How large is the magnitude of fixed-mobile call substitution? Empirical evidence from 16 European countries
Posted by D. Daniel Sokol
Anne-Kathrin Barth, Duesseldorf Institute for Competition Economics and Ulrich Heimeshoff, Duesseldorf Institute for Competition Economics provide analysis on How large is the magnitude of fixed-mobile call substitution? Empirical evidence from 16 European countries.
ABSTRACT: This paper investigates the degree of fixed-mobile call substitution (FMCS). We use quarterly data from 2004 to mid 2010 on 16 mainly Western European countries. By applying dynamic panel data techniques, we are able to estimate short-and long-run elasticities. The own-price and cross-price elasticities found give strong empirical evidence for substitutional effects towards mobile services. In particular, the estimated cross-price elasticities of the mobile price on the fixed line call demand are relatively large compared to other studies.
