Motivated by the gained momentum of the sustainable development goals (SDGs) under the umbrella of the United Nations organization, in the light of the SDG‐7, which stipulates the access to affordable, sustainable, and modern energy, this paper explores the dynamic relationship between renewable energy and the pillars of sustainable development. It...

This analysis aims to treat the contribution of the foreign direct investment inflows and trade openness to environmental degradation.

For this purpose, our study uses the Johansen panel cointegration testing to verify the existence of long-run relationships and we employed the fixed effects models whi...

This paper has the aim to treat the interaction between the pillars of the sustainable development issue. We also attempt to build an index which is used as a measure of sustainable development by including good governance as the fourth pillar of sustainable development.

After the presentation of the theoretical framework lighting the main controversial issues related to the fundamental characteristics of African economy and theoretical bac...

The purpose of the current survey is to examine the presence of the resource curse mechanism for a panel of 22 African countries during the time span 1990–2013. For this purpose, our survey uses the Pedroni panel cointegration test to detect the existence of a long-run relationship, fully modified ordinary least square, dynamic ordinary least squar...

In line with the exogenous and endogenous theory coupled with the seminal Schumpeterian contribution, we attempt to investigate the impact of the use of internet and innovation on economic growth in the case of the Tunisian economy. For this purpose, we employ the ARDL bounds testing methodology over the period 1985-2018. In the short-run, our empi...

The reemergence of the resource curse issue as a stylized fact in the economies during the past two decades is due to the negative link between the growth rate and the resources abundance. The objective of this survey is to examine the relationship between oil rents, institution quality, and growth by applying the panel smooth transition regression...

The climate change issue becomes more challenging with the increasing pace of urbanization in Africa. For this purpose, we attempt to examine the relationship urbanization and CO2 emissions by applying the panel smooth transition regression model for 47 African countries during the spanning time 1990–2014. Our results reveal that the nexus between...

The development of endogenous growth theory has opened an avenue through which the effects of taxation on economic growth can be explored. Indeed, several empirical studies have examined the effect of many criteria, typically measured as domestic investment, on economic growth. This study reviews the theoretical and empirical evidence to assess whe...
