Die Verfahrensheterogenität in der Performance-Messung von Anlageportfolios

Performance measurement is a fundamental part of the evaluation of an asset portfolio. As traditional performance approaches are under severe criticism and their application is widely discussed especially in case of fat-tailed return distributions, modern performance-measures become widely accepted both in academic and practical use. The modern way of an adequate performance measurement is characterized by the application of asymmetric risk measures, by the release of the basic principles of an equilibrium model or by the deflection from a ratio-based construction. Moreover the current academic discussion regarding the combination of modern performance measures and the mathematical construct of copulas leads to copula-based approaches that unify a shortfall-oriented risk-conception with an adequate modelling of dependence structures between the considered portfolio elements. The present paper discusses the main representatives of traditional, modern and copula-based performance measures and shows their advantages and disadvantages as well as possible fields of research.     

Der erste Eindruck zählt!? – Eine empirische Untersuchung von Ankereffekten bei der Vertrauensbildung in elektronischen Verhandlungen

The importance of electronic negotiations for developing and managing interdependent organizational relationships has increased significantly. Due to reduced cues in electronic negotiations interpersonal trust has become a crucial factor to overcome their limitations. Anchoring effects can set the course for trust building processes before any contact between negotiators occurred. So far, these effects have been analysed in face-to-face interactions. We could demonstrate anchoring effects in electronic interactions using internet-based negotiation simulations. We found that the participants quantified their trust level before and after the negotiation according to a priori information about their partners’ trustworthiness. Intuitive evaluations of the other’s trustworthiness seem to act as an anchor that can regulate ensuing perceptions and trust evaluations.

Kundenbindung in Handels- und Serviceunternehmen – Die Wirkung von Kundenbindungsinstrumenten auf Einstellungen und Kaufverhalten

In order to differentiate from their competitors, marketing managers increasingly count on relationship marketing instruments. As customer loyalty programs have gained importance during the last decade, retailers face various new possibilities to reach their customers on a one-to-one level. However, empirical evidence in this field shows that the enormous investments do not always yield the desired effects. One reason is that marketing managers disregard that the effectiveness of different instruments might depend on particular conditions, target groups, and situations. The article gives an overview about the influence of relationship marketing instruments on customers’ attitudes and behaviors. It provides a holistic classification of relationship marketing instruments and explains the effectiveness from a theoretical perspective. We summarize empirical studies dealing with the effectiveness of different instruments under certain conditions. Furthermore, we derive implications for retail managers about how to successfully use relationship marketing instruments. Finally, we discuss directions for future research.     

Beratungserfolg – eine Betrachtung des State of the Art der Ansätze zur Messung und Erklärung des Erfolges von Beratungsleistungen

This paper deals with the actual question of how to measure and to evaluate the success of consulting services. It provides an overview of existing models and concepts concerning the measurement of consulting success and discusses the applicability and limits of these concepts. We show that there are very different perspectives which can be classified according to their research interest and object of investigation. Moreover, we describe their practical implications as well as their limitations. Finally we assess the different perspectives and provide advice on possible future research.

Old flames never die – the role of binding social ties for corporate entrepreneurship in family firms

This paper investigates the role of social ties and family embeddedness for corporate entrepreneurship in family firms. Family firms are mostly characterized by close and often inseparable ties between the dominant family coalition and the firm and offer specific resources within a context of both rational as well as non-rational factors that influence entrepreneurial strategies. We empirically test (n =?181) the relationship between binding social ties and innovation, strategic renewal, and corporate venturing. Our findings indicate a strong significance for networks and close and stable relationships both to inside the firm and the outside in decision making for corporate venturing and innovation. In contrast, the results for strategic renewal show no relevance of strong social ties. We link up with the debate on the role of owners as an important stakeholder group.
