As managing customer relationship gets more important, companies are strengthening information service using multi-channels to their customers as a part of their customer relationship management (CRM) initiatives. It means companies are now accepting such information services not as simple information -delivering tools, but as strategic initiatives for acquiring and maintaining customer loyalty. In this paper, we attempt to validate whether or not such various information services would impact on organizational performance in terms of CRM strategy. More specifically, our research objective is to answer the next three questions: first, how to construct the instruments to measure not information quality but information service quality?; second, which attributes of information service quality can influence corporate image and customer loyalty?; finally, does each information service type have unique characteristics compared with others in terms of influencing corporate image and customer loyalty? With respect to providing answers to those questions, the previous studies had been limited in that those studies failed to consider the variety of types of information service or restricted the quality of information service to information quality. An appropriate research model answering the above questions should consider the fact that most companies are utilizing multi channels for their information services, and include the recent strategic information service such as customer online community. Moreover, since corporate information service could be regarded as a type of products or services delivered to customer, it is necessary to adopt the criteria for assessing customer's perceived value when to measure the quality of information service. Therefore, considering both multi-channels and multi-traits may enable us to tell the detailed causal routes showing which quality attributes of which information service would affect corporate image and customer loyalty. As information service channels, we include not only homepage and DM (direct mail), which are the most frequently applied information service channels, but also online community, which is getting more strategic importance in recent years. With respect to information service quality, we abstract information quality, convenience of information service, and timeliness of information service through a wide range of relevant literature reviews. As our dependant variables, we consider corporate image and customer loyalty that both of them are the critical determinants of organizational performance, and also attempt to grasp the relationship between the two constructs. We conducted a huge online survey at the homepage of one of representative dairy companies in Korea, and gathered 367 valid samples from 407 customers. The reliability and validity of our measurements were tested by using Cronbach's alpha coefficient and principal factor analysis respectively, and seven hypotheses were tested through performing correlation test and multiple regression analysis. The results from data analysis demonstrated that timeliness and convenience of homepage have positive effects on both corporate image and customer loyalty. In terms of DM, its' information quality was represented to influence both corporate image and customer loyalty, but we found its' convenience have a positive effect only on corporate image. With respect to online community, we found its timeliness contribute significantly both to corporate image and customer loyalty. Finally, as we expected, corporate image was revealed to provide a great influence to customer loyalty. This paper provides several academic and practical implications. Firstly, we think our research reinforces CRM literatures by developing the instruments for measuring information service quality. The previous relevant studies have mainly depended on the measurements of information quality or service quality which were developed independently. Secondly, the fact

