The thesis deals with insurance fraud in connection with the economic crisis. The first chapter describes the moral hazard, adverse selection and information asymmetry. Focus on the topic global financial crisis. Further, the concepts fraud and insurance fraud are explained. The main focus of this work is that the financial crisis has led to an increase in insurance fraud and what aspects lead to this fact. The last chapter deals with the procedures of insurance companies, which seek to insurance fraud detection, prevention and repression. This chapter is a description of the settlement of claims, insurance fraud investigation, which includes the characteristics of fraud perpetrators. The last part is dedicated to the prevention and repression of insurance fraud.

The third general standard of fieldwork requires auditors to maintain a skeptical mindset with regards to the collection and critical assessment of audit evidence. While professional skepticism is frequently referenced by professional standards, a lack of precision in defining the concept presumably leads to variation in how skepticism is exercised in practice. Drawing on theories from the fields of psychology, economics and organizational justice, this dissertation considers different perspectives of what constitutes sufficient professional skepticism and examines how those perspectives differ between audit practitioners and regulators. First, I consider competing perspectives of professional skepticism – neutral versus presumptive doubt – and whether asking auditors to adopt alternative perspectives of skepticism may have implications for audit efficiency and effectiveness. While, too little skepticism may endanger audit effectiveness and lead to audit failure or enforcement action, too much skepticism may arguably lead to unnecessary costs and inefficiency. Second, I consider whether the nature of the auditor-client relationship threatens an auditor’s ability to maintain an attitude of professional skepticism. For example, theoretical perspectives from the fields of psychology and economics suggest that auditors may, consciously or unconsciously, be less skeptical of clients with whom they have developed close, positive working relationships or financial dependencies. More specifically, I consider whether skeptical behavior is impeded by management who display low-risk attitudes towards fraud or by client’s who are considered to be highly important to the profitability of the local office. Finally, I examine how professional skepticism is defined from a regulator’s perspective. When a public company is accused of fraudulent financial reporting, regulators may determine iii that the audit performed on the fraudulent financial statements was deficient. Prior research has suggested that in such cases, insufficient skepticism is often a leading cause of alleged audit failure. Within a fairness theory framework, this study examines enforcement actions against auditors between 1999 and 2009, and identifies certain factors that are associated with a citation for a lack of professional skepticism. Overall, results suggest that regulators approach the issue by determining whether auditors should have been more skeptical. Factors found to affect this determination include whether the auditor was perceived as having been aware of an elevated risk of fraud or whether the client was accused of having provided the auditor with false or misleading information during the course of their investigation.

abstract: Due to the growing popularity of the Internet and smart mobile devices, massive data has been produced every day, particularly, more and more users’ online behavior and activities have been digitalized. Making a better usage of the massive data and a better understanding of the user behavior become at the very heart of industrial firms as well as the academia. However, due to the large size and unstructured format of user behavioral data, as well as the heterogeneous nature of individuals, it leveled up the difficulty to identify the SPECIFIC behavior that researchers are looking at, HOW to distinguish, and WHAT is resulting from the behavior. The difference in user behavior comes from different causes; in my dissertation, I am studying three circumstances of behavior that potentially bring in turbulent or detrimental effects, from precursory culture to preparatory strategy and delusory fraudulence. Meanwhile, I have access to the versatile toolkit of analysis: econometrics, quasi-experiment, together with machine learning techniques such as text mining, sentiment analysis, and predictive analytics etc. This study creatively leverages the power of the combined methodologies, and apply it beyond individual level data and network data. This dissertation makes a first step to discover user behavior in the newly boosting contexts. My study conceptualize theoretically and test empirically the effect of cultural values on rating and I find that an individualist cultural background are more likely to lead to deviation and more expression in review behaviors. I also find evidence of strategic behavior that users tend to leverage the reporting to increase the likelihood to maximize the benefits. Moreover, it proposes the features that moderate the preparation behavior. Finally, it introduces a unified and scalable framework for delusory behavior detection that meets the current needs to fully utilize multiple data sources. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2019

This thesis aims to provide a summary overview of instruments of Czech law preventing insolvency petitions of being misused by the creditors and to asses, whether the current legislation provides sufficient protection for borrowers against fraudulent insolvency petitions and on the contrary, whether it does not disproportionately restrict the rights of creditors eligible to enforce their claims towards the borrower in bankruptcy. After the first chapter which defines the basic terms and concepts of the insolvency law, which are used further in the thesis, follows a chapter defining the term "fraudulent insolvency petition" itself and the common motivations of the creditors thereto. The third chapter analyses the particular instruments of private law suitable to provide protection against fraudulent insolvency petitions. The main part of this thesis is contained in the first part of this chapter, which describes the particular instruments of the Insolvency Act providing for protection of borrowers against fraudulent insolvency petitions. The following part of this chapter describes other instruments of private law that might be alternatively used against the fraudulent insolvency petitions. The fourth chapter then describes the criminal law consequences of the fraudulent insolvency petitions. In the...

