Why African stock markets should formally harmonise and integrate their operations

Despite experiencing rapid growth in their number and size, existing evidence suggests that African stock markets remain highly fragmented, small, illiquid and technologically weak, severely affecting their informational efficiency. Therefore, this study attempts to empirically ascertain whether African stock markets can improve their informational efficiency by formally harmonising and integrating their operations. Employing parametric and non-parametric variance-ratios tests on 8 African continent-wide and 8 individual national daily share price indices from 1995 to 2011, we find that irrespective of the test employed, the returns of all the 8 African continent-wide indices investigated appear to have better normal distribution properties compared with the 8 individual national share price indices examined. We also report evidence of statistically significant weak form informational efficiency of the African continent-wide share price indices over the individual national share price indices irrespective of the test statistic used. Our results imply that formal harmonisation and integration of African stock markets may improve their informational efficiency

Governance Structures, Voluntary Disclosures and Public Accountability: The Case of UK Higher Education Institutions

Purpose: We investigate the extent of voluntary disclosures in UK higher education institutions’ (HEIs) annual reports and examine whether internal governance structures influence disclosure in the period following major reform and funding constraints. Design/methodology/approach: We adopt a modified version of Coy and Dixon’s (2004) public accountability index, referred to in this paper as a public accountability and transparency index (PATI), to measure the extent of voluntary disclosures in 130 UK HEIs’ annual reports. Informed by a multi-theoretical framework drawn from public accountability, legitimacy, resource dependence and stakeholder perspectives, we propose that the characteristics of governing and executive structures in UK universities influence the extent of their voluntary disclosures. Findings: We find a large degree of variability in the level of voluntary disclosures by universities and an overall relatively low level of PATI (44%), particularly with regards to the disclosure of teaching/research outcomes. We also find that audit committee quality, governing board diversity, governor independence, and the presence of a governance committee are associated with the level of disclosure. Finally, we find that the interaction between executive team characteristics and governance variables enhances the level of voluntary disclosures, thereby providing support for the continued relevance of a ‘shared’ leadership in the HEIs’ sector towards enhancing accountability and transparency in HEIs. Research limitations/implications: In spite of significant funding cuts, regulatory reforms and competitive challenges, the level of voluntary disclosure by UK HEIs remains low. Whilst the role of selected governance mechanisms and ‘shared leadership’ in improving disclosure, is asserted, the varying level and selective basis of the disclosures across the surveyed HEIs suggest that the public accountability motive is weaker relative to the other motives underpinned by stakeholder, legitimacy and resource dependence perspectives. Originality/value: This is the first study which explores the association between HEI governance structures, managerial characteristics and the level of disclosure in UK HEIs

Antecedents of Voluntary Corporate Governance Disclosure: A Post-2007/08 Financial Crisis Evidence from the Influential UK Combined Code

Purpose: This study investigates the level of compliance with, and disclosure of, good corporate governance (CG) practices among UK publicly listed firms, and consequently ascertains whether board characteristics and ownership structure variables can explain observable differences in the extent of voluntary CG compliance and disclosure practices. Design/Methodology/Approach: The study uses one of the largest datasets to-date on compliance and disclosure of CG practices from 2008 to 2013 containing 120 CG provisions drawn from the 2010 UK Combined Code relating to 100 UK listed firms to conduct multiple regression analyses of the determinants of voluntary CG disclosures. A number of additional estimations, including two stage least squares, fixed-effects and lagged structures, are conducted in order to test the robustness of the findings. Findings: The results suggest that there is a substantial variation in the levels of compliance with, and disclosure of, good CG practices among the sampled UK firms. We also find that firms with larger board size, more independent outside directors and greater director diversity tend to disclose more CG information voluntarily, whereas the level of voluntary CG compliance and disclosure is insignificantly related to the existence of a separate CG committee and institutional ownership. Additionally, the results indicate that block ownership and managerial ownership impact negatively on voluntary CG compliance and disclosure practices. The findings are fairly robust across a number of econometric models that sufficiently address various endogeneity problems and alternative CG indices. Overall, the findings are generally consistent with the predictions of neo-institutional theory. Originality/Value: This paper extends, as well as contributes to the extant CG literature by offering new evidence on compliance with, and disclosure of, good CG recommendations contained in the 2010 UK Combined Code following the 2007/08 global financial crisis. This paper also advances the existing literature by offering new insights from a neo-institutional theoretical perspective of the impact of board and ownership mechanisms on voluntary CG compliance and disclosure practices.

