We analyse the effect of a large scale infrastructure investment, namely the construction of the Oresund bridge, on the local and supra-regional economy. We employ the synthetic control method to construct counterfactual regions that mimic the trajectory of Malmo and Southern Sweden without treatment. Our results point to a positive effect. However, placebo tests in space and time only reveal statistical significance at a larger regional level. The results suggest that spillover effects are eminent. 相似文献

Bio-economic modelling has become a useful tool for anticipating the outcomes of policies and technologies before their implementation. Advances in mathematical programming have made it possible to build more comprehensive models. In an overview of recent studies about bio-economic models applied to land-use problems in agriculture and forestry, we evaluated how aspects such as uncertainty, multiple objective functions, system dynamics and time have been incorporated into models. We found that single objective models were more frequently applied at the farm level, while multiple objective modelling has been applied to meet concerns at the landscape level. Among the objectives, social aspects are seldom represented in all models, when being compared to economic and environmental aspects. The integration of uncertainty is occasionally a topic, while stochastic approaches are more frequently applied than non-stochastic robust methods. Most multiple-objective models do not integrate uncertainty or sequential decision making. Static approaches continue to be more recurrent than truly dynamic models. Even though integrating multiple aspects may enhance our understanding of a system; it involves a tradeoff between complexity and robustness of the results obtained. Land-use models have to address this balance between complexity and robustness in order to evolve towards robust multiple-objective spatial optimization as a prerequisite to achieve sustainability goals. 相似文献

This paper focuses on the process of Computer Aided Design (CAD) diffusion into a group engaged in the development of innovative products. Adopting an ethnographic approach, we build a grounded theory for interpreting CAD usage in terms of the interplay between variables such as management orientation, training, actors' specialisation and deskilling, availability of shared archives, technological discontinuities between organisational areas. 相似文献

Zusammenfassung Aus bisherigen Studien lassen sich kaum Handlungsempfehlungen ableiten, welche Positionierung eines
Zulieferunternehmens sich besonders vorteilhaft auf das Vertrauen eines Kunden auswirkt. Im vorliegenden
Beitrag werden die Wirkungen von vier Positionierungsstrategien, die Zulieferunternehmen zur Verfügung
stehen, auf das Vertrauen ihrer Abnehmer aus der Automobilindustrie untersucht. Diese Strategien bestehen
in der Anpassung an Kundenprozesse, in Serviceorientierung, in Flexibilit?t und in der Verwendung von
Kompetenzsignalen gegenüber dem Markt. Wir zeigen, dass die Anpassung an Kundenprozesse auf Grund
der hohen Spezifit?t der damit verbundenen Investitionen die st?rkste positive Wirkung auf das
Vertrauen des Kunden aufweist und dass Kompetenzsignale gegenüber dem Markt kein geeignetes Instrument
zur F?rderung des Kundenvertrauens sind, wenn das Zulieferunternehmen für den Abnehmer eine hohe
Bedeutung besitzt.
The effects of a supplier’s positioning strategy on buyers’ trust
Summary Many studies have identified measures that are able to enhance partners’ trust in business-to-business relationships. However, it is not known which measures are more effective than others or under which conditions certain measures might be helpful or not. In the present study the effects of four possible positioning strategies on buyer’s trust are examined. The positioning strategies considered here are the supplier’s adaptations regarding its customer’s processes, its service orientation, its flexibility, and market-signals stressing the supplier’s competence. We found that, due to the high specificity of the required investments, adaptations of the supplier’s processes are the strongest instrument to enhance buyers’ trust relative to the other three strategies. We could also show that investments in market signals stressing the supplier’s competence are not effective if the supplier is of high importance to the customer.相似文献

This article explores the contradiction between the articulated investment policies, screening criteria or ethical charters of socially responsible investment funds and their actions demonstrated by their portfolio selection practice. The paper provides a background to socially responsible investment and Australia's contribution to greenhouse gas emissions. A discussion of renewable energy options lays the foundation for our main assertion: that this set of possible alternatives provides some new and more environmentally robust options that will better complement the underlying philosophy of funds in the socially responsible investment sector. 相似文献

The purpose of this paper is to study how organizational rejuvenation is used to increase and support knowledge exploitation
in multinational enterprises. Using case-study data to explore the theoretical arguments, interesting findings emerge. The
main finding is that entrepreneurial activities in IT industry enable organizational rejuvenation with repercussions beyond
the focal function. Other findings relate to how corporate entrepreneurship activities provide possibilities for continuous
knowledge exploitation within the MNE and how entrepreneurial groups inside MNEs form the foundation from which the organizational
rejuvenation originates. Finally, the form of organizational rejuvenation studied embraced both structural and behavioral
changes.
