외부감사인과 지배기구 간 커뮤니케이션과 감사인 노력

Previous studies have focused on the effect of the frequency of communication between auditors and governance bodies on accounting transparency. However, the quality of auditors and governance bodies was not considered in the impact of communication on auditor efforts. This study aims to analyze the effects of communication frequency, the Big 4 auditors and the audit committee on the auditor efforts, respectively, and the interaction of them. The result shows that the frequency of communication are positively associated with abnormal audit hours, indicating that the high frequency of communication and audit committee make the auditor put in a relatively greater effort. The interaction variable between the communication frequency and the Big 4 auditors are positively associated with the abnormal audit hours in only the group whose audit hours exceeded the normal level. On the other hand, the interaction variable between the communication frequency and the audit committee are positively associated with the abnormal audit hours regardless of whether the audit hours exceeded the normal level. These results indicate that the auditor quality plays a decisive role in increasing the auditor effort, and that the audit committee raises the auditor effort more than the full-time auditor. This study suggests that not only the frequency of communication between the external auditor and the governance bodies but also the quality of the auditor and the governance bodies should be considered to assess the accounting transparency of a company.
