The Role of Social Networks on Regulation in the Telecommunication Industry
AbstractThis paper studies the welfare implications of equilibrium behavior in a market characterized by competition between two interconnected telecommunication ?rms, subject to constraints: the customers belong to a social network. It also shows that social networks matter because equilibrium prices and welfare critically depend on how people are socially related. Next, the model is used to study eÂ¤ectiveness of alternative regulatory schemes. The standard regulated environement, in which the authority de?nes interconnection ac cess charges as being equal to marginal costs and ?nal prices are left to the market, is considered as a benchmark . Then, we focus on the performance of two diÂ¤erent regulatory interventions. First, access prices are set below marginal costs to foster competition. Second, switching costs are reduced to intensify competition. The results show that the second strategy is more efective to obtain equilibrium prices closer to Ramsey?s level.
