We study the relationship between decentralization of R&D, innovation and firm performance using a novel dataset on the organizational structure of 1,290 American publicly-listed corporations, 2,615 of their affiliate firms, as well as characteristics of 594,903 patents that they hold. We explore the tension between centralization and decentralization of R&D, which trades off between responsiveness to immediate and local business needs and the type of research that can benefit the firm as a whole. To do this, we develop two novel measures of decentralization. First, using intra-firm patent assignments, we distinguish between patents that are assigned to the inventing unit rather than to corporate headquarters. Second, we exploit the variation between firms which posses a central corporate ...

This paper examines the relation between ownership, corporate form, and innovation for a cross-section of private and publicly traded innovating firms in the US and 15 European countries. A striking novel observation emerges from our analysis: while most innovating firms in the US are publicly traded conglomerates, a substantial fraction of innovation is concentrated in private firms and in business groups in continental European countries. We find virtually no variation across US industries in the corporate form of innovating firms, but a substantial variation across industries in continental European countries, where business groups tend to be concentrated in industries with a slower and more fundamental innovation cycle and where intellectual protection of innovators seems to be of para...