발생액의 질의 회계정보 유용성

손성규,고재민,백혜원 한국회계정보학회 2009 회계정보연구 Vol.27 No.2

The objective of this study is to investigate whether accruals quality, an alternative measure of accounting information quality, has an information content in the capital market. Traditionally discretionary accruals are used as a proxy of accounting information quality. However, discretionary accruals might imply earnings management or deliver managers' private information. Thus the discretionary accruals could cause a measurement error problem. Dechow and Dichev(2002) argued that discretionary accruals which are realized into future cash flows cannot be a outcome of earnings management but a signal of future performance. In this perspective, accruals quality measured with cash flows of previous, current, and next period is considered to overcome the measurement error of discretionary accruals. The superior accounting information would accompany bigger stock price reaction by its predictability and precision, and smaller trading volume reaction by mitigating the heterogeneity among investors. In order to test an information content, we examine if stock price reaction is bigger and trading volume reaction is smaller as accruals quality increases. In addition, we compare an information content of accruals quality with that of discretionary accruals. This will enable us to recognize which measure is more effective in judging quality of accounting information in the capital market. Our empirical results are as follows. First, the higher the accruals quality, the bigger the stock price reaction with the same unexpected earnings. Second, the higher the accruals quality, the smaller the trading volume reaction with the same stock price change. Third, stock price reacts more and trading volume reacts less in superior accounting information assessed by accruals quality than discretionary accruals. Our findings show that accruals quality is a significant measure of accounting information quality. Furthermore, it could be a better proxy of accounting information quality than discretionary accruals in the capital market. Therefore, we suggest that researchers should use accruals quality in valuing quality of accounting information. 본 연구의 목적은 발생액의 질(accruals quality)이 회계정보의 질을 평가하는 측정치(proxy)로 적정한지를 검증하는 것이다. 즉 발생액의 질이 자본시장에서 어떻게 평가 받는지를 분석함으로써, 정보유용성이 있는지를 살펴보는 것이다. 전통적인 측정치인 재량적발생액이 사적 정보의 전달과 이익조정의 수단이라는 양면성을 가지고 있기 때문에, 재량적발생액의 크기만으로 회계정보의 품질을 평가하는 것은 논란의 여지가 있다. Dechow and Dichev(2002)는 재량적발생액이라도 실제로 현금으로 실현되는지 여부에 따라 회계정보의 질을 평가함으로써, 재량적발생액이 갖는 측정 오차를 극복하고자 하였다. 양질의 회계정보는 이익 공시 시점에서 높은 예측 가능성(predictability)과 정확성(precision)으로 주가 반응은 클 것이며, 회계정보 해석의 이질성(heterogeneity)을 완화시켜 거래량 반응은 작을 것이다. 따라서 발생액의 질에 따라 회계이익이 주가수익률에 미치는 영향과 주가 변동이 주식 거래량에 미치는 영향이 어떻게 달라지는지를 살펴보았다. 또한 회계정보의 질에 대한 전통적인 측정치인 재량적발생액과 발생액의 질에 대해 주가 반응과 거래량 반응을 비교함으로써, 회계정보의 질을 평가하는 데 있어 어떤 측정치가 시장에서 더 유효한지를 검증하였다. 실증 분석 결과는 다음과 같다. 첫째, 같은 비기대이익 수준이라 하더라도 발생액의 질이 높은 기업은 주가 반응이 더 크게 나타났다. 둘째, 주가 변동의 정도가 같더라도 발생액의 질이 높은 기업은 거래량 반응이 더 작다는 사실을 확인하였다. 셋째, 재량적발생액보다 발생액의 질로 평가한 양질의 회계정보에서 주가 반응은 더 크고 거래량 반응은 더 작다는 사실을 관찰하였다. 이는 발생액의 질은 자본시장에서 회계정보의 질을 평가하는 유효한 측정치로 인정 받고 있으며, 재량적발생액보다 더 의미 있는 측정치로 평가 받고 있음을 의미한다. 따라서 향후 자본시장 연구에서 회계정보의 질을 평가할 때는 재량적발생액 뿐 아니라, 발생액의 질을 적극적으로 도입하는 것이 필요하다고 제안한다.

Purpose: This study is addressing the establishment of the knowledge information system supplying the quality management of weapon system. It is going to support the continuous quality management through the linkages and integration between the product structure and the quality information. Methods: The interrelated relationship of the product structure information and quality information of weapon system would be expressed explicitly by taking advantage of the ontology concept. The quality information of distributed systems would be integrated through the SOA(Service Oriented Architecture)-based Web services. After defining the inference rules, which could be utilized in the quality management, in the constructed knowledge information system, the quality information would be inferred through the queries. Results: By building the integrated quality information knowledge system through the ontology and SOA, the connectivity between the product structures and dispersed quality information was enhanced. The utility and applicability of this study were checked up through the inferences on the products and quality information by using the information built by the semantic relationship of facts. Conclusion: We established the knowledge and information system as a systematic approach to support the quality management of weapon system. This is not affected by the organizations and systems, and it seems that it could be utilized across the quality management as the efficient knowledge sharing architecture support-ing the quality management of weapon systems in the aspect of the product integration.

