by Sriganesh Lokanathan The study has been undertaken in keeping with the proposed 2006 theme of the World Dialogue on Regulation for Network Economies (WDR), ‘Sector and Regulatory Performance Indicators.’ The definition of standardized benchmark indicators with their respective viable methodologies in the Asian context is required for an accurate comparative analysis of the regulatory and sector performance in ICTs. Recognizing that this constitutes a participatory exercise among experts in the telecommunication industry standards and regulatory affairs, telecom authorities and statistical organizations as well as academics and interested individuals, this preliminary methodology framework document was commissioned to lay the groundwork to initiate and foster active discussion among the aforementioned participants on issues related to the proposed 2006 WDR theme. With these guiding principles, this preliminary methodology on domestic leased line tariffs was formulated since national leased line tariffs is an important indictor of the potential of countries to foster broadband coverage and network expansion. LIRNEasia intends to test the methodology first in the South Asian region and then extend it to the rest of Asia.
