TLDR
In this paper, a simple model of process innovation is proposed, where firms learn about their ideal production process by making prototypes and switch to mass-production and relocate to specialised cities with lower costs.Abstract:
A simple model of process innovation is proposed, where firms learn about their ideal production process by making prototypes. We build around this a dynamic general equilibrium model, and derive conditions under which diversified and specialised cities coexist. New products are developed in diversified cities, trying processes borrowed from different activities. On finding their ideal process, firms switch to mass-production and relocate to specialised cities with lower costs. When in equilibrium, this configuration welfare-dominates those with only diversified or only specialised cities. We find strong evidence of this relocation pattern in establishment relocations across French employment areas 1993u1996.read more

Knowledge and the diversity of innovation systems: a comparative analysis of European regions
TL;DR: In this paper, the authors proposed a more exhaustive effort in characterizing the diversity of regional knowledge an innovation systems within Europe through data analysis using the conceptual framework of social systems of innovation and production (SSIP) proposed by Amable, Barre and Boyer (1997).
Fiscal and growth spillovers in large urban areas
TL;DR: In this paper, the authors look for empirical evidence on spillovers occurring between central cities and their suburbs, both on the fiscal side and on the growth of population and output, and find that the capital stock in the central city promotes growth both in the city and in the suburbs.

Innovation in cities: Science-based diversity, specialization and localized competition
TL;DR: In this article, the authors consider the effect of the composition of economic activity on innovation and test whether the specialization of economic activities within a narrow concentrated set of activities is more conducive to knowledge spillovers or if diversity, by bringing together complementary activities, better promotes innovation.
