Abstract

This paper provides a hedonic price analysis of mobile telephony services for the French market. We adopt the hedonic price theory to examine the relationship between changes in price levels and the evolution of the market for mobile telecommunications industry in France from June 1996 to December 2002. The results support the hypothesis that there was price competition between service providers in the earlier period. There were also large differences in prices set by individual service providers which, however, did not persist over time. Next, using estimates from hedonic-price equation for each operator separately, we found that the three-mobile providers seemed to adopt similar pricing strategies over the period 1996---2002. Quality indexes are also calculated. The results of a comparative analysis indicate that in the period 2000---2002 neither the quality nor the price indexes show significant changes for the three mobile providers. These results are of some consequence, especially after the French competition authority decision in December 2005 which stated the existence of collusion on the mobile market during the same period (2000---2002). Surprisingly, our primer results supporting the assumption of potential collusive conduct in France are not re-affirmed when comparing the French and German markets.
