Abstract

The mobile telephony market can be characterized by a composition of homogeneities of products/services, with low conditions of product differentiation, determining the choices of consumers in this market. Thus, this study intends to analyze the market concentration and the structure of the cellular telephony sector by number of accesses of operators in the State of Ceará, for the years 2007 to 2015, through indicators that measure the concentration of being the Herfindahl-Hirshman Index (HHI) and the Concentration Ratio. With a quantitative approach, this research used secondary data available in the electronic portal of Teleco to analyze the behavior of the market shares of mobile telephony from Ceará, tabulated in spreadsheet and analyzed by means of graphs, tables and tables. In addition, three scenarios of merger simulations in the sector were presented, based on the results of 2015, considering the mobile telephony market in Ceará, in which two simulations indicated greater market concentration of the companies now merged. From the results, it was observed that the product or service marketed has a homogeneous characteristic, being the market characterized as oligopoly for having a limited number of operating firms and high market concentration, although with significant changes in the market.
