This paper investigates the relationship between the creation of new firms and the properties of the local knowledge bases, like coherence, cognitive distance and variety. By combining the literature on the knowledge spillovers of entrepreneurship and that on the recombinant knowledge approach,...

The paper analyzes the effects of the properties of firms' knowledge base on the survival likelihood of firms. Drawing upon the analysis of the patterns of co-occurrence of technological classes in patent applications, we derive the coherence, variety and cognitive distance indexes, accounting...

The paper investigates the patterns of persistence of innovation and of the properties of firms' knowledge base (KB) across a sample of Italian firms in the period 1998-2006. The analysis draws upon a theoretical representation of knowledge as a collective good, stemming from the recombination...

This paper applies the methodological tools typical of social network analysis (SNA) within an evolutionary framework, to investigate the knowledge base dynamics of the biotechnology sector. Knowledge is here considered a collective good represented as a co-relational and a...

This paper analyses the co-evolutionary patterns of structural change in knowledge and economics. The former is made operational through an analysis of co-occurrences of technological classes in patent documents in order to derive indicators of coherence, variety and cognitive distance. The...

This paper articulates an analysis of the co-evolutionary patterns of structural change in knowledge and economics. The former is made operationally through the analysis of co-occurrences of technological classes within patent documents, so as to derive the indicators of coherence, variety and...
