Topic Synopsis
This topic explores the various objectives firms may pursue beyond simple profit maximisation, including revenue maximisation, sales maximisation, and satisficing, and the theoretical models used to represent these goals.
Key Concepts & Core Principles
- Profit maximisation: Occurs where marginal cost (MC) = marginal revenue (MR). This is the traditional assumption for firms in perfect competition and is used to determine optimal output and price. Supernormal profit is earned when AR > AC at this output.
- Revenue maximisation: Occurs where marginal revenue (MR) = 0. Firms aiming to maximise total revenue will produce more than profit-maximising output, leading to lower prices. This is common in firms with high fixed costs (e.g., airlines) or those seeking to increase market share.
- Sales maximisation: Occurs where average revenue (AR) = average cost (AC), i.e., normal profit is made. The firm produces the maximum output without making a loss. This objective is often pursued by managers who want to increase sales volume (and possibly their own bonuses) while still covering costs.
- Satisficing: When managers aim for a satisfactory level of profit rather than maximum profit, often to keep shareholders content while pursuing other goals (e.g., growth, market share, or managerial perks). This arises due to the principal-agent problem and asymmetric information.
- Principal-agent problem: A conflict of interest between owners (principals) and managers (agents). Managers may pursue objectives that benefit themselves (e.g., higher salaries, prestige) rather than maximising shareholder value. Solutions include performance-related pay and shareholder monitoring.
Exam Tips & Revision Strategies
- Ensure you can draw and label the profit, revenue, and sales maximisation points on a standard firm diagram
- Be prepared to discuss why a firm might choose to sacrifice short-term profit for long-term growth or market share
- Practice calculating the output levels for different objectives using provided cost and revenue data
Common Misconceptions & Mistakes to Avoid
- Confusing the conditions for revenue maximisation (MR=0) with profit maximisation (MC=MR)
- Failing to correctly label axes on diagrams for different objectives
- Inability to explain the rationale behind satisficing
- Misinterpreting the relationship between sales maximisation and average cost
Examiner Marking Points
- Identification of profit maximisation (MC=MR)
- Identification of revenue maximisation (MR=0)
- Identification of sales maximisation (AC=AR)
- Understanding of satisficing as a business objective
- Use of diagrams to illustrate different business objectives
- Explanation of why firms might choose objectives other than profit maximisation