산업별 회계정보의 품질에 대한 실증연구

김성환 ( Sung Hwan Kim ),손성규 ( Sung Kyu Sohn ) 한국회계학회 2011 會計學硏究 Vol.36 No.3

본 연구는 기업이 사업을 영위하고 있는 환경으로서의 산업이 기업의 회계정보 품질을 설명하는 중요한 요인이 될 수 있는가에 대한 질문에 답을 하고자 하였다. 이를 위해 2000년부터 2007년까지 유가증권시장과 코스닥시장에 상장되어 있는 기업들을 대상으로 회계정보 품질 측정치를 활용해 산업별 회계정보 품질 차이를 실증하였다. 실증결과 산업 차원에서 회계정보 품질의 차이가 존재하며 산업 요소가 회계정보 품질 차이에 미치는 영향도 상대적으로 크다는 사실을 확인할 수 있었다. 이를 통해 다른 사회과학분야에서 산업별로 조직형태, 전략수립, 자본구조 등 기업의 특성이 유사해지는 현상이 회계분야에서도 나타나고 있음을 알 수 있다. 그리고 산업별 특성이 존재한다는 재무회계 분야의 통념에 대한 실증적 증거를 제시하였다. 또한 산업별로 회계정보의 질적 속성이 상이하다는 실증적 증거를 통해 산업별전문 감사인의 중요성을 재차 확인할 수 있었다. 본 연구는 경쟁 환경, 기술 환경, 사업의 영위 형태 등 산업 차원의 특성이 기업의 회계품질차이를 초래하고 있음을 실증하였다. 그 결과 경쟁 정도가 높은 산업에서 회계정보 품질이높게 나타났다. 경쟁 정도와 회계정보 품질 간의 인과 관계를 보다 명확히 하기 위해 추가분석을 하였는바, 경쟁 정도가 낮은 독과점 산업에서 규제기관의 주의를 끌지 않기 위해서 수익성이 높을 경우 이익을 하향 조정하는 현상을 확인하였다. 첨단기술 산업의 경우 회계정보 품질이 낮게 나타났다. 그 이유는 첨단기술 산업의 경우 감사인 및 투자자들이 기술과 관련되어 이해와 전망이 어렵기 때문에 경영자의 재량적 판단이 더 많이 개입되었기 때문이라고 생각된다. 사업의 영위 형태와 관련되어서는 수주형 산업에서 회계정보 품질이 낮고, 규제산업에서 회계정보 품질이 높은 것으로 나타났다. 이는 수주형 산업의 경우 진행기준 적용과정에서 경영자의 재량적 판단이 개입될 가능성이 있는 반면, 규제 산업의 경우 요금 산정에 기초가 되는 재무자료가 규제기관으로부터 지속적으로 관찰되어 이익 조정이 상대적으로 힘들기 때문인 것으로 추측된다. 이러한 분석 결과는 국가, 기업 차원에 추가하여 산업 차원에서도 기업의 회계품질에 영향을 미치는 요인을 구체적으로 찾아낸 것으로서, 개별 기업의 회계정보 품질을 추정할 때 산업의 특성까지 종합적으로 고려해야 한다는 시사점을 제시한다. 그리고 산업별 특성을 고려한 회계정보 품질의 제고 방안을 모색할 필요가 있다는 점을 제안한다. 또한 회계정보 품질이 낮은 산업에 대해서 선별적으로 감리를 더욱 강화하고, 보다 엄격한 내부통제 제도를 갖추도록하는 제도적 보완이 필요하다는 것을 의미한다. 산업별 특성을 추가적으로 고려한 감사가 이루어질 수 있도록 감사인의 산업전문성을 제고시키기 위한 제도적 노력 역시 필요하다는 것을 시사한다. The purpose of this study is to provide an answer to whether industry as the business environment is a main factor determining accounting information quality of individual corporations. The sample of this study covers firms having December fiscal year from year 2000 to 2007 listed in either the Korea Stock Exchange or KOSDAQ markets. I investigate whether there are differences in accounting information quality among industries using two metrics of accounting information quality. Empirical results show that there are differences in accounting quality among industries. From these results, I find that corporations in the same industry have similar accounting information quality as shown in the patterns of other social sciences studies. And applying the theory of other social science to financial accounting can enhance the understandings of corporate accounting information disclosure behaviors. These results also provide clear empirical evidence concerning common notions about industrial characteristics. As for the audit research, these results can confirm the importance of industry-specialized auditors. I then endeavor to demonstrate whether there are industrial characteristics that cause differences in accounting information quality of an industry. I classified industrial characteristics into competition environment, technological environment, and types of business operation and examined the effect of industrial characteristics on accounting information quality. The empirical result indicates that accounting quality improves in competitive industry. To investigate more closely the causality between the degree of competition in industry and accounting information quality, the accounting quality in the industry where competition is limited is observed. The firms in the industry which the regulatory bodies perceive as monopolistic or oligopolistic have low accounting quality. When high profitability is reported, a regulatory agency may think it is due to the problem of monopoly, leading to income-decreasing earnings management. I conclude that accounting quality improve as the competition increase, because firms in the industry which regulatory agent perceive as monopolistic manipulate earnings so as to circumvent restrictions of a regulatory agent. As for high-tech industry, accounting quality is low. From these empirical results, I can infer that when the technology researched and developed is cutting edge, manager`s discretionary estimation has more impact on the accounting procedure, and the manager can manage earnings more easily. As for the type of business operation, contracting industry has low accounting quality. Regulated industry has high accounting quality. In contracting industry, the manager`s discretionary estimation(or judgement) can influence the accounting procedure much more. Firms in a regulated industry maintain high accounting quality due to continuous monitoring of a regulatory agency. These results contribute to finding out the main causes that affect accounting information quality at the industry level. And these results provide caution for accounting information users to consider industrial characteristics together in estimating accounting quality of individual companies. This study suggests that regulatory agencies should take steps to improve the accounting information quality by considering industrial characteristics. To be more precise, differentiated plans by industry should be applied to enhance accounting quality for the industries where competition is limited, high-technology is used, and so on. In the year 2011, Korean listed companies should report financial statement in accordance with IFRS (International Financial Reporting Standards). IFRS complies with a principle-based approach, and it does not suggest an industrial accounting standard that classify by type of business. Since Korean companies are accustomed to rule-based accounting standards, they can be confused by adopting the principle-based approach that there are possibilities to imitate the accounting practices of other companies in the same industry. Therefore, this paper lays out a logical basis for establishing industry accounting standards classified by types of business (working-level guideline) that reflects the economic substance of the industry. This paper also raises the necessity of the institutional complements like selective audit review or strict internal accounting control systems for the industries showing low accounting quality. And this study proposes that systemic efforts to enhance the industry expertise of auditors should be made. For example a check list in audit quality review including an audit manual classified by industry, industry expertise training and so on.

