In Data Envelopment Analysis (DEA) context financial data/ ratios have been used in order to produce a unified measure of performance metric. However, several scholars have indicated that the inclusion of financial ratios create biased efficiency estimates with implications on firms’ and...

This paper uses both conditional and unconditional Data Envelopment Analysis (DEA) models in order to determine different environmental efficiency levels for a sample of 110 countries in 2007. In order to capture the effect of countries compliance with the Kyoto Protocol Agreement (KPA), we...

This paper analyses how European football clubs’ current value and debt levels influence their performance. The Simar and Wilson (J Econometrics, 136: 31–64, 2007) procedure is used to bootstrap the data envelopment analysis DEA scores in order to establish the influence of football clubs’...

This paper investigates the effect of energy consumption on countries’ economic efficiency. By using a sample of 18 EU countries for three census years (1980, 1990 and 2000) the paper employs conditional and unconditional robust nonparametric frontiers in order to establish such a...

Due to the fact that norms govern individual behavior, which in turn it is related to the environmental behaviour, this study tries to establish a link between human behavior (in terms of cultural values) and the environment. With the use of robust frontiers this paper constructs countries’...

This paper by using the system of LEAP (Long range Energy Alternatives Planning System) constructs four different energy scenarios for the Greek transport, energy and industry sectors. By projecting the renewable energy use for the years 2020 and 2030 and the associated resulting carbon dioxide...

The purpose of this paper is to construct the abatement cost curve for the Greek Energy and Industry sectors. To achieve our goal we present and analyze the abatement options available in the sector of energy and in the industrial subsectors of petroleum and gas refinery, cement and iron and...

This paper, by using conditional directional distance functions as introduced by Simar and Vanhems [J. Econometrics 166 (2012) 342-354] modifies the model by Färe and Grosskopf [Eur. J. Operat. Res. 157 (2004) 242-245], examines the link between regional environmental efficiency and economic...

This study examines the efficiency of banking systems in seventeen OECD countries over the period 1999-2009. For the purpose of our analysis we introduce a window-based version of two relational two-stage DEA models. Furthermore, we apply different versions of the additive and the multiplicative...
