Central to this effort is understanding the role of environmental taxes and productive capacities in shaping environmental outcomes. Focusing on countries within the European Economic Area (EEA), this research uses advanced second-generation econometric techniques to examine this relationship. The use of cross-sectional autoregressive distributive lag (CS-ARDL) and dynamic common correlated effects (DCCE) models allows for a robust examination of panel data and provides reliable results. The results reveal an inverted U-shaped relationship, or Environmental Kuznets Curve (EKC), between GDP growth and environmental degradation in the EEA economies. Furthermore, while our data reveal a significant negative correlation between environmental taxes and CO2 emissions, we find that productive capacities have a more significant impact on reducing these emissions. These findings call for further research into the effectiveness of policies to support productive capacities in achieving environmental protection goals in the EEA.

Using a robust analytical framework consisting of the LMDI-II decomposition method, the Kaya identity, and the Tapio decoupling model, the study analyzes CO2 emission trends in Tunisia from 1980 to 2021. It identifies the main drivers of these emissions and provides insights into the complex relationship between demographic growth, energy consumption and economic activities. The chapter highlights several challenges linked to climate change and aims to provide a deeper understanding of how Tunisia can balance environmental needs with economic development, and ultimately propose targeted strategies and policy recommendations for sustainable growth and effective emissions reduction.

It situates the study within the broader discourse on sustainable development and economic growth, emphasizing the Environmental Kuznets Curve (EKC) framework to examine the relationship between economic development, characterized by urban expansion and increased productive capacities, and the adoption of environmental taxes amidst the continent’s diverse economic and environmental environments. Using advanced econometric techniques, including the Cross-Section Augmented Autoregressive Distributed Lag (CS-ARDL) model and the Dynamic Common Correlated Effects Mean Group (DCCEMG) estimator, the study addresses data challenges such as cross-sectional dependence and slope heterogeneity. The results provide important insights into the dynamics of environmental quality in relation to economic and urban growth and the role of environmental taxation. The study proposes tailored policy strategies aimed at strengthening sustainable development initiatives in line with international agreements such as the Paris Agreement and the Sustainable Development Goals. These strategies advocate for a nuanced application of environmental taxes and the promotion of productive capacities to enhance environmental sustainability across the African continent.

Therefore, this study empirically examines the impact of environmental fiscal policies, environmental technologies, and research and development (R&D) expenditures on achieving environmental sustainability in the G7 countries. Using advanced econometric techniques, including the Cross-Sectionally Augmented Autoregressive Distributed Lags (CS-ARDL) model and the Dynamic Common Correlated Effects (DCCE) approach, the study identifies both short-run and long-run correlations between the aforementioned variables and their impact on greenhouse gas (GHG) emissions. Our findings confirm the inverted U-shaped Kuznets Curve relationship and reinforce the previous literature on the complex dynamics between economic growth and GHG emissions specific to developed countries. The research also supports the effectiveness of well-designed environmental taxes in reducing environmental degradation and GHG emissions, consistent with and extending existing studies in this area. In addition, the study provides empirical evidence of the critical role of environmental technologies and targeted R&D expenditures in improving environmental quality. In terms of policy implications, our research underscores the urgency for policymakers in the G7 countries to fine-tune environmental taxation mechanisms and increase investment in sustainable technological solutions. Specific recommendations include the development of more efficient tax systems that adhere to the polluter-pays principle, as well as financial incentives such as tax credits and subsidies aimed at accelerating green technology adoption and innovation. In doing so, the study seeks to contribute to the broader discourse on environmental policy and sustainable development, providing valuable perspectives for both the academic community and policy actors.

Understanding the factors that influence the adoption of these platforms is essential for their continued development and widespread use. This study examines the determinants of economic platform adoption in Tunisia by extending the widely used unified theory of acceptance and use of technology 2 (UTAUT2) model with a privacy calculus model. By applying the partial least squares structural equation modeling (PLS-SEM) technique, the research provides significant insight. The results highlight the critical influence of factors such as performance expectancy, habit formation, trust in technology, perceived risk, privacy concerns, and price value on users' behavioral intentions and actual usage of the platforms. These findings provide a deeper understanding of the dynamics surrounding the adoption of the platform economy in developing countries and offer valuable insight for stakeholders. By leveraging this knowledge, stakeholders can foster an inclusive digital ecosystem, drive economic growth, and create an environment conducive to the widespread adoption and use of the platform economy in developing countries.