신형섭 ( Hyung Sup Shin ),한경훈 ( Kyoung Hoon Han ) 한국호텔리조트카지노산학학회 2005 호텔리조트연구 Vol.4 No.2

Because of rapid changes on the economic environment and the strong competition, the existing hotel service business makes steady progress from the simple decision-making and reporting to strengthening the competitiveness by supporting the hotel business. In hotel service, efficient information system has to be established and utilized to cope with opening service market through diversifying service and reconsidering competitiveness. But in hotel service, the establishing and utilizing information system relatively fall behind profit-enterprise, and study for the performance model about information system used in hotel service business is not enough yet. The purpose of this study is how the information system has been efficiently utilizing in hotel service in Korea and analyzing the actual status of utilizing information system in hotel service, and verifying whether information system quality variables (system quality, information quality, service quality)by mediation variables, have influence on the user satisfaction of the information system. For this purpose, information system quality variables(system quality, information quality, service quality) are chosen from the existing study to use questionnaire. Result of this study, the hotel service business in Korea are easy to operate and manage and to fit into a new environment change on system quality, have the asked information believing and exacting on information quality, and satisfy the supports and the staff`s ability of the service company on service quality. Therefore hotel information system quality variables have the effect on the performance of system.

본질적⋅재량적 발생액의 질과 정보비대칭의 관계: 재무분석가의 역할을 중심으로

김정모 한국회계학회 2024 회계저널 Vol.33 No.2

본 연구는 회계정보의 질과 정보비대칭 사이의 관계, 이에 대한 재무분석가의 영향을 조사한다. 구체적으로 불량한 본질적⋅재량적 발생액의질이 정보비대칭을 심화하는지, 그리고 재무분석가들이 이를 효과적으로 억제하는지 조사하였다. 2012년부터 2020년까지의 국내 비금융상장사를대상으로 bid-ask 스프레드로 정보비대칭을 측정하고 총발생액, 본질적⋅재량적 발생액의 질로 회계정보의 질을 측정하여 분석한 결과는 다음과같다. 첫째, 불량한 발생액의 질은 정보비대칭을 심화시키며, 본질적 발생액의 질이 이러한 관계를 견인한다. 둘째, 추종 재무분석가의 존재는 불량한 총발생액의 질, 특히 불량한 본질적 발생액의 질로 인한 정보비대칭의 심화를 효과적으로 억제한다. 자기선택편의를 통제한 분석, 대안 종속변수를 사용한 분석, 시장별 분석 결과에서도 유사한 결과가 관찰되었다. 회계정보의 질이 불량할수록 정보비대칭은 심화하며, 이는 재무제표를 이용하는 정보이용자들에게 제약으로 작용한다. 본 연구의 실증분석 결과는 불량한 회계정보의 질로 인한 정보비대칭의 심화를 억제한다는 점에서 재무분석가들은 자본시장에서 정보매개자를 넘어 정보제공자의 역할, 그리고 기업의 외부지배구조 역할을 한다는 점을 제시한다. 또한, 선행연구는 재량적 발생액의 질보다는 본질적 발생액의 질이 불량한 경우 추종 재무분석가가 증가하는 경향을 보고한 바 있다. 이와 관련하여 본 연구는 재무분석가는 불량한 본질적 발생액의 질로 인해 심화하는 정보비대칭을 억제하는 역할을 수행한다는 점을 제시한다. 따라서 본 연구는 정보비대칭과 회계정보의 질의 관계, 그리고 이에 대한 재무분석가의 역할에 대한 선행연구를 자본시장 관점에서 확장한다. This study investigates the relationship between accounting information quality and information asymmetry and the role of financial analysts in the relationship. Specifically, this study tested whether financial analysts effectively suppress information asymmetry arising from the innate and discretionary accruals. Using non-financial Korean listed companies from 2012 to 2020, measuring the information asymmetry by bid-ask spreads, and measuring the accounting information quality as accruals quality, this paper provides the following findings: First, the poor accruals quality intensifies information asymmetry, and in particular, the innate accruals quality drives the relationship. Second, analysts play an important role in suppressing the deepening of information asymmetry due to poor innate accruals quality. This study has the following contributions. The poorer the quality of accruals, the more severe the information asymmetry, which can be a constraint to accounting information users. As analysts alleviate the deterioration of information asymmetry arising from poor accounting information quality, analysts play the role of information providers beyond information intermediaries in the capital market as well as the role of external governance mechanisms. Furthermore, prior studies suggest that the number of following financial analysts increases when the quality of innate accruals is poor. In this regard, this study suggests that analysts mitigate the information asymmetry deterioration due to the poor innate accruals quality. Therefore, this study shed light on the role of financial analysts in accounting information quality and information asymmetry from the capital market perspective.

