For the insurance industry the moral hazard poses an incalculable risk. Changes in the behaviour of the insuree can lead to higher claims settlements and thus to higher premiums for the insured collective. Asymmetrically allocated information gives the insured individual the possibility to profit from the idea of common protection in a way that impairs insurer and the collective on the whole. Based on the homo oeconomicus model, economic concepts, first and foremost the agency theory of new institutional economics have made attempts to provide solutions for this management problem. However, behavioural economic experiments have demonstrated that the homo oeconomicus model does not fully succeed in describing the realities. As a result, the solutions proposed in these economic concepts have to be rated inadequate.The moral hazard is inherent in the conflicting realm of cooperation and defection, behaviour patterns that have evolved during the history of development of human behaviour. Ultimate behaviour analyses of these patterns do offer the opportunity to understand why humans behave in specific ways based on man's evolutionary origins and sources. Consequently, ultimate behaviour analyses could provide a solid foundation for the development of a framework giving insurers the possibility to exert influence on the insuree's behaviour and thus to assist in successfully impacting the moral hazard.  相似文献

In this paper we analyse the source and magnitude of marketing gains from selling structured debt securities at yields that reflect only their credit ratings, or specifically at yields on equivalently rated corporate bonds. We distinguish between credit ratings that are based on probabilities of default and ratings that are based on expected default losses. We show that subdividing a bond issued against given collateral into subordinated tranches can yield significant profits under the hypothesised pricing system. Increasing the systematic risk or reducing the total risk of the bond collateral increases the profits further. The marketing gain is generally increasing in the number of tranches and decreasing in the rating of the lowest rated tranche.  相似文献

The study aims at verifying whether the firm size and debt maturity affect the relationship between capital structure and its main determinants. Using panel data models, the impact of the primary factors on leverage is compared across three size groups of firms and for different measures of debt in order to identify the size effect and the debt maturity effect in these relationships. The study covers 11 EU countries during the period 2000–2013. Findings provide evidence that financing choices of small firms provide more support for the pecking-order theory, whereas medium and large-sized firms tend to follow the trade-off predictions on leverage. It also appears that the trade-off theory is more applicable for short-term debt, while pecking order – for long-term debt.  相似文献

<正>一、简介20世纪70年代能源危机之后,人们开始更加关注所谓"能源安全"的概念以防能源供应的中断。从那以后,廉价石油的时代结束了,人们必须考虑到多种变化因素以确保长期的石油供应。从需求角度讲,能源需求(尤其是石油)将不断增长。从供应商角度讲,石油资源仅贮于很少一部分国家(尤其是中东国家)会引发使用"石油武器"的潜在威胁。而且,高额的石油价格也使得非传统石油能源在能源市场占有一席之地。  相似文献

A Critical Review of Centrality Measures in Social Networks   总被引:2,自引:1,他引:1  
Social networks are currently gaining increasing impact in the light of the ongoing growth of web-based services like facebook.com. One major challenge for the economically successful implementation of selected management activities such as viral marketing is the identification of key persons with an outstanding structural position within the network. For this purpose, social network analysis provides a lot of measures for quantifying a member’s interconnectedness within social networks. In this context, our paper shows the state of the art with regard to centrality measures for social networks. Due to strongly differing results with respect to the quality of different centrality measures, this paper also aims at illustrating the tremendous importance of a reflected utilization of existing centrality measures. For this purpose, the paper analyzes five centrality measures commonly discussed in literature on the basis of three simple requirements for the behavior of centrality measures.  相似文献

Onlinebasierte Ideenwettbewerbe mit Web 2.0-Funktionalit?ten bieten neue innovative M?glichkeiten im Online Marketing. Sie tragen dazu bei, die Bekanntheit und positive Wahrnehmung einer Marke in der ?ffentlichkeit zu st?rken. Konsumenten setzen sich intensiver mit einer Marke auseinander, was schlie?lich zu einer st?rkeren Identifikation mit der Marke und Bindung führt. Auch Swarovski, dem Kristall-Weltmarktführer, gelang durch diese Einbindung von Konsumenten der Erfolg.  相似文献

This paper explains how strategic planning is able to deliver strategic integration within organizations. While communication and participation within planning processes are perceived to have an integrative effect, we argue that these effects are unlikely to arise simply from bringing people together. Rather, we suggest that, given the varying interests of actors in different business units, integration will only arise from active negotiations and compromises between these actors. The paper is based upon a case of strategic planning in a multinational that was attempting to develop greater strategic integration across Europe. Drawing upon an activity theory framework, we examine how a common strategy emerges over time through modifications to the planning process and to different actors' roles within it. The findings are used to develop a process model that shows how different business unit characteristics of planning experience and relative power shape different experiences of communication and participation activities and different processes for achieving integration. The paper concludes with a discussion of how this process model contributes to the literature on strategic planning, political processes of strategy-making, and strategy-as-practice.  相似文献

Today, HR scholars widely acknowledge that realising HRM requires the involvement of all managers and that the personal motivation of line managers plays an important role in their successful involvement. Yet, previous research has neglected to study how line managers rate the importance of particular HR duties and how the importance assigned to HR duties varies across managers. Based on a survey of 1,500 Danish managers, we find that ‘motivating others’ is considered the most important HR duty whereas ‘team building’, ‘handling conflicts’ and ‘coaching’ are considered the least important HR duties. Female top managers in the public sector exhibit the greatest interest in HR whereas men at lower managerial levels in the private sector give lowest priority to HR work. We conclude with possible explanations for the observed differences in a Danish context and beyond and provide suggestions for facilitating managerial involvement in HRM. In doing so we are well aware that the Scandinavian model of HRM in general and the Danish implementation in particular may represent a unique frame for the results.  相似文献

This case study utilizes a value of information decision framework to provide mine managers guidance regarding the purchase of ore grade scanners. LKAB's Kiruna mine produces three types of iron ore to meet long-term contractual agreements on a monthly basis. There is a priori uncertainty regarding the ore type in any given mineable section of the orebody. In addition, there is extracted ore type uncertainty that is introduced by the mining process. These uncertainties are better understood by obtaining more precise (real-time) information. In addition, a better understanding of the uncertainties can improve the quality of operational decisions and increase the overall profitability of the mine. This case study provides a framework for measuring the economic impact of information purchases in a mining context and discusses the implications of those findings.  相似文献
