Yayın Renewable electricity consumption and economic growth nexus – evidence from high-,middle- and low-income countries(Işık Üniversitesi, 2024-01-23) Brown, Mustapha Abekah; Şen Taşbaşı, Aslı; Işık Üniversitesi, Lisansüstü Eğitim Enstitüsü, Uygulamalı Ekonomi Yüksek Lisans Programı; Işık University, School of Graduate Studies, M.A. Applied Economics Master ProgramRecent decades have witnessed growing concerns over sources of energy consumption and their role in economic development. Renewable energy and electrification have been touted by experts as a solution to mitigate these global issues. Considering this, the study investigates the intricate relationship between economic growth and renewable electricity consumption between the years 2000 to 2021 across a diverse spectrum of countries categorized by income levels. Renewable electricity consumption and economic growth data was collected for 48 countries. These countries were then further divided according to their income levels. The current study examines the relationship between renewable electricity consumption and economic growth through the lens of four distinct perspectives: the feedback hypothesis, the neutrality hypothesis, the growth hypothesis, and the conservation hypothesis. The Panel ARDL methods including the PMG, MG and DFE were employed to explore the presence of cointegration and the impact of renewable electricity usage on economic growth. The outcome of the methods indicate clearly that green electricity usage has a positive impact on economic growth across all income levels albeit at varying magnitudes. The findings contribute to the understanding of sustainable development and energy policies tailored to the specific economic contexts of countries at various income levels.Yayın Government expenditure and economic growth in Central and Eastern European economies: a panel ARDL approach(İstanbul Okan Üniversitesi, 2023-03) Görkey, SeldaThis study investigates the relationship between government expenditure and economic growth with a primary concern of focusing on the long-run effects. It uses the panel ARDL-PMG approach as an econometric methodology for 11 Central and Eastern Europe (CEE) economies from 1995 to 2019. The findings from the empirical analysis indicate a significant long-run relationship between the two macroeconomic variables; however, the relevant relationship is estimated negatively. The findings for the short-run effects for the whole panel and country-specific estimations also confirm that higher government expenditure results in a statistically significant decline in real GDP per capita. Thus, the findings of this study do not empirically validate the Keynesian theory for 11 CEE economies covered in the research over the 1995-2019 period.Yayın Renewable electricity consumption and economic growth: a cross-income panel ARDL analysis with implications for energy transition(İstanbul Okan Üniversitesi, 2025-06-02) Brown, Mustapha Abekah; Taşbaşı, AslıThe transition to renewable energy and the corresponding use of electricity generated from renewable sources is an inevitable solution that must be adopted to mitigate the effects of the climate crisis. The extant literature on the energy-economic growth nexus present mixed findings – some studies suggest the existence of a relationship while others find no significant relationship. Nevertheless, a growing number of recent studies provide evidence of an existing relationship. This study employs the panel ARDL techniques PMG, MG and DFE to investigate the short-run and long-run dynamics between renewable electricty consumption (RELC) and economic growth over the period 2000-2022 across 48 countries classified by income level. The results clearly indicate that the use of green electricity has a positive effect on economic growth across all income levels, albeit with varying magnitudes. Findings of the study provide particularly encouraging empirical evidence for a green transition in developing countries, underscoring the need for more attention to the unique challenges and opportunities faced by these economies.
