The purpose of this study is to make an empirical analysis of how voluntary disclosure level has an impact on auditor's audit fees and audit hours and additionally identify if the relationship between the twos depends on the accounting quality. As final sample for analysis, this study targeted the KOSPI listed firms from 2007 to 2013, and as for audit fees(audit hours), 4,572 (4,460) corporate/annual data were used. The results from the empirical analysis in this study are as follows. First, auditor's audit fees appeared higher in KOSPI listed firms compared to the non-KOSPI listed firms, and when targeting the KOSPI listed firms only, the results were the same. Second, auditor's audit hours increased significantly in the KOSPI listed firms compared to the non-KOSPI listed firms, and this result appeared consistently even when analyzing the KOSPI listed firms only. Third, when the accounting quality was not good in the KOSPI listed firms, auditor's audit fees got significantly lower, whereas when targeting the KOSPI listed firms only, no relevance was found. Fourth, when the accounting quality was bad in the KOSPI listed firms, auditor's audit hours were found to have been spent less, but when analyzing the KOSPI listed firms only, such a fact was not identified. This study is significant in that it examined the fact that auditor's audit risk depends on voluntary disclosure level in terms of audit fees and audit hours.

This study investigates the direct and indirect effects, mediated by audit committee quality, of managerial ownership, institutional ownership, and profitability on intellectual capital (IC) disclosure. The object observed of this study is companies listed on the Indonesia Stock Exchange (IDX) in the 2014-2018 period that are classified as high intellectual capital-intensive industries. Based on the sampling method, purposive sampling, 51 companies were selected as samples. This study used path analysis techniques with IBM SPSS version 25 to study the direct and indirect influences of managerial ownership, institutional ownership, and profitability toward IC disclosure. The results of this study show that managerial ownership, profitability and audit committee quality have a significant positive effect on IC disclosure whereas institutional ownership has significant negative effect on IC disclosure. This study also provides empirical evidence, supported by the sobel test, that the audit committee quality is able to mediate the effect of institutional ownership and profitability on IC disclosure. However, the audit committee quality is not able to mediate the effect of managerial ownership on IC disclosure. These findings develop and strengthen the results of prior studies related to the implementation of signaling theory and agency theory in devoting more understanding about IC disclosure.

This paper aims to explore the relationship between the quality of the audit and the level of stock return co-movement in the context of the Vietnamese emerging market. The empirical study is designed based on the quatitative method and deductive approach. The panel dataset includes 256 listed firms from different industries,with 1115 firm-year observations on Ho Chi Minh City Stock Exchange for the period from 2014 to 2018. In the research, we built the econometric regression model, using stock return synchronicity and audit quality as the dependent and independent variable, respectively. Some control variables are also added to the econometric regression models as they are well-documented in prior research to have an effect on stock price synchronicity. To improve the accuracy of the regression coefficients, beside the Ordinary Least Squares, we employ the Random Effects Model and the Fixed Effects Model for better statistical analysis of panel data set. The results show that the quality of the audit is positively correlated to stock price synchronicity. This finding suggests that stock returns of companies with higher quality of the audit are more synchronous with the market. Results for other control variables also support our reasoning for the main findings.

The focus of this study is to investigate the effect of earnings management and audit quality on the cost of equity capital and also examines whether audit quality acts as a moderating variable for the effect of earnings management on the cost of equity capital. The population in this study are companies from the consumer goods industry sector listed on the Indonesia Stock Exchange (IDX) during the 2016-2018 period. This sector was chosen because it is a sector that is able to survive in conditions of economic decline, so it becomes a good investment opportunity in the future. The sample selection was carried out using purposive sampling technique. By using the Moderated Regression Analysis (MRA) technique, the results show that earnings management has a positive effect on the cost of equity capital. Conversely, companies with good audit quality will bear lower cost of equity capital. The moderating hypothesis test results show that audit quality moderates the effect of earnings management on the cost of equity capital. This means that, even though the company carries out earnings management, investors have more confidence in the results of audits conducted by qualified auditors so that the cost of equity capital is low.

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.

One of the methods of securing the reliability of accounting information is maintaining high audit quality. The first step of improving audit quality is lowering audit engagement risks. Thus, this study analyzed the relationship between the characteristics of accounting firms and audit engagement risks based on the Bayesian Network. For this, Markov Blanket, the minimum explanatory variable set, which affects audit engagement risks, was presented, and based on the drawn causal relationship, sensitivity analysis was conducted to verify the characteristics of accounting firms, which affect audit engagement risks. The existing preceding research that used multiple regression analysis presumes the linearity between explanatory variables and dependent variables, so there was a limit in drawing the relationship between explanatory variables. Therefore, this study figured out the interdependence between variables using the General Bayesian Network and examined the impact that each variable has finally on audit engagement risks that affects the audit quality. The results of this study would greatly contribute to improving the efficiency of the supervisory task by allowing a supervisory institution to identify an accounting firms that does not manage audit engagement risks properly and to improve the supervision of the accounting firms in advance. In addition, this study will be used as a reference when a supervisory institution would improve the system related to audit quality by presenting the characteristics of accounting firms related to the audit quality.

Purpose: This article aims 1) to propose improvement directions of the certification by recognizing the quality management practices based on the analysis of the audit results of the military contractors and 2) to suggest some ideas on quality audit planning preparation to help the government quality assurance representatives. Methods: Based on the nonconformity report of the defense quality management system (DQMS) requirements, frequently occurring requirement components are found and summarized. Three hypothesis testings are executed to check whether the maturity levels of the quality management systems are influenced by the company size, weapon tye, and company type, regarding the nonconformity frequency as dependent variable. Results: Nonconformity occurs most frequently in the order of product realization, measurement analysis and improvement, management responsibility, resource management, and quality management system. Nonconformity reduces when the company size increases, for the guided weapons, and in the defense companies. Conclusion: Since small-sized companies are inferior to larger companies with respect to the DQMS maturity level, more support should be provided to these small-sized companies which produce military supplies.
