Abstract

This paper presents a Cournot oligopoly model with R&D spillovers both within and across industries. The aim is to provide a theoretical foundation for the main hypotheses regarding the impact of the local industry structure on innovation and output. Depending on the spillover rates and the degree of product differentiation between the industries, the firms respond differently to changes in variety and concentration, which can explain the mixed empirical results. Furthermore, innovation and output may react in opposite ways, which makes the choice of the performance measure critical.
