PE-EDD:An efficient peer-effect-based financial fraud detection approach in publicly traded China firms

Financial fraud arises from the exaggeration of business interests,and an accurate detection or prediction is a useful tool for both corporate management and capital market systems.A collection of computer technologies has been made on this problem so far,and one of the most important solutions is unsupervised learning algorithms.Among them,most approaches work by analysing the internal relations in financial data and finding a new description of non-fraud firms.However,current studies focus a lot on the geometry attribute of financial data,while overlooking the obvious behaviour patterns and peer effects among firms.This has limited the accuracy of representation and furthermore the detection performance.In this work,a very general class of functions is allowed to represent firms,constraining them by peer effects between firms and presenting an error-distribution-based financial fraud firm detection approach.Experimental results have shown great performance of the proposed approach.

Application Technologies and Challenges of Big Data Analytics in Anti-Money Laundering and Financial Fraud Detection

As financial criminal methods become increasingly sophisticated, traditional anti-money laundering and fraud detection approaches face significant challenges. This study focuses on the application technologies and challenges of big data analytics in anti-money laundering and financial fraud detection. The research begins by outlining the evolutionary trends of financial crimes and highlighting the new characteristics of the big data era. Subsequently, it systematically analyzes the application of big data analytics technologies in this field, including machine learning, network analysis, and real-time stream processing. Through case studies, the research demonstrates how these technologies enhance the accuracy and efficiency of anomalous transaction detection. However, the study also identifies challenges faced by big data analytics, such as data quality issues, algorithmic bias, and privacy protection concerns. To address these challenges, the research proposes solutions from both technological and managerial perspectives, including the application of privacy-preserving technologies like federated learning. Finally, the study discusses the development prospects of Regulatory Technology (RegTech), emphasizing the importance of synergy between technological innovation and regulatory policies. This research provides guidance for financial institutions and regulatory bodies in optimizing their anti-money laundering and fraud detection strategies.

Effectiveness of the Financial Ratios in the Determination of the Fraudulent Financial Statements＂ Turkey Practice

Large-scale accounting scandals which were reflected to the world public opinion particularly in the 2000s （such as Enron, Lucent, Xerox, and Parmalat Bank for Reconstruction） carried the matter of fraudulent financial reporting which was made to deceive the financial statement users （Fraudulent Financial Report （FFR）） to the forefront in the agenda of the academicians, operators, and regulatory authorities. As in every crime action, the most effective measure to be taken in preventing FFR events is to try to prevent the FFR before arising. In order to achieve this, in the most effective manner, FFR events should be determined in the formation process. In this study, fraudulent financial statements are tried to be determined by using financial ratios. For this, financial statements of 22 companies which transact in the textile industry in Istanbul Stock Exchange （ISE） were examined. Twenty-three financial ratios were selected for the purpose of determining the risk of fraudulence in the financial statements of the selected companies. These ratios increased in value by multiple regression analysis. The findings which were obtained in the study indicated that some financial statements had the risk of fraudulence. It was concluded that the ratios of inventory/current asset, total debt ratio, and equity turnover rate were a good indicator in the determination of fraudulent financial statements.

Study on how to elevate the discriminating ability of the discriminating model of the financial statement fraud

By summarizing the factor of the financial statement fraud in existing research outcome, the paper confirms the discriminating characteristic of the financial statement fraud and sets up a theoretic model to discriminate the financial statement fraud. Using radial basis function neural network, regarding to the swatch that the listed company that is punished by the Securities Regulatory Commission or the Ministry of Finance, and according to the clustering elements, validating across by set one aside, the paper verifies respectively the 22 characteristics and 31 characteristics of discriminating model. According to the clustering elements, validating across by set one aside, the paper verifies respectively the 31 characteristics and 8 characteristics selected by Fisher-ratio of discriminating model. The research outcome indicates the discriminating ability of the model including 8 characteristics is better elevated than the traditional model including 31 characteristics by comparing the disciplinary error and the forecast precision.

Financial Statements Frauds: Does Their Intensity Have a Connection with Earnings Management?

This study investigates the relationship between earnings management and financial statements frauds.We examine how earnings management practices;done in the two years before the fraud,impact the likelihood of fraud occurrence.Moreover,we introduce a new measure for the fraud intensity.Using a sample of 70 fraud and 70 no-fraud firms,we find that firms committing fraud of higher intensity have managed earnings in the two years before the fraud occurrence.This paper contributes to the literature about fraud antecedents because it is the first study measuring the relationship between earnings management and the intensity of the fraud,and it can be also useful for practitioners,because using the analysis of earnings management practices,analysts can foresee and prevent financial statements frauds.

