Purpose – This paper aims to investigate the efficiency level of Gulf Cooperation Council (GCC) banks on technical efficiency (TE), pure technical efficiency (PTE) and scale efficiency (SE). Both PTE and SE represent the potential factors that influence the efficiency of the GCC banks. In total, 43 GCC banks were observed in this study over the period from 2007 until 2011. Design/methodology/approach – The Data Envelopment Analysis, a non-parametric method using variable returns to scale under Banker, Charnes and Cooper model, was used with assets and deposit (as input) and loan and income (as output). Findings – On average, the results show that many GCC banks are operating within an optimal scale of efficiency. Nevertheless, the results also show managerial inefficiency in the use of resources. Furthermore, the results indicate that, while the larger banks (the 22 largest) tend to operate at constant returns to scale (CRS) or decreasing returns to scale, the smaller banks (the 21 smallest) are susceptible to operate at either CRS or increasing returns to scale. Research limitations/implications – Because of the chosen research method, the results may lack generalisation. Therefore, researchers are encouraged to test the propositions further. An additional implication of the results is that it was able to identify some banks that may become potential targets for outside acquisition. Practical implications – The findings should be useful to banks in the GCC in increasing their efficiencies and recognizing those with a potential for outside acquisition. Originality/value – The findings are valuable because they will facilitate the maintenance of efficient banks in the GCC. This is necessary to enable the countries to maintain a healthy and sustainable economy.

Purpose – The purpose of this paper is to compare the development of accounting standards in five diverse Middle Eastern countries with those of the USA. Design/methodology/approach – A comparative analysis of each country with what is obtained in the USA. Findings – While there are some similarities that influence the development of accounting standards in each country, there also exist a variety of differences, particularly in the areas of taxation, use of International Financial Reporting Standards (IFRS), religion, population and so on. Research limitations/implications – The findings are limited to the five countries analyzed. Future research may want to expand the number of Middle Eastern countries included in the population studied. Originality/value – The study is original particularly due to the diversity of the countries selected. While the USA is an economically and technologically developed country, almost all of the other countries could be classified as developing. Additionally, the USA is the only country with its own uniquely developed standards, which are universally respected, but different from the single set of high-quality standards commonly referred to as the IFRS, which more than 100 countries have adopted.
