Thesis (PhD (Business Management)—University of Stellenbosch, 2007. / Corporate Governance has engaged the attention of academics and practitioners alike for some time now. It is sad to note, however, that most of the studies carried out in this area have been conducted in countries such as the USA and the UK. In recent times, interest in Corporate Governance on the African continent has assumed heightened proportions, probably as a result of the 1997 East Asian crisis and the relatively poor performance of Corporate Africa. Melvin Ayogu who researched into governance matters around the continent pointed out that corporate governance perhaps is nothing but a mirror image of political governance bridled with a lot of corruption. In spite of the recognition that corporate governance is critical for firm performance and for sustained macroeconomic growth coupled with the heightened interest in the area, research in corporate governance has not received the needed attention on the continent. This was the main motivation for the study. In carrying out this study we considered 103 listed companies drawn from Ghana, Nigeria, Kenya and South Africa and 52 Microfinance Institutions from Ghana. Data consisted primarily of governance and financial variables. Though, most of the financial data was obtnaied through secondary sources, the governance data was essentially obtianed through questionnaire administration. Analysis of the data was done primarily within the Panel Data Framework and various shades of panel data estimations were run. This dissertation presents the results of the research work underlying seven stand-alone but related essays that focus on the relationship between corporate governance and various aspects of firm behaviour. Whilst, five of the essays dwell on corporate governance and firm attributes, one considers determinants of board size and composition by using data from Ghana and the last essay explores how corporate governance and stock market development affect economic growth. The first essay looks at corporate governance and firm performance and the second focusses on the determinants of board size and composition. The third essay concentrates on corporate governance and shareholder value maximisation. The fourth essay considers how corporate governance affects the financing choices of firms. The link between firms’ investment opportunity set and corporate governance is the subject matter of the fifth essay. While, the sixth looks at how corporate board diversity through gender affect the performance of microfinance institutions in Ghana, the last and seventh essay is devoted to an exploration of the linkage between corporate governance, stock market development and economic growth using board independence as the main governance indicator. The findings of the study indicate that large and independent boards enhance firm value and that when a CEO serves as board chair, it has negative effect on performance and such firms employ less debt. We also found that a CEO’s tenure in office enhances firms’ profitability while board activity intensity has a negative effect on firm profitability. The study also revealed that while larger boards employ more debts, the independence of a board has a significant negative relationship with short-term debt. The size of audit committees and the frequency of their meetings have a positive influence on market-based performance measures and institutional shareholding essentially sends a positive signal to potential investors thereby enhancing market valuation of firms. The study also confirmed the widely-held view that board size and its composition are functions of firm and industrial characteristics. Thus, while firm level risk has a positive relationship with board size, CEO tenure correlates negatively with board size and that firms with larger institutional shareholding employ fewer outside directors. Firms in the finance sector were seen to employ smaller board sizes and fewer outside directors partly due to the existence of other regulatory mechanisms in these institutions. More so, it was found that large board sizes enhance shareholders wealth and that both sector and country specific effects impact on shareholders value. The mining sector was seen as dominant in maximising shareholder value in terms of dividend yield. The study once again showed that shareholder value maximisation is also dependent on the level of country specific risk. Our results also point to the fact that firms with investment or growth opportunities employ large boards (high board and auditor fees), have longer CEO tenure and are profitable, and that the extent of growth response to governance structures is influenced by both country and sector specific effects. Findings again, suggest that board diversity through the inclusion of women is important for enhanced performance of microfinance institutions and the independence of corporate boards in particular is important for firm performance. These findings have important policy implications.

Corporate governance failures raise questions by stakeholders seeking explanations why audit committees are failing to play their agency role effectively. The objective of this study was to determine the relation between 49 disclosed audit committee effectiveness variables based on King III Code recommended practices and the external audit opinion expressed in South African central government departments. Descriptive statistics highlighted variances in 14 variables across 93 departments. Categorical principal component analysis categorised the 14 variables into four factor variables and hypotheses. Multivariate ordinal logistic regression tested the hypotheses. Results suggest that disclosure of a higher number of variables was generally associated with a clean audit report, while the association between a higher number of disclosures regarding audit committee structure and profile variables and a clean audit report was significant. Improvements to National Treasury’s disclosure templates and review of departmental managers’ disclosures about audit committees in annual reports are recommended. / Gevalle van korporatiewe beheer mislukking laat vrae by belanghebbers ontstaan waarom ouditkomitees versuim om hul oorsigrol doeltreffend te vervul. Die doel van hierdie studie was om te bepaal watter verband daar bestaan tussen 49 vasgestelde ouditkomiteedoeltreffendheidsveranderlikes vervat in die aanbevole praktyke volgens die King III-kode en die eksterne ouditmening wat in sentrale staatsdepartemente in Suid-Afrika uitgepreek is. Beskrywende statistiek het variasies in 14 veranderlikes oor 93 departemente uitgewys. Kategoriesebeginsel-komponentontleding het die 14 veranderlikes in vier faktorveranderlikes en hipoteses gekategoriseer. Meerveranderlike ordinale logistieke regressie het die hipoteses getoets. Resultate toon dat openbaarmaking van ʼn groter getal veranderlikes oor die algemeen verband hou met ʼn skoon ouditverslag; en die verband tussen ʼn groter getal openbaarmakings betreffende ouditkomiteestruktuur- en profielveranderlikes en ʼn skoon ouditverslag was beduidend. Verbeteringe aan Nasionale Tesourie se openbaarmakingstemplet en nasiening van departementele bestuurders se openbaarmakings rakende ouditkomitees in jaarverslae word aanbeveel. / Go palelwa ga ditshepedišo tšeo di latelwago go laola khamphani go dirile gore bengdithoto ba ipotšiše dipotšišo tše di nyakago ditlhalošo tša gore gobaneng dikomiti tša tlhakišo di šitwa go kgatha tema ya tšona ya bodiredi ka bokgoni.
