    This research analyzes the impact of human resource management on audit teams and their influence on audit quality, revealing four key findings. 1. In the Japanese market, where information regarding engagement partners is highly transparent, partners experience negative consequences commensurate with their responsibility for audit failures. 2. Despite the mandatory rotation requirement, partner rotations are structured to prevent multiple partners from rotating at the same time. However, voluntary rotations are often associated with fluctuations in audit fees. 3. The composition of the partner team, the availability of internal resources, and the combination of team members significantly influence audit quality. 4. The adoption of technology in audit engagements is influenced not just by engagement team members but also by societal factors, client characteristics, and progress in institutional frameworks.

    The study initially focused on analyzing fraudulent financial reporting and the audit judgments during the occurrence of fraud and after discovery. However, as the study progressed, the focus was expanded to include a comprehensive examination of misstatements. As a result, the study examined the prevalence of misstatements in financial reports published by Japanese listed firms, as well as the consequences of their discovery for auditors and investors. it documented misstatement disclosure in Japan, the magnitude of misreported accounting earnings, and the negative stock price reaction that followed their discovery. Furthermore, it revealed that audit engagement partners accountable for misstatements face negative consequences, such as unexpected partner turnover and a decrease in their clients. Lastly, while the discovery of misstatements worsens the information environment for investors, restatements mitigate this deterioration.

    This study empirically analyzes the consequences that occur when financial misconduct is revealed and the determinants of their effects, targeting Japanese listed companies and auditors. The main results are as follows. (1) The stock price of a misconduct firm is less likely to keep declining in the cases that a third-party (independent) committee investigates it. (2) Firms with restatement due to financial misconduct are more likely to clean up their prior discretional accounting process and improve the quality of their financial reporting in subsequent periods. (3) Audit partners who signed the restated period are more likely to be replaced by their current clients, not only by clients who were revealed misstatements.
