Is Fixed-Mobile Substitution strong enough to de-regulate Fixed Voice Telephony? Evidence from the Austrian Markets

In this paper, we estimate own-price elasticities for fixed network voice telephony access and national calls services for private users as well as cross-price elasticities to mobile services using time series data from 2002-2007 from the Austrian market. Using instrumental variable estimates and considering cointegration, we find that access is inelastic while calls are elastic. We conclude th...

Fixed / Mobile Convergence : Aspects and Evolution of End-to-end Voice Performance in an Integrated Fixed and Mobile Network

IP-transport is a vehicle for integration of networks of different origins into a single entity. A new step in this evolution is the integration of fixed and mobile networks, not just at the service layer, but also at the infrastructure layer. Where such an integration for packet-based, non-real-time services looks evident, concerns exist about backward compatibility. In particular, the potenti...

Telecom Development in Korea: Substitution and Integration of Fixed-Mobile Services and Regulatory Implications

The past decade has seen phenomenal growth of mobile service in Korea. Growth in mobile services began to spurt in the late 1990s when all the other sectors of the economy were suffering the effects of financial crises and undergoing a painful restructuring process. Mobile infrastructure facilitated the fast flow of information among workers and investors and helped the economy to get over turm...

“ Usage Substitution between Mobile Telephone and Fixed line in the U . S . ”

We empirically estimate the substitutability of fixed and mobile services for telecommunications access using a large, U.S. household survey conducted over the period 1999-2001. We find significant positive cross-price elasticities between mobile and wireline usage. Because mobile usage prices fell dramatically over this period, we estimate that wireline usage may have been about 50% higher had...