Dietary and herbal supplements for fatigue: A quality assessment of online consumer health information

Jeremy Y. Ng,Catherine Jiayi Zhang,Saad Ahmed 한국한의학연구원 2021 Integrative Medicine Research Vol.10 No.4

Background The Internet is increasingly utilized by patients to acquire information about dietary and herbal supplements (DHSs). Previously published studies assessing the quality of websites providing consumer health information about DHSs have been found to contain inaccuracies and misinformation that may compromise patient safety.. The present study assessed the quality of online DHSs consumer health information for fatigue. Methods Six unique search terms were searched on Google, each relating to fatigue and DHSs, across four countries. Across 480 websites identified, 48 were deemed eligible and were quality assessed using the DISCERN instrument, a standardized index of the quality of consumer health information. Results Across 48 eligible websites, the mean summed score was 47.64 (SD = 10.38) and the mean overall rating was 3.06 (SD = 0.90). Commercial sites were the most numerous in quantity, but contained information of the poorest quality. In general, websites lacked discussion surrounding uncertainty of information, describing what would happen if no treatment was used, and how treatment choices affect overall quality of life. Conclusion Physicians and other healthcare professionals should be aware of the high variability in the quality of online information regarding the use of DHSs for fatigue and facilitate open communication with patients to guide them towards reliable online sources.

