Die Rezeption (Thyssen-)preisgekr?nter Artikel in der ?Scientific Community“

We investigate whether journal articles winning a prestigious award of the Thyssen foundation have a higher impact in the scientific literature than a control group of non-awarded articles. In average, awarded articles harvest significantly more citations than articles in the control group. Most remarkably, the average citation rank exactly matches the rank order of awards. The top award earns most citations while the second award, the third award and the non-awarded articles exhibit citation counts in declining order. The correlation of award rank and impact does not vanish if we restrict citation counts to the year of publication and the year thereafter. In this time span the distinction of excellence is very unlikely having a genuine effect on the impact measure. Thus, we do not find support for the social constructivist hypothesis that the correlation of the jury decision and the article impact is explainable by a label of distinctiveness. On the contrary, the empirical data confirm that the jury is successful in the selection of articles which in average have a larger impact in the scientific community than non-awarded publications.     

Zur Rolle einer optimierten Verteilung von Sicherheiten im internen Risikomanagement

The experiences from the recent financial crises show that the estimation and control of credit risks in banks are of significant managerial and economic importance. In this setting, the internal risk management as well as corresponding legal policies put an emphasis primarily on the prognosis of future credit defaults, whereas the role and impact of collaterals only play a minor role. Against this background the paper at hand analyzes the optimized distribution of collaterals within the internal risk management of banks at first. Furthermore, we develop a new flexible allocation algorithm that exceeds the existing approaches concerning the optimization without giving up the rule of a conservative appraisal of credit risk.     

Einfluss von Vorgesetzten, T?tigkeit, Arbeitsbedingungen und variabler Besoldung auf die Motivation von Mitarbeitern im ?ffentlichen Dienst

This paper analyses the effects of four main influence factors on motivation of public personnel. These influence factors are “superior”, “job satisfaction”, “work environment”, and “variable wages”. I analyse the four factors by using a structural equation model with empirical data. My focus lies on the complex interdependencies of influence factors among each other. There is empirical evidence that the influence factor “job satisfaction” plays a decisive role in public service motivation. Moreover, the influence factors “work environment” and “variable wage” have a quite low direct effect on motivation. Surprisingly, the influence factor “superior” has an strong effect on “job satisfaction” and on “variable wages”.     

Globalization debates: bringing in microencounters

Resistance is not only a response to, but also an integral component of neoliberal globalization. Public debates and most scholarly discourse have focused on macroresistance, which signals a new dynamic in globalization, but to the neglect of microresistance. Macroresistance may be best grasped as a political intervention by a coalition of heterogeneous citizens' groups in a globalizing economy, often in the guise of movements, networks and even state policies. Not surprisingly, the least understood type of resistance is the more latent, often undeclared, diffuse and sometimes localized, micro variant. Microresistance is constituted by countless diverse acts and beliefs that send forth streams of doubt and questions concerning the viability and sustainability of neoliberal globalization. Studying microresistance suggests that a large part of the resistance to neoliberal globalization is scattered and differentiated, private and intimate, personal as well as public, as evidenced in Japan after the bubble burst. In so far as this resistance is local yet parallel to responses in different countries and regions, the emergent pattern is potentially freighted with macrosignificance. The analytical challenge is to come to grips with the interplay of micro- and macroresistances. Fundamentally, a priority in research is to uncover the whole series of mediations among resistances, which are central to the historical transformation known as globalization.     

The Relative Contribution of Health Status and Quality of Life Domains in Subjective Health in Old Age

To analyze the influence of different health status dimensions and quality of life (QoL) domains on older adults’ subjective health, and to assess the role that residential satisfaction plays in these relationships. A QoL survey was conducted on a representative sample of the community-dwelling older adult population in Madrid province (Spain). Logistic regression models were applied to studying: the health status dimensions associated with satisfaction with health; the relationship between satisfaction with health and other QoL domains; and, the influence of these domains on satisfaction with life. Sociodemographic and residential characteristics were included in all the models. The determinants of satisfaction with health in the first model were: mobility, usual activities, morbidity, and satisfaction with neighborhood. QoL domains associated with health were: leisure activities, neighborhood, and finances. Satisfaction with life was explained by these three domains, along with age, family and health. In sum, leisure, neighborhood, and finances showed a positive effect on satisfaction with health and with life.     

Die Geld-zur��ck-Garantie �C Mehr als nur ein Qualit?tsindikator?

Money-back guarantees have become an increasingly popular tool for marketing managers??mainly because they are regarded as an effective means to signal product quality. However, from an academic perspective there is sparse empirical evidence on whether such a signaling effect really exists and, most importantly, whether it influences consumer decision making. Hence, the objective of the paper is to empirically analyze the consequences of money-back guarantees on consumer buying behavior in a holistic theoretical framework accounting for both cognitive and affective consumer responses. Our results reveal that the existence of the rather cognitively driven signaling effect of a money-back guarantee is contingent on several factors: Besides the type of the product (search versus experience good), it particularly depends on consumer knowledge as well as on whether a money-back guarantee is offered for a strong or for a rather weak brand. In addition, we show that a money-back guarantee also induces affective consumer responses which additionally contribute to consumer buying behavior. These responses are mainly due to the guarantee??s insurance function reducing consumer uncertainty about product features.

Pareto efficiency in multiple referendum

We consider situations of multiple referendum: finitely many yes-or-no issues have to be socially assessed from a set of approval ballots, where voters approve as many issues as they want. Each approval ballot is extended to a complete preorder over the set of outcomes by means of a preference extension. We characterize, under a mild richness condition, the largest domain of top-consistent and separable preference extensions for which issue-wise majority voting is Pareto efficient, i.e., always yields out a Pareto-optimal outcome. Top-consistency means that voters’ ballots are their unique most preferred outcome. It appears that the size of this domain becomes negligible relative to the size of the full domain as the number of issues increases.
