针对消费者对转换成本和价格属性具有显著性偏好的实际情况,基于显著性理论对垄断双边平台企业的转换成本和定价策略问题进行了研究。研究发现:1)在显著性偏好非对称型市场上,对价格敏感的一方收取的价格最低,对高转换成本的一方收取的价格最高,而在显著性偏好对称型市场上,平台的最优价格位于非对称型市场之间,但是对价格敏感型市场收取的价格低于转换成本敏感型市场的价格。2)在高转换成本的市场,平台利润最低;低转换成本市场平台利润最高,而混合型情况的最优利润位于这两者之间。该研究结论说明平台企业应该采取措施来降低用户加入平台的转换成本,从而增加利润,这与现实的案例研究结论相吻合。  相似文献

Compared to the remarkable progress in risk analysis of normal accidents, the risk analysis of major accidents has not been so well‐established, partly due to the complexity of such accidents and partly due to low probabilities involved. The issue of low probabilities normally arises from the scarcity of major accidents’ relevant data since such accidents are few and far between. In this work, knowing that major accidents are frequently preceded by accident precursors, a novel precursor‐based methodology has been developed for likelihood modeling of major accidents in critical infrastructures based on a unique combination of accident precursor data, information theory, and approximate reasoning. For this purpose, we have introduced an innovative application of information analysis to identify the most informative near accident of a major accident. The observed data of the near accident were then used to establish predictive scenarios to foresee the occurrence of the major accident. We verified the methodology using offshore blowouts in the Gulf of Mexico, and then demonstrated its application to dam breaches in the United Sates.  相似文献

We examine a key modified labeling theory proposition—that a psychiatric label increases vulnerability to competence-based criticism and rejection—within task- and collectively oriented dyads comprised of same-sex individuals with equivalent education. Drawing on empirical work that approximates these conditions, we expect the proposition to hold only among men. We also expect education, operationalized with college class standing, to moderate the effects of gender by reducing men’s and increasing women’s criticism and rejection. But, we also expect the effect of education to weaken when men work with a psychiatric patient. As predicted, men reject suggestions from teammates with a psychiatric history more frequently than they reject suggestions from other teammates, while women’s resistance to influence is unaffected by their teammate’s psychiatric status. Men also rate psychiatric patient teammates as less powerful but no lower in status than other teammates, while women’s teammate assessments are unaffected by their teammate’s psychiatric status. Also as predicted, education reduces men’s resistance to influence when their teammate has no psychiatric history. Education also increases men’s ratings of their teammate’s power, as predicted, but has no effect on women’s resistance to influence or teammate ratings. We discuss the implications of these findings for the modified labeling theory of mental illness and status characteristics theory.  相似文献

Resource Dependency Theory (RDT) and Global Value Chain (GVC) analysis have been deployed in the strategic and international management literatures to address questions of power in dyadic relationships and global production networks, respectively. This paper integrates the two theoretical approaches in order to expand RDT, using insights from Hirschman's exit/voice model to show the options available to some firms but not others. Using the relationship between buyers and contract manufacturers from GVC analysis, we find a correlation between firm size and choice of strategic action in response to contract manufacturers' dependence on buyers. Large firms follow an acquiescence strategy while small manufacturers follow an avoidance strategy, able to use both exit and voice strategies. Enabled by scale or control over information, both of these approaches successfully reduce uncertainty and provide a source of sustained competitive advantage. Using a study of the production chain in consumer plastics manufacturing in China, we show how dependent firms respond to GVC induced pressure. We find that based on the size of the contract manufacturer, the range of strategic responses to power is constrained by the nature of the dependency in global value chains. This opens important insights into the role that structural characteristics of organizations (like size) play in determining strategic freedom.  相似文献

Abstract

In this paper, we introduce a surplus process involving a compound Poisson counting process, which is a generalization of the classical ruin model where the claim-counting process is a homogeneous Poisson process. The incentive is to model batch arrival of claims using a counting process that is based on a compound distribution. This reduces the difficulty of modeling claim amounts and is consistent with industrial data. Recursive formula, some properties and relevant main ruin theory results are provided. Further, we consider applications involving zero-truncated negative binomial and zero-truncated binomial batch arrivals when the claim amounts follow exponential or Erlang distribution.  相似文献

为了探究利益相关者视角下学前教育小学化产生的原因及其对策,以重心下移与深度聚焦为思路,对Z市X区4名家长和2名老师进行访谈,借助扎根理论,建构出学前教育小学化"错位"与"适应"的双重生态。"错位"诠释了学前教育小学化的"为何",具体表现为"主体错位"和"职责错位"的复杂交错。"适应"解释了学前教育小学化的"何为",具体表现为适应主体是"家长、幼儿园和辅导班的三管齐下";适应策略包括"坚决抵抗、无奈妥协、精明调适和无知得意";适应类型是"预防型和善后型、强迫型和引导型、突击型和持久型、长远型和短视型"的相互融合。  相似文献

To further the understanding of how communication executives make tough calls in times of organizational-public conflict, we use a conjoint analysis to identify key drivers for organizational stance decision-making. This is the first-ever conjoint analysis applied to advancing the contingency theory of strategic conflict management by examining the relative importance of key contingency factors as determined by practitioners with varied individual characteristics. This study investigates: 1) the relevant importance of and dynamics between three key contingency factors (i.e., external threats, organizational characteristics, and dominant coalition characteristics); 2) the influence of individual characteristics (e.g., gender, experience, and personal ethics) in stance decision-making process; and 3) how different types of organizational stances (i.e., general stance, action-based accommodation, and qualified-rhetoric-mixed accommodation) are determined by these contingency factors and individual characteristics in different conflict situations. Results generated among our communication executive participants include: individual characteristics (i.e., gender, ethics and social responsibility, whistleblowing tendencies, and over 20 years in the communications field) are influential for their strategic conflict management decision-making. Implications for refining the contingency theory and unearthing complex public relations decision-making processes via novel statistical techniques are discussed.  相似文献

This article examines the limitations of using a single advocacy-accommodation continuum when depicting organizational stance and movement in conflict situations (Cancel et al., 1997). The authors argue that advocacy and accommodation can vary independently in response to a variety of contingent factors. To comprehensively capture the locations and motions that are possible in organization-public conflicts, a two-continuum approach is proposed. Separate assessment of the effects of contingency variables on advocacy and accommodation can be used to accurately locate organizational stance along advocacy and accommodation continua. Strategic alternatives that cannot be depicted using a single continuum (such as favorable alignment of organization advocacy/public accommodation or unilateral change on the part of one party) can be captured if separate continua are employed. By depicting initial stances and desired directions of movement for both the organization and public, the dual-continuum approach can also provide practical guidance to public relations professionals in selecting strategies for achieving preferred outcomes and evaluating their effectiveness.  相似文献
