Going mobile: substitutability between fixed and mobile access

We empirically estimate the substitutability of fixed and mobile services for telecommunications access using a large, US household survey conducted over the period 2000-2001. Estimated cross-price elasticities confirm that second fixed line and mobile services are substitutes for one another. The extent of fixed-mobile substitution has important implications for policy toward fixed network unbundling, fixed-mobile vertical separation, and universal service.Telecommunications Access Mobile Demand Substitution

Going Mobile: Substitutability Between Fixed and Mobile Access

ABSTRACT: We empirically estimate the substitutability of fixed and mobile services for telecommunications access using a large, U.S. household survey conducted over the period 2000-2001. Estimated cross-price elasticities confirm that second fixed line and mobile services are substitutes for one another. The extent of fixed-mobile substitution has important implications for policy toward fixed network unbundling, fixed-mobile vertical separation, and universal service
