21  Objectives of business firms

21.1 What Does a Firm Maximise?

The conventional answer is profit maximisation. But twentieth-century writers — Baumol, Marris, Williamson, Cyert and March, Simon — produced a wave of alternative theories in which the firm pursues sales, growth, managerial utility, satisficing behaviour or stakeholder welfare instead of pure profit. Modern finance offers a fifth answer — shareholder wealth (value) maximisation — which has displaced profit maximisation as the dominant normative goal. The right answer depends on ownership, managerial discretion, market structure and information.

21.2 Profit Maximisation — The Classical Goal

The neoclassical theory of the firm (Marshall, 1890; Robbins, 1932) assumes the firm chooses output where Marginal Revenue = Marginal Cost and the second-order condition (MC cutting MR from below) is satisfied. The implicit owner is the entrepreneur who bears risk and claims residual profit.

21.2.1 Arguments For

TipArguments For Profit Maximisation
  • Simple, measurable — a single objective makes optimisation tractable.
  • Survival — without profit, firms exit in competitive markets.
  • Reward for risk — profit is the entrepreneur’s incentive.
  • Resource allocation — profits guide resources to most-valued uses.
  • Basis for taxation, dividends, growth and reinvestment.

21.2.2 Arguments Against

TipLimitations of Profit Maximisation
  • Vague — short-term or long-term? Accounting or economic profit?
  • Ignores risk and uncertainty — same expected profit, different risk.
  • Ignores time value of money — when does the profit arrive?
  • Ignores stakeholders — customers, employees, society.
  • Inconsistent with the separation of ownership and control in modern corporations.

21.3 Shareholder Wealth Maximisation

Modern corporate finance (Solomon 1963; Modigliani & Miller; Fama) prescribes maximisation of shareholder wealth — proxied by the market value of the firm’s equity. It corrects three weaknesses of profit maximisation:

TipWealth vs Profit Maximisation
Dimension Profit Maximisation Wealth Maximisation
Measure Accounting profit Market value of equity
Time horizon Often short-term Long-term cash flows
Treatment of risk Ignored Discounted via cost of capital
Treatment of time Ignored Time value of money applied
Universally accepted? Increasingly disputed Dominant in modern corporate finance

The wealth-maximisation goal is operationalised through NPV-positive investment decisions, optimal capital structure, dividend policy and risk management.

21.4 Sales Maximisation — Baumol (1959)

William J. Baumol in Business Behaviour, Value and Growth (1959) argued that managers of large modern firms (with diffuse shareholders) actually maximise sales revenue, subject to a minimum profit constraint acceptable to shareholders.

TipBaumol’s Sales Maximisation
  • Why sales? Managerial salaries, prestige, market share and bank credit all correlate more strongly with sales than with profit.
  • Profit acts as a constraint, not the maximand.
  • Output under Baumol’s model is higher, and price lower, than under profit maximisation.
  • Promotional / advertising expenditure is also higher.

21.5 Growth Maximisation — Marris (1964)

Robin Marris in The Economic Theory of Managerial Capitalism (1964) argued the modern firm maximises the balanced rate of growth — the simultaneous growth of demand for products and supply of capital, subject to a security constraint (avoidance of takeover).

TipMarris’s Growth Model — Key Elements
  • Managers prefer growth (more salary, status, power).
  • Shareholders prefer a high valuation ratio (market value / book value).
  • Conflict resolved by the takeover threat — too low a valuation invites raiders.
  • The firm grows so as to satisfy the valuation constraint.

21.6 Managerial Utility Maximisation — Williamson (1963)

Oliver E. Williamson in Managerial Discretion Theory (1963) modelled the manager as maximising a utility function that includes:

TipWilliamson’s Managerial Utility Function
  • S = expenditure on staff (managerial slack).
  • M = managerial emoluments (perks).
  • I_D = discretionary investment (pet projects).
  • Subject to a minimum acceptable profit constraint.

The model explains managerial slack in firms where shareholders cannot fully monitor managers — central to the agency problem literature.

21.7 Satisficing — Simon (1959), Cyert and March (1963)

Herbert Simon (Nobel laureate 1978) and later Richard Cyert and James March (in A Behavioral Theory of the Firm, 1963) replaced maximising behaviour with satisficing — firms set aspiration levels on several objectives and choose actions that satisfy minimum thresholds across all.

TipCyert and March — Behavioral Theory
  • Firms are coalitions of stakeholders with conflicting goals.
  • Conflicts resolved through side payments, standard operating procedures and organisational slack.
  • Goals are multiple — profit, sales, market share, inventory, production targets.
  • Aspiration levels adjust with experience.
  • Bounded rationality — managers cannot calculate all options; they search until “good enough”.

21.8 Stakeholder Theory

R. Edward Freeman in Strategic Management: A Stakeholder Approach (1984) argued that firms should serve all stakeholders — shareholders, employees, customers, suppliers, community, government. Each has a legitimate stake in the firm’s success. The Business Roundtable (USA, 2019) re-endorsed this view — pivoting away from the Friedman doctrine of shareholder primacy.

TipFriedman vs Freeman
View Position
Friedman (1970) “The social responsibility of business is to increase its profits”
Freeman (1984) Firms should serve all stakeholders with legitimate interests

21.9 Other Objectives

TipOther Firm-Level Objectives
  • Long-run survival — Galbraith, Rothschild.
  • Market share — common in business plans.
  • Customer satisfaction — total-quality movement.
  • Social responsibility — CSR, sustainability, ESG.
  • Risk minimisation — risk-averse owners.
  • Employee welfare — labour-managed firms (e.g., cooperatives).
  • Multi-objective / hierarchy — most firms have multiple objectives, with trade-offs.

21.10 The Agency Problem

Modern theory of the firm (Jensen and Meckling, 1976) identifies the agency problem — divergence between the interests of owners (principals) and managers (agents). The firm spends agency costs:

TipThree Types of Agency Cost
  • Monitoring costs by principals (audits, board oversight).
  • Bonding costs by agents (incentive contracts).
  • Residual loss — the welfare loss from imperfect alignment.

Mechanisms to reduce agency costs include stock options, performance pay, independent directors, takeover threat, debt discipline (Jensen’s free cash flow theory).

  • DP = MR
View solution
Correct Option: B
**MR = MC** (first-order) with MC cutting MR from below (second-order).

View solution
Correct Option: A
Wealth maximisation incorporates risk via cost of capital and time via discounting.

In Marris's growth model, the *security constraint* arises from:

  • AGovernment regulation
  • BTakeover threat from raiders
  • CBank credit limits
  • DTrade-union pressure

21.12 Quick Recall

ImportantQuick recall
  • Profit maximisation — neoclassical; MR = MC. Limits: ignores risk, time, stakeholders.
  • Shareholder wealth maximisation — modern finance; market value of equity; NPV-positive.
  • Baumol (1959) — sales-revenue maximisation s.t. min profit.
  • Marris (1964) — balanced growth s.t. takeover-induced security (valuation) constraint.
  • Williamson (1963) — managerial utility U = f(Staff, Managerial emoluments, Discretionary investment) s.t. profit constraint.
  • Simon (1959) + Cyert & March (1963) — bounded rationality, satisficing; coalition with side payments, SOPs, organisational slack.
  • Freeman (1984) — stakeholder theory; vs Friedman (1970) — shareholder primacy. Business Roundtable 2019 endorsed stakeholders.
  • Jensen & Meckling (1976) — agency theory; agency cost = monitoring + bonding + residual loss.
  • Other goals: survival (Rothschild, Galbraith), market share, customer satisfaction, CSR, risk minimisation.