The ability of auditors to detect fraud, including intentional material misstatements in earnings, remains key to the credibility of audit firms and confidence in capital markets. The PCAOB concludes from its most recent inspections of public company audits that auditors often fail to assess and respond to risks of material misreporting by management. In a behavioral experiment, this study concludes that auditors can increase sensitivity to management motivation to misreport by actively seeking to transform identified risk factors focused on the organization, into factors focused on top managers, and to evaluate whether these manager-focused risk factors represent incentives for personal gain or pressures to avoid a personal loss on the managers. Currently, auditing standards use incentive and pressure as interchangeable constructs, but auditors in this study assess pressure on managers to avoid a loss as a greater risk than an incentive to managers to attain a gain. Results also demonstrate that auditors will be made more sensitive to fraudulent financial reporting risk when focusing on pressure on top managers, than they will be by engaging in a traditional process of assessing total fraud risk based on the three fraud triangle elements. This study is the first to propose a theoretical explanation for why prior studies reflect auditor insensitivity to organizational level fraud risk factors. This study is also the first to enhance knowledge about auditor risk assessment and decision-making through the application of prospect theory and through disaggregation of one of the three elements of the fraud triangle model, by differentiating between incentive and pressure for misreporting earnings.

Diploma thesis is focused on styles, methods and impacts of fraudulent accounting. There is used case -- low of Czech courts because of interpretation and better understanding. The first part of the work attends to basic legal context and Czech economic criminality overview. The main part of thesis introduces crimes, which relate to fraudulent accounting and offenders, who commit these crimes. The end of the thesis deals with analysis of responsibility of particular persons, who are involved in fraudulent accounting.

Dissertation focuse on the internal control system in the enterprises, aims to map the control system by focusing on the purchasing department. I focused on the purchasing process, because with an increasing trends of outsourcing services and the increasing interconnectedness of enterprises increases the risk of fraud currently in the purchasing process. To the research was selected the sample of companies from the banking and non-banking environment, to which were sent a questionnaire focusing on the functionality of the Internal control system in the organization. Banking institutions were chosen mainly because of the strict supervision of the Czech National Bank and the obligations of regular reportin activities are outsourced to supervisory authority, ie the Czech National Bank. Internal control system concept is difficult to define clearly. The main reason is that, in the literature often do not coincide defining the definition of internal control system, and no clear definition of tools, processes and procedures. In Czech Republic is the definition of Internal control system also mentioned in the legislation, and it needs to be understood in very general terms. Schiffer (2009) describes in general terms the Internal control system as a set of operational, financial, personnel, accounting and other controls that are created by management to correct efficient management, compliance with internal rules, asset protection and the most accurate and precise accounting practices in society. Dvoracek (2003) writes that the Internal control system is to be viewed as the sum of interrelated tools, policies, procedures and control mechanisms. In the Czech Republic, for example, contains a definition of the Internal control system Act no. 320/2001 Coll., On financial control in public administration and amending certain laws (Financial Control Act), as amended. Internal control system to be defined as a properly configured system, it must be a grouping of related components and parts, which are gathered into a meaningful whole. Among the elements and parts must be some connection, which is precisely defined.

Fraudulent pages are a danger to which all web users are exposed. These pages have illegitimate purposes such as the theft of sensitive user information. There are a lot of tools available on the market today that are aimed at detecting malicious pages, however, these are not reliable enough and that is why there is still a lot of room for future improvement. Therefore, further analysis of the malicious pages and their characteristics is a key element in protecting users and in the future in eradicating this type of malicious page. A systematic review of the literature has been conducted to generate a list of features that can be used to detect malicious pages and that can ensure a high level of accuracy. During the development of the study, the different articles on the subject have been compared and analysed. For this process of analysis, thematic coding has been used, a qualitative method of analysis, which means that an in-depth understanding of ideas has been pursued. The document presents the already cited list of characteristics as well as offering suggestions and ideas that can be used in the development of future
