This paper analyzes how competition works in mobile telecommunications markets and, based on this analysis, we discuss whether regulatory intervention in mobile telephone markets is justified from an economic perspective.

Hence, a key determinant for mobile operators' price policy lies in their cost structure, which is characterized by high fixed and common costs that are also sunk and relatively low incremental costs.
