Rationalisierung und Rationierung im Gesundheitswesen aus ethischer Perspektive

Demographic ageing and technological progress leads to rising health care costs. Under the assumption that the solidarity-based financing of the German Statutory Health Insurance System will reach its limits, the authors discuss how and on which level questions about rationing should be answered. From an ethical point of view, rationing should be based on general and consistent rules at the governance level rather than on case by case decisions by healthcare providers. Moreover, transparency is inevitable to maintain the relationship of trust between physicians and patients and to improve the patient’s wellbeing.     

Parent hostility and spin‐out performance

Prior research has focused on the performance implications of positive or neutral parent‐child relationships, but neglected negative, conflict‐laden relationships. This study explores from an embeddedness perspective whether parent hostility (degree to which an incumbent firm disapproves of the spawning of a spin‐out from within its ranks) affects spin‐out performance and how spin‐outs can effectively react to it. Analyses of 144 technology spin‐outs support our arguments that spin‐outs suffer negative consequences from hostility. These are less severe, however, if the spin‐out pursues effective network development. Copyright © 2013 John Wiley & Sons, Ltd.     

Endogenous product versus process innovation and a firm’s propensity to export

This article provides an empirical analysis of the effects of new product versus process innovations on export propensity at the firm level. Product innovation is a key factor for successful market entry in models of creative destruction and Schumpeterian growth. Process innovation helps securing a firm’s market position given the characteristics of its product supply. Both modes of innovation are expected to raise a firm’s propensity to export. According to new trade theory, we conjecture that product innovation is relatively more important in that regard. We investigate these hypotheses in a rich survey panel data set with information about new innovations of either type. With a set of indicators regarding innovation motives and impediments and continuous variables at the firm and industry level at hand, we may determine the probability of launching new innovations and their impact on export propensity at the firm level through a double treatment approach.     

Will the EU-ETS instigate airline network reconfigurations?

Based on the proposal of the European Commission on including the aviation sector into the European Emission Trading Scheme, a route-based analysis is conducted simulating cost and demand implications for selected airlines. For a scenario of €20/tons CO₂, results indicate that the EU-ETS CO₂-based cost increases for the airlines are between €9 and €27 per route and therefore, as an individual factor, are not high enough to instigate major route reconfigurations among European airlines.     

Performance of bank mergers and acquisitions: a review of the recent empirical evidence

This review provides a comprehensive analysis of the literature on bank mergers and acquisitions with an emphasis on the last decade. The study identifies and analyzes more than 135 publications focusing on this subject. The publications are grouped along their regional focus and the three main empirical methodologies utilized in the literature. The results are documented in detail and their evolution over time is discussed. The key factors influencing the performance of bank mergers and acquisitions, as identified in the relevant literature, are grouped into three categories and evaluated according to their contribution to the success of a merger. This paper concludes with a brief discussion of the influence of managers on the performance of mergers and acquisitions and evidence on regulatory arbitrage through bank mergers and acquisitions.     

Reputation und Unternehmenserfolg

About 30 years ago the first scientific papers were published that address the construct of corporate reputation from the perspective of management science. This article aims at providing a comprehensive review of the state-of-the-art of corporate reputation research. First, we discuss conceptualizations and operationalizations of this intangible asset. Second, we review studies which examine the relationship between corporate reputation and stakeholder behavior respectively firm performance. We find that a superior corporate reputation influences the behavior of stakeholders favorably and thus has a positive impact on the (financial) success of the firm. Finally, we present some hints for future research.     

Optimal investment for executive stockholders with exponential utility

The scope of this paper is to enhance the model for the own-company stockholder (Desmettre et?al. in Math Methods Oper Res 72(3):347?C378, 2010), who can voluntarily performance-link his personal wealth to his management success by acquiring stocks in the own-company whose value he can directly influence via spending work effort. The executive is thereby characterized by a parameter of risk aversion and the two work effectiveness parameters inverse work productivity and disutility stress. We extend the model to a constant absolute risk aversion framework using an exponential utility/disutility setup. A closed-form solution is given for the optimal work effort an executive will apply and we derive the optimal investment strategies of the executive. Furthermore, we determine an up-front fair cash compensation applying an indifference utility rationale. Our study shows to a large extent that the results previously obtained are robust under the choice of the utility/disutility setup.     

Common political culture: Evidence on regional corruption contagion

Although there are indications of common regional corruption characteristics, empirical studies of corruption have assumed that influences on corruption are country-specific. In this paper we report evidence based on a cross-section of 123 economies confirming that, with few specific exceptions, corruption is a regional phenomenon. Institutional change that reduces corruption in one country affects, therefore, neighboring countries.
