The OECD has declassified and made available its Indicators for the assessment of telecommunications competition (PDF).
- "Intensified competition in OECD countries’ telecommunications sectors calls for regulations proportionate to the level of competition in the market. If regulators consider there is full-fledged competition in a telecommunications market, they should lift regulatory interventions existing in the relevant market. Therefore, regulators need a yardstick that measures the true level and scope of competition. Regulators have not yet fully developed indicators for the assessment of telecommunications competition and thus have not reached a consensus on this issue. This report explores the concept of effective competition and the definition of a relevant market, and suggests appropriate indicators and parameters for the evaluation of competitiveness in the telecommunications markets."
