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 demonstrates an evaluation of 71 developed and under-developed countries’ biodiversity performance using a methodological framework based to the new advances of Data Envelopment Analysis (DEA). By using conditional DEA, bootstrapping and kernel density estimations, efficiency levels...

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 by analyzing the two popular methodologies of productivity measurement provides an example that illustrates the differences when adopting the two methodologies. Furthermore, under the restriction of constant returns to scale raises some methodological issues regarding the theory of...
