The purpose of this paper is to provide an in-depth analysis, using both financial ratio analysis and data envelopment analysis (DEA), of a consistent sample of Islamic and conventional banks located in the GCC region over the period 2004 to 2007. Results from the financial ratio analysis...

Several recent studies advocate the use of nonparametric estimators of daily price vari- ability that exploit intraday information. This paper compares four such estimators, realised volatility, realised range, realised power variation and realised bipower variation, by examining their in-sample...

As student numbers in the UK's higher education sector have expanded substantially during the last 15 years, it has become increasingly important for government to understand the structure of costs in higher education, thus allowing it to evaluate the potential for expansion and associated cost...

Cost functions are estimated, using both random effects and stochastic frontier methods, for institutions of higher education in England. The paper advances on the existing literature by employing finer disaggregation by subject, institution type, and location, and by introducing consideration...

Recent work on business strategy considers the evaluation of company performance using frontier methods (Devinney et al., forthcoming). The present paper builds on that work to examine the extent to which company performance in one period impacts on business practices and hence performance in...

HEIs are likely to face tight fiscal constraints in the future. This paper uses random effects and stochastic frontier techniques to estimate an output distance function over the period 1997/97 to 2007/08 in order to investigate the efficiency of higher education institutions (HEIs) and to...

This study uses data for more than 500 Further Education providers in England to investigate the level of efficiency and change in productivity over the period 1999-2003. Using Data Envelopment Analysis we find that the mean provider efficiency varies between 82% and 86% over the period....

This study uses data envelopment analysis (DEA) and a distance function approach to derive Malmquist productivity indexes for 113 English higher education institutions (HEIs) over the period 1996/97 to 2002/03. The analysis finds that over the period of the study HEIs have experienced an annual...
