We provide a simple model of endogenous product compatibility choice under Cournot competition with a network externality. Using the model, we consider how the degree of a network externality and product substitutability affects the choice regarding product compatibility. In particular, if the...

This paper formulates a reciprocal market model of international duopoly with network externalities to reconsider welfare effects of reductions in transport costs and tariffs. Depending on the magnitude of network externalities, we show two possibilities. One of them, which emerges under strong...

Introducing product compatibility associated with network externalities (hereafter, network compatibility effects) into a horizontally differentiated duopoly model, we consider how network compatibility effects and the level of product substitutability affect endogenous timing decisions in the...
