The competition among mobile network operators in the telecommunication supply chain

A model has been defined to analyze the consequences of such diversity in the competition among HNOs, MNOs, and MVNOs by focusing the attention on the characteristics of the call path, in dependence of the types of operators. In fact, many variables interact to define the call path, such as marginal costs and revenues, infrastructural investments, and interconnection charges among operators. The analysis of the results, obtained by the model, gives information on variations of retail prices, market shares, and profit allotment, to adopt the proper strategies. In particular, the model results shed light on how certain MVNOs should enter the markets and adopt a collaborative strategy with HNOs. The model owns the capability of being applied to different contexts, thus representing for the regulator a potential instrument of relevant usefulness.
