This paper investigates the interactive relationships between renewable energy and economic growth based on a Cobb-Douglas production function for Tunisia over the period of 1980-2011. Using an ARDL model, results show confirm the validity of the feedback hypothesis while in the short term the conservation hypothesis is supported. Based on the author's results, the Tunisian government is appealed to revise its policy toward the use of renewable energy by (i) the enforcement of the production and consumption of renewable energy to be substituted to the fossil and fuel energy and (ii) encouraging private sectors to deal with this energy subsector.

Purpose Despite an increasing volume of literature focussed on foreign direct investment (FDI) in transition economies, there has been little research into FDI in Ukraine. The relationship between the inflows of FDI (IFDI) and absorptive capacity (AC) has been under-researched in the peripheral transition countries like Ukraine. The purpose of this paper is to analyse the appropriateness of the Ukrainian economy’s AC to attract IFDI and facilitate economic growth with a particular focus on AC factors, such as the potential of human resources to absorb innovation and benefit from research and development (R&D) expenditure. Design/methodology/approach This study presents a thoughtful research design: there is an analysis of the AC framework for justification and selection factors that allows a measurement of the potential of Ukraine’s AC to attract and exploit IFDI. The study uses data from 25 regions in Ukraine for the 1996–2015 period. To estimate the effects of IFDI on Ukrainian economic growth, a Cobb–Douglas production function is used. As an appropriate instrumentation technique for dynamic panel data, the Generalised Method of Moments is used to provide unbiased and efficient estimates of the results. The application of the interactive term in this study allows the authors to indicate the existence of complementarities between IFDI and human capital, in particular with higher education, that afford opportunity to absorb new technologies and benefit from IFDI. Findings The resulting model indicates that R&D expenditure benefited very significantly in evolving country’s innovation system due to economic growth. Physical and human capital has not been used effectively in Ukraine to facilitate economic growth and attract IFDI. The number of patents is not significant in all of the regression models. Moreover, IFDI in Ukraine for the 1996–2015 period did not significantly impact on economic growth. However, the AC of human capital, in particular those with a higher education, is relatively relevant to benefit from IFDI. Practical implications The findings have important implications for governmental policy, which should be based on improving the business climate, a strategy for digital development, innovation, migration, institutional and regional policies aimed at the achievement of country’s sustainable economic growth. The government should increase R&D expenditure as an important factor of gross domestic product growth and introduce grants, loans and other financial supports for encouraging students to continue university education. Originality/value The originality and value of this paper is empirical and methodological. The empirical results of this study enable a conclusion about the appropriate level of the country’s absorptive capability required to benefit from IFDI. The paper also contributes to the existing academic debate and proves that despite the well-established theoretical framework for the IFDI–AC economic impact context, a new theorisation is needed to explore the full complexity of the country’s explicit relationship between AC and IFDI. Future research should be focussed on examining not only groups of countries but also distinctly the country’s explicit relationship between AC and IFDI with the particular attention for the under-researched countries: the peripheral transition economies to discover new research niches for theory building. This study presents an original methodological approach with a careful justification of the theoretical framework for hypothesis development, an appropriate sample and an original application of seminal research methods based on the Cobb–Douglas production function. This study proves that the interactive term, which allows indication of the existence of complementarities between IFDI and other variables, is appropriate for measuring AC in countries with smaller amounts of IFDI.

Purpose The purpose of this paper is to analyze the influence of the green talent dividend on China’s economic growth and regional differences using a theoretical derivation of the Cobb–Douglas production function. Design/methodology/approach This study develops a measurement model with human capital based on Chinese inter-provincial panel data for 2001–2017, and analyzes the influences on economic growth of employees’ education level, per capita material capital, green labor participation rate and green jobs. The study explores the impact of the green talent dividend on regional economic growth for different regions. Findings Employees’ education level, per capita material capital, green labor participation rate and green jobs promote China’s economic growth. The dependency ratio hinders economic growth. The green labor participation rate impacts economic growth more than green jobs do. Furthermore, the scale of green talent in China and its dividend effect are regionally unbalanced. Therefore, to fully release the dividend of green talent, the green labor participation rate should be improved to promote the rational flow of talent among regions. Practical implications These findings shed light on the talent dividend, provide a theoretical basis for the formulation of relevant talent policies, and show that the demographic dividend can be transformed into the green talent dividend, which has practical significance for the sustainable development of China’s economy given its aging population. Originality/value This study provides a macro perspective on the green talent dividend’s impact on economic growth. The Cobb–Douglas production function in this study differs from the traditional micro perspective on green labor.

This paper estimates the output Gap for Lebanon to analyze the economic policy and to judge the stance of the economy. Therefore, a Cobb-Douglas production function is estimated for the period Q11998 to Q42015 and potential output calculated by substituting for potential levels of the factors in the estimated production function. The calculation of potential labor required the calculation of the NAIRU. This paper calculates therefore three types of NAIRU. The results of output gap calculations show that the Lebanese economy is working over its capacity and that it hits his limits. Furthermore, findings show that the labor market is characterized by high levels of NAIRU which restricted potential output growth. Therefore, any policy aiming to increase economic growth, while neglecting structural reforms will prove to be unsustainable.
