PROFIT MAXIMISATION

Profit maximisation → Marginal Cost(MC) : Marginal Revenue (MR)

Profit maximization occurs at MC = MR because:

  • Marginal Cost (MC) is the cost of producing one more unit.
  • Marginal Revenue (MR) is the revenue gained from selling one more unit.
  • If MR > MC, the firm should produce more to increase profit since they are earning a profit on each unit.
  • If MC > MR, the firm is producing too much and should cut back to avoid losses.
  • When MC = MR, the firm is at the most profitable output level—producing more or less would reduce profit.

Generally we assume all firms are profit maximisers.

Benefits

  • More dynamic efficiency → higher profits allow for greater investment in innovation → improved product quality, technology, Economies of Scale (EOS), and workforce training.
  • Greater market power → firms can gain a competitive edge (e.g., bulk buying advantages).
  • Shareholder satisfaction → higher profits lead to higher dividends and greater investment appeal.
  • Higher wages for staff → helps retain skilled workers → increases productivity → lowers costs → improves product quality and consumer satisfaction → strengthens brand loyalty.
  • Investment in automation → replaces low-quality labor, improving efficiency.
  • Business survival and growth → enhances confidence in the firm and industry.

Costs

  • Risk of monopoly formation → if profits are too high, competition weakens, allowing the firm to charge higher prices and exploit consumers, reducing consumer welfare and surplus.
  • Difficult to determine the exact profit-maximizing point → firms may struggle to precisely identify where MC = MR, as calculating the cost of producing an extra unit can be complex, costly, and time-consuming.
  • Attracting new competitors → high profits may invite new entrants that undercut prices, depending on the barriers to entry.
  • Multi-product businesses face complexity → constantly adjusting to changing consumer preferences is challenging and stressful, leading to higher labour turnover → increases redundancy and retraining costs, causing inefficiency.
  • Regulatory scrutiny → substantial supernormal profits can attract the Competition & Markets Authority (CMA), which aims to protect consumers and ensure fair competition. If a firm is suspected of anti-competitive behavior, the CMA may investigate:
    • Scrutiny can damage public image, reducing sales and market share.
    • Investigations increase costs and delays, harming productivity and competitiveness.
  • Principal-agent problem → Managers may not always aim for profit maximization, leading to inefficiency, low morale, and higher managerial turnover, potentially benefiting rival firms.

Revenue Maximization

  • Revenue Maximization: MR = 0
  • Firms often lower prices to increase revenue and quantity sold.
  • This expansion in production can lead to Economies of Scale (EOS), reducing long-run (LR) average costs, enabling even lower prices over time.
  • A firm may gain market power and evolve into a monopoly in the long run.
  • Lower prices help firms:
    • Gain market share
    • Build brand loyalty
    • Attract customers before shifting to profit maximization

Reasons for Revenue Maximization:

  • Small firm size
  • Lack of market share
  • Industry characteristics i.e. dominant firms in the market they cannot compete with.
  • Market contestability
  • Regulatory environment

(Yes i know it doesnt say the pros and cons in the spec, however these points ive provided below are valuable in understanding how beneficial it is for firms to lower prices and can be applied to various parts of the specification)

Advantages of Revenue Maximisation

  • Lower prices → attract customers (benefiting low-income households) → increase sales → build brand loyalty → gain market share → more market power → potential monopoly in the long run → achieve Economies of Scale (EOS) → raise barriers to entry (lower contestability) → dictate prices and profit maximize in the long run.
  • Lower prices & higher quantity → increase consumer choice + benefit low-income households who otherwise cannot afford these goods → reduce equity issues and better meet consumer preferences → improve welfare and boost allocative efficiency.
  • Firms lower prices to boost revenue and sales. This can lead to EOS as output expands → lower long-run average costs (LRAC) → even lower long-run prices → potential monopoly formation.
  • Predatory pricing: Firms can undercut competitors, driving them out of the market. This benefits consumers short-term (lower prices), but in the long run, fewer competitors may give the firm greater power to exploit consumers with higher prices.

Disadvantages of Revenue Maximisation

  • Lower prices may not always attract new customers as demand also depends on product quality.
  • The firm may lack dynamic efficiency because it is not profit-maximizing → fewer supernormal profits → less investment in innovation and product improvement → lower sales → consumers may be worse off → reduced consumer welfare and weaker brand loyalty.
  • Lack of profits can lead to poor quality, fewer sales, and potentially lower market share.
  • Depends on the firm and industry: Cutting prices may not always increase customers if competitors (especially monopolies) have strong brand loyalty and dominant market positions.

SALES MAXIMISATION

This occurs where AR:AC, in other words the firm is only earning normal profit (0 profit). The pros and cons of revenue maximisation apply here as they are very similar since the firm is cutting prices to boost sales usually.

PRACTICE ESSAY QUESTION

‘Revenue maximisation is a better business objective than profit maximisation for many businesses’. To what extent do you agree with this statement? Refer to an industry of your choice.

The way i would structure this:

  • Mini introduction with definitions.
  • Paragraph 1--> Why revenue maximisation is a better business objective (pro)
  • Paragraph 2 --> Evaluation of why revenue maximisation is not better (cost)
  • Paragraph 3 --> Why profit maximisation is a better business objective (pro)
  • Paragraph 4 --> Why profit maximisation is not a better business objective (cost)
  • Final Paragraph (EVALUATION) --> giving my judgement which will include how revenue maximisation is a great short run objective as it can help a firm gain brand loyalty, power and EOS. In the long run, when it is established with strong market share, it can raise prices and profit maximise.
