This research is to analyze how an introduction of full-time quality control("QC") personnel system in audit firms influences on audit quality and verify how important it is to establish the quality control system for auditing quality. We measure audit quality as the level of discretionary accruals and compare the differences between audit firms with QC and without QC. In addition, we analyze the difference in audit qualities between before and after activating the full-time QC personnel system by comparing audit quality of before 2015 with that of after 2016. The results of this study are summarized as follows. First, the audit quality is higher when audit firms have QC personnel. Second, the audit quality is improved after the introduction of the full-time QC personnel system.

The study examines the effects that non-audit service and firm's ownership structure might have on the value relevance directly or indirectly. This investigation is based on prior research which suggests that the audit firms' non-audit services is likely to adversely affect investors' perceptions of the credibility of financial reporting and that corporate governance are likely to mitigate the adverse this kind of non-audit services effects. The sample consists of non-banking firms listed on the Korea Exchange that reported annual financial statements over the period from 2004 to 2008. In the setting, stock returns as proxy for capital market response, auditor quality(measured as the discretionary accruals) is endogenously determined. This study employs a structural equation model to take into account the endogenous variables under study. The analysis influences through the path analysis that ownership structure suppress the market response through audit quality and also the non-audit service have influence on the market response through audit quality. The results of this study contribute to the literature in the following ways. First, this provides direct evidence that there is a negative association between audit firms' client importance and the value relevance. Second, the findings that the negative association is attenuated for audit quality support the findings of prior studies which present that corporate governance provide higher credibility of financial reports.

Prior literature shows that audit market concentration which is measured as the Herfindahl index is negatively associated with audit quality in Korea. This study analyzes whether characteristics of an audit committee have effect on the relation between audit market concentration and audit quality. This is because it is expected that effective audit committees restrict the tendency of dominant auditors to neglect their duties. The empirical results of this study using the sample firms having an audit committee listed in the Korea Composite Stock Price Index market for 2006-2015 are summarized as follows. First, consistent with prior research, audit quality decreases as audit market concentration increases. However, audit quality is not lowered as audit market concentration rises only when the audit committee has financial expertise among representative characteristics of an audit committee - independence, financial expertise, and activity. This research finds contributions in that it explores the effect of audit committee characteristics on audit quality in consideration of audit market concentration and utilizes the differential types of the characteristics of an audit committee at the same time.

We examined the effect of Audit Quality on Accounting Policy by using Book-Tax Difference Variability as the proxy of Accounting Information Quality. We used 2,412 sample data from 2010 to 2014. In short, the result of this study's is as followed. Audit Quality have a negative relevance with Book-Tax Difference Variability. Therefore we can support that the firm has a good Audit Quality shows the better Accounting Information Quality according to this study. This study contributes as follow. we can confirm how does Audit Quality affect Accounting Policy by this study's result. We hope that this study can be helped development of capital market and give a good news to investors on firms that has a good Audit Quality

These days, people distrust the accounting transparency of firms in Korea. It can .increase the capital costs and reduce profitability of firms. Auditors say that one of causes on the low grades of the accounting transparency is free contracts between auditors and firms. Firms want auditors take low audit fees. In principle, if auditors take low audit fees, they cannot input auditor resources to proper audit. However, there are not any empirical evidence about the relation between the audit fees dumping and the audit quality. This study defines dumping auditors if their audit fees are lower than the average of industries, and examines whether these auditors showed low audit qualities or not. As a result, firms which are audited by dumping auditors presented low abnormal accruals. We can interpret this result as that dumping auditors have low audit qualities. This result helps to make policies to improve the accounting transparency of firms.

PCAOB conducts the direct supervision for the PCAOB registered accounting firm. Therefore, if an accounting firm is registered with the PCAOB, it will thoroughly manage for their quality management systems. The registered auditor can be expected to have better quality of the audit. This study carried out the analysis using the audit fee which proxies for audit quality. The results of analysis are as follows. After controlling for foreign accounting firms affiliated status, company size, risky assets, leverage, ROA, and market-related variables, PCAOB is a significant explanatory variable for the audit fees. The results of this study support the hypothesis that PCAOB-registered auditors will provide a good audit quality.

This study's purpose is to verify how the periodically designated auditor in the recently implemented periodic auditor designation system affects audit quality. In this study, hypotheses were established by reviewing previous studies, and 980 samples of 2019 and 2020 were selected for KOSPI-listed companies. Dechow & Dichev (2002)'s accrual quality was used as the dependent variable, and the effect of whether or not a company was periodically designated as an auditor and whether or not a Big 4 auditor was selected was empirically analyzed. As a result of the analysis and correlation analysis, a statistically significant difference was confirmed in the quality of the dependent variable accrual and the independent variable designated auditor (PA). However, as a result of the regression analysis model 1, it was found that the designated auditor was not significant, but it was confirmed that there was a significant difference in the control variables. Further analysis confirmed the difference in audit quality according to the Big 4 auditors. This study is significant in that it is a study that uses empirical data to study the effect of audit quality and the selection of regularly designated auditor companies after the introduction in 2019 and 2020. Due to the non-disclosure of government-designated companies, there is a limit that there may be a difference from the selection based on the researcher's published selection criteria.

This study is an analysis of auditor's response to audit risk. Specifically, audit risk is measured by the amount of correction of the current financial statements, and auditor's response is measured by the rate of change of audit hour in next auditing. The amount of correction can be viewed as audit risk recognized by auditor because the degree of auditor's correction will increase as the company's financial statement preparation ability is lower or the profit management amount is larger. Auditor's response is measured as the rate of change of audit hour because audit risk would be incorporated in audit plan. Although auditing is performed by a team, auditor's response would differ depending on their roles. It is expected the leaders who establish the audit plan and manage the audit quality would respond more sensitively to audit risk than the other auditors. The results show that when the amount of correction is greater than a certain level, auditors recognize it as audit risk and increase total(and leaders') audit hour in next year audit.
