Successful outsourcing of military logistics depends much on cooperation and efficiency, and this article provides an in‐depth analysis of challenges this may pose using collaborative competence theory. Using an exploratory approach, this paper is based on a review of the existing literature and on the experience of the Canadian Armed Forces in a foreign theatre. Specifically, the information collected comes from on‐site observation during the UN mission in Bosnia, semistructured interviews, and archives. Our analysis shows that outsourcing military logistics activities in a foreign theatre should be seen as building and managing a “temporary network.” In order to overcome challenges in such a situation, the Armed Forces must specifically act on the adaptability of all individuals in the theatre. The approach should be based on “collaborative competence.” Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd. 相似文献

The aim of this paper is to propose an integrative framework for understanding the determinants of business strategies to reduce greenhouse gas emissions and the impact of these determinants on performance. The proposed structural equation model is based on a survey of 319 Canadian manufacturing firms. The study calls into question the traditionally positive relationship between a firm's environmental commitment and its economic motivations. However, the results also show a win–win relationship between the commitment to reduce greenhouse gas emissions and financial performance. This study contributes to the understanding of the motivations underlying the efforts manufacturers make to tackle climate change and their economic benefits.

The Effect of International Trade on Labor-Demand Elasticities: Intersectoral Matters 总被引:1,自引:0,他引:1
Sébastien Jean 《Review of International Economics》2000,8(3):504-516
This paper studies the impact of trade on the price-elasticity of aggregate labor demand, based on the idea that a variation in the cost of (a given type of) labor has an effect on the sectoral trade specialization of an economy, at the expense of the domestic productions using this factor intensively, even when the trade balance is kept unchanged. As this effect is more important the more open the economy, trade openness induces an increase in the associated labor-demand elasticity, at least if the country has a comparative disadvantage in the industries using intensively the type of labor considered. This argument is illustrated by a simple model, based on an Armington hypothesis, with an empirical assessment for France. 相似文献

Technical networks (transport, telecommunications, energy etc.) possess paradoxical virtues. They produce ‘structuring effects’ on space, obtaining comparative advantages for the places they serve. But they are ubiquitous factors which also enable a homogenization of space. The myths of deterritorialization and dual space are refuted by empirical analyses of the interaction between networks and territories. Networks ‘format’ market areas and political territories. They create matrixes which until now were controlled by the public powers. Linked to current transformations – globalization, deregulation – the present mode of development of the technical macro‐systems brings about a telescoping of geographical scales which is having an adverse effect on the historic compromise between networks and territories. The boundaries of traditional political space have become obsolete and an economic rationale in the form of an extension of the technical networks predominates. In order to rediscover their policy‐making capacity, local authorities must pay more attention to controlling the occupation of public space as well as to the design and organization of the networks’ hubs. They should encourage the emergence of users as players in the regulation of public utilities so that debates on universal service and territorial equality may be activated. Les réseaux techniques (transport, télécommunication, énergie etc.) sont parés de vertus paradoxales. Ils produiraient des ‘effets structurants’ sur l’espace, procurant des avantages comparatifs aux lieux desservis. Mais, facteurs d’ubiquité, ils permettraient aussi une homogénéisation de l’espace. Ces mythes de la déterritorialisation et de la dualisation de l’espace sont réfutés par les analyses empiriques des interactions entre réseaux et territoires. Les réseaux ‘formatent’ des aires de marché et des territoires politiques; ils fabriquent des métriques, dont les pouvoirs publics avaient jusquà présent la maîtrise. Liées aux transformations en cours – globalisation, dérégulation – le mode de développement actuel des macro‐systèmes techniques entraîne un télescopage des échelles géographiques qui met à mal le compromis historique entre réseaux et territoires. Il y a obsolescence des frontières des espaces politiques traditionnels et prédominance de la logique économique dans l’extension des réseaux techniques. Afin de retrouver des capacités d’action, les collectivités locales doivent porter plus d’attention au contrôle de l’occupation de l’espace public ainsi qu’à la conception et à l’organisation des noeuds de réseau. Elles ont aussi à favoriser l’émergence des usagers comme acteurs de la régulation des services en réseau, afin que soient activés les débats sur le service universel et sur l’équité territoriale. 相似文献

