For several decades, most discussion on financial fraud has centered on the fraud triangle, which has evolved over time through various extensions and re-interpretations. While this has served the profession well, the articulation of the human side of the act is indirect and diffused. To address this limitation, this research develops a model to explain the role of human desires, intentions, and actions in indulgence of, or resistance to, the act of financial fraud. Evidence from religion, philosophy, sociology, neurology, behavioral economics, and social psychology is integrated to develop and support an alternative fraud model, called the disposition-based fraud model (DFM). To articulate the model, its two primary components, disposition and temptation, are further developed and extended. Although the DFM is generally applicable to any act of fraud, this paper focuses on executive fraud. The similarities and differences between the DFM and extant fraud models are discussed. Importantly, in light of the DFM, a re-interpretation of the fraud triangle is made to improve our understanding of the human element in it. Additionally, potential implications of the model for corporate governance are discussed, suggestions for further research are offered, and the DFM’s strengths and limitations are noted. 相似文献

This article presents a study of a practical assignment problem found in teaching within higher education. Here, students are assigned to scientific topics for which written papers must be submitted. Often, preferences across topics exist among other side constraints that should be considered in solving the problem of interest. Characterizing attributes of real-world problems were studied for scientific departments in Economics and Business Administration at German universities by sending out 800 questionnaires, and analyzing the 203 responses.Based on earlier studies, a Variable Neighborhood Search (VNS) approach was formulated to solve the resulting assignment problem. Several neighborhood search operators were tested, and numerical results are reported for a range of problem scenarios taken from real-world cases. It was observed that VNS leads to superior results vs. single operator local search approaches. Furthermore, we were able to show that in the studied problem, the effectiveness of certain neighborhoods was, to a large extent, dependent on the structures of the underlying problem.An extension of the problem was formulated by integrating a second objective function, which simultaneously balances the workload of staff members while maximizing student utility. The VNS approach was implemented in a computer system, available free of charge, providing decision support for selected other institutions within higher education. 相似文献

Over the last decades, spatial-interaction models have been increasingly used in economics. However, the development of a sufficiently general asymptotic theory for nonlinear spatial models has been hampered by a lack of relevant central limit theorems (CLTs), uniform laws of large numbers (ULLNs) and pointwise laws of large numbers (LLNs). These limit theorems form the essential building blocks towards developing the asymptotic theory of M-estimators, including maximum likelihood and generalized method of moments estimators. The paper establishes a CLT, ULLN, and LLN for spatial processes or random fields that should be applicable to a broad range of data processes. 相似文献

This research examines two modes of assessment of environmental health risks and the transformation of these risks into public health issues while relying on the specific case of well‐water toxicity and mega dose of electromagnetic radiation found in one prosperous town in the center of Israel – Ramat ha‐Sharon. Based on official and scientific documentation and interviews conducted at three time periods with randomly selected town residents from contaminated neighborhoods (N = 169), this study shows the discrepancy between the ‘objective’ experts’ standards for assessing environmental health risks and the public’s subjective perception and evaluation of the impact of these risks on their health and well‐being. Even though, by experts’ standards, the well‐water toxicity remained constant over the three interview sessions, Ramat ha‐Sharon town residents’ subjective levels of concern and perception of risk fluctuated as a function of news media and municipality announcements and residents’ perceived ability to minimize the risk. This study also shows the complex and multidisciplinary nature of environmental health risk assessments and the need to relocate them into the broader socioeconomic and political context in which they are embedded. 相似文献

We investigate the leverage cycle in Luxembourg’s banking sector using individual bank-level data for the period 2003 Q1–2010 Q1. One of our findings is that Luxembourg’s banks have a procyclical leverage. This procyclicality is not due to marking-to-market but because Luxembourg’s banks are liquidity providers to the EU banking sector. We then empirically investigate the role of bank characteristics as well as real, financial and expectation variables that proxy for macroeconomic conditions in the pre-crisis and crisis period. We find that off-balance sheet exposures have different effects in the pre-crisis and crisis period, and that the share of liquid assets in the portfolio only affects security holdings. As for macroeconomic variables, we find that the Euribor-OIS spread is a significant driver of the build-up in leverage in the pre-crisis period. The reason is that most banks in Luxembourg are either branches or subsidiaries. This makes leverage a less relevant indicator of riskiness for investors. It also implies that in times of liquidity shortages, mother companies or groups demand further liquidity from their branch or subsidiary. The downturn in leverage during the crisis can be accredited to reductions in expectations, which we proxy by an economic sentiment indicator. It can also be explained by increasing bond prices which induce depositors to shift their funds from bank deposits into bonds. We find no important role for GDP growth. 相似文献

