Abstract: | It has been argued that access charges may be set optimally by applying the Efficient Component Pricing Rule (ECPR). The paper
analyzes the optimality properties of the ECPR in the presence of network externalities in the telecommunications sector.
It is assumed that network externalities in the fixed telephony, which is operated by an incumbent monopoly, may arise from
the increase in the number of subscribers of a mobile carrier that seeks interconnection to the fixed network. It is shown
that the optimality properties of the ECPR that may exist under some restrictive assumptions, do not hold in the presence
of network externalities. Specifically, the ECPR may take into account the social opportunity cost with the entry of the competitor,
but it fails to incorporate the social benefit accrued to consumers of the fixed telephony when network externalities are
present.
