We identify sufficient conditions for existence of competitive equilibrium with network externalities and indivisibilities. Such combination of externalities and indivisibilities is present in many goods and services with network effects, and it makes existence of equilibrium non-trivial. We provide an existence theorem in a model with a measure space of consumers. Key conditions for existence are anonymity of network effects and dispersion in the economy’s income distribution.

具有网络外部性的竞争性一般均衡

我们确定了存在网络外部性和个体性的竞争均衡的充分条件。外部性和不可分割性的这种结合存在于许多具有网络效应的商品和服务中，并使均衡的存在变得不平凡。我们在具有消费者度量空间的模型中提供了一个存在定理。存在的关键条件是网络效应的匿名性和经济收入分配的分散性。
