Resumo

The objective of this paper is to analyze the recent process of mergers and acquisitions in the brazilian economy, regarding their impacts on market concentration. Here, the correlations between the nature of the operation and some economic variables related to the firms are sought. From data of the judge reports of the Brazilian Competition Authority (CADE) about the concentration acts and the economic reports of the Economic Secretary on Competition of the Treasure Ministry (SEAE) about that cases, an econometric research is performed, using the logit model. The assumption is that operations with horizontal nature have greater impacts on market concentration than that with vertical and/or conglomeration nature. The outcome shows that the denationalization and operations in some sectors increase the concentration, whereas in global operations this effect is smaller.
