We investigate whether auditors input additional audit hours according to the sizes of book-tax differences (hereinafter BTD) and request additional audit fees for additional audit hours. In addition, the interaction effects of corporate governance on the relationships between BTD and audit hours/audit fees are examined using the total corporate governance (TCG) scores, data from the Korea Corporate Governance Service (KCGS). We predict that since auditors have the incentive and ability to consider BTD, audit hours and audit fees will increase when BTD are larger. Empirical results of our study are as follows. First, BTD and audit hours (LnAH) show a negative (-) association that is not statistically significant. Second, audit fees (LnAF) were shown to increase along with BTD. This can be interpreted as a result of requests for additional audit fees for increased audit risks due to individual firms' BTD. Third, the interaction effect of corporate governance on the relationship between BTD and audit hours (LnAH) showed a positive (+) association, but the association was not statistically significant. Fourth, the interaction effect of corporate governance on the relationship between BTD and audit fees (LnAF) showed a statistically significant positive (+) association. This be understood as meaning that firms with better governance make more efforts for financial reporting in order to maintain their reliability in the market. This study contributes to the literature in several important aspects. First, it empirically demonstrates whether auditors properly reflect BTD on audit risks. Next, our study is analyzes the effects of corporate governance on the relationship between BTD and audit hours/audit fees using the total corporate governance (TCG) scores presented by the Korea Corporate Governance Service (KCGS). Finally, our findings empirically showed social proof function of accounting audits as a strategy to reduce information risks.
This study empirically examines the relationship between corporate sustainable management (CSM) and dividend policy. Among the various motivations related to dividends, this study examines the relationship between CSM and dividend policy based on the agency and signaling theory. After examining the relationship between CSM and dividend policy, we investigate whether belonging to a large business group (chaebol group) has a significant effect on the relationship between CSM and dividend policy. The analysis period is from 2011 to 2018, and the ESG ratings of the Korea Corporate Governance Service are used as proxies for CSM. The empirical results show that CSM and dividends have a significant relationship in the positive direction. This means that firms with excellent CSM activities have higher dividend levels than those that do not. Furthermore, the association between CSM and dividends is more negative for firms belonging to a chaebol group. This indicates that the positive relationship between CSM and dividends in a firm that belongs to a chaebol group is weakened. This means that the relationship between CSM and dividends in the group belonging to the chaebol group is weakened. It belongs to the group of conglomerates, meaning that the relationship between the amount of dividends and CSM weakened. Our study focuses on CSM as a determinant of dividends, and examines the effects of belonging to a chaebol group in the relationship between CSM and dividends. Given that resolving the interest incompatibility between investors and managers is the focus of corporate governance, dividend policies can be used as a method for resolving the interest incompatibility between investors and managers.
This study examined the effect of corporate governance on labor investment efficiency, using 5178 firm-year samples from companies listed on the Korean stock market over the period from 2011 to 2019. In addition, the relationship between corporate governance and labor investment efficiency according to whether the company belongs to a chaebol group was examined. Corporate governance was measured using KCGS’s corporate governance ratings. This study tried to verify whether labor investment inefficiency due to information asymmetry is improved by excellent corporate governance. The results show that in the case of the entire sample, the relationship between corporate governance and labor investment efficiency was significant in the positive (+) direction. That is, it is an empirical result indicating that a company with a sound governance structure is making effective labor investment. The samples were divided into overinvestment samples and underinvestment samples, and the relationship between corporate governance and labor investment efficiency was analyzed separately in the two samples. According to the results, the positive relationship between corporate governance and labor investment efficiency was significant only in the case of underinvestment samples. In addition, the positive relationship between corporate governance and labor investment efficiency was more statistically significant in the case of companies belonging to a chaebol group. This study provided implications for authorities, shareholders, and investors, etc., in that it suggests the role of corporate governance as a mechanism to alleviate the agency problem between managers and investors.
This study empirically analyzes the relationship between corporate sustainable management (CSM) and audit report lag. From the perspective of the agency theory that information asymmetry is resolved through CSM, audit report lag was predicted to decrease and was subsequently analyzed. The analysis results are as follows. First, the relationship between CSM and audit report lag was significant in the negative trend. This means that companies that actively engage in CSM have a shorter audit report lag than those that do not. Second, the relationship between CSM and audit report lag according to auditor size showed a significant negative trend only in the group with a large auditor size. Third, the relationship between CSM and audit report lag according to the quality of earnings showed a significant negative trend only in the group with good earnings. In other words, the relationship between CSM and audit report lag varies depending on the size of the auditor and the quality of earnings. This study is meaningful in that it directly examines the impact of CSM on audit report lag, focusing on the period following the introduction of K-IFRS. The results of this study have important implications for not only managers, but also investors and supervisory institutions, in that CSM not only increases corporate value through improved earnings quality, but also affects the performance of the auditor.
Using data on the firms' voluntary disclosures from the Korea Stock Exchange from 2011 to 2014, we first empirically examine the association between voluntary disclosure and information asymmetry and then investigate the extent to which this association is affected by accruals quality since Korea adopted International Financial Reporting Standards (IFRS) in 2011. We use Comprix et al. (2011) and Shin and Park (2014)'s measures of information asymmetry. They are daily stock return volatility (VOLA) and trading volume turnover (VOL). We use the Dechow et al.'s (1995) revised Jones model and the Kothari et al.'s (2005) performance matched discretionary accrual model to measure the discretionary accruals. The absolute values of discretionay accruals are used as proxies for accruals quality. Final research samples with voluntary disclosure for this study are 1,226 (firms-years) companies. The research findings generally support our hypotheses. First, the relation between voluntary disclosure and information asymmetry is statistically and significantly positive as we have expected. The Korean companies with high voluntary disclosure would experience higher daily stock return volatility and less trading volume, which implies that companies tend to disclose biased information to the outside, which is consistent with prior studies in Korea. Second, the accruals quality (moderating variable) on the relation between voluntary disclosure and information asymmetry is statistically and significantly negative. Thus, we can conclude that when accruals quality is high, more voluntary disclosure decreases information asymmetry. These findings imply that accruals quality works as a mechanism in reducing the negative effect of voluntary disclosure on information asymmetry after the adoption of IFRS in Korea. The limitation of this study is such that we might not have considered other omitted variables and other proxies for the accruals quality, voluntary disclosure, and information asymmetry.
