Measuring economic journals’ citation efficiency: A data envelopment analysis approach
Halkos, George; Tzeremes, Nickolaos - Volkswirtschaftliche Fakultät, … - 2011
This paper by using Data Envelopment Analysis (DEA) and statistical inference evaluates the citation performance of 229 economic journals. The paper categorizes the journals into four main categories (A to D) based on their efficiency levels. The results are then compared to the 27 “core...

A variant of radial measure capable of dealing with negative inputs and outputs in data envelopment analysis
Cheng, Gang; Zervopoulos, Panagiotis; Qian, Zhenhua - Volkswirtschaftliche Fakultät, … - 2011
Data envelopment analysis (DEA) is a linear programming methodology to evaluate the relative technical efficiency for each member of a set of peer decision making units (DMUs) with multiple inputs and multiple outputs. It has been widely used to measure performance in many areas. A weakness of...

A UNIVERSAL SOLUTION FOR UNITS - INVARIANCE IN DATA ENVELOPMENT ANALYSIS
XU, Jin; ZERVOPOULOS, Panagiotis D.; QIAN, Zhenhua; … - In: Theoretical and Practical Research in Economic Fields III (2012) 2, pp. 124-131
The directional distance function model is a generalization of the radial model in data envelopment analysis (DEA). The directional distance function model is appropriate for dealing with cases where undesirable outputs exist. However, it is not a units-invariant measure of efficiency, which...

Measuring the effect of virtual mergers on banks’ efficiency levels:A non parametric analysis
Halkos, George; Tzeremes, Nickolaos - Volkswirtschaftliche Fakultät, … - 2010
This study illustrates how the recent developments in efficiency analysis and statistical inference can be applied when evaluating banks’ performance issues from a potential merger. By using a sample of 29 Greek commercial banks the paper provides a six step procedure in order to evaluate...
