摘要：The objective of this study is to analyze the productivity growth of Togolese banks. The study period (2000-2008) corresponds to the post-financial liberalization in the West African Economic and Monetary Union (WAEMU) zone and the third phase of a changed banking and financial environment. We develop a new combined Malmquist index based on 'P-index ll' in order to estimate the total factor productivity (TFP) growth and its components. The empirical results show that the TFP has considerably increased for the whole industry, in which technical change is found to be a more important source of productivity growth to Togolese banks compared to efficiency change. In line with this, it is indicated that the financial liberalization does not improve the technical efficiencies of banks in Togo on a whole.
