Recently, a wave of corporate acquisitions has swept across Europe, prompted by liberalisation and unification in the European Union. The authors ask the question: Has this made the traditional preference by European firms for alliances and co-operative strategies obsolete? Bearing in mind that, in global terms, alliances are popular, another question is: Should European firms use their experiences in alliances to develop new alliance strategies as an alternative to joining the trend to acquisitions?After a review of the European model of alliances, the authors discuss the pros and cons and rationale for horizontal acquisitions and scale alliances, and argue in favour of more aggressive complementary alliances combined with mergers and acquisitions to expand in Europe as well as globally.

We derive the mean and variance of the random discounted sum when Nis uncertain, as are the Xn's. This quantity arises in applications involving random cash-flows over an uncertain number of years. One such application is R&D projects, where both the magnitude and duration of cash-flows are uncertain at the time of investment decision. Previous models have assumed cash-flow duration to be certain. We relax this assumption. We then specialize these results to geometric, mixed-geometric and Poisson distributions of the cash-flow duration.

Mots clés : Core Competencies, R&D, Strategic Management, High-tech

Constantly focused on the role of competencies and resources, firms' strategic management teams are becoming increasingly interested in discovering an effective way of managing the competencies that they possess. In high-tech sectors, these competencies have a direct impact on the firm's future competitive positioning. In other sectors, technological competencies will determine the renewal of product lines. This article examines how firms manage their proprietary research and development programmes and how they succeed in establishing a co-operative relationship with their environment. Our background research includes forty interviews conducted in both the US and Europe

This article discusses the originality of European EUREKA consortia. Formed at the initiative of member firms, these consortia generally adopt a decentralised structure. Their main purpose is to conduct applied research, with the ultimate goal of exploiting its commercial opportunities. The consortia strive to ensure collaboration among firms in different countries, and at times, from different industries. Examining the management of R&D consortia, this article focuses primarily on the creation of new knowledge and competencies and on the benefits that member firms can reap from collaboration. Based on 20 interviews with project managers, the article brings to light two main observations: (1) the leader's positioning is a determining factor, and (2) a perfect balance between the firm's technological development and the consortium's strategic orientation facilitates the acquisition of competencies
