Market Structure and Investment in the Mobile Industry

François Jeanjean (Orange Labs - Orange Labs [Belfort] - France Télécom) and Georges Vivien Houngbonon (LGI - Laboratoire de Genie Industriel - CentraleSupélec) analyze Market Structure and Investment in the Mobile Industry.

ABSTRACT: The impact of market structure, that is the number of firms and asymmetry , on investment is an important topic in the mobile industry. However, previous literature remains ambiguous about the direction of the relationship. This paper provides an empirical evidence of the impact of market structure on investment in the European mobile industry. The empirical assessment is based on a Salop model with vertical differentiation. Consistently with the prediction of this model, we find that both the number of operators and market share asymmetry have significant effects on investment. In symmetric markets, investment per operator falls with the number of operators, with larger effects for operators that lose market share more than the average. The industry investment rises with the number of operators in the short run, but eventually falls in the long run due to significant adjustment costs of investment in the mobile industry. These findings suggest that investment should be taken into account when analysing the welfare effects of market structure in the mobile industry.
