In this paper we use the Data Envelopment Analysis (DEA) window method to compare trade efficiency for 16 OECD countries and for the time period 1996–2000. From the analysis we obtained the efficiency scores and the optimal output levels for inefficient countries for all years under...

This paper measures the effect of different socioeconomic determinants on countries’ transparency efficiency. Specifically, using Data Envelopment Analysis (DEA), the transparency efficiency of twenty nine countries is calculated. Then with the help of factor analysis we extract two factors...

This paper evaluates the effect of access to improved water sources and sanitation on 41 sub-Saharan African (SSA) countries’ economic efficiency and growth. For this reason Data Envelopment Analysis (DEA), bootstrap techniques and probabilistic approaches are used. The empirical results...

This paper by performing a bootstrapped Data Envelopment Analysis (DEA) tries to constitute to the existing literature by investigating if firms’ internationalization levels have an impact on their performance. Using a sample of ten Transnational corporations from South-East Europe the paper...

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 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...
