Mobile Only Users Powered by Fixed-Mobile Substitution
France Telecom - Orange Group
August 10, 2012
In a context of partial fixed-mobile substitution, we analyze fixed-mobile bundling and mobile-to-fixed offloading in a duopoly model in which consumers buy one or two products. A joint purchase discount mitigates fixed-mobile substitutability and consequently reduces 'mobile-only' and 'fixed-only' consumers. Practices like introducing a small discount, applied on a bundle of multiple service or mobile-to-fixed offloading by both operators are analyzed. We find that such practices do not have negative impacts on the profits of whole market and lead to both consumers’ surplus and welfare gains. The investment incentives in fixed network are positive and can be boosted by FM bundling without considering regulatory intervention and before taking into account of fixed costs. The investment incentives in mobile network are more likely a situation of prisoners’ dilemma where operators should invest as long as there are 'mobile-only'-consumers.
