ItemThree essays on voluntary disclosures( 2018)This thesis consists of three distinct papers that examine different aspects of voluntary disclosure. In addition to contributing to the voluntary disclosure literature, this thesis also contributes to three other research areas: debt contracting, corporate governance and revenue-expense mismatching. Essay 1 tests the effects of voluntary and mandatory disclosure quality on the cost of public debt. Essay 2 tests the effects of audit committee oversight over management guidance. Essay 3 tests different explanations for why managers issue sales guidance.

ItemChoosing an auditor : corporate governance, interpersonal associations and investor confidence( 2000-06)This thesis provides evidence enabling an analysis of systemic director-auditor links, their nature, their determinants, their association with audit quality as an important component of corporate governance, and investor confidence in companies displaying these links. The motivation for examining interpersonal associations between directors and auditors comes from several sources. First is the observation that auditing is a knowledge-based service the quality of which is difficult to evaluate even after the product has been experienced, adding to the complexity of the purchasing decision (Murray 1991). The use of personal contacts to scan the business environment, disseminate information and reduce uncertainty is likely to assist that evaluation and so aid in auditor selection. One manifestation of these personal contacts is directors who hold directorships on more than one board, creating networks of ties between companies known as interlocking directorates. It tends to be non-executive or external directors who create these ties because they have more time to devote to multiple directorships. Interlocking directorates are a long-standing phenomenon that has been examined in the economics, organisational behaviour and sociology literatures and are argued to engender trust, and mediate transactions. Some countries restrict such directorate ties between industry competitors because of their potential to encourage collusion and competitive disadvantage but Australia has no such restrictions. In order to promote practice growth and firm survival, public accounting firms are known to tap into these networks, which often include former employees, encouraging personal contacts with, amongst others, directors of clients and potential clients. In this way, it is argued, companies interlocked through common directors tend to be audited by a common audit firm with the links extending to even audit partners. Extensive analysis of these interlocking directorates supports these arguments and finds that the association between interlocking directorates and director-auditor links becomes stronger as intra-industry and within confined geographical region data partitioning occurs and varies across audit firms. This variation across firms is subsequently used to model with some success auditor choice - even within the Big 6. Systematic ties between directors and audit firms and/or audit partners potentially threaten at least the appearance of auditor independence, if not the fact. On the other hand, following the DeAngelo (1981)auditor size argument, the potential loss of a ‘family’ of clients associated with a single director if audit quality is degraded may actually enhance audit quality. This thesis argues that directors value personal contact in auditor-client relationships but are aware of the potentially damaging connotations arising from such interpersonal associations and the potential for investor disquiet about them. Implicit in this argument is an assumption that investors are both interested and active in matters of corporate governance, including the audit as a component of corporate governance. As such, the formation of director-auditor links is argued to be contingent on the balance of power between directors and shareholders and the strength of other aspects of corporate governance beside the audit function. Empirical results support this hypothesis only for interlocking created between two or more directors of companies in the same industry. Evidence of director-auditor link association with audit quality is then sought by analysing qualifications and discretionary accruals in the presence of these links. Although alternative explanations are possible, some evidence is found of reduced audit quality. However, using the frequency with which an investor chooses to invest across companies audited by the same auditor as a measure of investor confidence in that auditor, results show that audit quality attributes are valued by investors and that director-auditor links are not associated negatively with investor confidence. Additional tests that examine the association between director-auditor links and various measures of organisational performance find little evidence of negative connotations. Public policy implications flow from the findings and these are discussed together with limitations and ideas for future research.
