This study examines the impact different proxies of agency costs have on companies under different governance approaches. The two specific proxies of agency costs used include: (i) the ratio of operating expenses to annual sales; and (ii) the ratio of annual sales to total assets. Our study is based on earlier works of Ang et al. (2000) and Fleming et al. (2005). A comparison of results for small unlisted companies both in US and Australia indicate that agency cost measures have statistically: (1) different result under rule-based governance mechanisms; and (2) the same results under principle-based governance mechanisms. Our findings support the view that the effectiveness different measures of agency cost is dependent on country specific governance facto as well as on the governance approaches adopted. Our results offer insights to both practitioners and policy makers regarding the usefulness of different proxies of agency costs when companies adopt principle-based corporate governance approaches versus rule-based approaches.

I investigate whether the efficient ratios used as the proxies of the agency costs maintained by Ang et al.(2000) is significant. Utilizing a sample of 77 manufacturing companies listed on the KOSDAQ from the TS2000 of the KSDA, The results are as follows. Agency costs are found to be decreasing with the ownership share of controlling shareholders and accounting performance becomes higher. But firm value measured by Tobin's Q ratio becomes lower according as the ownership of the controlling shareholders increases. If agency costs decrease in proportion to controlling shareholder's share, firm value should be higher according to the agency theory by Jensen and Meckling(I976). But the results of the empirical test of this study are inconsistent with Jensen and Meckling's(1976). Therefore the following study on the more useful proxies stand for agency costs should be needed.

Purpose - This study aimed to identify the effects of ownership structures on agency costs in internationally diversified firms listed on the KOSDAQ market. Design/methodology/approach - A total of 5,824 samples were finally selected and empirically analyzed for a total of nine years from 2011 to 2019, during which the International Accounting Standards had been mandatory for firms listed on the KOSDAQ market. Findings - The results of this study showed that the effects of ownership structures on the ratio of asset turnover are positive for the major share and foreign equity ratios of international diversified firms. Moreover, by selecting the ratio of entertainment expenses as a proxy for agency expenses, this study confirmed that the effects of the ownership structure of an international diversified entity on entertainment expenditure were determined to show a significantly negative relation to entertainment expenditure, thus indicating that the higher the ratio of major shareholders, the more appropriately control the expenditure of entertainment expenses through arbitrary private deviations of the management.Furthermore, considering the effect of the ownership structure on the expenditure of sales and administrative expenses as a proxy variable for agency costs, this study verified that the majority share ratio of international diversified firms was negative to the expenditure of sales and administrative expenses, confirming that the higher the share of major shareholders, the lower the selling and administrative costs, but insignificant.Finally, as a result of determining whether the ownership structure of an international diversified firm affects the holding of free cash, the majority share of this firm shows a significantly negative relation to the ratio of the holding of surplus cash, indicating that the higher the proportion of major shareholders, the more appropriately control the holding of the entity's free cash through arbitrary private deviance by the manager. Research implications or Originality - Major shareholders of an internationally diversified firm listed on the KOSDAQ market play a positive role in the firm's performance by properly controlling agency costs that may be incurred by the management.

The study examines the performance and its relationship with capital structure and agency cost with respect to the industrial configurations and economic groups of Pakistan Economy. The study employs data set of 334 listed joint stock companies from the nonfinancial sectors for the period of 1999-2009 from cotton and textile, engineering, chemical, sugar, cement, fuel and energy, paper and board, transport and communication, and miscellaneous economic groups. Pooled data from the Panel data methodology has been applied to observe the significance of different performance measures through determinant of capital structure and agency costs with special focus on the leverage and cash flows as the direct determinant and interactive variables. The empirical test results using redundant variable tests demonstrate support for agency theory in the context of Pakistan's industrial configurations. The implications of the study point towards more investigations on the subject using industrial configurations as control and moderating variables.

