This paper proposes a new approach to explain the long-term evolution of a supplier industry. The network of vertical relations between suppliers and buyers is identified as a determinant of the concentration of the supplier industry and of the dynamics of market shares. The vertical structure...

The paper explores the idea that properties at the level of firms coevolve with more aggregate properties at the level of market institutions in the dynamics of industries. We propose that the structure of network of vertical relations limits the effect of increasing returns at the firm level....

This paper addresses the problem of the general validity of models of the industry life cycle, which have been proposed to analyse the long-term evolution of many industries, exhibiting a typical pattern of shakeout. We study a case of non shake-out in the commercial jet aero-engine industry,...

This paper provides a novel contribution for specifying the role of demand for technological competition. The focus is on the analysis of the mechanisms of technological learning and spillovers occurring in different structures of networks of vertically-related industries. The paper offers a...

The paper develops the argument that the long-term structural evolution of an industry depends on the evolution of a vertically-related, downstream industry. We analyse two pairs of vertically-related industries, the jet and turboprop aircraft and engine industries, since the first introduction...

By drawing information from a survey of inventors of 9,017 European patents (PatVal-EU), this paper provides novel and detailed data about the characteristics of the European inventors, the sources of their knowledge, the importance of formal and informal collaborations among researchers and...

This paper studies the geographical breadth of knowledge spillovers. Previous research suggests that knowledge spillovers benefit from geographical proximity in technologically active and rich regions more than elsewhere. An alternative view explains the geographical breadth of knowledge...