Positive Research on the Financial Statement Fraud Factors of Listed Companies in China

This paper studied the ＂pressure＂ and ＂opportunity＂ factors that caused financial statement fraud on the basis of the data of 41 A-share listed companies （1999-2004） in China which had been forfeited by China Securities Regulatory Commission （SRC） because of accounting irregularities. The author found that avoiding ＂ST＂ and ＂PT＂ was the primary pressure, and the opportunities mainly came from the higher top 10 shareholders＇ ownership concentration, the lower proportion of independent directors, the fewer number of directorate meetings and shares owned by the directorate members, board chairman and CEO held by one person and the ineffective supervisor boards. We also found that the companies involved financial statement fraud had the lower first majority shareholder＇s share proportion and they changed CPA firm more frequently.

Fraud Identification of Chinese Listed Companies——an Improvement Based on M-Score

To evaluate the applicability of the M-score model in the Chinese capital market,this research observed 190 financial fraud samples punished by the China Securities Regulatory Commission(CSRC)in the years from 2014 to 2018.The test results indicate that two types of errors are high,which means that the applicability of the M-score is unacceptable.Therefore,in this paper,a 9-index model is constructed by Wald's backward stepwise regression method,and the optimal threshold is set by the Beneish expected cost method(ECM).The accuracy of the modified M-score is significantly improved,especially the Type I error rate of is reduced from 70.37%to 19.75%.The receiver operating characteristic(ROC)curve test also proves the superior identification effect of the modified M-score applied in the Chinese market.Finally,variables such as current ratio,fixed asset index,and equity concentration in the modified model could represent the fraud characteristics of Chinese listed companies.

Fraud Prevention Mechanisms of Malaysian Government-Linked Companies： An Assessment of Existence and Effectiveness

Understanding the root causes of fraud and learning about the most effective fraud prevention mechanisms are critical in reducing the incidence of financial fraud. Therefore, this study solicits the views of fraud investigators on the existence and effectiveness of fraud prevention mechanisms within Government-Linked Companies （GLCs）. Specifically, effective fraud prevention mechanisms （FPM） should be undertaken by five critical groups, namely the board of directors, audit committees, external auditors, internal auditors, and anti-fraud specialists. A total of 147 questionnaires were distributed to fraud investigators of all public listed GLCs in Malaysia. Out of those, a total of 45 usable responses were received, which represents an effective response rate of 30.6%. In terms of existence, the respondents ranked ＂management review of internal controls＂ and ＂external audits of financial statements＂ as the top-most FPMs. This was followed by other mechanisms such as operational audits, internal audits and internal control review/improvements by departments. Out of the 27 fraud prevention mechanisms, fraud investigators perceiyed surprise audits, fraud hotline, fraud prevention program and training, anti-fraud policy, fraud vulnerability reviews, operational audits, whistle-blowing policy, internal audit or fraud examination department, and, imposing penalty and disciplinary action as more effective than the others. Overall, this study provides important insights to practitioners and organizations in identifying fraud prevention mechanisms that are most effective.

Review of Financial Pressure

Different from foreign capital markets,china’s domestic capital markets are special,which also determines that the research on financial pressure starts from the reform of state-owned enterprises,and draws lessons from the relevant theories of financial risk and financial fraud,thus gradually forming a more diversified research results.

Principal Model Analysis Based on Bagging PLS and PCA and Its Application in Financial Statement Fraud

Motivated by the Bagging Partial Least Squares(Bagging PLS)and Principal Component Analysis(PCA)algorithms,a novel approach known as Principal Model Analysis(PMA)method is introduced in this paper.In the proposed PMA algorithm,the PCA and the Bagging PLS are combined.In this method,multiple PLS models are trained on sub-training sets,derived from the training set using the random sampling with replacement approach.The regression coefficients of all the sub-PLS models are fused in a joint regression coefficient matrix.The final projection direction is then estimated by performing the PCA on the joint regression coefficient matrix.Subsequently,the proposed PMA method is compared with other traditional dimension reduction methods,such as PLS,Bagging PLS,Linear discriminant analysis(LDA)and PLS-LDA.Experimental results on six public datasets demonstrate that our proposed method consistently outperforms other approaches in terms of classification performance and exhibits greater stability.Additionally,it is employed in the application of financial statement fraud identification.PMA and other five algorithms are utilized to financial statement fraud which concerned by the academic community,and the results indicate that the classification of PMA surpassed that of the other methods.

