Mobile Termination Rates and Retail Regimes in Europe and the US: A Unified Theory of CPP and RPP

Trabajo presentado de forma online en el Microeconomic Research Unit (MRU) Seminar, organizado por la Universidad de Copenhagen (Dinamarca), el 17 de noviembre de 2020We analyze an oligopoly model where mobile operators may charge subscribers for placing and receiving calls. We compare the CPP equilibrium (where receiving calls is free) with the RPP equilibrium (where placing and receiving calls are priced equally). Reducing termination rates leads to lower prices and higher penetration under CPP, but has reversed effects under RPP. No termination rate yields efficiency under either retail regime. Comparing EU practice (CPP with termination regulated at cost) and US practice (RPP with Bill and Keep), we find higher producer and consumer surplus in the former for intermediate values of call externality. However, if call externality is higher (resp., lower), consumers (resp., producers) are better off in the US