Objectives: The goal of this study was to perform an economic analysis of a primary stenting with drug-eluting stents (DES) compared with bare-metal stents (BMS) in patients with acute myocardial infarction (AMI) admitted through an emergency room (ER) visit in Korea using population-based data. Methods: We employed a cost-minimization method using a decision analytic model with a two-year time period. Model probabilities and costs were obtained from a published systematic review and population-based data from which a retrospective database analysis of the national reimbursement database of Health Insurance Review and Assessment covering 2006 through 2010 was performed. Uncertainty was evaluated using one-way sensitivity analyses and probabilistic sensitivity analyses. Results: Among 513 979 cases with AMI during 2007 and 2008, 24 742 cases underwent stenting procedures and 20 320 patients admitted through an ER visit with primary stenting were identified in the base model. The transition probabilities of DES-to-DES, DES-to-BMS, DES-to-coronary artery bypass graft, and DES-to-balloon were 59.7%, 0.6%, 4.3%, and 35.3%, respectively, among these patients. The average two-year costs of DES and BMS in 2011 Korean won were 11 065 528 won/person and 9 647 647 won/person, respectively. DES resulted in higher costs than BMS by 1 417 882 won/person. The model was highly sensitive to the probability and costs of having no revascularization. Conclusions: Primary stenting with BMS for AMI with an ER visit was shown to be a cost-saving procedure compared with DES in Korea. Caution is needed when applying this finding to patients with a higher level of severity in health status.

최근 국내에 진출한 다국적 기업들의 극명하게 대조되는 행태가 논란이 되고 있다. 본 연구는 해외 명품 패션브랜드 기업들이 높은 본국 배당 송금에 비하여 사회 기부활동 등 사회공헌도가 낮다는 언론 보도에 의하여 유명의류상호 기업들의 대리인 비용을 살펴보고자 하였다. 대리인 비용은 매출액 자산비율(AT), 영업비용 대비 매출액(OPEXP), EBITD 대비 총자산(EBITD)비율을 표본기업별로 구한 값과 2014년 지배구조등급으로 대상을 받은 S-OIL의 비율차이를 각각 구하여 3가지 차이비율의 공통된 속성을 변수를 산정하기 위하여 주성분분석(PCA)으로 공통변수를 추출하고 이 변수를 대리인 비용의 지수변수(ACI)로 선정하였다. 유명의류상호로 선정된 기업을 관심변수로 하고 대리인비용지수(ACI)를 종속변수로 하는 회귀분석을 실시하였다. 분석결과 유명의류상호로 선정된 기업은 판매비와관리비 분야에서 대리인비용이 높게 나타나고 수익성 분야에서 대리인비용이 낮게 나타났다. 그러나 주성분분석에 의한 전체적인 대리인비용은 일반기업과 차이기 나지 않는 것으로 나타났다. 민감도 분석으로 표본집단과 동일한 재무적 특성을 가진 기업들을 PSM방법으로 1:1 matching 표본을 구성하여 비교분석한 결과 판관비 부문에서만 유명의류상호기업의 대리인비용이 높게 나타났다. 추가 분석으로 유명의류상호기업에 국한 하지 않고 211개 산업군에서 브랜드파워 1위로 선정된 기업을 대상으로 대리인비용을 차이를 확인한 결과 본 분석의 결과와 동일한 것으로 나타났다. 본 연구의 결과는 국내에서 최초로 유명의류상호기업의 대리인비용을 분석하여 실증적 결과를 제시하였다는 점에서 의의가 있다고 할 것이다.

