ACC518 - Positive Accounting Theory
Main summary
Key takeaways
Main ideas / concepts conveyed
-
Purpose of Positive Accounting Theory (PAT)
- PAT aims to explain why accounting outcomes happen and predict what accounting choices managers/accountants are likely to make in given circumstances.
- It is contrasted with normative (prescriptive) accounting theories, which tell managers/accountants what they should do.
-
Positive vs. normative theories
- Positive theories:
- Explain/predict behavior (“why something happens”).
- Do not instruct managers what to do.
- Predict which accounting methods managers are likely to select under certain incentives/constraints.
- Normative theories:
- Are prescriptive (“what should be done”).
- Have a historical basis (as referenced by the lecturer, though details aren’t provided).
- Positive theories:
-
Core assumption behind PAT
- Individuals (managers) are assumed to act from self-interest / self-wealth maximization.
- The lecturer notes some real-world counterexamples (people may act nobly or for other goals), but PAT’s working assumption treats self-interest as dominant.
-
Why PAT is studied / where it shows up
- The lecturer frames PAT as observable in business life and everyday experience.
- Course relevance is tied to motivations and incentives shaping managers’ decisions.
-
Terminology confusion noted in the lecture
- “positive accounting theory” (lowercase) refers to a general type of positive theories.
- Positive Accounting Theory (capitalized) refers to a specific theory associated with Watts and Zimmerman.
- The capitalized name can be confusing because it overlaps with the general school of theories.
-
Underlying relationships PAT focuses on
- PAT emphasizes agency relationships:
- Owners (shareholders) delegate decision-making to managers/agents.
- Owners do not fully trust managers to act solely for the firm’s interests, so they monitor/control them.
- Agency monitoring tools and mechanisms:
- Monitoring (including financial reporting and audits)
- Bonding: contractual arrangements meant to align manager actions with owner expectations
- Agency costs, including unavoidable residual loss (managers can still act opportunistically)
- PAT emphasizes agency relationships:
-
Efficient Markets Hypothesis link
- PAT is described as evolving from the efficient markets hypothesis:
- Share prices react to information (e.g., earnings announcements).
- Ball & Brown (1968) is used as evidence:
- Positive earnings announcements → share price rises
- Negative earnings announcements → share price falls
- Key limitation:
- This market-reaction evidence shows earnings matter, but it doesn’t explain why specific accounting methods are chosen—that’s where PAT’s incentive/contract focus comes in.
- PAT is described as evolving from the efficient markets hypothesis:
Methodology / structure (the “hypotheses” PAT uses)
PAT’s framework, as described, contains three main hypotheses. Each predicts what accounting method a manager may select based on incentives and pressures.
1) Bonus Plan Hypothesis (Management Compensation Hypothesis)
-
Main prediction
- Managers in firms with bonus plans are more likely to choose accounting methods that increase current-period reported income.
-
Rationale (incentive mechanism)
- Bonuses are assumed to increase the manager’s self-interest payoff (higher personal compensation).
-
Likely accounting behavior
- Choose accounting methods that make the firm look more profitable in the bonus-relevant period.
-
Examples of opportunistic timing/manipulation
- If managers won’t reach a bonus threshold, they may shift earnings to a future period (e.g., delaying recognition of invoices until after period end).
-
Empirical support described
- Evidence suggests managers manage earnings to maximize bonuses, including shifting income across periods.
-
Observed behavioral consequence
- Incentives can create short-term focus over long-term value creation.
-
Additional examples given
- Managers nearing retirement may be less likely to fund long-term R&D when compensation is tied to near-term accounting performance measures.
2) Debt Hypothesis (Agency Costs of Debt)
-
Main prediction
- The higher the firm’s debt-to-equity ratio / leverage, the more likely managers are to use accounting methods that increase reported income.
-
Rationale (debt contract constraints)
- Debt contracts (bank loans) often include constraints (e.g., covenants) tested with accounting numbers.
- Managers benefit if results avoid covenant violations, helping preserve access to financing.
-
Likely accounting behavior
- Manipulate/report in ways that keep key ratios within covenant limits.
- Use discretion in accruals and accounting choices.
-
Concept of incentive over time
- Incentive to manipulate increases as the firm approaches covenant breach.
-
Other related pressures
- Risk and interest rates can be linked:
- Higher risk may mean higher interest rates.
- Managers may try to appear less risky to negotiate better terms.
- Risk and interest rates can be linked:
-
Empirical support described
- References include research such as “Lell and Loer and Martin” and a “CTer in 98” citation (as stated) about leverage covenants and accounting manipulation near thresholds.
-
Examples of covenant measures mentioned
- Debt-to-assets
- Interest coverage
- Current ratio
- Coverage/threshold ranges (including interest coverage requirements, as described)
3) Political Cost Hypothesis
-
Main prediction
- Larger firms (size) face more political attention (“political cost” pressure), leading managers to reduce reported profits to lessen scrutiny.
-
Proxy variable
- Firm size is treated as a proxy for political attention.
-
Why political attention matters
- Scrutiny from governments, lobby groups, collective action, and public opinion can lead to:
- Higher taxes
- Wage claims/product boycotts
- Regulatory changes (e.g., “super profits tax” style policies)
- Scrutiny from governments, lobby groups, collective action, and public opinion can lead to:
-
Likely accounting behavior
- Use accounting methods that reduce profits to lower political pressure.
-
Illustrative examples mentioned
- Shell example: large profits with minimal Australian tax due to transfer pricing leads to senate inquiry and potential regulatory/tax changes—PAT predicts managers would reduce reported profits/accounting-managed figures.
-
Lobby group mechanism
- Political costs are not only government-driven:
- Interest groups can pool resources to investigate more effectively than individuals.
- Representatives may act to maximize constituents’ welfare, influencing corporate outcomes.
- Political costs are not only government-driven:
Usefulness and limitations / criticisms of PAT
-
No direct prescription
- PAT does not tell managers which accounting method to use; it predicts likely choices.
-
Not value-free in practice
- Criticism: PAT is based on an overly negative/simplistic view of humans as purely self-interested.
-
Limited development / dated evidence
- The lecture suggests that empirical/theoretical development hasn’t advanced much, implying older research dominance.
-
Limits of large-scale empirical research
- Much research uses broad capital market data (e.g., share price reactions), which may:
- Ignore organizational-specific relationships
- Ignore how internal structures (owners/managers/debt holders/political connections) drive behavior more directly than market-wide patterns.
- Much research uses broad capital market data (e.g., share price reactions), which may:
-
How this affects interpretation
- Share price reactions to earnings announcements may not fully capture the managerial incentives shaping accounting-method selection.
