Abstract
The aim of this paper is to examine the impact of growing R&D cooperation networks on R&D knowledge spillovers and equilibrium outcomes. We find that as the cooperation in the network grows, the graph theoretic distances between competitors decrease. This allows the R&D spillovers between non-cooperators to increase. Moreover, we find that increasing the cooperation in the network improves the payoffs of firms. This indicates that developing the cooperation network is individually desirable to remain active in the industry.
