Efficient Components Pricing Rule (ECPR)
A methodology that addresses access pricing by emphasizing the opportunity cost of the integrated access provider. The relevant opportunity cost will depend on market conditions, including product differentiation, bypass, and substitution possibilities. In the most elementary situation, if the incumbent receives the same profits from interconnection and access as it does from sales of the retail product, the competition can enter the market only if they are more efficient in providing retail functions than the incumbent.
