Gambling and its impacts in a northeastern Minnesota community: An exploratory study

This exploratory study was undertaken to assess the effects of legalized gambling in a northeastern Minnesota community and to inform the state's citizens and decision makers of the impacts of gambling. The community, the types of gambling available, and the types of businesses and organizations involved in gambling are described. Annual (1990) amounts of money won and lost, profit margins for various types of gambling, and the resulting economic and social community impacts are discussed. The most consequential findings are the amounts of money spent on gambling (twice the state's per capita average) and the resulting community revenue losses (nearly $2 million or $105 per person) annually. Nevertheless, many local citizens want even more gambling opportunities. Public policy and future research issues are raised.     

Investorenreaktionen auf die Fair Value-Bilanzierung von Verbindlichkeiten nach IFRS – eine experimentelle Untersuchung

The fair value-option in IAS 39 allows fair value measurement for liabilities. It is often criticized that a change in a company’s own credit risk affects the value of its liabilities. Therefore it is doubtful whether the fair value-option is in fact useful for investors’ decision making process. Due to a lack of empirical studies concerning the understandability and the decision usefulness of the fair value-option, this paper contains the results of an experimental investigation. We find that investors are misled by fair values for liabilities, though under some circumstances they learn to interpret the financial data correctly. We compare fair value measurement of liabilities with an accounting treatment based on German GAAP.     

Verallgemeinerte DEA-Modelle zur Performanceanalyse

Dyckhoff and Allen derived a generalisation of Data Envelopment Analysis (DEA) in order to measure ecological efficiency. This approach distinguishes between inputs and outputs of an activity on the one hand and their impact on the relevant evaluation criteria—referred to as efforts and benefits—on the other hand. Thereby, the current framework of the DEA for analysing the relative performance of productive units is fundamentally extended. The relevance of this framework is not limited to ecological aspects because many essential problems of DEA application can be solved. Against this background, the paper presents a formalisation of the generalised DEA, applies it to the well-known basic DEA models, and concretises these models for linear effort and benefit functions.     

Prüfungshonorare in Deutschland – Determinanten und Implikationen

The audit fees available since 2005 as a consequence of the Bilanzrechtsreformgesetz (commercial code reform act) show an extremely high supplier concentration on the German audit market of publicly listed companies. This justifies the assumption of audit fees above perfect market equilibrium prices. However, the complete collection and multivariate regression analysis of all relevant audit fee and client data document a 24 % decrease in audit fees in 2005 and an average 15 % decrease in the two subsequent years due to auditor changes. This can be interpreted as an indicator for price competition. In addition, the audit fee data shows that the audit fee decreases are only partially compensated by subsequent increases. As a consequence, there is no evidence for lowballing at present. Further time series are necessary to show if the current trend is sustainable.     

Preis-Promotion-Framing – Ein Überblick zum Stand der Forschung

This article reviews published literature and provides an overview on present empirical evidence about the framing of price promotions. Concerning explicit price reductions (discounts, coupons, rebates), the effects of advertised reference prices and different frames of price discounts (relative versus absolute price discount, objective versus tensile price claims) on consumers’ reactions are discussed. Furthermore, the article examines empirical results on implicit price reductions (volume packs, free extra products) as well as on sale signs and restrictions (e.g. purchase limits, time limits) as popular ways of framing a deal. The key findings point out that framing a price promotion in different ways can affect consumers’ perceptions and evaluations of the deal. Based on the reviewed literature, the concluding section provides managerial implications and an agenda for further research.     

Preis und Qualität als Dimensionen von Kompromissoptionen

This article deals with the question of how consumers cope with decision situations in which a compromise product exists. We examine how the compromise product's position influences choice probabilities. The products we test differ in price and overall quality rating. We present theories, which provide hypotheses on the influence of such types of compromise products and we conduct a new experiment to gain insights into the effects of a compromise product on choice probabilities. The results of the study show that even compromise products with a poor quality/price relation are frequently chosen. The loss in choice probability of the existing products depends on the price category the products belong to.     

Wertschöpfungspotenziale und strategische Implikationen einer Öffnung von Informationsressourcen – Phänomenologie und ein Bezugsrahmen

For some years, companies have successfully harnessed the value-creation potential of external resources by opening up their information resources, thus increasing considerably the value of their own resources. Corresponding phenomena, however, cannot be explained by common resource-based approaches. By providing a structure, our article contributes to a deeper understanding of this issue. We develop a framework, grounded in the Resource-Based View, that differentiates phenomena of opening up information resources between two dimensions: (1) access and (2) control. Our analysis motivates an extended view of information resources management that also accounts for enterprise-external resources. We conceptualize this view as the “management of information spheres,” highlighting the need for further research in the field of value creation related to external resources.     

Humankapitalbewertung bei der BASF Coatings AG – Eine anwendungsorientierte Modifizierung und Operationalisierung der Saarbrücker Formel mit dem Schwerpunkt der Wissensbewertung

The present paper describes the concrete application of an integrated Human capital measurement at BASF Coatings AG. For this purpose the Saarbrücker Formula has been broaden by factors that are of practical relevance. The resulting necessary adjustments in terms of definitions, delimitations and calculation logics of the Saarbrücker Formula lead to the extension and development of the approach. The so generated extended formula enables other companies to evaluate their human capital in a sensible way and to derive personnel-politically measures and therefore to overcome the gap between theory and praxis.     

Gamma shared frailty model based on reversed hazard rate

Abstract

Frailty models are used in survival analysis to account for unobserved heterogeneity in individual risks to disease and death. To analyze bivariate data on related survival times (e.g., matched pairs experiments, twin, or family data), shared frailty models were suggested. Shared frailty models are frequently used to model heterogeneity in survival analysis. The most common shared frailty model is a model in which hazard function is a product of random factor(frailty) and baseline hazard function which is common to all individuals. There are certain assumptions about the baseline distribution and distribution of frailty. In this paper, we introduce shared gamma frailty models with reversed hazard rate. We introduce Bayesian estimation procedure using Markov Chain Monte Carlo (MCMC) technique to estimate the parameters involved in the model. We present a simulation study to compare the true values of the parameters with the estimated values. Also, we apply the proposed model to the Australian twin data set.
