Impacto das fusões e aquisições na eficiência de instituições financeiras bancárias no Brasil

Abstract

The objective of this work is to compare the behavior of indicators of efficiency of acquirers and dominant financial institutions in M&A operations in Brazil before and after these transactions. To fulfill the objectives of this research an event study was performed considering sixty transactions between 1994 and 2012, which also considered 17 indicators classified in three categories: I- Profit Efficiency, II- Operational Efficiency and III- Managerial Efficiency. The comparison was made through parametric and non-parametric tests in order to identify significant changes in the cross sectional efficiency levels of the firms in the post-transaction moment. The results showed that for a significance ?=0.10, amongst the 17 variables, seven behaved diferently after the operations. Of the four ratios of the category I-Profit Efficiency, the one that presented significant changes performed worse in terms of Operating Profit on Total Assets. In regards to the eleven indicators of the category II- Operating Efficiency, there were five identified with significant variations, amongst them, the only one that showed improved efficiency was the ratio of Administrative Expenses on Credit Operations. On the other hand, the other four variables, Operating Expenses on Total Assets, Total Expenses on Total Assets, Expenses in Financial Intermediation on Debt, and Other Operating Expenses on Total Expenses showed reduction of operating efficiency. Last, for the category III-Managerial Efficiency, of its two indicators, only the indicator of Profits before Taxes on Equity demonstrated significant variations, which showed losses in terms of efficiency as well. The conclusions about the analysis of these variations suggest that, although M&A's motivations are frequently explained as a possibility of gain in terms of efficiency for the merged companies, it was not possible to find evidence of the predominance of these benefits in the Brazilian bank industry operations yet. It makes it necessary to perform additional research that investigates the possibility of the existence of other type of gains due to theses events.
