The Relationship Between Leaders’ Group-Oriented Values and Follower Identification with and Endorsement of Leaders: The Moderating Role of Leaders’ Group Membership

In this article, we hypothesize that leaders who display group-oriented values (i.e., values that focus on the welfare of the group rather than on the self-interest of the leader) will be evaluated more positively by their followers than leaders who do not display group-oriented values. Importantly, we expected these effects to be more pronounced for leaders who are ingroup members (i.e., stemming from the same social group as their followers) than for leaders who are outgroup members (i.e., leaders stemming from a different social group than their followers). We tested our hypotheses in two studies. Results of a field study (N = 95) showed the expected relationship between leaders’ group-oriented values and followers’ identification with their leaders. A scenario study (N = 137) replicated the results and extended it to followers’ endorsement of their leaders. Overall, these findings suggest that displaying group-oriented values pays off more for ingroup than for outgroup leaders.     

Chancen und Herausforderungen der Rückversicherung in der gesetzlichen Krankenversicherung

In 2009 a so-called morbidity orientated risk structure equalization scheme was installed for the German statutory health insurance in order to minimize structural differences between different providers with respect to revenue and expenditures. Even with this mechanism some risks to the individual health insurance providers remain. Reinsurance could be a way to mitigate these risks, but so far only very few contracts have been signed. Moreover the existing reinsurance contracts only focus on the periphery of the statutory health insurance system such as travel health insurance. In this article we therefore analyse existing risks for individual health insurance providers and evaluate their (re-)insurability. Hereafter the potential for reinsurance solutions in the German statutory health insurance itself as well as in newer forms of healthcare provision (e.g. integrated health care and managed care) is discussed. We find that reinsurance may be a reasonable solution for many of the risks in the statutory health insurance scheme. But as research in this area is very young further analysis of the nature of risks is necessary.     

Hedge-Fonds als Asset-Klasse: Betrachtungen aus der Perspektive der deutschen Versicherungswirtschaft

The over performance of hedge funds until the current financial market turbulences led to a large number of insurers increasing their hedge funds quota. In the following this asset class is examined and particularly analyzed with respect to its adequacy for an insurance company's asset allocation by focusing on the axiom of safety, as demanded by national law. The problem of survivorship-bias and the Markowitz requirements of normal-distribution and constant correlations among the asset classes and their impact on a strategic asset allocation are studied.     

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.     

Pluralismus und versicherung — eine Einführung

Insurance markets and economic financial theory are characterised by a growing diversification and pluralism. A structure is needed to describe the diversification of theory and practice of insurance business. This paper develops such a structure. In addition it shows how new theoretical concepts have lead to new products and new organisational structures on insurance markets. The development in the past decade has shown a close interaction between economic theory and insurance practice. This paper tries to show this interaction by refering to the pluralism of insurance markets.