< 연구논문 > : 이익의 질이 회계정보를 이용한 가치평가에 미치는 차별적 효과: 이익특성변수들 간의 비교

김경순 ( Kyung Soon Kim ),이진훤(교신저자) ( Jin Hwon Lee ) 한국회계학회 2016 회계저널 Vol.25 No.2

본 연구는 회계이익의 품질이 개별기업의 고유정보위험을 대리할 수 있다는 선행연구에 기초하여, 다양한 이익특성변수들이 회계정보를 이용한 가치평가의 유용성(가치관련성)에 미치는 효과를 분석한다. 특히 한국주식시장에서 다양한 이익특성변수들 중 어떤 이익특성변수가 회계정보를 이용한 가치평가와 민감한 관계를 갖는지를 분석함으로써 투자자들이 정보위험으로 인한 가치평가 오류 가능성을 축소시킬 수 있는 효과적인 도구를 찾는데 초점을 맞추었다. 이를 위해 2003년부터 2012년까지 유가증권시장과 코스닥시장에 상장된 11,243개의 기업-연도 표본을 대상으로 Ohlson(1995)의 단순모형을 이용하여 가치관련성의 강도를 측정한다. 그 다음에 발생액의 질, 이익지속성, 예측가능성, 이익유연화, 재무투명성, 적시성, 보수성, 재량적 발생액의 절대값 등 여덟 가지 이익특성변수들을 계산하여 가치관련성에 미치는 효과를 조사한다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 긍정적인 이익특성을 갖는 기업에서 회계정보의 가치관련성은 증가하였다. 이는 투자자들이 정보위험을 감소시키기 위해 이익의 질이 높은 기업일수록 회계정보를 주식가치 평가에 더 많이 반영하고 있음을 의미하고 있다. 둘째, 여덟 가지 이익특성변수 중 발생액의 질이 가치관련성과 가장 민감한 관계를 나타냈다. 이는 Francis et al.(2004)의 연구와 유사한 결과로써 한국주식시장에서도 발생액의 질이 개별기업의 정보위험(대리인 위험)을 포착할 수 있는 유용한 대리변수일 가능성을 시사하고 있다. 셋째, 기업의 사업구조와 영업환경에 의해 발생한 선천적 위험요인(innate risk factor)을 통제하고 분석한 결과, 여전히 발생액의 질과 이익유연화가 가치관련성에 긍정적인 효과를 발생시켰다. 이는 Ohlson 모형을 이용한 가치평가의 유용성은 이익특성에 내재된 재량적 요인(discretionary factor)에 의해 영향을 받을 수 있음을 제시하는 결과이며 동시에 이익특성에 내재된 경영자의 재량적 요인이 정보위험을 측정하는 중요한 요소가 될 수 있음을 시사하고 있다. We examine the association between various attributes of accounting earnings and value relevance. Based on the result of prior research that earnings quality can predict firm-specific information risk, we test if it is also observed in Korean stock market. Specifically, we analyze that which variable is sensitively related in value relevance among various earnings attributes. Our research contributes to find effective tool for minimizing valuation error caused by information risk. In detail, this research focus on as in below. First, we determine the relation of value relevance with measurement perspective and firm-specific information risk caused by information asymmetry between manager and external investors. In particular, we compare which earnings attributes effect more to value relevance reflecting information risk in a similar way of Francis et al.(2004) which analyzed the relation between earnings attributes and cost of equity capital. We estimated value relevance and earnings attributes using the similar way used in Frankel et al.(2006) and Francis et al.(2004) each. Earnings attributes are usually categorized as (1) accounting-based and (2) market-based. We refer to accrual quality, persistence, predictability, smoothness and discretionary accrual as accounting-based. These attributes measured time-series and cross-sectional analysis using accounting information only. We refer to financial transparency, timeliness and conservatism as market-based. These attributes take stock return or prices as the reference construct; consequently, measures of these attributes are based on the estimated relation between accounting earnings and stock prices or returns. In fact, the purpose of this research is that which earnings attributes effectively reflect information risk that exists between manager and external investors comparing the earnings attributes`s sensitivity to value relevance. Secondly, we investigate whether discretionary factor can be used in estimating the manager`s agency risk by analysing the discretionary factor`s effect to value relevance. The earnings attributes we considered are jointly determined by innate factors, such as firms business models and operating environments, and by management`s discretionary reporting. However, information risk is observed by discretionary factor of earnings attributes since it is usually occurred by manager`s opportunistic motive. Therefore, we analyze the incremental