We use an event-study analysis to understand how alliance activity affects firm risk. The risk measure is the implied volatility of a firm’s stock price and the events are alliance announcements to the market. We build on the previous event-studies in the alliance literature that focus on the change in shareholder value by taking the first step in delineating what part of that value arises from the changes in the firm’s risk. The analysis reveals that a number of factors within a firm’s control can be used to manipulate risk exposure in an alliance, including the similarity of the firm’s and the alliance’s core activities, the governance form of the alliance, and the function of the alliance. 相似文献

This paper presents a conceptual model for the creation and operation of supply networks. Existing conceptual research relating to interorganizational relationships and networks is reviewed in terms of its relevance to understanding supply networks; this research is drawn from the fields of strategic management, channel management, industrial marketing and purchasing, organizational behaviour and supply‐chain management. The different perspectives each field has on networks are highlighted. Contributions made by each in assisting to understand supply networks are discussed and synthesized. Findings from an exploratory survey are used to structure the design of a conceptual model for analysing the processes involved in the creation and operation of supply networks. The authors identify nine different types of networking activities and discuss the nature of these activities in the context of supply. Four different types of contextual factors relating to supply networks are identified. The model is tested in eight in‐depth case studies and a validating survey of 58 focal firm networks. It is concluded that it provides a robust structure that enabled complex, cross‐case analysis of multi‐variable, multi‐disciplinary data from interorganization product/service supply networks, but that further testing by other researchers is required. 相似文献

Management concern surrounding the supply of goods and services from business to business, and the related attempts to understand the phenomena observed therein, appears to rest upon a broad range of incompatible perspectives, from political science (often limited to considerations of power) to the logistical (akin to manipulation of a great, benign but dynamic jigsaw puzzle). It appears that all perspectives abrade against the difficulties of exchanging information, knowledge and innovation within the relationships between buying and selling organizations and the apparent chronic systemic inefficiency that transactions often represent in this context. This article addresses these concerns, exploring the concept of transparency and the developments necessary for it to be useful in exchanging sensitive information and tacit knowledge in supply relationships. Our central concern is how the understanding of transparency and its commercial importance may change when it is expressed as a manageable element of the relationship between two organizations rather than as a general property of a broader system (e.g. a supply network, industrial sub-sector, geographical cluster) and what utility this differentiation might hold for managers. The conclusion to the article, and the implication for managers, is that transparency might indeed be created and usefully managed within supply relationships but that it would differ fundamentally in meaning from previously posited concepts, with the same name, in different contexts. 相似文献

The purpose of this paper is to present the theory of the multi-product firm in situations where the revenue function depends not only on the rate of output but also on changes in the rate of output, and, similarly, where the cost function depends on changes in the rate of factor utilization as well as the rate of their utilization. Since the analysis will utilize the calculus of variations, a general introduction to this technique is also presented. The model analyzed assumes perfect foresight and knowledge concerning the revenue, cost, and production functions, and the calculus of variations is used to derive the conditions for an extremum. The first section presents the mathematical model and the model of the firm, and the optimality conditions are discussed in the second section. 相似文献

连坐法是先秦法家严刑重刑的标志,"以吏为师,以法为教"是其文化专制的标志,它们的形成与《周礼》关系密切.《周礼》的乡遂制度为连坐法的形成提供了模式,而担负着国家政令传播职责的吏师制度则是法家"以吏为师,以法为教"文化专制的蓝本. 相似文献

本研究对505名员工及他们的124名直接主管按照4∶1的比例做了配对调查并对调查结果进行多层数据分析,考察工作压力、工作匹配度、工作-家庭冲突对员工积极组织行为的影响,分析了工作-家庭冲突的中介作用以及员工外倾性人格特质的调节作用。结果发现,工作-家庭冲突对员工的积极组织行为产生显著的负向影响;工作-家庭冲突在工作匹配、工作压力与员工积极组织行为的关系中起到中介作用;员工外倾性人格特质对工作-家庭冲突与员工积极组织行为之间的关系有调节作用,即外倾性人格特质能够降低工作-家庭冲突的负面影响,减弱其对员工积极组织行为的不利影响。 相似文献

通过对中国大陆19个省市自治区的1 795名在职员工的问卷调查发现,员工感知到的团队凝聚力能够通过工作-家庭促进的中介效应影响员工在职行为(积极行为与退缩行为);伴随着领导-成员交换关系的密切,团队凝聚力对员工积极行为的影响也更为显著;而在团队凝聚力与退缩行为的关系中,并没有发现领导-成员交换关系的显著调节作用。 相似文献
