We argue that the distinction between tacit and codified knowledge is indeed very important, but it constitutes only a part of the categorization of the dimensions of knowledge relevant for understanding innovative activities and firms' and industrial evolution. In particular, we emphasize the...

In this article, 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 outstanding collection provides a fitting tribute to the diversity and depth of Paul David’s contributions. The papers included range from simulation models of the evolution of market structure in the presence of innovation, through historical investigations of knowledge networks and...

<i> Modelli history-friendly dell'evoluzione delle industrie: il caso dell'industria del computer </i> (di Franco Malerba, Luigi Orsenigo) - ABSTRACT: In this paper, we review and discuss the main features of a new generation of evolutionary models: "history-friendly" models. They aim to capture, in a...

Using patent data for four countries (Germany, France, United Kingdom, and Italy) for the period 1968-86, the authors find that the patterns of innovative activities differ systematically across technological classes, while remarkable similarities emerge across countries in the patterns of...

This paper focuses on the relationships between observed patterns of innovative activities within a sector and the related context and underlying microeconomic processes that might account for them. It claims that there are some invariant features (with respect to relative prices and incentives...

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...
