This paper examines the evolution of the pharmaceutical industry. After a brief discussion of the main stylised facts about the industry, we present a history-friendly model that aims at capturing the underlining mechanisms and the logic that guides the evolution of this industry. Simulation...

This paper examines how the nature of the technological regime governing innovative activities and the structure of demand interact in determining market structure, with specific reference to the pharmaceutical industry. The key question concerns the observation that—despite high degrees of...

The analysis of innovation, industrial dynamics and the evolution of industries has witnessed major progress in several areas. The paper discusses the progress made in the industrial dynamics tradition and in the more recent stream of studies centred on the evolution of sectoral systems. It...

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...

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 analysis of innovation and the evolution of industries evolution has witnessed major progress in several areas. Contributions at the empirical, appreciative, econometric and modelling levels have greater advanced our understanding of innovation, industrial dynamics and the different...
