TAX EVASION AND STATE PRODUCTIVITY—AN EXPERIMENTAL STUDY

In an overlapping generations experiment with multiple families participants can support their parents directly and thereby reduce their tax burden or rely on tax‐financed old‐age support. State productivity is captured by the factor with which total tax revenues are multiplied to determine old‐age support. This factor is systematically varied from 0.75 to 1.25. Tax payments depend on declared endowment. Tax evasion is possible, but monitored. Our results suggest that state productivity influences neither direct support of own parents nor tax evasion. The main effect is that rich endowment triggers relatively low support of own parents and high (and more frequent) tax evasion.     

Cross-ownership as a structural explanation for over- and underestimation of default probability

Based on the work of Suzuki, we consider a generalization of Merton’s asset valuation approach in which two firms are linked by cross-ownership of equity and liabilities. Suzuki’s results then provide no arbitrage prices of firm values, which are derivatives of exogenous asset values. In contrast to the Merton model, the assumption of lognormally distributed assets does not result in lognormally distributed firm values, which also affects the corresponding probabilities of default. In a simulation study we see that, depending on the type of cross-ownership, the lognormal model can lead to both over- and underestimation of the actual probability of default of a firm under cross-ownership. In the limit, i.e. if the levels of cross-ownership tend to their maximum possible value, these findings can be shown theoretically as well. Furthermore, we consider the default probability of a firm in general, i.e. without a distributional assumption, and show that the lognormal model is often able to yield only a limited range of probabilities of default, while the actual probabilities may take any value between 0 and 1.     

Sectoral Heterogeneity in New Service Development: An Exploratory Study of Service Types and Success Factors

The service industry is of fundamental relevance for the economies of industrialized countries, as the service industry produces the highest growth in the gross domestic product. In this regard, new service development (NSD) represents a critical resource for competitive survival and a decisive factor of growth in the service industry. However, service firms across many industries are increasingly faced with the challenge of determining how best to manage their development of new service offerings. Although researchers have shown growing interest in NSD issues, this area is still underutilized. Furthermore, although the heterogeneity of the service industry has been emphasized for years, the current body of research on NSD mainly focuses on specific service environments, providing data that are often not comparable across different service sectors. Additionally, there is no study to date that comprehensively examines innovation activities and the relevance of service innovations’ success factors within different service industries. The aim of this exploratory study is to establish a more balanced picture of the nature of innovation activities in terms of NSD characteristics and success factors in the heterogeneous service industry. From this perspective, this paper begins with an examination of the factors that contribute to the success of NSD. Based on a meta‐analysis of new service success factor studies, 17 different success determinants are classified and aggregated to service‐related success determinants. Subsequently, a cluster analysis of 1016 service companies is used to identify different service innovation types. For the service sector, four service innovation types are determined: efficient developers, innovative developers, interactive adopters, and standardized adopters. Furthermore, based on interviews with service innovation managers, the previously identified success factors are examined for each innovation type using a standardized survey. Finally, based on the results of this exploratory study, the paper concludes with recommendations for NSD management and research propositions for each service innovation type. These propositions support innovation managers to successfully manage service innovations for the innovation type they are operating in.     

Raising Capital in an Insurance Oligopoly Market

We consider an oligopoly market where firms offer insurance coverage against a risk characterised by aggregate uncertainty. Firms behave as if they were risk averse for a standard reason of costly external finance. The model consists in a two-stage game where firms choose their internal capital level at stage one and compete on price at stage two. We characterise the subgame perfect Nash equilibria of this game and focus attention on the strategic impact of insurers capital choice. We discuss the model with regard to the insurance industry specificities and regulation.     

Capital Market Development,Competition, Property Rights,and the Value of Insurer Product‐Line Diversification: A Cross‐Country Analysis

In this article, we show that the effect of product diversification on performance is not homogeneous across countries. Diversified insurance companies perform significantly worse than their focused competitors in countries with well‐developed capital markets, high levels of property rights protection, and high levels of competition. In addition, we find that the diversification–performance relationship for insurance companies depends on company size. For large insurers operating in countries with less developed capital markets, diversification significantly increases performance. Our results suggest that the optimal organizational structure may be different for insurers operating in emerging economies than for insurers operating in developed countries.     

Ursachen geschlechtsspezifischer Kostenunterschiede in der Privaten Krankenversicherung: Eine empirische Untersuchung unter besonderer Berücksichtigung der Anforderungen des AGG

The new “Allgemeine Gleichbehandlungsgesetz” (General Equal Treatment Act) also influences the premium calculation of the German Private Health Insurance to antagonize gender discrimination in premiums. The higher premiums in the Private Health Insurance women pay are caused by higher expectation of life, by the risk of fertility, and by higher individual health-care costs for health services. We study how strong the gender influence in health-care costs of men and women are and if they are influenced by the factors mentioned above. We analyse if there is any gender discrimination in premium calculation in the Private Health Insurance. The results show that after eliminating the factors only a small reduction of premiums is found. We still find a cost difference between women and men. This difference can be explained by the different usage of health services but this depends less on the gender rather on individual psychosocial factors.     

Socioemotional wealth and IPO underpricing of family firms

Socioemotional wealth (SEW), i.e., the noneconomic utility a family derives from its ownership position in a firm, is the primary reference point for family firms. Family firms are willing to sacrifice economic gains in order to preserve their noneconomic utility. Thus, we argue that family firms sacrifice IPO proceeds by choosing higher IPO underpricing than nonfamily firms if underpricing helps them protect their SEW. Our empirical results, based on a sample of 153 German IPOs, support our hypothesis. On average, family firms have 10 percentage points more IPO underpricing than nonfamily firms.

Stürzen vorbeugen

Zusammenfassung  Prophylaxen in der Pflege — Je ?lter Menschen sind, desto h?ufiger passieren Stürze. In der Gruppe der über 70-J?hrigen stürzt mehr als ein Drittel mindestens einmal. Eine der gravierensten Folgen dabei der Oberschenkelhalsbruch: In Deutschland sind es bis zu 100.000 Frakturen pro Jahr. Sturz ist damit ein relevanter Kostenfaktor für das Gesundheitswesen.     

Kontrakturen

Zusammenfassung  Prophylaxen in der Pflege — Im Vergleich zu T?nzern haben die meisten Menschen „Kontrakturen“, denn Muskeln und B?nder bleiben nur so lange dehnungsf?hig, wie es für den t?glichen Gebrauch erforderlich ist. Zudem versch?rfen Erkrankungen der Gelenke, Muskeln, Sehnen, B?nder und Narbenzüge das Problem. Kontrakturen sind also ein Ph?nomen, gegen das angegangen werden muss, damit keine Bewegungseinschr?nkungen entstehen.     

On-line/Off-line: Joint Negotiation Teaching in Montreal and Vienna

E-business systems, the most recent generation of information systems, can be effectively used in teaching. One such system was developed and used in a collaborative project that involved teaching of negotiation theory and practice to students from Austria and Canada. The system provides customized course materials and a platform to conduct various e-negotiation activities. The design allows combining e-learning technologies designed to support students in their independent and individual learning with conventional face-to-face training. Our experience indicates that professional negotiation training accompanied by e-learning, and tools to support decision-making and negotiation can foster students' appreciation of the technology as well as demonstrate its limitations. The combination of technology-intensive and conventional resources contributed to students' awareness of social influences on negotiations, importance of communication, and focussed their attention on the problem and its solution. Deeper customization of the course content and delivery may further contribute to effective learning and acquiring of both communication and analytical skills.
