This study examines variations in efficiency among hospitals located in western and southern Ukraine. We estimated efficiency using a nonparemetric modeling technique known as data envelopment analysis (DEA). DEA is a very powerful tool to compare relative efficiency among several economic units...

The purpose of this paper was to find out (using Regression, Data Envelopment Analysis and Sensitivity Analysis) how efficiently some of the top organized India retail companies have been performing relative to each other over the years and thereby to identify factors that help increase the...
