Health Capital and a Sustainable Economic-Growth Nexus: a High-Frequency Analysis During Covid-19
(Mdpi, 2024) Sungur, Nazli Ceylan; Akdogan, Ece C.; Gokten, Soner
The recent COVID-19 pandemic effectively concretized the vitality of health expenditure and the economic-growth nexus, and the threat of new pandemics make re-examining this relationship a necessity. Consequently, this paper focuses on this nexus for developed OECD countries, paying particular attention to the effects of the COVID-19 pandemic. The use of stock indices as proxy variables for health expenditure and economic growth enabled the examination of this nexus by using high-frequency data and financial econometric techniques, specifically via rolling correlation and bivariate GARCH analyses. The data span 1170 observations between 15 May 2018 and 11 November 2022. Since the research period overlaps with the outbreak of Ukraine-Russia war, additional insights are obtained regarding the effects of the war as well. It was found that an increase in health expenditure leads to a delayed increase in economic growth even in the short term, and this relationship mainly develops during crises such as epidemics, wars, supply chain breakdowns, etc., for developed OECD countries. Given the aging population of developed countries, which will probably deteriorate the health status of those countries in the near future, the increasing political tensions around the globe and the considerations of a global recession highlight the importance and the inevitability of investments in health capital for developed countries as well.

Managing working capital efficiency in Turkish agribusinesses and the impact of globalization: insights from an emerging market
(Wageningen Academic Publishers, 2019) Akdogan, Ece C.; Akdoğan, Ece Ceylan; Dinc, Dilek Temiz; 52039; Bankacılık ve Finans
The efficiency of working capital is a major determinant of firm profitability. So, the grasp of working capital dynamics is extremely important for managers, but also for policy makers, since inefficient working capital management is an important source of industrial sickness. This study focuses on the profitability impacts of working capital policies of Turkish agribusinesses, and aims to investigate the potential effects of globalization on these interrelated relationships. The findings obtained from pooled panel analyses demonstrate that Turkish agribusinesses can enhance their profitability and value by adopting a conservative working capital policy through lengthening the cash conversion cycle up to an optimal level. Besides, globalization is found to deteriorate their efficiency and profitability where economic globalization seems to have the highest impact raising questions on the effectiveness of Turkish agribusinesses in coping with competition. Thus, both the managers and the policy makers should concern with the competitiveness impacts of globalization.

Profitability effects of financial globalization in an emerging market banking industry: insights into Turkey
(Univ Rijeka, Fac Ecomomics, 2019) Akdogan, Ece C.; Akdoğan, Ece Ceylan; Ozsuca, Ekin Ayse; 237965; Bankacılık ve Finans
The massive ,financial liberalization followed by accelerating financial globalization leaded to significant structural changes in the financial sector: Since financial institutions play a dominant role in functioning of financial sector, especially in emerging markets where banking industries are generally among the most sensitive sectors to increased interconnectedness of financial markets, haw financial globalization actually affects the efficiency of financial intermediation is a vital question. However; although there exists plenty of research focusing on financial integration, impacts of financial globalization is untouched. Hence, this study investigates the bank profitability effects of financial globalization through focusing on an emerging market, Turkey and searches for any potential differences that may prevail among banks with different ownership structures. The findings indicate that while the market based profitability measures improve with financial globalization, the accounting based measures deteriorate pinpointing to an over optimism in the market which in turn brings in mispricing problems. Besides, ownership structure is found to affect the market based measures where banks with domestic and private ownerships are found to benefit more. However; since no significant distinction could be detected among any of the ownership compositions for accounting based profitability measures, such misappraisals seem to foster the optimism in the market.

Renewable Energy Production, Energy Consumption and Sustainable Economic Growth in Turkey: A VECM Approach
(Mdpi, 2019) Dinc, Dilek Temiz; Akdoğan, Ece Ceylan; Akdogan, Ece C.; Bankacılık ve Finans
There exists a highly interrelated relationship between energy, the environment and growth where the efficient management of this nexus is not only a must for sustainable development and human wellbeing but is also a basis for formulating sound economic policies harnessed with energy and environmental policies. Thus, this paper aims at investigating the causal relationships among renewable energy production, total energy consumption and economic growth for Turkey both in the long and short runs. The analyses are conducted by using the Johansen-Juselius co-integration test, the vector error correction model, Granger causality, impulse-response functions and variance decomposition for the period 1980-2016. Our findings obtained for the causal relationship between renewable energy and economic growth points to a bidirectional relationship both in the short and in long runs that promote feedback hypothesis, and it also reports a causal relationship running from energy consumption to economic growth both in the short and long runs, supporting the growth hypothesis. However, no consistent result could be obtained for the short run relationship from economic growth to energy consumption. These results indicate that increased renewable energy production and decreased energy consumption are vital for Turkey's sustainable development.
