Substitution Between DSL, Cable, and Mobile Broadband Internet Services

This article reviews substitution patterns on the market for broadband internet services in Austria. We present survey evidence and demand estimations which suggest that DSL and cable are part of the same market at the retail and at the wholesale level. Survey and estimation results from most other countries point in the same direction. We also consider substitution to mobile broadband via UMTS/HSDPA and describe recent developments in Austria which is one of the leading countries in the adoption of mobile broadband.
