This paper considers the collusive stability of downstream competition in a vertical market with network externalities … perfect Nash equilibrium. We show that larger network externalities lead to less collusive incentive for an inefficient firm …, while for an efficient firm, this depends on the efficiency gap. An increase in network externalities will destabilize the …

In this paper, we examine how the introduction of network externalities impact an open and vertically integrated …

. Finally, the quantitative analysis, based on structural equation modeling, yields the conclusion that network externalities …
