Bank Efficiency and Foreign Ownership in the Lebanese Banking Sector

What is it about?

We have compared the efficiency of banks with majority domestic ownership, banks with majority foreign ownership, and the subsidiaries of foreign banks operating in the Lebanese market between 1996 and 2005. We have implemented the DEA methodology to calculate the yearly scores for technical, allocative, and cost efficiencies for the three groups of banks. Moreover, we have extended our study to reveal the factors that shape bank efficiency, by proposing several micro- and macroeconomic variables and testing their correlation with this efficiency. Firstly, our results did not prove significant differences between the efficiency of the three groups of banks. However, the evolution of the efficiency scores over the period under study shows an improvement in the performance of banks with majority foreign ownership, but some deterioration in the performance of banks with majority domestic ownership and the subsidiaries of foreign banks. Secondly, and with respect to the factors affecting bank efficiency, we found that the employed variables have different impact according to groups, which may confirm that bank efficiency is differently determined, according to bank ownership.
