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.

Energy Consumption, Economic Growth and CO 2 Emissions in Middle East and North African Countries * This article extends the recent findings of Liu (2005), Ang (2007), Apergis et al. (2009) and Payne (2010) by implementing recent bootstrap panel unit root tests and cointegration techniques to investigate the relationship between carbon dioxide emissions, energy consumption, and real GDP for 12 Middle East and North African Countries (MENA) over the period 1981-2005.Our results show that in the long-run energy consumption has a positive significant impact on CO 2 emissions. More interestingly, we show that real GDP exhibits a quadratic relationship with CO 2 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 CO 2 emissions reduction via energy conservation without negative long-run effects on economic growth.

The article shows how new policy tools are designed in the Mediterranean countries for the monitoring of research and innovation. It relies on the results of a large European project, ESTIME, funded by the European Union that aimed at describing the state of research and technology policies and systems of partner countries in the Mediterranean. Other initiatives are also mentioned that aimed at gathering information on research and innovation systems in the Middle East and North African countries (MENA). The article presents the importance of the European Union as a reference for this monitoring activity. It also shows that the new tools, for example, innovation surveys, are a part of the policy process itself. Finally, it presents the main characteristics of public policies, their recent turn toward innovation and the effects that these policies have had on the institutions and actors promoting innovation which we propose to call the ‘innovation world’. Two examples are presented in more detail, Tunisia and Morocco, since both countries have been actively promoting innovation policies and have developed innovation surveys.

We investigate the existence of causal relationships between energy consumption and education (enrollment in primary secondary and higher education) for a sample of 16 African countries over the period 1971-2010 (according to availability of countries' data). We use the panel-data approach of Kónya ( 2006), which is based on SUR systems and Wald tests with country specific bootstrap critical values. Our results show that education and energy use are strongly linked in Africa. There is bidirectional causality between primary, secondary and higher education and energy use for several countries. Moreover, electricity consumption plays a crucial role in the energy-education links in Africa.
