This lesson explores agency theory as a foundational framework for understanding management accounting. It explains how agency theory addresses the conflicts of interest that arise from the separation of ownership and control, and how management accounting systems are designed to mitigate these incentive problems.

• Introduction to Agency Theory: Agency theory has been one of the most important theoretical paradigms in accounting during the last 25 years . It allows us to explicitly incorporate conflicts of interest, incentive problems, and mechanisms for controlling incentive problems into our models. This is important because much of the motivation for accounting has to do with the control of incentive problems .

• The Principal-Agent Relationship: In the simplest agency models, the organisation is reduced to two people: the principal and the agent. The principal’s roles are to supply capital, bear risk, and construct incentives, while the roles of the agent are to make decisions on the principal’s behalf and also to bear risk . Agency theory addresses two questions: how do features of information, accounting, and compensation systems affect (reduce or make worse) incentive problems, and how does the existence of incentive problems affect the design and structure of these systems ?

• Moral Hazard and Adverse Selection: Agency models capture incentive problems caused by two types of information asymmetry:

  • Moral hazard: The agent takes actions that are unobservable to the principal, potentially contrary to the principal’s interests.

  • Adverse selection: The agent has private information about their abilities or the environment that is not available to the principal .

• The Value of Accounting Information: For accounting information to have a role, it must be the case that incentive problems cannot be completely resolved via other means. The value of information is derived from the better decisions (and higher profits) that result from its use . Management accounting systems provide information that helps evaluate past decisions and improve future decisions, including resource allocation, coordination across subunits, pricing, costing, and compensation and incentives .

• Management Accounting and Agency Problems: Management accounting addresses agency problems through budgeting, product-costing systems, transfer pricing systems, valuation, and performance measurement (including both financial and non-financial measures) . By providing information that aligns the interests of management with those of shareholders, management accounting serves as a critical internal mechanism for controlling incentive problems.
