By using extremely detailed data on European chemical patents, this work focuses on the micro levelof research networks. It examines the networks of inventors for the development of innovations. Itstudies whether the firm or the geographical proximity among inventors influences the probability...

This paper evaluates some of the technological and economic factors that underlie the choice between in-house R&D, R&D alliances and outsourcing. We recount the reasons for the growth in non-internal activities, and explain why these are not as prevalent for R&D as other value-adding activities,...

In this paper a model for the formation of strategic alliances is studied. Innovation results from the recombination of knowledge held by the partners to the collaboration, and from the history of their collaboration. Innovation brings partners closer together, while at the same time the...

This paper develops a framework for testing discrete complementarities in innovation policy using European data on obstacles to innovation. We propose a discrete test of supermodularity in innovation policy leading to a number of inequality constraints. We apply our test to two types of...

This case study questions how Flanders Language Valley developed as a cluster of localized technological change. Through licensing the attracted small, mostly foreign firms use the research lab of L&H Speech Products as a common source of codified knowledge and with their fast entrepreneurial...

This paper examines the relevance of both an efficiency-based network strategy and a learning-based network strategy in the context of inter-firm partnering. The effect of these different forms of network behaviour on company performance is analysed for companies in the international computer...

The paper examines the dynamics of the amateur camera market – a mature industry - in the period 1955-1974. The case study raises a number of important issues for innovation management in mature industries characterised by heterogeneous preferences and heterogeneous product designs. First, it...

Some industries are characterised by networks of small and specialized firms with porous boundaries, while in some other industries large diversified hierarchies with concrete boundaries are a more dominant form of organization. Some other industries are combinations of these. In this paper, a...

This paper models the formation of R&D networks in an oligopolistic industry. In particular, it focuses on the coevolutionary process involving firms’ technological capabilities, market structure and the network of interfirm technological agreements.The main result of the paper is that the R&D...

Theories and models on product life cycles explain and depict the evolution of an industry''s structural and dynamic properties over its lifetime. Hence, empirically observed intersectoral differences may stem from different evolutionary stages that industries occupy. The aim of this paper is to...