Corporate governance, Islamic governance and earnings management in Oman: A new empirical insights from a behavioural theoretical framework

Purpose: This paper examines the impact of corporate (CG) and Islamic (IG) governance mechanisms on corporate earnings management (EM) behaviour in Oman. Design/Methodology/Approach: We employ one of the largest and extensive datasets to-date on CG, IG and EM in any developing country, consisting of a sample of 116 unique Omani listed corporations from 2001 to 2011 (i.e.,1,152 firm-year observations) and a broad CG index containing 72 CG provisions. We also employ a number of robust econometric models that sufficiently account for alternative CG/EM proxies and potential endogeneities. Findings: First, we find that, on average, better-governed corporations tend to engage significantly less in EM than their poorly-governed counterparts. Second, our evidence suggests that corporations that depict greater commitment towards incorporating Islamic religious beliefs and values into their operations through the establishment of an IG committee tend to engage significantly less in EM than their counterparts without such a committee. Finally and by contrast, we do not find any evidence that board size, audit firm size, the presence of a CG committee and board gender diversity have any significant relationship with the extent of EM. Originality: To the best of our knowledge, this is a first empirical attempt at examining the extent to which CG and IG structures may drive EM practices that explicitly seeks to draw new insights from a behavioural theoretical framework (i.e., behavioural theory of corporate boards and governance). Keywords: Corporate governance, Islamic governance, earnings management, behavioural theory, endogeneity, Oman. Paper type: Research pape

Can emerging African Stock Markets improve their informational efficiency by formally harmonising and integrating their operations?

Despite experiencing rapid growth in their number and size, African stock markets remain highly segmented, small, illiquid and technologically bankrupt, severely affecting their informational efficiency. On this basis, with specific focus on the weak-form of the efficient markets hypothesis, we attempt to empirically ascertain whether African stock markets can improve their informational efficiency by formally harmonising and integrating their operations using a new robust non-parametric variance-ratios test in addition to its parametric alternative. On average, we find that irrespective of the diagnostic used, all the 24 African continent-wide indices applied returns’ display better normal distribution properties than those of the 8 individual national stock price indices examined. We record evidence of statistically significant improvements in the informational efficiency of the African continent-wide stock price indices over the individual national stock price indices used irrespective of the test statistic applied. The potential improvement in efficiency to be gained is much higher in economic sectors indices than in size and regional indices. Finally, consistent with prior evidence, (eg., Wright, 2000; Belaire-Franch and Opong, 2005, Ntim, et al., 2007), the results of the Lo and MacKinlay (1988) parametric variance-ratios test are ambiguous. By contrast, the ranks and signs alternative offer consistent results throughout.African stock markets, Integration, Efficiency, Variance-ratios, Ranks and signs

Corporate Boards and Ownership Structure as Antecedents of Corporate Governance Disclosure in Saudi Arabian Publicly Listed Corporations

We investigate whether and to what extent publicly listed corporations voluntarily comply with and disclose recommended good corporate governance (CG) practices, and distinctively examine whether the observed cross-sectional differences in such CG disclosures can be explained by ownership and board mechanisms with specific focus on Saudi Arabia. Our results suggest that corporations with larger boards, a big-four auditor, higher government ownership, a CG committee and higher institutional ownership disclose considerably more than those that are not. By contrast, we find that an increase in block ownership significantly reduces CG disclosure. Our results are generally robust to a number of econometric models that control for different types of disclosure indices, firm-specific characteristics and firm-level fixed-effects. Our results have important implications for policy-makers, practitioners and regulatory authorities, especially those in developing countries across the globe

Human resource disclosures in UK corporate annual reports: To what extent do these reflect organisational priorities towards labour?