effect of discretionary factor from earnings attributes determining the relation of earnings attributes and value relevance after controlling the innate factor in operating activity. Drawing on 11,243 firms listed on KOSPI and KOSDAQ of KRX from 2003 to 2012, we examine the relationship between value relevance and earnings attributes. The results are as in below. First, accrual quality and earnings smoothness are positively associated with value relevance. Thus, the earnings attributes from accounting information can effect on investors`s pricing. Secondly, as a result, accrual quality has the most significant association with value relevance among the eight variables. It refers that accrual quality can be the useful proxy which shows firm`s information risk in Korean stock market. Thirdly, the relation between accrual quality and earnings smoothness also shows positive relationship in the test even after controlling the innate factors occurred by firm`s business models and operating environments. Furthermore, we analyze the effect on value relevance after categorizing accrual quality as factors occurred by manager`s discretion and innate factors in operating activity and we found that as discretionary accruals quality gets lower, valuation error used accounting information gets decreased. This result provides implication as follows. There are possibilities that information asymmetry could exist between manager and external investors. Moreover, manager provides biased accounting information using discretionary factor to get his private benefit. Thus, in case of using the model in pricing, there is a risk of investor`s adverse selection by information risk from accounting information. This research analyzes the effect of various earnings attributes to the pricing using accounting information and we believe that it will minimize the adverse selection risk in case of pricing with Ohlson model. Secondly, Francis et al.(2004) measured the estimator of ex ante cost of equity using analyst`s forecast data and studied the association between earnings quality and cost of equity. However, in Korean stock market, the analysts tend not to analyze many firms and provide long-term target price, and it may cause optimistic bias. Thus, it may be hard to analyze the earnings attributes effect with measurement of the ex ante cost of equity in Korean stock market as in Francis et al.(2004). Therefore, we do not investigate the direct relationship between earnings attributes and cost of equity as in the prior studies. Instead of that, we test it indirectly through the relationship between earnings attributes and value relevance. Through this way, our study measures the value relevance and earnings attributes, and we analyze the relation of all the listed firms. Even we test it indirectly, we believe that the result is meaningful regard to verifying that earnings quality can be a useful proxy of information risk. Thirdly, we also believe that this research provides earnings attributes that effect on pricing and which do not effect by comparing various earnings attributes to value relevance after controlling innate factors which occur in operating activity. We conclude that discretionary accruals quality has more pronounced value relevance than other attributes and this result is similar to Francis et al.(2004, 2005). That means discretionary accruals quality is helpful as the most proper proxy of information risk in Korean stock market. Thus, we believe that discretionary accruals quality is useful as an efficient proxy of information risk regarding to the relevant information risk study in Korean stock market.
