Abstract
This paper attempts to measure the cost efficiency of 44 banks
operating in Lebanon throughout the period 1992-2016, using the stochastic
frontier technique. The additional purpose of this study is to detect the
impact of some endogenous and exogenous factors on the cost efficiency scores
calculated. The empirical results show a stabilization in the cost efficiency
of Lebanese banks over the period studied and that on average those banks could
reduce up to 12% of their allocated resources while maintaining the same level
of their final outputs. We also found that cost efficiency among Lebanese banks
is driven by 1) macroeconomic factors such as economic growth and inflation
development and 2) by banks specific factors such as liquidity, capitalization,
profitability and the diversification strategy.
