Does ESG performance mitigate earnings management? Evidence from UK takeover targets

This article presents a literature review of 49 empirical studies on key audit matter (KAM) disclosure in audit reports. The study involves a structured literature review on KAM disclosure based on the reactions of stakeholders. The limitations of former studies and useful recommendations for research are stressed. Five major streams of empirical research that analyze the impact of KAM disclosure on stakeholders’ reactions are focused: (1) shareholders (e.g. investors’ perceptions of auditors’ responsibility and litigation, value relevance and investors’ decisions); (2) debtholders (e.g. loan contracting terms); (3) external auditors (e.g. audit processes and audit fees); (4) boards of directors (e.g. earnings management); and (5) other stakeholders (e.g. informational value for suppliers and customers). The authors stress that most of the included studies use experimental or archival data and analyze the impact of KAM disclosure on investor reactions in a US-American setting. As the international standard setters assume a positive impact of KAM on stakeholder reactions, mixed empirical results are found. Although there are some indications of decreased earnings management behavior, most studies find no significant changes in auditor behavior. Furthermore, there are many insignificant results with regard to shareholders’ reaction in line with our stakeholder and behavioral agency framework. The literature review is especially useful for management decisions, because firm reputation may be positively or negatively influenced by KAM regulations.

Corporate social responsibility (CSR) reporting plays a key role in management control, particularly in light of the increased demand for non-financial reporting after the financial crisis of 2008–2009. This literature review evaluates 47 empirical studies that concentrate on the influence of several board composition variables on the quantity and quality of CSR reporting. The author briefly introduces the research framework that underpins current empirical studies in this field. This is followed by a discussion of the main variables of board composition: (1) committees (audit and CSR committees), (2) board independence, (3) board expertise, (4) CEO duality, (5) board diversity (gender and foreign diversity), (6) board activity, and (7) board size. The author, then, summarizes the key findings, discusses the limitations of the existing research and offers useful recommendations for researchers, firm practice and regulators.

This study examines the relationship between corporate social responsibility (CSR) and earnings management after controlling for endogeneity of CSR. Using a sample of non-financial firms listed on Korean Securities Market between 2002 and 2010, this study finds that ignoring endogeneity biases the estimated relation between CSR and earnings management. Specifically, the results show that the negative and significant relation between CSR commitment and discretionary accruals reported in the previous studies becomes insignificant. However, the negative and significant relation between CSR commitment and real activities manipulation remains significant even when the endogeneity of CSR commitment is taken into account. Therefore, this study provides evidence that proactive CSR engagement significantly affects firm’s practice of real activities manipulation, while it does not affect its practice of discretionary accruals. These results indicate that CSR commitment leads managers to be more responsible in management of operational activities than in accruals management.