Many service classifications have provided helpful yet partial perspectives on the heterogeneity of services. This paper reconciles and integrates different earlier classifications into a new holistic typology of the service economy which is based on detailed statistical service sectors. Moreover, the paper assesses the empirical value of this taxonomy to capture the diversity of services development in time and space. A regional analysis of employment data in Germany provides evidence that knowledge intensive as well as business services follow very different sectoral and spatial dynamics than operational and consumer services. This typology yields differential insights in longitudinal and comparative regional analysis of the service economy. 相似文献

The paper derives a general Central Limit Theorem (CLT) and asymptotic distributions for sample moments related to panel data models with large n. The results allow for the data to be cross sectionally dependent, while at the same time allowing the regressors to be only sequentially rather than strictly exogenous. The setup is sufficiently general to accommodate situations where cross sectional dependence stems from spatial interactions and/or from the presence of common factors. The latter leads to the need for random norming. The limit theorem for sample moments is derived by showing that the moment conditions can be recast such that a martingale difference array central limit theorem can be applied. We prove such a central limit theorem by first extending results for stable convergence in Hall and Heyde (1980) to non-nested martingale arrays relevant for our applications. We illustrate our result by establishing a generalized estimation theory for GMM estimators of a fixed effect panel model without imposing i.i.d. or strict exogeneity conditions. We also discuss a class of Maximum Likelihood (ML) estimators that can be analyzed using our CLT. 相似文献

We forecast portfolio risk for managing dynamic tail risk protection strategies, based on extreme value theory, expectile regression, copula‐GARCH and dynamic generalized autoregressive score models. Utilizing a loss function that overcomes the lack of elicitability for expected shortfall, we propose a novel expected shortfall (and value‐at‐risk) forecast combination approach, which dominates simple and sophisticated standalone models as well as a simple average combination approach in modeling the tail of the portfolio return distribution. While the associated dynamic risk targeting or portfolio insurance strategies provide effective downside protection, the latter strategies suffer less from inferior risk forecasts, given the defensive portfolio insurance mechanics. 相似文献

Audit Fees, Non-Audit Fees and Auditor Going-Concern Reporting Decisions in the United Kingdom 总被引:1,自引:0,他引:1
The accounting profession has come under increased scrutiny over recent years about the growing number of non-audit fees received from audit clients and the possible negative impact of such fees on auditor independence. The argument advanced is that providing substantial amounts of non-audit services to clients may make it more likely that auditors concede to the wishes of the client management when difficult judgments are made. Such concerns are particularly salient in the case of reporting decisions related to going-concern uncertainties for financially stressed clients.
This study empirically examines audit reports provided to financially stressed companies in the United Kingdom and the magnitude of audit and non-audit service fees paid to the company's auditors. We find that the magnitude of both audit fees and non-audit fees are significantly associated with the issuance of a going-concern modified audit opinion. In particular, financially stressed companies with high audit fees are more likely to receive a going-concern modified audit opinion, whereas companies with high non-audit fees are less likely to receive a going-concern modified audit opinion. Additional analyses indicate that the results are generally robust across alternative model and variable specifications. Overall, evidence supports the contention that high non-audit fees have a detrimental effect on going-concern reporting judgments for financially stressed U.K. companies. 相似文献

The hiring of accounting and finance officers from audit firms: how did the market react? 总被引:1,自引:0,他引:1
This study investigates the market’s reaction to companies hiring accounting and finance officers directly from their external
audit firms—the auditor-to-client hiring practice referred to as the “revolving door.” The Sarbanes-Oxley Act (SOX) eliminated this hiring practice, reflecting concerns that such appointments may impair audit and financial reporting
quality. However, it was also argued that companies may have benefited from hiring individuals already familiar with their
systems, organization and personnel. To determine the prevalence of this hiring practice and how shareholders viewed these
appointments, we examine 3-day cumulative abnormal returns around the announcements of newly appointed accounting and finance
officers over the period 1985–2002. We find that the proportion of revolving door hires is relatively low (only 6.1% of all
hires in our sample), but that when they did occur the market valued the revolving door appointments more positively than
other appointments. Further tests reveal that the positive market reaction to revolving door appointments is driven mainly
by smaller companies, and that these appointments are not associated with lower financial reporting quality when assessing
subsequent discretionary accruals or the receipt of an Accounting and Auditing Enforcement Release (AAER). Overall, the low
frequency of occurrence, investors’ positive perceptions, and the lack of association with deteriorated reporting quality
indicate that the SOX restriction on revolving door appointments may have been unnecessary and will do little to protect shareholders.
