Dynamic Model in Estimating the Impact of Competition on Banking Efficiency: Evidence form MENA Countries

This paper investigates the role of competition in the Middle East and North Africa countries for the period of 2012-2021. The bank efficiency is measured using Stochastic Frontier Analysis. Using a sample of 177 commercial banks and a dynamic panel data approach in GMM technique, the empirical results revealed that the higher the competition the higher bank efficiency. This finding suggests that banks in countries with low high competition tend to perform more efficiently. Furthermore, a negative but insignificant relationship between total assets and bank efficiency reflects the fact that larger banks in developing countries suffer from diseconomies of scale.
