This paper uses Data Envelopment Analysis (DEA) model formulations in order to determine the performance levels of 16 departments of the University of Thessaly. Particularly, the constant returns to scale (CRS) and variable returns to scale (VRS) models have been applied alongside with bootstrap...

This article uses Data Envelopment Analysis (DEA) in order to determine the performance levels of 16 departments of a public owned university. Particularly, the constant returns to scale (CRS) and variable returns to scale (VRS) models have been applied alongside with bootstrap techniques in...

This paper uses a sample of 36 countries for the time period 1990–2011 in order to examine the relationship between countries׳ electricity consumption from renewable sources and Gross Domestic Product (GDP) levels. Several nonparametric techniques are applied to investigate the effect of...

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] and examines the link between regional environmental efficiency and...

Based on the theoretical background of the link between countries’ public sector transparency and environmental policy, our paper provides empirical evidence for a sample of 49 countries for the time period of 1995–2000. Assuming that countries’ environmental performance is a product of...

This paper applies a bootstrapped Data Envelopment Analysis (DEA) formulation aiming to evaluate the financial performance of the firms operating in the Greek renewable energy sector. With the use of financial ratios in a DEA setting, efficiency ratios are constructed in order to analyse...

This paper deals with the effects of EMU enlargement (European Economic and Monetary Union) by evaluating the economic efficiency of growth policies of the 25 member countries. By using Data Envelopment Window Analysis the paper measures the policies adopted initiating economic growth of the 25...

By using a sample of 77 countries the analysis applies several nonparametric techniques in order to reveal the link between national culture and corruption. Based on Hofstede΄s cultural dimensions and the corruption perception index, the results reveal that countries with higher levels of...
