In Bayesian environments with private information, as described by the types of Harsanyi, how can types of agents be (statistically) disassociated from each other and how are such disassociations reflected in the agents' knowledge structure? Conditions studied are (i) subjective independence (the opponents' types are independent conditional on one's own) and (ii) type disassociation under common knowledge (the agents' types are independent, conditional on some common‐knowledge variable). Subjective independence is motivated by its implications in Bayesian games and in studies of equilibrium concepts. We find that a variable that disassociates types is more informative than any common‐knowledge variable. With three or more agents, conditions (i) and (ii) are equivalent. They also imply that any variable which is common knowledge to two agents is common knowledge to all, and imply the existence of a unique common‐knowledge variable that disassociates types, which is the one defined by Aumann. 相似文献

For nearly two decades, electronic data interchange (EDI) has been widely viewed as a technology pivotal to supply chain management that has also provided benefits to firms on multiple levels. Despite a substantial body of literature, there are a number of conflicting and inconclusive research results in this field. In this study, we synthesize the diverse body of research in EDI by organizing the literature into an initial theoretical framework. Based on a meta‐analysis of results from the empirical literature, we seek to clarify conflicting results from the literature in order to develop a more unified theoretical framework of contextual variables associated with EDI adoption factors and outcomes. From a managerial standpoint, our literature‐based framework offers a set of guidelines for making successful EDI adoption and implementation decisions. 相似文献

The limited capabilities and resources available within many small‐ and medium‐sized enterprises frequently hamper an effective response to environmental pressures, which in turn hurts large buying firms (i.e., customers). Using a case study method with multiple suppliers of two large buying firms, we mapped factors that initiated and improved environmental capabilities in small‐ and medium‐sized enterprises over time. Through several specific mechanisms, buyers' green supply chain management initiated and then enabled the improvement of suppliers' environmental capabilities. Independent of buyers, internal championing of environmental concerns also provided an impetus for small‐ and medium‐sized enterprise suppliers to acquire resources outside the supply chain. Thus, synergistic linkages emerged in supportive buyer‐supplier relationships, resource acquisition, and capability development. When these findings are combined with earlier research on larger suppliers, an integrative framework emerges that provides direction for suppliers, buyers, and public agencies seeking to improve environmental performance. 相似文献

The most commonly employed theories of corporate social performance (CSP) tend to ignore firm‐level processes and structures as sources of competitive advantage. But, by taking a resource‐based view (RBV), and by enhancing a firm's capability to engage in socially responsible activities, it can potentially create its own competitive advantages. We examine four major components of CSP—community relations, the environment, diversity, and employee relations. And we show that the ability of a firm to develop its knowledge and skills—as well as policies and implementation plans and procedures—in each of these areas is a potential resource that may in fact provide competitive advantages and higher organizational performance, bringing benefits to both society and the firm. The community dimension evaluates the firm's performance in relationship to philanthropic giving and community support. The environmental aspect considers such firm stewardship activities as pollution prevention, global warming, and recycling. The diversity component measures CSP considering such factors as board member diversity and a firm's hiring, evaluation, training, and promotion policies concerning women and minorities. The employee relations dimension examines such socially responsible human resource practices as innovative employee involvement programs and profit sharing. Together, these capabilities can provide tangible and intangible resources that can provide the firm with competitive advantages. © 2008 Wiley Periodicals, Inc. 相似文献

The entrepreneurial self‐efficacy of lead founders has been generally considered to be a robust predictor of the performance of their firms. Few studies, however, have considered variables that might moderate this relationship. The current study attempts to fill this gap in the literature by examining two possible moderators of the effects of entrepreneurial self‐efficacy on firm performance: dispositional optimism and environmental dynamism. Results indicate that these factors do indeed moderate the effects of entrepreneurial self‐efficacy; in fact, a three‐way interaction between self‐efficacy, optimism, and environmental dynamism was observed with respect to firm performance. Consistent with predictions, in dynamic environments, the effects of high entrepreneurial self‐efficacy on firm performance were positive when combined with moderate optimism, but negative when combined with high optimism. In stable environments, in contrast, the effects of self‐efficacy were relatively weak, and were not moderated by optimism. Overall, results suggest that high self‐efficacy is not always beneficial for entrepreneurs and may, in fact, exert negative effects under some conditions.

Empirical research on strategic alliances has been limited because previous studies examined alliance outcomes, and the factors associated with them, from a single partner in a manufacturing alliance. Furthermore, many of these studies have been done from a transaction cost perspective and researchers have inferred opportunistic behavior, rather than directly measuring it and observing its actual relationship with alliance performance. Building on previous transaction cost theory and research, this study seeks to address these gaps by analyzing factors associated with both opportunistic behavior and alliance performance within a major service sector, namely the US healthcare industry. After controlling for asset specificity and alliance age, we found that partner trustworthiness and contractual safeguards were negatively related to opportunistic behavior. Furthermore, opportunistic behavior was negatively related to alliance performance, as hypothesized. Interestingly, mutual equity investments were found to be unrelated to opportunistic behavior, counter to transaction‐cost logic. These findings refine and extend the transaction‐cost economics perspective regarding our understanding of strategic alliance behavior and outcomes, and offer executives in service‐based industries some practical ideas for assuring favorable strategic alliance outcomes. 相似文献

Though built with increasingly precise microfoundations, modern optimizing sticky price models have displayed a chronic inability to generate large and persistent real responses to monetary shocks, as recently stressed by Chari, Kehoe, and McGrattan (2000). We trace this lack of persistence to a standard view of the cyclical behavior of real marginal cost built into current sticky price macro models. Using a fully articulated general equilibrium model, we develop an alternative perspective on real marginal cost that leads to substantial persistence. Based on an important role for materials input, variable capacity utilization, and labor adjustment on the extensive margin, this alternative view also makes the sticky price model display volatility and comovement of factor inputs and factor prices more closely in line with conventional wisdom about business cycles and various empirical studies of the dynamic effects of monetary shocks.

This article provides a brief critical examination of a 2002 report jointly issued by the World Health Organization and the World Trade Organization on WTO law and public health. The author argues that the report is in many respects misleading as to the content of WTO law, as interpreted by the Appellate Body of the WTO, its final court. In particular, the WHO/WTO report systematically understates or underestimates the margins of regulatory autonomy that WTO member states have to make regulations that protect public health. 相似文献

Food safety objectives (FSOs) are established in order to minimize the risk of foodborne illnesses to consumers, but these have not yet been incorporated into regulatory policy. An FSO states the maximum frequency and/or concentration of a microbiological hazard in a food at the time of consumption that provides an acceptable level of protection to the public and leads to a performance criterion for industry. However, in order to be implemented as a regulation, this criterion has to be achievable by the affected industry. In order to determine an FSO, the steps to produce and store that food need to be known, especially where they have an impact on contamination, growth, and destruction. This article uses existing models for growth of Listeria monocytogenes in conjunction with calculations of FSOs to approximate the outcome of more than one introduction of the foodborne organism throughout the food-processing path from the farm to the consumer. Most models for the growth and reduction of foodborne illnesses are logarithmic in nature, which fits the nature of the growth of microorganisms, spanning many orders of magnitude. However, these logarithmic models are normally limited to a single introduction step and a single reduction step. The model presented as part of this research addresses more than one introduction of food contamination, each of which can be separated by a substantial amount of time. The advantage of treating the problem this way is the accommodation of multiple introductions of foodborne pathogens over a range of time durations and conditions. 相似文献