It employs a cross-sectional augmented autoregressive distributed lag (CS-ARDL) approach, an advanced technique for complex panel data that is specifically designed to address issues of cross-sectional dependence and slope heterogeneity inherent in panel data analysis. The research covers 88 countries, including both low-and middle-income countries (LMICs) and high-income countries (HICs), to understand how digitalization, as a driving force of the Fourth Industrial Revolution, interacts with environmental taxation and energy resource management to affect greenhouse gas emissions. The results reveal distinct effects of environmental taxes and energy capacity on environmental quality, with marked differences between LMICs and HICs. In HICs, technological progress, especially in information and communication technology (ICT), is found to contribute significantly to environmental quality. For LMICs, the effects are less evident, and the findings suggest the need for tailored strategies in environmental policy and energy management. By providing empirical evidence on the differential impacts of digitalization and energy policies in different economic contexts, this research enriches the environmental economics discourse. It highlights the need for policy frameworks tailored to specific contexts that effectively balance economic growth with sustainable development goals, thereby providing insightful implications for achieving the Sustainable Development Goals (SDGs).

The widespread use of technology in daily life, and particularly in education in higher education... more The widespread use of technology in daily life, and particularly in education in higher education institutions has devoted growing attention to the nature of ICT usages by Higher Education Teachers which has seen as an increasingly important factor for the successful integration of these technologies. This study aims to analyze the determining factors of the various uses of ICT by teachers in the university environment and to characterize their variety and intensity. For this end, we conducted a survey of a sample of 2,079 teachers from public universities in France. Our approach consisted in measuring the intensity of use of ICT in academia in order to appreciate the resulting digital divides between different groups of teachers. Multinomial logistic regression shows that the differences in the use of ICT are linked to the differences in initial digital skills between teachers. Furthermore, the training in ICT, age, gender and social context appear to have a manifold influence on ICT use. Our results clearly confirm the existence of digital divides, it prompts us to analyze more precisely the role of innovative users and that of first-time adopters when they appear to be actors involved in the diffusion of ICT within universities.

Applying logit, probit, and conditional mixed-process probit models to a sample of 807 Moroccan firms, we identify key factors that influence e-commerce adoption. The results show that younger, innovation-driven firms and those with a highly educated workforce tend to adopt e-commerce more readily. However, digital skills required in hiring do not significantly affect adoption, suggesting a complex relationship between digital skills and e-commerce use. The results also show that firms that are active on digital platforms and engage in innovative practices are more likely to adopt e-commerce. Therefore, this study argues for the need to improve digital skills training and for firms to establish a presence on digital platforms and promote innovation. On the policy front, the study suggests the promotion of supportive policies such as financial assistance, improved Internet infrastructure, and robust regulatory frameworks. As an important starting point for future research, these findings underscore the complexities of e-commerce adoption in Morocco and can guide further research, particularly in the context of similar emerging economies.

This paper examines the relationship between development of ICT and economic growth in Tunisia based on a sector analysis. We employ the common correlated effect mean group (CCEMG) and augmented mean group (AMG) methods and annual panel data for 1997 to 2017, to explore the relationship between ICT diffusion and economic growth in Tunisia. Our sector analysis shows that the effect of ICT on value added is heterogenous depending on the sector of activity and provides three main findings. First, in some sectors such as financial services, transport, building and civil engineering , hotel and restaurant services and other market services ICT have a positive and significant impact on value added. These sectors benefit from use of ICT. Second, in some sectors such as trade and various manufacturing industries, ICT has a negative and significant impact on value added. These sectors need to be well organized and well managed to avoid domination by informalities. Third, in some sectors such as public administration there is a productivity paradox and despite huge investment in ICT they have no impact on value added due to the absence of a deep organizational change.
