration:
    A merger between firms in completely unrelated industries.
    Example: A shoe manufacturer buys an insurance company.
    Goal: Spread risks across different industries and utilise the financial resources of the parent company.
C. Reasons and Consequences of Integration (7.7.3)

Mergers are complex strategic moves. They are undertaken for potential gains but carry serious risks.

Reasons for Integration (Why firms merge):
  • Economies of Scale (Horizontal/Vertical): The new, larger firm can access technical, financial, and marketing advantages.
  • Increased Market Power (Horizontal): Dominating the market allows the firm to become a price maker (monopoly power).
  • Synergy: The idea that the combined entity is worth more than the sum of its parts (1 + 1 = 3). Cost savings, shared technology, and combined market knowledge lead to greater efficiency.
  • Securing Supply/Distribution (Vertical): Reducing uncertainty about future costs or sales.
  • Risk Spreading (Conglomerate): If one industry suffers a downturn, profits from the unrelated industry can stabilise the firm.
Consequences of Integration:
  • Higher Prices/Less Choice: Especially after horizontal integration, less competition leads to higher prices for consumers and reduced innovation.
  • Job Losses: Duplicated roles (like two HR departments) are often cut to achieve cost savings.
  • Diseconomies of Scale (DoS): The sheer size of the integrated firm can lead to communication problems, bureaucracy, and poor decision-making, increasing average costs.
  • Conflict of Corporate Cultures: Trying to merge two previously independent companies can lead to internal disputes and inefficiency.
Quick Review: Growth Methods
  • Internal: Slow, stable, low risk.
  • External (M&A): Fast, high risk, high reward potential.
  • Remember HVC: Horizontal (Same stage), Vertical (Different stages), Conglomerate (Unrelated).

3. The Principal-Agent Problem (7.7.5)

In most large firms, there is a separation between ownership and control. This separation leads directly to the Principal-Agent Problem.

  • The Principal: The owners of the firm (shareholders). Their main goal is typically profit maximisation.
  • The Agent: The people hired by the principals to run the firm on a daily basis (managers/directors).

The problem arises because the agent (manager) may pursue goals that benefit themselves, rather than strictly benefiting the principal (shareholder).

Why Do Objectives Differ?
  • Shareholders (Principals) want: Maximum long-run profit, leading to higher dividends and stock value.
  • Managers (Agents) might want:
    • Sales Maximisation: High sales increase market dominance and prestige (and often lead to higher managerial bonuses and salaries).
    • Profit Satisficing: Achieving just enough profit to keep the shareholders happy, while using spare time and resources to pursue non-financial goals (e.g., better work-life balance, high-status projects).
    • Growth Maximisation: Increasing the size of the firm quickly to lead to higher personal status and power.

Think of it this way: If you hire someone to mow your lawn (you are the principal), you want them to do the fastest, most efficient job possible. The worker (agent) might be tempted to stretch the job out to fill their required time slot or use a slower, more comfortable mower, even if it delays things. Their goals are not perfectly aligned with yours!

To combat this, shareholders often offer performance-related pay (like bonuses tied to profit or stock options) to incentivise managers to act in the owners' interest.

4. Cartels and Collusion (7.7.4)

Sometimes, firms decide that competing is too costly, so they engage in collusion—secret agreements to restrict competition. A cartel is the formal structure of this agreement.

A. Definition and Conditions

A Cartel is a group of independent firms that agree to act together as a monopoly to restrict output, raise prices, and increase industry profits. Cartels are generally illegal under anti-trust laws in most countries.

Conditions Necessary for an Effective Cartel:
  1. Few Firms: The fewer the firms involved, the easier it is to negotiate and monitor the agreement.
  2. Homogeneous Product: If the product is identical (e.g., crude oil, cement), consumers cannot easily switch between firms based on quality, making the price restriction effective.
  3. High Barriers to Entry: New firms entering the market would break the cartel's control over supply.
  4. Stable Demand: If demand is predictable and relatively price inelastic, firms can confidently set high prices without fearing a large loss in sales.
  5. Effective Punishment: Members must have a credible mechanism to punish firms that cheat (over-produce).
B. Consequences of a Cartel
  • For Consumers: Higher prices and lower output (just like a monopoly), leading to a reduction in consumer surplus and overall welfare loss.
  • For Firms (Members): Cartels aim for higher profits, but they are inherently unstable.
    There is a huge incentive for individual firms to cheat: if one firm secretly increases its output above the agreed quota, it benefits from the high cartel price but sells a larger volume, gaining huge temporary profit. This cheating destabilises the entire agreement.
  • For Society: Misallocation of resources (allocative inefficiency) because P > MC.

Did you know? The most famous example of a cartel is OPEC (Organization of the Petroleum Exporting Countries), which controls a large portion of the world’s oil supply. While it operates legally internationally, its function is purely to coordinate output quotas to maintain high oil prices.

Quick Review: Cartels & Agents
  • Cartel: Firms collude to act like a monopoly. Unstable due to the incentive to cheat.
  • Principal-Agent: Conflict of interest between owners (Principals, wanting profit) and managers (Agents, often wanting sales/power).