Our study analyses the nature, quality and extent of human resource disclosures (HRDs) of UK Financial Times Stock Exchange (FTSE) 100 firms by relying on a novel disclosure index measuring the depth and breadth of disclosures. Contextually, we focus on the five-year period following the then Labour government’s attempts to encourage firms to formally report on their human resource management practices and to foster deeper employer-employee engagement. First, we evaluate the degree to which companies report comprehensively (or substantively) on a number of HRD items that we classify as “procedural” or “sustainable.” Second, we hypothesise that a company’s employee relation ideology (using a proxy to measure a company’s level of “unitarism”) is positively associated with HRD. Our results indicate that: (i) whilst there has been an increase in the breadth of HRD in terms of procedural and sustainable items being disclosed, the evolution towards a more comprehensive and in-depth form of HRD remains rather limited; and (ii) there is a positive association between a company’s employee relation ideology (unitarism) and the level of HRD. Theoretically, we conceive of HRD both as a reflection of an organisation’s orientation towards a key stakeholder (unitarist relations with labour) and a legitimacy seeking exercise at a time of changing societal conditions. We contribute to the scant literature on the extent and determinants of HRD since prior research tends to subsume employee-related disclosures within the broader concept of social, ethical or intellectual capital disclosures. We also propose a disclosure checklist to underpin future HRD research

Effectiveness of board governance and dividend policy as alignment mechanisms to firm performance and CEO compensation

Purpose: The purpose of the study is to investigate whether operating and market performance are aligned to CEO compensation and how board governance and dividend policy could influence pay–performance link in the capital market of Pakistan. Design/methodology/approach: The hand-collected information on 219 non-financial firms listed on the Pakistan stock exchange (PSX) is acquired over the period 2012–2016. Additionally, panel data technique, namely Prais–Winsten (PCSE) and 2SLS (robust standard errors) regression are applied to account for the heteroscedasticity, serial correlation and endogeneity issue. Findings: The empirical results indicate that CEO compensation is positively associated with operating performance and market performance. The evidence also provides partial support to agency perspective that board independence and optimal board size could positively, while CEO duality negative moderates the relationship between operating performance and CEO compensation. However, none of these mechanisms are proved to be effective in aligning market performance to CEO compensation. In fact, dividend policy negatively moderates the association between firm performance (operating and market) and CEO compensation. Thus, contrary to the agency theory’s proposition, dividend policy cannot be utilized as a substitute control device in the absence of strong corporate governance mechanisms. Practical Implications: In light of this empirical evidence, regulatory bodies in Pakistan could improve corporate governance mechanisms as well as CEO compensation structure to ensure remunerative and ethical financial market. Originality/value: This study contributes to the academic literature by validating the underexplored pay–performance alignment propositions of agency theorists, especially in the reference of Pakistan

Governance structures and the compensation of powerful corporate leaders in financial firms during M&As

We examine the impact of mergers and acquisitions (M&As) on the compensation of powerful corporate leaders [i.e., boards of directors, including Chief Executives Officers (CEOs), Chief Financial Officers (CFOs), and Board Chairs] of acquiring firms. Using one of the largest datasets on M&As, directors’ compensation, and governance to-date, consisting of a sample of UK financials (banks, insurance firms, private equity firms, and speciality finance firms) over a 13-year period, our results obtained by employing multivariate regression analyses show that acquisitions, on average, have a positive and significant impact on directors’ compensation. This effect applies to both powerful corporate executives (CEOs, CFOs, and all other executive directors) and other non-executive directors. However, the positive acquisition effect on top executive compensation is much higher in larger and more complex acquisitions. We also find that much of the acquisition-related pay raises is equity-based rather than cash-based. Finally, we find CEOs to be the top beneficiaries from acquisitions. We interpret our findings within a multi-theoretical framework that draws insights from agency, executive power, managerial talent, and tournament theories of top executive compensation
