Technical change can affect existing products very rapidly and at an uneven pace depending on the type and on the age of an industry. In young and fast growing industries, the process of technological change usually entails a series of improvements in existing products that affect their...

In this paper we present a history-friendly model of the changing vertical scope of computer firms during the evolution of the computer and semiconductor industries. The model is “history friendly”, in that it attempts at replicating some basic, stylized qualitative features of the evolution...

The rate of technical change that is characterising both the telecommunications and the computer industry has been a major driver of the evolution of a close and stable system into an open and dynamic one. The introduction of a cluster of new technologies has originated significant changes...

In this paper we present a model of the long term dynamics of market structure and innovation in the pharmaceutical industry in a history friendly way. Our results show a strong increase in concentration in each therapeutic area, but a rather low level of concentration in the overall market....

In this paper, we explore the effects of alternative policies, ranging from antitrust to public procurement, open standards, information diffusion and basic research support on the dynamics of two vertically related industries in changing and uncertain technological and market environments. The...

This paper examines whether location in strong industrial clusters translates into a higher probability of innovating. A firm-level analysis of the UK and Italy is performed. Innovative activities of firms (European patent data for 1988-98) are related to regional employment, other...

This paper focuses on niche entry patterns in the LAN equipment industry in the 1990s. We analyze an original data-set of LAN equipment consisting of more than 1,000 hubs and switches marketed between 1990 and 1999. Modularity emerged as a design strategy that supported incumbent firms’...

The rise of Fast Ethernet as the dominant standard for high speed connection in the Local Area Network industry is chosen to analyse the relevance of increasing returns and network externalities in determining the speed of standard diffusion. Although it was not the first standard to emerge,...

We investigate the relationship between product innovation and firm survival for a sample of 121 firms in a high-tech industry. We find that location near the technological frontier is an important determinant of fim survival. Firms located near the frontier are also more likely to be acquired...

This paper investigates the position of China in the international fragmentation of production in the ICT industry, the most dynamic and globally dispersed sector in the world economy. The evidence shows that during the 1990s China dramatically increased its market shares in ICT products and now...
