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...

This paper examines the impact of natural gas consumption, real gross fixed capital formation and trade on the real GDP in case of Tunisia over the period of 1980-2010. We used Auto-Regressive Distributed Lag (ARDL) bounds testing approach to test the existence of long run relationship between...

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 examines the impact of natural gas consumption, real gross fixed capital formation and trade on the real GDP in case of Tunisia over the period of 1980-2010. We used Auto-Regressive Distributed Lag (ARDL) bounds testing approach to test the existence of long run relationship between...

Using time series data, this paper investigates China’s carbon emissions during 1960-2006, with particular focus on the direct role of growth and in connection to trade and the value added by various sectors like agriculture, industry and services. Our empirical results indicate the presence...

By applying conditional and unconditional data envelopment analysis (DEA) models along side with statistical inference using bootstrap techniques; this paper investigates the link between China’s carbon dioxide emissions (CO2) environmental efficiency and its economic growth (measured in GNI...

This paper applies a probabilistic approach in order to develop conditional and unconditional Data Envelopment Analysis (DEA) models for the measurement of sectors’ input oriented technical and scale efficiency levels for a sample of 23 Greek manufacturing sectors. In order to capture the...

Research is an original contribution to the existing stock of knowledge and it is a powerful tool for knowledge generation. A newly born nation Eritrea has been facing number of challenges in research and development particularly the challenge of applying knowledge to work in the economy....

The poverty problem is chronic in the Horn of Africa. Majority of the people in the region are suffering from this problem. There are numerous factors that cause poverty in the region. The challenge of poverty reduction in the Horn should therefore address the poverty reduction issues at...
