The Effects of Oil Price Shocks on Clean Energy and Oil and Gas Stock Returns

UÇKUN ÖZKAN, Ayşegül

This study empirically examines how fluctuations in oil prices affect the stock returns of clean energy and oil and gas companies between 2001:01 and 2022:06. Our results show that a negative oil supply shock affects the stock returns of clean energy companies positively. In contrast, an oil-specific demand shock negatively affects them. The findings also reveal that an increase in oil prices owing to an oil-specific demand shock tends not to improve the stock returns of oil and gas companies. Consequently, the results indicate that oil and clean energy are not alternatives.

The impact of investor attention on green bond returns: How do market uncertainties and investment performances of clean energy and oil and gas markets affect the connectedness between investor attention and green bond?

UÇKUN ÖZKAN, Ayşegül

This paper empirically investigates the spillover between investor attention and green bond returns by utilizing the connectedness approach. We will examine the impact of uncertainty in the stock, bond, and energy markets, as well as the success of clean energy, oil, and gas investments, on the relationship between green bonds and investor attention. We find that there are positive but small spillovers between investor attention and green bond returns. Besides, the connectedness between investor attention and green bond market performance is stronger in the short run than in the long run. Furt ...Daha fazlası

The Energy Cost Comparison Using Mixed Integer Linear Programming and Simulated Annealing Method in Smart Home

GÜLER, Emre | BAŞARAN FİLİK, Ümmühan

Smart home energy scheduling problem is a significant subject in power system to avoid extra expenditure. In this work, the scheduling problem is realized using mixed integer linear (MILP) programming and simulated annealing (SA) method. MILP is one of the integer optimization method and SA is a strong technique for solving hard combinatorial optimization problems. Various types of electricity tariff is applied from country to country. In Turkey, one term and three term tariffs (electricity prices are divided into three parts; off-peak hours, mid-peak hours on-peak hours) are used. In this stu ...Daha fazlası

Comparison of decision-making approaches to prioritization of clean air action plans for sustainable development

ÇALIK, Ahmet

Background: Clean air action plans have been prepared and are still being implemented in Turkey to control and prevent air pollution, and improve the air quality. The plans reveal a picture of the current situation and available inventory information. However, in order to implement the identified plans in real life, they need to be prioritized. This study aimed to identify and prioritize clean air action plans for Turkey using a framework of both fuzzy and crisp evaluations. Methods: In this study, priorities of the plans were identified and analyzed with a decision-making model. A three-step ...Daha fazlası

Line × tester analysis of stomatal conductance, chlorophyll content, photosynthetic efficiency, and transpiration rate traits in maize

ÖZDEMİR, Elif | SADE, Bayram

This study evaluated seven inbred lines of maize (Zea mays L.), three testers and 21 hybrids produced by line × tester mating design. Stomatal conductance, chlorophyll content, photosynthetic efficiency, and transpiration rate traits of parents and progenies were observed. The study was conducted in Konya, in the mid-Anatolian region of Turkey. The mean values of the stomatal conductance, chlorophyll content, photosynthetic efficiency, and transpiration rate measurements were evaluated using Duncan’s multiple range test for grouping parent and offspring groups. The variance for general combini ...Daha fazlası

Multidimensions of poverty for agricultural community in turkey: Konya province case

KAN, Mustafa | OĞUZ, Cennet | KAN, Arzu | ERGUN, Hüseyin | DEMİRÖZ, Emel

Poverty is a multi-dimensional global phenomenon. It encompasses health, housing, education, and social exclusion as well as simple incomes and expenditures. Multidimensional poverty is currently at the heart of many theoretical, empirical and institutional debates. The study was carried out in a rural settlement of Konya province in Turkey to determine the rural population’s poverty structure and to quantify different general characteristics of both the poor and non-poor population according to the poverty line (relative poverty based household income-monetary approach) and asset based wealth ...Daha fazlası

Industry 4.0 and Turkey

YAŞAR, Esra | ULUSOY, Tuba

In 2011, Germany kicked off the Fourth Industrial Revolution (Industry 4.0) to empower its economy. Since then, revolutionary changes have been implemented all over the world, increasing international competition. Smart-factory capabilities emerging fromIndustry 4.0 have many benefits such as lowering production costs of existing factories and increasing product quality. However, with such revolutionary changes, an orientation period is required for any implementer. To efficiently manage such an orientation period, the extant situation must first be analyzed. Only then should the necessary cha ...Daha fazlası

Multi-level optimization of an automotive closed-loop supply chain network with interactive fuzzy programming approaches

YILDIZBAŞI, Abdullah | ÇALIK, Ahmet | PAKSOY, Turan | ZANJİRANİ FARAHANİ, Reza | WEBER, Gerhard Wilhelm

Closed-Loop Supply Chain (CLSC) management has attained appreciable attention over the last few years. CLSC management allows companies to manage their recovery and recycling activities of end products. Due to the latest developments in the world, producers are responsible for the collection, refurbishing, repairing and disassembly of end products at the end of their lives. This paper develops a mixed-integer CLSC model that is inspired by the automotive industry. In this model, we consider three Decision Makers (DM): Plant, Dismantler Center and Customer. Each DM has individual objectives and ...Daha fazlası

Modeling comorbidity of chronic diseases using coupled hidden Markov model with bivariate discrete copula

OFLAZ, Zarina | YOZGATLIGİL, Ceylan | KESTEL, Sevtap

A range of chronic diseases have a significant influence on each other and share common risk factors. Comorbidity, which shows the existence of two or more diseases interacting or triggering each other, is an important measure for actuarial valuations. The main proposal of the study is to model parallel interacting processes describing two or more chronic diseases by a combination of hidden Markov theory and copula function. This study introduces a coupled hidden Markov model with the bivariate discrete copula function in the hidden process. To estimate the parameters of the model and deal wit ...Daha fazlası
