Bank efficiency scores usually serve as a tool for comparing institutions with each other while allowing us to quantify sub-optimal decision-making unit choices. In the case of inter-country comparisons, such differences can also arise because of macro-economic heterogeneity between countries....

Purpose: 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. Design/methodology/approach: To achieve this aim, the authors use the directional output distance function to...

Purpose: 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....

This paper investigates profit efficiency and optimal production plan in European non-life insurance companies. To achieve our goal we have employed the directional output distance function in addition to the Lagrangian function that allows the specification of an optimal production plan for...

An optimal asset allocation is crucial for non-life insurance companies. The most previous studies focused on this topic use a mono-objective technique optimization. This technique usually allows the maximization of shareholders' expected utility. As non-life insurance company is a complex...

Practitioners and regulators increasingly rely on economic theory to measure bank efficiency and liken institutes with each other. These studies lean first on several methods that could be either stochastic or deterministic and second the input-output definition is based on a production or...
