This paper aims to determine the opportunity cost borne by US commercial banks to reduce non-performing loans (NPLs) by one unit within the global financial crisis framework.

To achieve this aim, the authors use the directional output distance function to estimate the technical efficiency while considering NPLs as undesirable output. Then, they estimate the shadow prices of NPLs by using the envelope theorem and solving the revenue function.

The results indicate that medium-sized banks are the most efficient, while small banks are the most inefficient ones. Moreover, the shadow prices of NPLs of large banks are higher than those of small and medium-sized banks. This implies a more elevated cost when lessening bad loans in large banks. This is more prominent during the crisis given that the shadow prices of NPLs of large banks have risen sharply over that period.

Shadow prices have important managerial implications given that they display the amounts of required reduced revenues to lessen NPLs. Accordingly, banks’ managers are called to reduce these loans by paying more attention when choosing their customers.

With the absence of an observable market price for bad loans in financial literature, the shadow price notion offers an adequate measure to evaluate them. To the best of authors’ knowledge, this is the first study that provides an estimation of the shadow price of NPLs in the US banking sector.

This study aims to discuss the determinants of Islamic banks’ efficiency. It tries to explore the source of Islamic banks’ inefficiencies to propose solutions to guarantee an acceptable level of technical efficiency of such banks in Gulf Cooperation Council (GCC) countries.

To achieve this objective, the authors use a parametric approach, especially, the stochastic frontier approach, using production function and panel data analysis. The authors apply a package Frontier 4.1 for the estimation process, which is composed of two principal steps. In the first step, the authors estimate Islamic banks’ efficiency scores in different GCC countries based on an output distance function. In the second step, the analysis highlights the impact of managerial-specific education on Islamic accounting and finance, scarcity of Sharīʿah scholars, the board independence and chief executive officers’ (CEOs) duality on GCC Islamic banks’ efficiency.

This study’s results document that managerial-specific education on Islamic accounting and finance and the board of directors’ composition, especially, the board’s independence, can largely explain the technical efficiency scores of Islamic banks in GCC countries. Especially, the authors find evidence that managerial-specific education is negatively associated with the inefficiency term. The coefficient of the Sharīʿah scholar’s variable has a positive sign indicating that the more there are Sharīʿah experts, the more the bank is efficient. In addition, CEOs’ duality seems to have no significant effect on GCC Islamic banks’ efficiency.

GCC Islamic banks need to improve the presence of independent members on the board of directors. In addition, these banks are invited to count more on Sharīʿah auditors and educated staff characterized by a high level of competency in the domain of Islamic banking and finance.

To the best of the authors’ knowledge, this is the first study that highlights the effect of managerial-specific education in Islamic accounting and finance and scarcity of Sharīʿah scholars on Islamic banks’ efficiency.
