The Efficiency of Strategic Management in Brazil: the case of the banking system
AbstractThis article examines the efficiency of the 50 largest financial conglomerates in the Brazilian retail banking system by total volume of assets, among those with at least 50 branches in the country, based on figures from their published annual reports for 2004. After providing a brief historical background, we use data envelopment analysis (DEA) together with the I-O stepwise technique for variable selection. We introduce into the analysis the creation and simulation of artificial or unobserved productive units (artificial decision making units). At the end we analyze the financial institutions according to the results presented by the nonparametric DEA method, using the artificial DMUs, to observe the units considered as efficient and the variables that the inefficient units need to work on to improve their performance.
