Abstract: This paper presents micro-econometric evidence for collaborative knowledge creation at the level of individual researchers. The key determinant for developing new ideas is the exchange of differentiated knowledge among collaborators. To stay creative, inventors seek opportunities to shift their technological expertise to unexplored niches by utilizing the differentiated knowledge of new collaborators. Moreover, the knowledge stock of an inventor, proxied by the scope of an inventor’s past research, has positive and negative effects on their productivity. This is because it facilitates successful collaboration; however, simultaneously, the dependence on older knowledge hinders invention possibly due to the obsolescence and exhaustion of niches by imitation.
