This paper develops the theory of a U relation between seller concentration and R&D investment and integrates the new theory with the traditional expectation of an inverted-U relation. The paper illustrates the U relation, and the integrated U and inverted- U relations, for a single type of R&D performed in most industries, exploiting differences in the degree of structural competition across industries while admitting little if any variation in the type of R&D.
Keywords: Innovation, inverted-U, research and development (R&D), seller concentration, Schumpeterian competition
