This paper presents and discusses the methodological rationale, the basic structure and some first results of a new approach to the analysis of processes of industry evolution: "history-friendly" models, concerning the history of the computer industry. The specific purpose of this paper is to...

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 of...

In this paper we examine the effects that user-producer interactions have on innovation and the dynamics of market structure of two vertically related industries under alternative contractual regimes. The existence of advantages stemming from users-producers relationships introduces a dynamic...

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 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 proposes that the specific pattern of innovative activities in an industry can be explained as the outcome of different technological (learning) regimes. A technological regime is defined by the particular combination of technological opportunities, appropriability of innovations,...

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...
