Neural network detection of management fraud using published financial data

This paper uses a Artificial Neural Network (AutoNet) to develop a model for detecting management fraud. The study offers an in-depth examination of important publicly available predictors of fraudulent financial statements. We find a model with a high probability of detecting fraudulent financial statements on one sample. The study reinforces the validity and efficiency of AutoNet as a research tool and provides additional empirical evidence regarding the merits of suggested red flags for fraudulent financial statements. © 1998 John Wiley & Sons, Ltd.     

SLEEPWALKING THROUGH SCHOOL: NEW EVIDENCE ON SLEEP AND ACADEMIC ACHIEVEMENT

Policymakers advocating for later school starting times argue that increased sleep duration may generate important schooling benefits. Using data from the National Longitudinal Study of Adolescent Health, this study examines the relationship between sleep duration and academic performance, while carefully controlling for difficult‐to‐measure characteristics at the family and individual levels. We find that increased sleep time is associated with improvements in classroom concentration as well as increased educational attainment. However, we also find evidence of diminishing returns to increased sleep. We estimate an “academic optimum” number of sleep hours of, on average, 8.5 hours per night. Turning to sleep quality, we find that the onset of insomnia‐like symptoms is associated with diminished contemporaneous academic concentration, but little change in long‐run educational attainment.

Ideenwettbewerbe als innovatives Markenbindungsinstrument

Onlinebasierte Ideenwettbewerbe mit Web 2.0-Funktionalit?ten bieten neue innovative M?glichkeiten im Online Marketing. Sie tragen dazu bei, die Bekanntheit und positive Wahrnehmung einer Marke in der ?ffentlichkeit zu st?rken. Konsumenten setzen sich intensiver mit einer Marke auseinander, was schlie?lich zu einer st?rkeren Identifikation mit der Marke und Bindung führt. Auch Swarovski, dem Kristall-Weltmarktführer, gelang durch diese Einbindung von Konsumenten der Erfolg.     

Microfoundations of strategic problem formulation

Before a strategy can be developed, the problem it is supposed to address needs to be formulated. We establish the microfoundations of strategic problem formulation by developing a theory that predicts a core set of impediments to formulation that arise when complex, ill‐structured problems are addressed by heterogeneous teams. These impediments fundamentally constrain and narrow problem formulation, thereby limiting solution search and potential value creation. We establish these impediments as a set of design goals, which, if remedied by an appropriately constructed mechanism, can expand problem formulation to be more comprehensive. Finally, we consider how organizations can improve problem formulation by creating a structured process that satisfies the theoretically derived design goals and detail a specific example of this mechanism (collaborative structured inquiry).

Differences Between Management Philosophies Among American and Chinese Hotel Managers: A Cultural Comparison Between Las Vegas and Shanghai

The aim of this study is to ascertain, in an international tourism context, whether there are cultural discrepancies between hotel employees who have been educated and trained in a host country, and guests who have traveled to that country, given that each group is imbued with their own national culture. The findings indicate that not only do Thai frontline hotel employees have different expectations about the behavior of Japanese and Korean customers, but that the expectations of both customer groups concerning their own behavior differ from those of Thai employees. A significant gap was found in perceptions of actual behavior between the international customers and hotel staff, suggesting that cultural discrepancies are indeed present, but also vary by ethnicity. The scale of the discrepancy between Thai employees’ perceptions of Japanese tourists’ behavior, for example, was larger than in the case of the Korean customers. Comparison of the expectations of the two international customer groups also revealed strong differences.     

Housing,mortgage bailout guarantees and the macro economy

What are the macroeconomic and distributional effects of government bailout guarantees for Government Sponsored Enterprises (e.g., Fannie Mae)? A model with heterogeneous, infinitely lived households and competitive housing and mortgage markets is constructed to evaluate this question. Households can default on their mortgages via foreclosure. The bailout guarantee is a tax-financed mortgage interest rate subsidy. Eliminating this subsidy leads to a large decline in mortgage origination and increases aggregate welfare by 0.5% in consumption equivalent variation, but has little effect on foreclosure rates and housing investment. The interest rate subsidy is a regressive policy: it hurts low-income and low-asset households.     

A Conversation with Kurt Rothschild

Kurt Rothschild was born in Vienna in 1914. In 1938 he came to Glasgow as a refugee from the Nazis, and taught there until his return to Austria in 1947. Between 1947 and 1966 he was a researcher at the Austrian Economic Research Institute in Vienna (WIFO), specialising in labour market and trade issues; he still works for WIFO as a consultant. From 1966 until 1985 he was Professor of Economics at the University of Linz. Two volumes of his collected papers appeared in the 1990s (Rothschild, 1993, 1995). His recent publications include Rothschild (2004a, 2004b, 2006, 2007a, 2007b). This interview took place in Vienna on 1 November 2007.     

Neoliberalism,EU and the Evaluation of Policies

Changes in GDP growth, unemployment and inflation are utilized as indicators of the transition of nineteen OECD countries from Keynesian to neoliberal policies in the period 1960 to 2007. The paper then shows how evaluations of this change and of the success of the European Union can vary depending on the value basis of the observer.     

A Social Cognitive Perspective on the Relationships Between Ethics Education, Moral Attentiveness, and PRESOR

This research examines the relationships between education in business ethics, Reynolds’s (J Appl Psychol 93:1027–1041, 2008) “moral attentiveness” construct, or the extent to which individuals chronically perceive and reflect on morality and moral elements in their experiences, and Singhapakdi et al.’s (J Bus Ethics 15:1131–1140, 1996) measure of perceptions of the role of ethics and social responsibility (PRESOR). Education in business ethics was found to be positively associated with the two identified factors of moral attentiveness, “reflective” and “perceptual” moral attentiveness, and with the PRESOR “stakeholder view” factor. Also, reflective moral attentiveness was found to act as a mediator in the relationship between education in business ethics and the PRESOR stakeholder view factor. Evidence of gender and social desirability bias effects was also found. The implications of these relationships and social cognitive theory for improved understanding of the mechanisms by which a variety of variables have their effects on PRESOR in business are discussed.
