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...

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 towards the full inclusion of a group of variables greatly studied in the current literature on innovation and industrial economics -such as knowledge links and the structure of competition and collaboration in a sector -into the determinants of the international...

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...

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 analyses the relative effects of national and international, intra-sectoral and intersectoral spillovers on innovative activity in six large, industrialized countries (France, Germany, Italy, Japan, UK and US) over the period 1981-1995. We use patent applications at the European...

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 main goal of this paper is to assess the impact of product innovation on the economic performance of firms operating in medium and high-tech industries in general and of SMEs in particular. Using information from a large and unique dataset on Italian firms we estimate, by means of propensity...
