This paper investigates efficiency performance of thirty six banks operating in Gulf Cooperation Council (GCC) countries during the period 2006-2008 . Our results indicate in general GCC banks showed considerable pure technical efficiency in the past three years with the year 2007 exhibit the...

The passage of a technological process is carried out only in circumstances where the process is efficient in economic terms. Assessment of technological processes can be done by means of indicators which can be: economic, technical, economic and technical. Technical-economic indicators used in...

Economic efficiency plays an important role in the foundation and farm level decisions, constituting a basic criterion in assessing the level of economic activity and development prospects. The study aimed to analyze the economic efficiency of crop production systems, measured through indicators...

Abstract This study was undertaken with the goal of analyzing the relationship between poverty rates and size of underground economy in the developed and developing countries and exploring whether there is a link between them. There are technical problems in linking them in that getting...

There has been a lot of debate regarding the impact of emissions of pollutants on human health and the environment. Epidemiological studies tend to show the impact of increased ambient concentrations of pollutants on increased hospital admissions, mortality, morbidity, respiratory problems, etc....

Pena’s method of construction of a synthetic indicator is very sensitive to the order in which the constituent variables (whose linear aggregation yields the synthetic indicator) are arranged. Due to this, Pena’s method can at present give only an arbitrary synthetic indicator whose...

This paper uses mixed combinatorial-cum-real particle swarm method to obtain a heuristically optimal order in which the constituent variables can be arranged so as to yield some generalized maximum entropy synthetic indicators that represent the constituent variables in the best...

This work concerns the maximum flows – minimum cost problem and its main algorithmic solutions. Such a problem involves determining the least cost shipment of a commodity through a capacitated network in order to satisfy demands at certain vertices using supplies available at other vertices....

The aim of this paper is to develop a hedging methodology for making a portfolio of options delta, vega and gamma neutral by taking positions in other available options, and simultaneously minimizing the net premium to be paid for the hedging. A quadratic programming solution for the problem is...
