This chapter reviews academic research on the connections between agglomeration and innovation. We first describe the conceptual distinctions between invention and innovation. We then discuss how these factors are frequently measured in the data and note some resulting empirical regularities....

If it is largely assumed that space matters for innovation, theoretical understanding and measures of agglomeration remain a source of debates. This article proposes a review of the geography of innovation approaches through the balance between individual interactions and their context (between...

We analyze R&D collaboration networks in industries where firms are competitors in the product market. Firms' benefits from collaborations arise by sharing knowledge about a cost-reducing technology. By forming collaborations, however, firms also change their own competitive position in the...

This paper extends the existing literature on strategic R&D alliances by presenting a model of innovation networks with endogenous absorptive capacity. The networks emerge as a result of bilateral cooperation over time between firms occupying different locations in the knowledge space. Social...

In this paper we introduce a stochastic network formation model where agents choose both actions and links. Neighbors in the network benefit from each other's action levels through local complementarities and there exists a global interaction effect reflecting a strategic substitutability in...

Die Fähigkeit zur Einführung neuer Produkte und Verfahren ist in einer sich rasch wandelnden globalen Wissensgesellschaft zu einem entscheidenden Faktor für den wirtschaftlichen Erfolg geworden. Die Wachstumsperspektiven von Ländern und Regionen hängen in hohem Maße von ihrer Ausstattung...

Die Innovationskraft ist nicht nur für Nationen, sondern auch für Regionen eine elementare Voraussetzung für wirtschaftliche Leistungsfähigkeit und Wohlstand. Gemessen an der FuE-Beschäftigung im verarbeitenden Gewerbe ist die regionale Konzentration seit 1998 unverändert hoch. Mit großem...
