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...

This paper is a first attempt at modelling the long term dynamics of market structure and innovation in the pharmaceutical industry in a history-friendly way. The model examines the relationships between the nature of the search space, demand, the patterns of competition and industry evolution...

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...

The history of a number of industries is marked by a succession of eras, associated with different dominant technologies. Within any era, industry concentration tends to grow. Particular eras are broken by the introduction of a new technology which, while initially inferior to the established...
