This study evaluated efficiency of private and government banks using Data Envelopment Analysis with Assumption of a constant and variable return to scale. The statistical study included nine government and six private banks taken from the period of 2006-2010. Total expenditures and deposits as...

We consider efficiency measurement methods in the presence of uncertain input and output data, and without the (empirically problematic) assumption of convexity of the production technology. In particular, we perform a simulation study in order to contrast two well-established methods, IDEA and...

In the current study, the general fuzzy data envelopment analysis (GFDEA) approach is presented for stock evaluation under data ambiguity and linguistic variables. It should be explained that to propose GFDEA method, data envelopment analysis (DEA), possibilistic programming approach (PPA),...

Objective - The banking sector plays an important role in the Indonesian economy. The sustainability of the Indonesian banking sector will depend on the ability of every banking institution to maintain their competitiveness. Banking competitiveness is reflected in the level of efficiency of the...

Active portfolio managers are eager to predict future volatility in the returns of schemes. Returns of each scheme are tracks with the returns of respective bench mark, technically called as tracking error. Ex-ante tracking error plays a crucial role in predicting future performance of the...

Background: In recent years, measuring and evaluating the efficiency of health systems has been explored in the context of seeking resources to ensure the sustainability of 'countries' health and social systems and addressing various crises in the health sector. The study aims to quantify and...

Within the political, scientific and economic debate on climate change, the process of evaluating climate policies ex-ante, during and/or ex-post their lifetime, is receiving increasing attention from international institutions and organisations. The task becomes particularly challenging when...

German savings banks play a key role in financing German SMEs. Accordingly, the analysis of their efficiency is of economic importance. We apply data envelopment analysis to explore the influence of the financial crisis (2007 to 2008) as well as the Eurozone crisis (since the end of 2009) on the...

There are some specific features of the non-radial DEA (data envelopment analysis) models which cause some problems under the returns to scale measurement. In the scientific literature on DEA, some methods were suggested to deal with the returns to scale measurement in the non-radial DEA models....

Data Envelopment Analysis (DEA) is often used by regulators to create a pseudo-competitive environment for sectors with natural monopolies. In addition to develop a theoretically well-behaved model, regulators need to take into account several other factors, such as the political agenda and the...
