However, positive linkages between concentration/size and innovative activity can occur when certain conditions are met, including high sunk costs per individual project, economies of scale and scope in the production of innovation rents. Recent empirical work suggests that R&D intensity and market structure are jointly determined by technology, the characteristics of demand, the institutional framework, strategic interaction and chance ...
