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...

We investigate the procedure used by Ané and Geman (2000) to recover the moments of the information flow from high frequency data, in a model which generalizes the subordinated process in Clark (1973). We explain why the third and higher moments of the latent information flow cannot be...

We investigate the bootstrapped size and power properties of five long memory tests, including the modified R/S, KPSS and GPH tests. In small samples, the moving block bootstrap controls the empirical size of the tests. However, for these sample sizes, the power of bootstrapped tests against...

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...

This study uses data envelopment analysis (DEA) to examine the relative efficiency of over 100 selected Chinese regular universities. Various models are developed to measure the research efficiency of these higher education institutions (HEIs) using data for 2003 and 2004. The findings show that...

Data envelopment analysis (DEA) and multilevel modelling (MLM) are applied to a data set of 54578 graduates from UK universities in 1993 in order to assess the teaching performance of universities. A methodology developed by Thanassoulis & Portela (2002) allows each individual's DEA efficiency...
