Our results show that in the long-run energy consumption has a positive significant impact on CO2 emissions. More interestingly, we show that real GDP exhibits a quadratic relationship with CO2 emissions for the region as a whole. However, although the estimated long-run coefficients of income and its square satisfy the EKC hypothesis in most studied countries, the turning points are very low in some cases and very high in other cases, hence providing poor evidence in support of the EKC hypothesis. Thus, our findings suggest that not all MENA countries need to sacrifice economic growth to decrease their emission levels as they may achieve CO2 emissions reduction via energy conservation without negative long-run effects on economic growth.

The study uses commune fixed-effect regressions to estimate the effect of natural disasters on household welfare and poverty, and subsequently examines household and community characteristics that can strengthen resilience of households to natural disasters. We find that all the three disaster types considered in this study including storms, floods and droughts have negative effects on household income and expenditure. Access to micro-credit, internal remittances and social allowances can help households strengthen the resilience to natural disasters. Households in communes with higher expenditure mean and more equal expenditure distribution are more resilient to natural disasters.

The role of innovation and institutional quality for achieving sustainability are important issues tackled by current sustainable development debates, particularly in developing countries. Using a modified environmental Kuznets curve model, the present study improves our understanding of the critical roles of innovation, institutional quality, and entrepreneurship in structural change toward a sustainable future for Africa. Our empirical results show that formal and informal entrepreneurship are conducive to reduced environmental quality and sustainability in 17 African countries however informal entrepreneurship contributes more than formal entrepreneurship to this environmental degradation. The relationship between entrepreneurship and sustainable development turns strongly positive in the presence of high levels of innovation and institutional quality. This study contributes to this emerging research strand by clarifying the conditions that allow African countries to move toward more sustainable economies. Our results highlight the important roles played by innovation and institutions for achieving sustainability in Africa.

This paper provides an extensive survey of the great progress in the literature of energy-environment-growth nexus for both specific-and multi-county studies covering the period from 1978 to 2014. The survey focuses on country (ies) coverage, periods, modeling methodologies, and empirical conclusions. Our survey is based on the direction of causality between (i)energy consumption (electricity, nuclear, renewable and non-renewable) and economic growth; (ii) between economic growth and environment; and between the three variables at the same time. As a general remark from these studies is that the literature produced paradoxical and not conclusive results which energy consumption can boost economic growth through the productivity enhancement and it can boost also the environmental damages through the enhancement of pollutant emissions. This survey gives researchers a 'snap shot' of the literature on the causality between the four types of energy, environment and economic growth for both individual and collective cases. Understanding the causal links between environment, economic growth and different types of energy consumption provides a basis for discussion in order to design and implementating effective energy and environmental policies.

This paper contributes to the urbanization-poverty nexus by assessing the effect of urbanization on income, expenditure, and poverty in rural households in Vietnam, using data from household surveys. We find that the urbanization process stimulates the transition from farm to non-farm activities in rural areas. More specifically, urbanization tends to reduce farm income and increase wages and non-farm income in rural households. This suggests that total income and consumption expenditure of rural households are more likely to increase with urbanization. Finally, we find also that urbanization helps to decrease the expenditure poverty rate of rural households, albeit by a small magnitude.

Driven by Information Technologies (IT), universities are changing in depth the nature and forms of learning processes, which are intended to prepare students to a better entry into the labour market. In this paper, we focus on the evolution of students' use of IT in such an institution characterized by organizational changes and we analyse the determinants of students' e-skills using a dataset of French university students. We show that students' involvement in the use of IT increases their e-skills. IT learning by doing and IT learning by using also increase some categories of students' e-skills. In addition, collaborative and cooperative learning are positively associated with students' advanced e-skills.

Information and communication technologies (ICTs) are an integral part of our environment, and their uses vary across generations and among individuals. Today’s student population is made up of “digital natives” who have grown up under the ubiquitous influence of digital technologies, and for whom the use of ICT is common and whose daily activities are structured around media use. The aim of this study is to examine the impact of ICT use and digital skills on students’ academic performance and to explore the digital divide in France. Data were collected through face-to-face questionnaires administered to 1323 students enrolled in three French universities. Principal component analysis, a non-hierarchical k-means clustering approach and multilevel ordered logistic regression were used for data analysis and provide four main findings: first, poor investment in ICT affects students’ results; second, the ICT training offered by universities has little impact on students’ results; third, student performance improves with the innovative and collaborative use of ICTs; fourth, the acquisition of digital skills increases students’ academic performance. The results show that the digital divide still exists, and this raises questions about the effectiveness of education policies in France. They suggest also that organizational change in universities is essential to enable an exploitation of ICT.
