POSITIVE THEORY OF
Early demand for theory
• Capital markets research tried to explain
the effects of accounting
– was ultimately inconclusive and inconsistent
• mechanistic and no-effects hypotheses
• This research relied upon the EMH
– ultimately there were too many departures
• Led to the development of a positive
Early demand for theory
•
Positive theory incorporated a number
of observations
– many firms voluntarily provided
accounting reports
– firms lobbied in relation to accounting
standards
Contracting theory
•
The firm is seen as a ‘nexus’ of
contractual relationships
•
The firm is seen as an efficient way
of organising economic activity to
reduce contracting costs
– equity (management) contracts (an
Agency theory
• An agency contract is one where one party
(the principal) engages another (the agent) to act on their behalf
– e.g. where there is a separation of management
and ownership
• Both parties are utility maximisers
– agent may therefore act from self-interest
• divergence of interests is the agency problem – contracts incorporating accounting numbers can
Agency theory
•
The agency problem in turn gives
rise to agency costs spent to
overcome it
– monitoring costs – bonding costs
Agency theory
• Monitoring Costs – the cost of monitoring
the agent’s behaviour; initially borne by the principal but passed on to the agent through an adjustment to their remuneration (price protection)
• auditing costs, operating rules…
• Bonding Costs – the cost borne by the agent
as a result of them taking action to align their interests with those of the principal
• providing more regular financial reports (a cost
to the manager in terms of time and effort)
Agency theory
•
The agents incur bonding costs in
order to reduce the monitoring costs
they eventually bear
•
Agents stop spending on bonding
costs when the marginal cost equals
the marginal reduction in the
Agency theory
• Residual Loss – the loss associated with
not being able to fully align the interests of the agent with those of the principal
• Ex post settling up – (ex post = at the
end of each period)
– agent’s future remuneration based on
observed agent performance
– the principal changes the remuneration to be
Agency theory
• In the real world, price protection and
settling up are not perfect or complete
• Agents perceive that they will therefore not
be fully penalised for their divergent behaviour
• They have incentives to act opportunistically • This increases the residual loss
• This loss is borne by the principal as well as,
Agency theory
•
Agency theory attributes a role for
accounting
•
Accounting is part of the monitoring
and bonding mechanisms
•
Accounting numbers are used in
Price protection and
shareholder/manager agency
problems
•
The separation of ownership and
management leads to divergent
behaviour by agents
•
Divergence comes about because of
– the risk-aversion problem
Price protection and
shareholder/manager agency
problems
•
Risk aversion
– managers prefer less risk than do
shareholders
• different degrees of diversification affecting
risk
Price protection and
shareholder/manager agency
problems
•
Dividend-retention
– managers prefer to pay out less of the
profits as dividends than shareholders prefer
Price protection and
shareholder/manager agency
problems
•
Horizon
– managers have a shorter time horizon
with respect to their association with the firm than do shareholders
• shareholders are interested in future cash
flows
• managers have a time horizon only as long
Price protection and
shareholder/manager agency
problems
•
Contracting can be used to reduce
the severity of these problems
– manager remuneration is usually tied to firm
performance in some way to motivate
managers to act in the shareholders’ interest
• performance can be related to accounting numbers
such as sales, profits, return on assets, net asset growth, cash flow, etc
Shareholder-debtholder
agency problems
•
In this context, the manager is
assumed to be either the sole owner
of the firm, or has interests that are
totally aligned with the interests of
the shareholders
– the principal is the debtholder
– the agent is the manager acting on
Shareholder-debtholder
agency problems
•
Firm value is the value of debt plus
the value of equity
•
The value of equity can be increased
by
– either increasing the value of the firm
(efficient contracting); or
– transferring wealth away from
Shareholder-debtholder
agency problems
•
Varieties of opportunistic behaviour
– excessive dividend payments – asset substitution
Shareholder-debtholder
agency problems
•
Excessive dividend payments
– reduces the asset base securing the debt
– shareholders have received cash but limited
liability protects them from being personally liable for the debts of the firm in the event of bankruptcy
Shareholder-debtholder
agency problems
•
Asset substitution
– firm invests in higher risk projects to
benefit shareholders
• no benefit to debtholders
• but do share in possible losses
– shareholders are able to diversify and
have limited liability
Shareholder-debtholder
agency problems
•
Underinvestment
– in some circumstances, shareholders
have incentives not to undertake
positive NPV projects because to do so would increase the funds available to the debtholders but not to the
Shareholder-debtholder
agency problems
•
Claim dilution
– occurs when the firm issues debt of a
higher priority than the debt already on issue
– decreases the relative security and
Shareholder-debtholder
agency problems
•
Lenders will price protect
– through interest rates, the withholding
of funds and the length of the loan
•
The interests of shareholders can be
bonded to those of debtholders via
restrictions in lending agreements

Signalling theory
•
Managers voluntarily provide
information to investors - signals - to
assist in their decision making
•
Similar to efficient contracting
•
Aligned with the information hypothesis
•
Managers signal expectations and
intentions regarding the future
•
Incentives to signal good, neutral and
Political processes
•
Often firms try to avoid public
attention that is costly to them
– financially– in terms of public perception and
reputation
•
They reduce their reported profit or

•
Conservatism shows a bias by
accountants accelerating recognition
of expenses and decelerating
recognition of revenue

Additional empirical tests
of the theory
•
Evidence that managers use
accounting numbers to
– counter political pressure
– gain political advantages
– set management targets related to
remuneration
– minimise breaching debt covenants
– provide dividend constraints
Evaluating the theory
• Mixed support for positive accounting
theory
• Two categories of major criticism
– methodological and statistical criticism
• empirical evidence is weak and inconclusive
– philosophical criticism
• contrary to its claims, it is laden with value
judgments
• focuses on human behaviour and not the behaviour
Issues for auditors
•
The demand for auditing can be
explained by agency theory as part
of the monitoring and bonding
activity and costs
– higher quality auditors
Summary
• Positive accounting theory has been a major force in academic accounting research
• Incorporates a theoretical model of
contractual exchange between persons who use accounting numbers to effect their payoffs • Provides an explanation as to why accountants
account as they do
– minimises the cost of agency relationships
