One of the main aims of the underlying research is to respond to continuous calls for introducing and measuring a sound economic definition for best practice disclosure quality (e.g. Beyer et al., 2010) that is derived from a reliable guidance framework (Botosan, 2004) using an innovative natural language processing technique (Berger, 2011). It also aims to examine the impact of corporate governance on best practice disclosure quality. Finally, it aims to examine the joint effect of both best practice disclosure quality and corporate governance on firm value. The thesis contributes to disclosure studies in three principal ways. First, it introduces a new measure for best practice disclosure quality. Further tests show that the proposed measure is reliable and valid. A novel feature of this measure is that it captures all qualitative dimensions of information issued by the Accounting Standards Board, 2006 (ASB) Operating and Financial Review (OFR) Reporting Statement. Second, it uses machine-readable OFR statements for financial years ending in 2006-2009, and develops a language processing technique through constructing five keyword lists. Third, it examines the extent to which disclosure quantity provides a proper proxy for disclosure quality. The analysis shows that disclosure quantity is not a good proxy for disclosure quality. Accordingly, results derived, using quantity as a proxy for quality, are questionable. Results of the association between disclosure quality and corporate governance mechanisms suggest that the most effective governance mechanisms in improving disclosure quality are leadership structure, audit committee meeting frequency, and audit firm size. Using a wide set of corporate governance mechanisms, the study also contributes to three research strands and explains the inconclusive results in relation to the association between disclosure quality, corporate governance mechanisms and firm value. It provides empirical evidence as to which governance mechanisms promote the quality of voluntarily disclosed information in large UK firms. Additionally, it provides empirical evidence as to the joint effect of best practice disclosure quality, corporate governance mechanisms on firm value in the UK. Results also show that best practice disclosure quality enjoys a substitutive relationship with two corporate governance mechanisms (audit committee independence and audit committee size) and a complementary association with board independence in relation to firm value. The study has various research and policy implications. It suggests new research avenues for re-examining disclosure relationships, especially research areas that do not have persuasive conclusions such as the economic consequences of disclosure quality. Such research may inform both regulators and managers as to the costs and benefits of disclosure quality to both firms and stakeholders. It also provides feedback on the current disclosure practices by firms so that policy-makers can modify reporting frameworks/guidance accordingly.
