Intervenção regulatória nos setores de telecomunicações e elétrico em 2012um estudo de eventos com modelo de precificação multifatorial

Resumo

We analyze the effect of two 2012 regulatory measures in the Brazilian telecommunications and electricity markets. The first intervention was undertaken by the telecommunications regulatory agency (Anatel) on July 18 and refers to the interruption of the sales of important telecommunications mobile companies due to the poor quality of their services. The second one was undertaken by the Brazilian electricity regulatory agency (Aneel) on September 11 and consists of the definition of the rules governing the renovation of generation and transmission concessions (MP579). We apply a multifactorial pricing model and event studies techniques and we find negative effects of both regulatory interventions in their respective markets. However, the market reaction to the second one seems to be efficient since the prices fell abruptly afterwards. This quick response might be either related to the particular characteristics of the MP579 or to a market perception towards an increase of regulatory intervention due to the previous measure in telecommunications.
