This paper applies nonparametric estimators to examine countries’ carbon dioxide (CO2) emissions and governance relationship. By using data for the time period 1996-2010 of the twenty largest economies (Group of twenty, G-20) the dynamics of the considered relationship are analyzed. Six...

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 proposes a conditional directional distance function model in order to examine the link between regional environmental efficiency and GDP per capita levels. As an illustrative example we apply our model to USA regional data revealing an inverted ‘U’ shape relationship between...

Based on the theoretical background of the link between countries’ transparency and environmental policy our paper provides empirical evidence for a sample of 68 countries for the time period of 2001-2010. By assuming that countries’ transparency levels shape their environmental policy which...

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 uses three different Malmquist Productivity Index (MPI) decompositions to measure Greek seaports’ productivity for the time period 2006-2010. In addition bootstrap techniques are applied in order for confidence intervals of the MPIs and their components to be constructed and...

This paper responds to the criticism of the Zubair Diminishing Balance model for Islamic home financing that Ahmad Kameel Meera published in the ISRA Journal. The response argues that most of the comments of Meera are frivolous and misplaced. It reiterates that the ZDBM is much different from...

The worldwide colossal failures of financial institutions in the wake of the 2007–2010 financial turmoil the yesteryear advocates of liberalization and privatization converted almost overnight into vocal supporters of raising the safety walls around the interests of various stakeholders,...

In this paper we apply an additive two-stage data envelopment analysis (DEA) estimator on a panel of 27 Annex I countries for the time period 2006-2010 in order to create sustainability efficiency indexes. The sustainability efficiency indexes are decomposed into economic and eco-efficiency...
