PurposeThe purpose of this study is to examine the interrelationship between modified audit opinions and earnings management as measured by discretionary accruals and develop a thorough understanding regarding the moderating effect of audit quality on this relation.Design/methodology/approachThis study uses a sample of Tunisian listed firms on the Tunis Stock Exchange during 2006–2013. Four models are developed and tested by using panel logistic and Feasible Generalized Least Squares (FGLS) regressions.FindingsThe results show that earnings management increases the likelihood of receiving a modified audit opinions. Then firms receiving modified audit opinions manage earnings more than those receiving clean opinions. It is also discovered that audit quality moderates the relationship between audit opinion and earnings management.Practical implicationsThis paper contributes to the literature of both audit and management studies and represents the first effort to examine the relation between audit opinion and earnings management, with audit quality as a moderating variable.Originality/valueThis study extends existing research on earnings management and audit opinion. Thus, this study has the potential to help stakeholders, board of directors, regulators and auditors, who are related with enhancing the supervision of firms and reducing the opportunities given to managers, to engage in earnings management. It constitutes an addition to previous knowledge about audit opinion in the Tunisian context before and after revolution.

Purpose The purpose of this study is to document the mediating effect of earnings management on the relation between the components of audit certification. The study is performed under different levels of corporate governance effectiveness in the Tunisian context. The main objective is to empirically examine the ability of discretionary accruals to mediate the relationship between the audit reporting quality and audit risk and to define how the levels of risk governance moderate this relation. Design/methodology/approach Structural equation modeling (SEM) approach is applied for a panel data set of 28 Tunisian companies listed in the Tunis Stock Exchange (TSE) between 2006 and 2013. Furthermore, a moderated-mediation model is developed to examine the mediating role of earnings management. This model is considered to emphasize the moderating role of corporate governance on the relationship between audit-reporting quality and audit risk. Findings The results of this study show that earnings management mediates the moderating role of corporate governance on the relationship between timely disclosure and audit risk. Thus, this investigation empirically demonstrates that risk governance moderates both the relationship between the timely disclosure and earnings management, and the relationship between earnings management and audit risk, i.e., the mediating role of earnings management varies depending on the level of risk governance. Practical implications Investors and other external users of financial statements need to care about the audit risk by the audit-reporting quality (audit accuracy and timely disclosure). Moreover, all factors that may influence the audit risk should be identified. This identification can help guide the reforms to improve the functioning of the financial market. Originality/value This study can enhance knowledge and understanding on how motivational and environment factors influence the audit risk. Using data from the Tunisian market, this work fills a research gap by examining the audit risk and identifies a new governance risk index. The specificity of the country where the study is elaborated refers to its accurate “revolutionary” transitional phase. Tunisia aims to enhance economic growth and to establish general strategic governance of the country, particularly strategic governance of companies.

PurposeThe purpose of this paper is to investigate the potential influence of internal and external corporate governance mechanisms on audit risk in Tunisian companies.Design/methodology/approachBased on a sample of Tunisian non-financial firms listed on the Tunisian Stock Exchange (TSE) over the periods 2005 to 2010 (pre- 2011 revolution) and 2011 to 2017 (post −2011 revolution), consisting of 371 observations for the whole period, the authors apply the generalized least square (GLS) to test the research hypotheses and model.FindingsThe results are consistent with the agency theory suggesting that efficient corporate governance is able to control and reduce a company’s agency problem. Evidence reveals that the effectiveness of the director’s board/ownership structure and audit quality have the most influence on audit risk before than after the 2011 revolution, although governance mechanisms should play a more active role in encouraging companies to be more transparent in the post-revolution period. Moreover these findings are confirmed when identifying a composite measure of corporate governance.Practical implicationsSignificant implications are provided for analysts, investors, regulators and academics. First, findings can help Tunisian regulators determine corporate governance disclosure requirements. Second, this research will make investors and stakeholders aware of the fact that minimizing auditor risk will be effective in reducing agency problems in emerging markets like Tunisia. Then, this work can help researchers better understand and realize the corporate governance role in the quality of audit process and financial statements and encourage them to deeply and broadly investigate this issue on other emerging markets.Originality/valueThis study stands for an extension of the existing research on corporate governance and audit risk. It fills a research gap in the local context. In fact, the considered data are those of the pre- and post-revolution Tunisian market, mainly in periods of instability. Although emerging markets make up the vast majority of economic activity around the world, they have received limited attention in academic research.

Research question: This study investigates and analyzes the influence of earnings management on audit report lag. It also intends to develop a thorough understanding regarding the mediating effect of audit risk on this relation. Motivation: The outcomes of this paper will help to bridge the knowledge gap related to this issue in developing countries due to the importance of audit delay as it relates to corporate transparency. Idea: The issue of reporting delay is important as it relates to corporate transparency. Data: This study is based on a sample consisting of 28 Tunisian companies listed in the Tunis Stock Exchange (TSE) over the periods 2005 to 2010 (pre-2011 revolution) and 2011 to 2017 (post-2011 revolution). Tools: Consisting of 364 observations for the whole period, Structural Equation Modeling (SEM) approach is applied and three models are developed to examine the direct and the indirect link between earnings management and audit report lag. Findings: The results show that firms which manage their earnings upward are more likely to accelerate the release of their financial statements. In addition, in the Tunisian context, audit risk mediates the relationship between earnings management and audit report lag. Contribution: This study extends the existing literature by examining the mediation effect of audit risk on the relationship between earnings management and audit report lag.
