The primary objective of the agency research in the game theory lives in the maintenance of Pareto is optimal condition for the optimal incentive contract. The basic concepts which are related to this objective are reviewed in connection with the general assumptions to model it, the moral hazard and adverse selection which arised from the information asymmetry, and finally the problem of risk distribution. The demand for auditing and the role of auditor have been addressed by ASOBAC. Issues which an auditor is explicitly introduced in a principal-agent framework have been addressed in this paper. These issues must be confronted to appropriately with the auditor, and to achieve an adequate understanding of optimal confronting arrangement with the auditor. The first step in introducing an auditor into this analysis is to examine the game-theoretic foundation of such a expended agency model. The Mathematical program formulated may not yield solution that are resonable. This arises because the program may call for the auditor and manager to play dominated Nash equilibra in some subgame. The nontrivial natures of the subgame implies that randomized strategies by the auditor and manager nay be of crucial importance. The possibilities for overcoming the randomized strategy problem were suggested; change the rule of the game and or impose covexity condition. The former seems unjustifiable in on auditing context, and the latter promising but difficult to achieve. The discussion ended with an extension of the revelation principle to the owner manager-auditor game, assuming strategies. An examination of the restriction and improvement direction of the basic concept of agency theory was addressed in the later part of this paper. Many important aspects of auditor incentives are inherently multiple-agent, multiple-period, multiple-objectine, phenomena and require further analyses and researches.

Purpose - The purpose of this study is to empirically investigate whether the auditor accreditation system for IPO firms improves the efficiency of the KOSDAQ IPO market. To verify the effectiveness of the auditor designation system, we time series compare four measures of IPO firms (earnings management, long-term stock performance, change in operating performance, and possibility of delisting). Design/methodology/approach - We test the hypothesis through event research method and regression analysis. Specifically, the dependent variables of the regression model are discretionary accruals in the year of IPO, 36-month holding period excess return after IPO, change in operating performance for 3 years after IPO, and dummy variable for delisting. And the explanatory variable is a dummy variable that separates the period before and after the implementation of the auditor designation system. Findings - We find that earnings management and delisting risks decreased more in the period after the implementation of the auditor accreditation system than in the previous period. In addition, we find that long-term stock performance and operating performance after IPO increase further after the implementation of the auditor accreditation system. Research implications or Originality - Overall, the results of this study suggest that the implementation of the auditor accreditation system for IPO firms contributes to improving market efficiency in the KOSDAQ market, where information asymmetry is high. Our study differs from previous studies in that it demonstrates the effectiveness of the auditor designation system using various measures.

Purpose - This study investigates the effect of auditor change on client firm's accounting (financial statement) comparability. Design/methodology/approach - The comparability of accounting information is measured by the difference in accruals between the two firms. Additionally, the study uses earnings-stock return relationship as another proxy of accounting comparability. In particular, the paper examines whether there is a systematic difference between initial audit years and the other years with respect to the client firm's accounting comparability. Moreover, current study tests how changes in auditor size or industry expertise before and after the switch of auditors affect the accounting comparability. Findings - The results show that the level of accounting comparability is lower in the year of auditor change than in the other years. Furthermore, this lower level of comparability is derived by the observations that switch their auditors from non-Big4 to non-Big4 or from non-specialist to non-specialist. These results are consistent when accounting comparability is measured by different proxies. Research implications or Originality - The findings of this study provide important policy implications for the regulations related with auditor selection.

감사기구는 조직 내에서 감시와 통제 활동을 통해 전문경영인의 기회주의적인 의사결정과 행위를 줄여 주는 기능을 수행하는 내부통제 메커니즘으로서의 높은 독립성이 요구된다. 본 연구는 기업의 소유구조 상의 특성들이 상근감사의 독립성에 미치는 영향을 분석하는데 주된 목적을 두고 실행되었다. 그리고 이 같은 목적을 달성하기 위하여 상근감사의 독립성을 전문경영인과의 학연과 출신기업을 기준으로 산출한 후 전문경영인의 지분율이 독립적인 상근감사의 선임에 미치는 영향을 분석하였으며, 내부대주주인 특수관계인과 외부대주주인 기관투자자 및 외국인투자자의 지분율이 이 같은 관계에 미치는 조절효과를 분석하였다. 분석결과에 따르면 전문경영인의 지분율과 상근감사의 독립성은 부(-)의 관계가 있으며, 특수관계인의 지분율은 이 같은 관계를 정(＋)의 방향으로 조절하는 것으로 나타났으나, 외국인투자자와 기관투자자 지분율의 조절효과는 통계적으로 유의하지 않았다. 이러한 연구 결과는 전문경영인은 자신의 지분율이 높아 질수록 강화된 권한을 활용하여 독립성이 낮은 상근감사를 선임하려고 시도하는 반면, 특수관계인들은 자신들의 부를 보호하는데 도움이 되는 독립성이 높은 상근감사를 선임하고자 한다는 사실을 보여주고 있다. 본 연구는 기업의 소유구조 상의 특성들이 독립적인 상근감사의 선임에 미치는 영향을 분석한 첫 번째 연구로서, 분석결과는 전문경영인과 소유구조 상의 특성에 따른 상근감사 선임기준에 대한 실무적 가이드라인을 제공하고 있다.

