Abstract

The welfare effects of mergers in the mobile industry is the topic of an ongoing debate, however, there is still a lack of empirical evidence about the effect on consumer surplus. In this paper, we provide a simple structural model that accounts for investment in order to investigate the effect of mergers on consumer surplus in the mobile industry. Using a Cournot model with investment in cost-reducing technologies, and data on mobile Internet traffic from 18 European markets, we find that consumer surplus is maximized in markets with 3 symmetric operators. This finding accords well with a rising price per user and investment as a result of a merger. It suggests that, in mobile mergers, except 3-2 merger, dynamic efficiencies from investment outweigh static efficiencies from market power.
