Ego-Network Stability and Innovation in Alliances

Pankaj Kumar, Akbar Zaheer · 2018 · Academy of Management Journal

Summary. This study examines how stable alliance networks affect firm innovation in biopharmaceutical companies. The researchers find that stable ego-networks actually reduce innovation outcomes. However, firms can mitigate this negative effect by spanning structural holes across their alliance partners. Geographic concentration of inventive activities in a single country worsens the innovation penalty from network stability.
