Comparação da Eficiência de Custo para BRICs e América Latina
The purpose of this research is to evaluate the banking structure of the four major emerging economies (Brazil, Russia, India and China - BRIC), and Latin American countries. We employ a stochastic frontier model to estimate the values of cost efficiency and compare these efficiency measures among these countries. Additionally, we assess the changes in efficiency due to the inclusion of non-traditional activities (non-interest income). The results show that the efficiency of these countries has increased in the recent period and that the inclusion of variable non-traditional activities increases average bank efficiency, with the exception of the banking system of Russia.
