Note on the Excess Entry Theorem in the Presence of Network Externalities
| By: | Tsuyoshi Toshimitsu (School of Economics, Kwansei Gakuin University) |
| Abstract: | We reconsider the excess entry theorem in the presence of network externalities under Cournot oligopoly. We demonstrate that if the strength of a network externality is larger (smaller) than a half, the number of firms under free entry is socially too small (too large), based on the second-best criteria. |
