Développement d'avantages concurrentiels dans les marchés des communications électroniques d'Amérique du Sud : Les cas de l'Argentine, du Brésil et du Chili

Abstract : The purpose of this thesis is to determine the presence of competitive advantages in Latin American Telecommunications markets. Most of major operators present in the region, including Telefónica and América Móvil, entered the market in favorable conditions when the industry was privatized in the early 1990s. In the past ten years markets have become more competitive due to changes in regulation. The analysis of the evolution of operators’ performances in this context allows to distinguish between those having actual competitive advantages and those having a strong market position thanks to their entry strategy. This thesis consists of five chapters. In chapters one and two we analyze the institutional context and the evolution of the telecommunications markets of each country. In chapter three, we determine that competition is characterized by facility-based entry in the three countries, which leads to disparities in terms of quality of service between operators. To determine if these disparities lead to competitive advantages, we test the presence of short and long-term relationships in the evolution of operators’ operating margins, and on stock market returns volatility. Our results indicate the presence of relationships in the evolution of operating margins, which suggests that differentiation is not strong enough to escape from competitive pressure. However, stock return volatility is higher among local operators than among multinational operators.
