In Proceedings of the British Academy of Management Conference 2005 (CD-ROM) 8 p.http://hdl.handle.net/10400.14/5330The technological development along with the fall of most political barriers has made the world a smaller place. Firms, even those that focus their operations in the domestic market, face an increasing competition. These phenomena have introduced an important shift in the way the competitiveness issue must be regarded. In fact, in a growing number of cases it is a matter of being competitive in webs of relationships where the particular position assumed by one firm is likely to affect not only its own performance but also the evolution of other players. The objective of this paper is to shed a new light on competitiveness supported by collaborative arrangements. The authors develop a model of inter-organizational cooperation based on four attributes: interests, resources, activities and trust.engconference object
