The relationship between corporate social responsibility and earnings management: accounting for endogeneity

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 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.

This study examines the effect of foreign directors in the board of directors on the monitoring function by analyzing the association between foreign directors and opportunistic financial reporting. The authors address this question by examining the effect of the foreign directors in the board on firms’ discretionary accruals and book-tax difference. The researchers analyze by using Korean firm data for the years 2001–2014 as Korea is one of the few countries that nepotism is strong within the board, providing the ideal setting to analyze the effect of foreign directors on the monitoring function of the board. The authors find that foreign directors have a positive effect on the monitoring function of the board, as discretionary accruals and book-tax differences of firms with foreign directors are lower than those without foreign directors. Further, the researchers find that the positive effect of foreign directors on the monitoring function is more pronounced if foreign directors are independent directors or expertise in accounting or finance. Overall, the findings support the view that foreign directors in the board increase the board diversity, which increases the independence of the board and so the monitoring function.
