Network structures reside at various levels of analysis within (and between) organizations. Similarly, these networks affect performance at various levels. This research program moves between these levels of analysis and explores and systematizes how firm level findings can be employed to study and improve team level performance and vice versa. In addition to the 'pink glasses' approach of much of the networks literature, the present research also explicitly studies when and how social networks impede performance rather than facilitate |