본 연구는 내부통제시스템의 평가 및 공개가 기업의 경영자와 지배주주의 대리인 비용에 미치는 영향을 검증하기 위해 SSE상장기업을 대상으로 실증 분석하였다. 대리인 비용은 기업과 이해관계자와의 관계에서 정보의 비대칭으로 나타나는 회계정보의 가치평가에 영향을 주거나, 역 선택으로 나타나는 금융비용을 유발 할 수 있다. 그러므로 대리인 비용은 기업의 가치평가와 회계정보의 신뢰성에 부정적인 요인으로 작용될 수 있다. 따라서 정보비대칭을 감소시키려는 제도와 노력은 대리인 비용을 줄일 수 있다고 볼 수 있다. 기업의 대리인 비용이 적정한 경우 기업의 가치 평가도 상대적으로 양의 방향으로 움직일 수 있다. 본 연구에서는 내부통제시스템의 평가정보가 각각 경영자와 지배주주와의 대리인 비용과의 관계를 분석하기 위해 대용변수로 판매관리비비율과 지분비율을 통해 분석하였다. 또한 통제변수로 독립이사비율, 자본균형 비율, 기업규모 등을 투입하였으며, 분석결과 내부통제의 평가정보는 경영자 및 지배구조에 따른 대리인 비용에 관계가 있는 것으로 나타났다. 본 연구는 SSE상장기업의 내부통제의 평가에 따라 회계정보의 신뢰성 및 기업 가치 평가에 긍정적인 요인으로 작용될 수 있고 향후 관련기업의 회계정보 보고의 절차와 기업의 재무적 환경을 이해하는데 도움이 될 것으로 기대된다.

This research investigates the consequences of the increase in corporate use of short-term debt in China over the past decades. Using a sample of Chinese firms from 2007 to 2018, we empirically explore the effect of corporate use of short-term debt for long-term investment (SFLI) on audit pricing. We first examine the relationship between SFLI and audit pricing for different groups of firms. Then, we investigate the role of the increase in short-term debt in alleviating principal-agent conflicts and reducing agency costs. We have four primary empirical findings. First, auditors tend to charge SFLI clients higher fees. Second, the negative relationship between SFLI and audit fee is found in private firms, firms audited by Chinese domestic auditors, and firms with higher information asymmetry. Third, the time auditors spent on SFLI clients is significantly more than that spent on non-SFLI clients, suggesting that the decrease in audit fee is not due to the decrease in cost. Fourth, SFLI significantly reduces the agency costs of the firm, which auditors regard as a low risk signal and grant an audit fee discount. Our findings suggest that the decrease in debt maturity, not only influences managerial behaviors, but also influences auditors' risk assessment and pricing decisions.

Recently, the demand on the practical application of life-cycle cost effectiveness for design and rehabilitation of civil infrastructure is rapidly growing unprecedentedly in civil engineering practice. Accordingly, it is expected that the life-cycle cost in the 21st century will become a new paradigm for all engineering decision problems in practice. However, in spite of impressive progress in the researches on the LCC, so far, most researches in Koreahave only focused on roadway bridges, which are not applicable to railway bridges. Thus, this paper presents the formulation models and methods for uncertainty-based LCCA for railroad bridges consideringboth objective statistical data available in the agency database of railroad bridges management and subjective data obtained form interviews with experts of the railway agency, which are used to anew uncertainty-based expected maintenance/repair costs including lifetime indirect costs. For reliable assessment of the life-cycle maintenance/repair costs, statistical analysis considering maintenance history data and survey data including the subjective judgments of railway experts on maintenance/management of railroad bridges, are performed to categorize critical maintenance items and associated expected costs and uncertainty-based deterioration models are developed. Finally, the formulation for simulation-based LCC analysis of railway bridges with uncertainty-based deterioration models are applied to the design-decision problem, which is to select an optimal bridge type having minimum Life-Cycle cost among various railway bridges types such as steel plate girder bridge, and prestressed concrete girder bridge in the basic design phase.

This study investigates the factors determining accounting method for R & D costs (capitalize vs. expense) in Korea. Using agency theory and other economic factors, probit and regression models have been developed to distinguish between firms choosing different accounting alternatives for R&D costs. The results are consistent to debt contract, R&D burden and regulation hypotheses both in probit and regression analysis. The size variable has opposite sign in univariate t-test and probit analysis but the signs are mixed and insignificant in regression which may be due to the differences of political environment between Korea and the US. Generally, the results are consistent to those of previous research. The results support the hypothesis that firms with higher leverage and larger burden of R&D costs are more likely to capitalize R&D costs. Partially, larger and regulated firms are more likely to expense R & D costs.
