Research Summary: Much of the research on corporate collective action to manage common pool resources is focused on coordinated actions, such as voluntary programs, rather than collaborative actions, such as technology sharing. In this article, we examine inductively the collective actions taken by a consortium of 12 oil sands companies to address three environmental issues of different scale. We identified a set of organizing rules that determined whether the relationship among industry members would be collaborative or competitive, and found that the organizing rules for collaborative collective action were more effective for smaller scale issues (i.e., tailings ponds and water) than the larger scale issue (i.e., greenhouse gas emissions). Our findings contribute to research on the competitive dynamics of collaborating with competitors and on industry self‐regulation. Managerial Summary: Many environmental issues, such as climate change, water quality, and contaminated land, are caused by the overexploitation of commonly shared natural resources. Firms will often overuse resources because their cost of use is less than the benefit that accrues. In Alberta’s oil sands, 12 of the major oil sands operators, all competitors, have agreed to collaborate by sharing technology, which goes against the received wisdom of competition. This multiparty collaboration among competitors, while still relatively rare, is becoming increasingly commonplace. In this article, we outline the rules that allow this collaboration to flourish. Our most important finding is that the rules are shaped by the scale of the issue being managed, not the size of the collaboration.  相似文献

Bycatch of threatened, endangered or protected species by commercial fishers is a universal problem. Technical solutions are often applied that may impose inefficiencies across the fleet, even in periods or areas when the risk of bycatch is low. These may include gear specifically designed to avoid the bycatch which may also reduce the targeted catch, or designation of marine protected areas that exclude fishing from whole areas. In this article, we examine the effectiveness of a variable penalty system that can provide incentives for fishers to redirect their effort away from problem areas. The system is examined using a case study of fishery, which is currently subjected to gear and closure controls to limit bycatch of turtles and seabirds. An alternative incentive-based management policy using a series of differential hook penalties has been proposed as a flexible tool to discourage vessels operating in certain areas. The effects of various hook penalties and closures in key areas on fishing effort in those areas and elsewhere as well as vessel economic performance are assessed using a location choice model. The results suggest that incentive-based approaches may result in lower costs to industry than closures provided some level of residual bycatch is acceptable.  相似文献

Governments and health agencies worldwide are planning for a potential influenza pandemic. Their plans acknowledge the importance of public communication during an outbreak and include related guidelines and strategies. Emerging infectious disease (EID) communication is a new addition to the literature, drawing on health promotion communication, crisis communication and environmental/technological risk communication. This paper adds to the literature, exploring the notion of ‘effective communication during health crises' by reporting on interviews with 22 public health officials, scientists and communications professionals responsible for communicating with the public. When analyzed in the context of the risk communication literature, the interviews reveal several considerations for health risk communicators. First, given the important role that mass media will play in an EID outbreak, there is an urgent need for public health to build partnerships with journalists based on an understanding of the two parties' unique societal roles. Second, seemingly practical communications considerations – such as how certain to be about information before sharing it and whether to engage in two‐way communication with the public – have ethical dimensions that deserve attention. Third, there are unique challenges associated with communicating uncertainty, which would benefit from an exploration of the role of trust in health crisis communication.  相似文献

With group judgments in the context of the Analytic Hierarchy Process (AHP) one would hope for broad consensus among the decision makers. However, in practice this will not always be the case, and significant dispersion may exist among the judgments. Too much dispersion violates the principle of Pareto Optimality at the comparison level and/or matrix level, and if this happens, then the group may be homogenous in some comparisons and heterogeneous in others. The question then arises as to what would be an appropriate aggregation scheme when a consensus cannot be reached and the decision makers are either unwilling or unable to revise their judgments. In particular, the traditional aggregation via the geometric mean has been shown to be inappropriate in such situations. In this paper, we propose a new method for aggregating judgments when the raw geometric mean cannot be used. Our work is motivated by a supply chain problem of managing spare parts in the nuclear power generation sector and can be applied whenever the AHP is used with judgments from multiple decision makers. The method makes use of principal components analysis (PCA) to combine the judgments into one aggregated value for each pairwise comparison. We show that this approach is equivalent to using a weighted geometric mean with the weights obtained from the PCA.  相似文献

Nonprofit organizations (NPOs) operate within marketing systems comprising broader networks of individuals, groups, and/or entities linked through shared participation in economic exchanges. These systems include diverse constituents with varied goals and orientations. Inherently, tensions arise as NPOs, for‐profit firms, and other social actors pursue differing agendas, often competing for finite resources. In this paper, we report the results of an ethnographic study, which examines one community's efforts to alleviate these tensions as they occur in a downtown business district. The area is noted for its economic vitality and diversity, but struggles to accommodate the needs of the homeless population and the social service agencies who maintain a presence there. Relationships between multiple constituencies erode as the business community seeks to displace both the social service agencies and the individuals they serve. The community in this study moved through thematic stages of problem solving associated with contentious social issues. They sought to use a bridging organization by forming a local homeless task force. An apparent breakdown occurred when the task force was unable to articulate integrative values and a vision for the community as a whole. The study illustrates the importance of establishing a set of shared values and vision and emphasizes the importance of the establishment of bridging organizations with power and authority to negotiate and implement changes. It challenges the utilization of sociospatial and relational mechanisms, which are designed to physically shift the homeless from the area.  相似文献
