This paper studies the role of intrinsic motivation, reputation, and reciprocity in driving open source software innovation. Unlike previous literature based on survey data, we exploit the observed pattern of contributions - the .revealed preference. of developers - to infer the underlying...

The primary goal of this paper is to improve our understanding of the complex relationship between the positioning of companies in alliance networks and their innovative performance. In particular, we expect that a firm's innovative performance depends partly on its position in specific network...

In this note we examine whether a position in a technology alliance block is accessible to everyone. It appears that partners are selected on the basis of distinctive attributes they have, which can inhibit outsiders to join these alliance groups. Our findings clearly indicate that alliance...
