  THE IMPACT OF CLEAN ENERGY RESEARCH AND DEVELOPMENT, HEALTH EXPENDITURE, AND ECONOMIC GROWTH ON ENVIRONMENTAL QUALITY

  Al, I.; Akbulut Yildiz, G.; Yildiz, B.

  This study investigates the impact of clean energy technologies, health expenditure, and economic growth on environmental quality using the Fourier Engle-Granger cointegration method for the United States in the 1974–2022 period. The Fourier approach successfully identifies gradual structural shifts and nonlinear dynamics in long-run relations, which are frequent in macroeconomic and environmental time series but are typically overlooked by standard approaches. The findings show that clean energy research and development investment—specifically in energy efficiency, renewable resources, and nuclear technologies—and health expenditures significantly positively impact environmental quality. However, economic growth has a negative impact environmental quality in the United States. These results highlight the necessity of integrating environmental objectives into energy and health policy and prioritizing investment in sustainable technologies to achieve ecological sustainability in the long term.

  Relationship between Political and Financial Risks in Turkey: Evidence from Fourier Cointegration Analysis Regarding Institutional Structures; [Türkiye’de Politik ve Finansal Riskler Arasındaki İlişki: Kurumsal Yapılara Dair Fourier Eşbütünleşme Analizinden Kanıt]

  Çiçen, Yıldırım Beyazıt

  Institutional structure and quality of management are the main elements that form the political risks. Political threats are directly linked to the institutional structure and the institutional design. Political risks increase if the government mechanisms fail. Increasing institutional quality reduces the political risks and positively impacts the financial risks. Monthly data from different indices are used to analyse the relationship between Turkey's political risks and financial risks between 2002 and 2015. According to the Fourier analysis of cointegration, there is a long-term relationship between the political and financial risks. Besides, as per the Fully Modified Ordinary Least Squares (FMOLS) findings and the Dynamic Ordinary Least Squares (DOLS) models, an increase in the political risk increases the financial risk.
