Knowledge development and advice networks in professional organizations

In this paper, social network analysis techniques and regression models are used to explain the impact of the level of knowledge development on ego-network redun- dancy in a community of hospital physicians. Our findings document that the level of knowledge development and the extent to which knowledge is homogeneously distributed amongst collaborating physicians are related to the redun- dancy of their advice networks, albeit with opposite effects. Our results highlight also that the impact of these rela- tionships on network redundancy is moderated based on whether partnering individuals belong to different profes- sional groups. Our results provide valuable input for the management of knowledge networks within professional organizations.
