By using conditional directional distance functions this paper investigates the effect of regional economic growth on regions’ environmental efficiency in greenhouse gas emissions. A sample of ninety eight regions (NUTS 2 level) from Germany, France and the U.K. has been used and regional...

This paper examines the relationship between renewable energy consumption and economic efficiency. For this reason conditional Data Envelopment Analysis (DEA) estimators alongside with nonparametric regressions are applied in a sample of 25 European countries for the year 2010. Our results...

This paper by applying nonparametric techniques measures spatial environmental heterogeneities of 98 regions from Germany, France and the UK. Specifically environmental performance indexes are constructed for the 98 regions (NUTS 2 level) identifying their ability to produce higher growth rates...
