3.2.1 Business Objectives

Edexcel A-Level Economics (9EC0) | Theme 3.2.1

Specification Coverage: Edexcel unit 3.2.1 - Business Objectives. Students should be able to understand and explain the difference between profit maximisation, revenue maximisation, sales maximisation, and satisficing, apply the rules used to identify each objective on a firm diagram, and analyse how the principal-agent problem can cause firms to pursue objectives other than profit maximisation.

Profit Maximisation

Assumed objective: In traditional theory, firms are assumed to aim for profit maximisation.

Rule: Profit is maximised where \( MC = MR \).

Why? This maximises returns for shareholders through dividends and higher share prices.

Revenue Maximisation

Objective: Maximise total revenue.

Why? Firms may want to increase market share, benefit from economies of scale, or reflect incentives created by the principal-agent problem, such as sales managers being paid commission.

Rule: Revenue is maximised where \( MR = 0 \).

On the same diagram, this gives an output of Qrm and a lower price Prm. It also shows that \( Qrm > Qpm \) and \( Prm < Ppm \), so profit is lower than under profit maximisation.

Sales Maximisation

Objective: Maximise the quantity of units sold.

Why? Firms may want to clear stock, dominate the market, or meet sales targets.

Rule: Sales maximisation occurs where \( AC = AR \), so the firm breaks even and earns only normal profit.

On the same diagram, this gives output Qsm, where \( Qsm > Qrm > Qpm \), and the price Psm is the lowest of the three.

Satisficing

Objective: Aim for a satisfactory level of profit rather than the maximum possible profit.

Why? This often arises because of the principal-agent problem, where managers may pursue their own goals, such as an easier life or higher sales for prestige, instead of shareholder objectives.

Result: Output and price are likely to lie between the profit maximisation and sales maximisation points.

Summary of Objectives

Objective Rule Price Output Reason
Profit Maximisation \( MC = MR \) Highest Lowest Shareholder returns.
Revenue Maximisation \( MR = 0 \) Medium Medium Market share and manager incentives.
Sales Maximisation \( AC = AR \) Lowest Highest Market dominance and stock clearance.

Exam Preparation

  • Draw one firm diagram showing AR, MR, AC, and MC, and identify the output level for each objective.
  • Explain the rationale behind each objective rather than just memorising the rule.
  • Understand the principal-agent problem as a major reason why firms may not profit maximise.
  • Compare the likely effects on price, output, and profit under each objective.
