This paper analyzes how scale free resources, which can be acquired by multiple firms simultaneously and deployed against one another in product market competition, will be priced in strategic factor markets, and what the consequences are for the acquiring firms' performance. Based on a game‐theoretic model, it shows how the impact of strategic factor markets on economic profits is influenced by product market rivalry, preexisting competitive (dis)advantages, and the interaction of acquired resources with those preexisting asymmetries. New insights include the result that resource suppliers will aim at (and largely succeed in) setting resource prices so that the acquiring firms earn negative strategic factor market profits—sacrificing some of their preexisting market power rents—by acquiring resources that they know to be overpriced.

This article employs an augmented version of the UECCC GARCH specification proposed in Conrad and Karanasos (2010) which allows for lagged in‐mean effects, level effects as well as asymmetries in the conditional variances. In this unified framework, we examine the twelve potential intertemporal relationships among inflation, growth and their respective uncertainties using US data. We find that high inflation is detrimental to output growth both directly and indirectly via the nominal uncertainty. Output growth boosts inflation but mainly indirectly through a reduction in real uncertainty. Our findings highlight how macroeconomic performance affects nominal and real uncertainty in many ways and that the bidirectional relation between inflation and growth works to a large extent indirectly via the uncertainty channel.  相似文献

This paper analyzes exit strategies of buyout funds in portfolio companies following initial public offerings (IPOs). We use a data set of 222 buyout‐backed IPOs in the United States from 1999 to 2008, including hand‐collected data about each exit process, to draw a detailed roadmap of buyout investors’ divestment processes. Using this data, we document the timing and aggressiveness of the exit strategies, and analyze to which degree a multitude of possible determinants influence the choice of a given exit strategy. Our results indicate that buyout funds remain invested in their portfolio companies for a substantial period of time after the IPO, and that the choice of a given exit strategy depends not only upon the characteristics of each respective portfolio company, but also on the financial success of the deal from the perspective of the buyout investor.  相似文献

This paper provides a comparison of three voting rules, the Borda rule, the Copeland rule and the maximin rule. Our analysis based on the rankings derived from those voting rules will shed new light on existing comparisons based on “closeness” between the three voting rules under investigation. In particular it will be shown that both, the rankings derived from the Borda rule and the maximin rule and the rankings derived from the Copeland rule and the maximin rule, will be exactly the opposite for certain preference profiles.  相似文献

The dynamic growth of biotechnology in Germany in recent years has an obviously spatial pattern. Some regions show a substantial potential for start-ups and young firms of this new industry whereas others lag behind. The paper is discussing this unequal spatial development elaborating perspectives which derive from recent debates about regional innovation systems. The biotech regions Munich and Rhineland, both winner regions of the BioRegio Competition are described and compared with the situation in Hamburg where biotechnology is much less important. We analyze the degree and relevance of locally integrated input-output relations of innovation systems based on typologies of the wide range of firms within the biotechnological value chain and the forms of co-operation. Moreover, a qualitative estimate is given with respect to the significance of untraded relationships and regional knowledge spillovers. Factors favoring local integration are compared with those favoring input-output systems on a transatlantic scale. The paper discusses the question whether the biotech industries in the regions of Munich, Rhineland and Hamburg represent identifiable regional systems of innovation.Our findings show that the spatial concentration does not necessarily imply a close network of input-output relations within a cluster. Knowledge and technology transfer often happens on a international, mostly on the North Atlantic scale. The exchange of tacit knowledge, however, is facilitated by spatial proximity. This underlines the importance of untraded relations and "relational assets" in a region. Political and institutional support for building a "business community" can reduce barriers to launch risky commercialization processes.  相似文献

A Cross-Cultural Examination of the Endorsement of Ethical Leadership   总被引:2,自引:0,他引:2  
The western-based leadership and ethics literatures were reviewed to identify the key characteristics that conceptually define what it means to be an ethical leader. Data from the Global Leadership and Organizational Effectiveness (GLOBE) project were then used to analyze the degree to which four aspects of ethical leadership – Character/Integrity, Altruism, Collective Motivation, and Encouragement – were endorsed as important for effective leadership across cultures. First, using multi-group confirmatory factor analyses measurement equivalence of the ethical leadership scales was found, which provides indication that the four dimensions have similar meaning across cultures. Then, using analysis of variance (ANOVA) tests each of the four dimensions were found to be universally endorsed as important for effective leadership. However, cultures also varied significantly in the degree of endorsement for each dimension. In the increasingly global business environment, these findings have implications for organizations implementing ethics programs across cultures and preparing leaders for expatriate assignments. Christian J. Resick is Assistant Professor of Industrial and Organizational Psychology at Florida International University. His research is aimed at understanding how people interact with and influence various aspects of their work environments, including cultures, climates, leaders, and teammates along with the implications for various aspects of organizational behavior. A particular focus of Christian’s work examines ethical leadership and the critical linkages between leadership and organizational ethics. He received his Ph.D. from Wayne State University. Paul J. Hanges is a professor in the Department of Psychology at the University of Maryland and the head of the Industrial/Organizational Psychology program in the department. He is an affiliate of the Cognitive Psychology program and the R. H. Smith School of Business.

This paper examines the critical role that organizational leaders play in establishing a values based climate. We discuss seven mechanisms by which leaders convey the importance of ethical values to members, and establish the expectations regarding ethical conduct that become engrained in the organizations climate. We also suggest that leaders at different organizational levels rely on different mechanisms to transmit values and expectations. These mechanisms then influence members practices and expectations, further increase the salience of ethical values and result in the shared perceptions that form the organizations climate. The paper is organized in three parts. Part onebegins with a brief discussion of climates regarding ethics and the critical role of values. Part two provides discussion on the mechanisms by which leaders and members transmit values and create climates related to ethics. Part three provides a discussion of these concepts with implications for theory, research, and practice.  相似文献
