    Economic Consequences of Daylight-Saving Time: Evidence from Turkey
    (Gümüşhane Üniversitesi, 2019) Akarsu, Gülsüm; GÜMÜŞOĞLU, NEBİLE KORUCU
    For last years, it has been hot issue that transition to daylight saving time has some important consequences related to the electricity consumption, human health, performance, behavior and well-being of individuals. Since the cabinet decision in 2016, Turkey has been implementing the summertime throughout the whole year in order to save energy. Therefore, the main aim of this study is to analyze the effects of this change on economic growth and labor productivity by employing quarterly data for the time period 2006:Q1 and 2018:Q1 for Turkey and Threshold AR model in order to incorporate the nonlinear behavior in considered time series. The results show significant effect of this policy change as well as nonlinear behavior in the time series due to continuous fluctuations in the data throughout time which can be classified into at least two regimes as recession and expansion. As a conclusion, the countries should evaluate the effects of daylight saving time (DST) on different indicators before any change in the implementation.

    Economic Growth: Is it Green or not? An Application on OECD
    (2021) Akarsu, Gülsüm; GÜMÜŞOĞLU, NEBİLE KORUCU; 53145; 115505
    For climate change mitigation and considering other environmental impacts of traditional energy sources, countries have started to implement energy policies in favor of renewable energy sources. In this way, without any detrimental effect on economic growth, countries can decrease their fossil fuel consumption. However, there is a debate about the direction of causality between renewable energy consumption and economic growth as for the total energy-growth nexus. Moreover, in the literature, the studies focus only on the total or specific type of renewable energy consumption while analyzing the direction of causality. From this point of view, there is a gap in the literature in such a way that there is a need for a comprehensive analysis which compares the existence and direction of causality for different types of renewable energy sources and technologies. Therefore, the main aim of this study is to investigate renewable energy consumption and growth nexus. By using panel data on renewable electricity generation for OECD countries over the years from 2000 to 2016, the causality is tested for different technologies. Moreover, as the economic growth may not correctly measure the overall economic well-being, another measure for welfare is used. Therefore, the main motivation of this study is to include welfare in renewable energy and growth nexus in which different type of technologies for renewable energy are considered. The results for both economic growth and welfare measure show that the existence and directi highly differs among the different technologies. Therefore, technology specific policies should be implemented in order to stimulate the renewable energy investments and consumption.