Similarity measure design for high dimensional data

Information analysis of high dimensional data was carried out through similarity measure application. High dimensional data were considered as the a typical structure. Additionally, overlapped and non-overlapped data were introduced, and similarity measure analysis was also illustrated and compared with conventional similarity measure. As a result, overlapped data comparison was possible to present similarity with conventional similarity measure. Non-overlapped data similarity analysis provided the clue to solve the similarity of high dimensional data. Considering high dimensional data analysis was designed with consideration of neighborhoods information. Conservative and strict solutions were proposed. Proposed similarity measure was applied to express financial fraud among multi dimensional datasets. In illustrative example, financial fraud similarity with respect to age, gender, qualification and job was presented. And with the proposed similarity measure, high dimensional personal data were calculated to evaluate how similar to the financial fraud. Calculation results show that the actual fraud has rather high similarity measure compared to the average, from minimal 0.0609 to maximal 0.1667.

Financial reporting fraud and CEO pay-performance incentives

Because prior studies find mixed results on the relation between CEOs’pay performance incentives and a firm’s likelihood of financial reporting fraud,we restudy their relationship using innovative research methods.First,we concentrate on incentives from granting options rather than equity-based incentives.Second,we emphasize vested options,disregarding unvested option holdings,and take the logarithm transformation of option incentives.Third,we analyse the impact of option incentives on future financial reporting irregularities.Using this innovative approach as well as a full sample and a matched sample,we find that an increase in executives’option incentives raises the likelihood of financial reporting violations.Moreover,the effect of option incentives on financial reporting fraud is moderated by auditor effort.In addition,we find that another proxy for the measurement of executives’option incentives,namely,the number of vested options by executives,is highly correlated with the CEO’s vested stock option sensitivity.

Does the integration between litigation and supervision discipline financial misstatement?

This paper explores the positive governance effects of the Procuratorate’s Public Interest Litigation System in China,which combines the powers of litigationand administrative supervision,on the quality of information disclosure bylisted state-owned enterprises.We report several findings.(1)The likelihoodthat listed state-owned enterprises would issue financial restatements and participate in financial fraud decreased significantly in areas selected for pilotimplementation.(2)The governance effect is stronger in regulated industriesthan in unregulated industries.After the pilot implementation,the agencycosts decreased,and the increase in legal litigation risks related to false statements faced by enterprises played a deterrent effect.(3)The significance of theabove results is stronger when a company’s external and internal governanceare weaker.This study provides both new evidence of the effectiveness of theintegrated governance mechanism and inspiration for future efforts to widelyimplement this mechanism in the capital market.

Creative Accounting Does not Need to Equal Falsification of Accounts

The aim of this paper is to present different aspects of creativity in accounting. Firstly, since creative accounting allows to present a company＇s financial condition in a more favourable light, the ＂advantages＂ of this creativity are identified. This is followed by the enumeration of negative aspects of creative accounting, to illustrate how creativity in accounting may help to falsify the true picture of a company＇s business. Next, the concept of creative accounting and aggressive accounting （the latter, identified rightly, with a financial and accounting fraud） is explained. Finally, methods that are commonly used to falsify accounts, as well as the premises for and the circumstances in which such criminal practices occur, are presented. The paper draws on the results of other scientific works （books and articles published in scientific journals） in which the main and most interesting views of other authors have been presented. A critical analysis method was employed, followed by a comparison of legal texts and legal acts. The scientific conclusion was conducted using the deduction, and, partially, the induction method. It has been shown that it is justified to differentiate in accounting between creativity that is allowable within the established legal limits and practice based upon the use of creativity in a manner contrary to law. Further, it has been concluded that where creativity in accounting goes beyond the limits unambiguously established by the law, it definitely carries attributes of an offence. It has been also noted that due to continuous changes in the functioning conditions of enterprises, the above mentioned limits cannot be fixed or rigid. Thus it is necessary to control and analyse the creativity of accounting and financial staff working in enterprises in order to adapt the binding regulations to the needs of current markets.

Visual analytics for event detection: Focusing on fraud

The detection of anomalous events in huge amounts of data is sought in many domains.For instance,in the context of financial data,the detection of suspicious events is a prerequisite to identify and prevent attempts to defraud.Hence,various financial fraud detection approaches have started to exploit Visual Analytics techniques.However,there is no study available giving a systematic outline of the different approaches in this field to understand common strategies but also differences.Thus,we present a survey of existing approaches of visual fraud detection in order to classify different tasks and solutions,to identify and to propose further research opportunities.In this work,fraud detection solutions are explored through five main domains:banks,the stock market,telecommunication companies,insurance companies,and internal frauds.The selected domains explored in this survey were chosen for sharing similar time-oriented and multivariate data characteristics.In this survey,we(1)analyze the current state of the art in this field;(2)define a categorization scheme covering different application domains,visualization methods,interaction techniques,and analytical methods which are used in the context of fraud detection;(3)describe and discuss each approach according to the proposed scheme;and(4)identify challenges and future research topics.