The estimation of physical intensity processes in the context of default risk is investigated here. Using data from Moody's Corporate Bond Default Database, a term structure of default probabilities for different rating classes is constructed each year from 1970 to 2001. Two specifications used for modeling the dynamics of the (risk‐neutral) intensity process in the bond‐pricing literature are then examined empirically: the Ornstein–Uhlenbeck and square‐root cases. The results reveal that the Ornstein–Uhlenbeck case is not an adequate modeling alternative with a rejection of this specification in five out of seven credit classes and nonsignificant mean reverting behavior for all credit classes. The square‐root case obtains better results with four credit classes out of seven for which this specification cannot be rejected and significant mean reversion parameters in many cases. © 2008 Wiley Periodicals, Inc.

Food safety and product liability 总被引:1,自引:0,他引:1
This paper focuses on the U.S. product liability system for food poisoning cases and makes six key points. First, current legal incentives to produce safer food are weak, though slightly stronger in outbreak situations and in markets where foodborne illness can be more easily traced to individual firms. Far less than 0.01% of cases are litigated and even fewer are paid compensation. Second, even if potential plaintiffs can overcome the high information and transaction costs necessary to file lawsuits, monetary compensation provides only weak incentives to pursue litigation. Firms paid compensation in 56% of the 294 cases examined in this study and the median compensation was only $2,000 before legal fees. Third, indirect incentives for firms may be important and deserve more research. For example, firms may be influenced by costly settlements and decisions against other firms in the same industry. Fourth, confidential settlements, health insurance, and product liability insurance distort legal incentives to produce safer food. Fifth, the ambiguity about whether microbial contamination is “natural” or an “adulterant” hinders the legal system from effectively dealing with food safety issues. Sixth, a brief comparison of the incentives from U.S. and English legal systems suggests that more research is needed to understand the strengths, weaknesses, and relative impact of each country's legal system on the incentives to produce safer food. 相似文献

This paper studies the symmetric equilibria of a two-buyer, two-seller model of directed search in which sellers commit to information provision. More informed buyers have better differentiated private valuations and extract higher rents from trade. When sellers cannot commit to sale mechanisms, information provision is higher under competition than under monopoly. In contrast, when sellers commit to both information provision and sale mechanisms, I identify simple conditions under which sellers post auctions and provide full information in every equilibrium, ensuring that all equilibrium outcomes are constrained efficient. Sellers capture the efficiency gains from increased information and compete only over non-distortionary rents offered to buyers. 相似文献

The Logical Framework Approach (LFA) has proved to be a valuable tool for project approval, design, and evaluation. However, a few pitfalls make it hard to use within today's project management framework and to integrate with other project management tools. This article proposes an updated version of the LFA to improve its compatibility with today's corporate culture, project management framework, and tools. We propose to call the updated tool the Logical Framework Approach–Millennium (LFA‐M). The LFA‐M is a seven‐step approach leading to the development of the Logframe‐Millennium (LF‐M), a five‐column and four‐line matrix describing major project commitments and providing an overall understanding of the project. It was successfully implemented at the Canadian Space Agency and the Canadian Nuclear Safety Commission. The LFA‐M fits well within today's project management framework and corporate culture and leads easily to other project management tools. 相似文献

This study investigates whether relaxation of firms' financial constraints is an important outcome of the US cross‐listing mechanism. We use the association between investment spending and cash flow to test for the presence and importance of firms' financing constraints. Consistent with the bonding hypothesis, the results suggest that US exchange and private placement cross‐listings significantly alleviate firms' financing constraints. In addition, the financial benefits associated with exchange listings are larger than those associated with private listings, while on the other hand, over‐the‐counter programs do not improve capital allocation. The study also shows that US exchange cross‐listing benefits have not been eroded by the enactment of the Sarbanes‐Oxley (SOX) Act in 2002. Copyright © 2014 ASAC.