선행연구를 통해 자유선임제도의 폐해를 방지하기 위한 여러 제도의 도입이 회계정보의 투명성을 개선시켰다는 점이 밝혀졌다. 그러나 이들 선행연구들은 제도 도입 전후만을 살펴보았다는 한계점을 갖는다. 따라서 제도의 도입이 장기적으로도 효과가 있었는지 여부를 살펴보는 것은 중요한 의미를 갖는다고 할 수 있다. 이에 본 연구는 1995년부터 2004년까지 한국증권선물거래소(KRX)에 상장되어 있는 12월 결산법인을 대상으로 외부감사인 교체빈도가 회계이익의 질에 미치는 영향을 실증분석하였다. 회계이익의 질은 모형과 수정 Jones모형(1991)을 통해 측정하였다. 실증 분석결과, 외부감사인 교체빈도가 높은 기업의 재무보고 신뢰성(회계이익의 질)이 그렇지 않은 기업의 경우보다 유의적으로 낮게 나타났으며, 회계이익의 질에 영향을 주는 변수를 통제한 후에도 이 결과는 여전히 유의 적이면서 일관되었다. 이는 외부감사인 자유선임제도 하에서 경영자에게 제공되는 외부감사인 선임권이 이익조정을 하기 위한 우호적 환경을 제공할 수 있으며 궁극적으로 해당 기업의 회계이익의 질을 저하시키는 요인으로 작용할 수 있다는 사실을 의미한다.

Independence is a factor which has a significant impact on auditing quality, especially in the recent times where the marketplace is increasingly demanding transparency. The independence of auditors is assessed based on the main criteria such as the reliability of the audit opinions, the accuracy, truthfulness of financial reports, and the objectivity in the opinions of the auditor. The study investigates the effects of non-audit services (NAS) on auditor independence in emerging economies such as Vietnam. Non-audit services include taxation services, management advisory services and outsourcing internal audit services. Based on previously relevant researches, the authors develop hypotheses and a regression model about non-audit services (independent variables) and audit independence (dependent variable). The research collects data by 5-scale Likert questionnaire. The findings indicate the relationship between NAS and auditor independence. Specifically, the results reveal two main factors that have influence on auditor independence, namely, taxation services and management advisory services. The results of our research can be considered as new findings and can be compared to previous researches in Vietnam, which establishes a new viewpoint about the relationship between the NAS and the independence of the auditor. This result can be implemented for countries or jurisdictions which are similar to Vietnam.

IS audit has been regarded as contributing to the improvement of the quality of information Systems, recently, it has been argued that it is not possible to expect a effectiveness, because it can offset the schedule burden due to the preparation of additional documents for Audit and it affect to the project schedule. The effectiveness and quality criteria of IS audit are different between groups, because IS audit is responsible for checking the results and process of the developer company. In this study, we modeled between IS effectiveness and auditor competence, audit firm competence, IS audit standards. As a result, it was concluded that auditor competence, audit firm competence, IS audit standards have a positive effect on IS audit effectiveness. However, according to the result of comparing between interest groups, audit firm competence and audit standards were significant in auditor group, but audit standard was significant in requesting organization and developing company thought that auditor was a important factor to audit effectiveness.

To improve audit quality, certain Chinese auditing firms have added a third-level review by an additional signing auditor to the general evaluation by a signing auditor team consisting of an engagement auditor and a partner. Nonetheless, our research-based on 36,033 firm-year observations from 2004 to 2019 reveals that compared to the general review system, auditor teams under the three-level review system are less likely to issue modified audit opinions when abnormal financial conditions arise. This finding suggests that, while larger auditor teams' knowledge, experience, and information advantages can theoretically sharpen their judgment, their performance is more susceptible to interference from divergent opinions, the diffusion of responsibility, and lower energy invested by individual auditors, ultimately impairing their judgment regarding the audited enterprises' abnormal financial conditions. That is, the three-level review system, which aims to improve audit quality, actually worsens audit quality. This conclusion remains valid after the problems of heteroscedasticity and endogeneity are addressed by using firm-level cluster robust standard errors and two-stage regression. We hope that our research will draw the attention of auditing firms, prompting them to reconsider the rationality of the three-level review system.
