Determination of Women Voting Behavior: a Machine Learning Approach in the Turkish Political Arena
(Hipatia Editorial, 2020) Çaha, H.; Bayyurt, N.
Justice and Development Party (AKP) has been the ruling and biggest party in Turkey (AKP) since it has been established in 2002 and Republican People’s Party (CHP) has been the main opposition party (CHP) since then. These two parties receive about 75% of all the votes. In Turkey half of the voters are females. In this study, the important attributes of women in party selection decisions are analyzed. To our knowledge, there is no such a study focusing on women’s party preferences in Turkey. Additionally, this is one of the very few studies in Turkey concerning voters’ party preferences. Therefore, this study aims to fill this gap in the literature. Center-periphery and social mobility theories are the two main theories explaining Turkish political life. The analyzed ideological, cultural, religious, social, economic and demographic characteristics of women supporters are selected according to these theories. Machine-learning techniques are employed as predictive tools. Results show that ideological attitudes like being leftist-rightist and religious values like headscarf, fasting in Ramadan, and praying are the most important effective attributes on party selection of women. However, socio-economic, cultural, educational and demographic atributes are not effective on party selection of women in Turkey. © 2020, Hipatia Editorial. All rights reserved.
Effect of Economic Policy Uncertainty on Co2 With the Discrimination of Renewable and Non Renewable Energy Consumption
(Pergamon-elsevier Science Ltd, 2024) Atay Polat, Melike; Ilhan, Ozturk; Usama, Al-Mulali; Savranlar, Buket; Polat, Melike Atay; Metawa, Noura; Raboshuk, Alina
The link between policy -related economic uncertainty and the environment has a new and developing literature. In this study, the effects of economic policy uncertainty, energy consumption and economic growth on pollution in G7 countries are investigated by using methods of moments quantile regression over the perod of 1995-2018. According to the long run coefficient estimation results, in the model in which the fossil fuel energy consumption variable is used as an energy consumption indicator, economic policy uncertainty has a reducing effect on emissions at all quantile levels. Although this negative effect becomes more pronounced as the quantile level increases, it is statistically insignificant at the 0.90 quantile level. In the model that includes fossil fuel energy consumption, the coefficient of economic policy uncertainty variable is negative in all quantiles and is significant only at the 0.30 and 0.40 quantile levels. In addition, while a U-shaped relationship is detected between economic growth and emissions in these countries, the destroying effect of fossil fuel energy on environmental quality is confirmed in all quantiles. Thus, it should be a priority to support the developments in growth performance with environmental regulations, encourage energy -saving and energy -efficient practices as well as to establish the legal infrastructure.
Evaluation Of The Relationship Between Foreign Trade Liberalization And Unemployment Within The Framework Of The Heterogeneous Firm Model;
(Sosyoekonomi Society, 2022) Çirkin, Z.; Göksel, T.
This study investigates how foreign trade liberalization affects unemployment by using the Melitz model (2003), which is one of the intra-industry trade models expressing trade between countries with similar technologies, preferences, and cost structures that make up a large part of international trade. The Melitz model (2003) is remodelled by efficiency wage theory to endogenize unemployment. The model is solved by numerical method. It is assumed that market expansion and competition in the market occur simultaneously. The effect of liberalization on unemployment varies depending on which of two factors, market expansion or competition, dominates the other. According to the results, unemployment decreases when market expansion dominates the competition, while unemployment increases if competition dominates market expansion. In addition, it has been observed that there is an increase in the total amount of production, productivity, and unemployment insurance when market expansion is dominant. Also, it has been observed that there is a decrease in the total amount of production, productivity level, and unemployment insurance when competition in the market is dominant. © 2022, Sosyoekonomi Society.

Evidence From Turkish and Syrian People for the Measurement Invariance of the Cbbe Scale and Clues for the Distribution Strategies of the Brands
(Kodisa Foundation, 2023) Kayaoğlu, Ahmet; Gülmez, Yavuz Selim; Kayaoglu, Ahmet; Gulmez, Yavuz Selim
Purpose: This research aims to test the measurement invariance of the consumer-based brand equity scale on Turkish and Syrian university students who live together but are from different cultural groups. Research design, data, and methodology: The consumer- based brand equity scale developed by Buil et al. (2008) is applied to the participants. In testing the consumer-based brand equity scale, the Netflix brand, which is considered well-known by both cultural groups, is preferred. It is thought that choosing an internationally recognized brand would facilitate the conduct of this research. Structural invariance and measurement invariance are tested using structural equation modeling. Results: The consumer-based brand equity scale has measurement invariance on Turkish and Syrian university students. Therefore, it has been revealed that the responses of participants from both cultures regarding the Netflix brand are comparable. Conclusion: The findings of the study provide clues for practitioners to review their distribution strategies. As a matter of fact, cultural studies conducted in different countries are common. Still, the originality of this study is ensured by the profile of participants who live in the same country but come from different countries.
Misspecified expectations in an open economy
(Elsevier, 2024) Yılmaz, Yusuf Ömür; Cicekci, Cumhur
In the past two decades, Turkey has experienced multiple changes in its monetary policy regime.To analyse how these policy changes affect the behaviours of households and firms, somebehavioural parameters are incorporated into a small open economy New Keynesian model. Ourapproach consists of four phases. First, we assess the impacts of the behavioural parameters onthe model and find that higher values of the parameters increase the effects of expectationson the model. Second, for the period between 2006 and 2021, the model is estimated for theTurkish economy and the findings show that both households and firms are more forward-looking in their decision making. Moreover, the current variables have a weak effect on thenominal interest rate, and the inertial nominal interest rate has a strong effect on it. Third, weanalyse the evolution of the model parameters over the period and find that the behaviouralparameters tend to increase, while the monetary policy becomes more inertial. Finally, weconclude that the Central Bank should follow Domestic Inflation-based Taylor rule to minimise welfare loss
Negotiation, Speed, Politics: Use of Digital Technologies in International Mediation
(İstanbul Üniversitesi, 2024) Burç, Safiye Ateş
Yeni dünya düzeninin (covid ve post-covid dönemler) süper hızlandırılmış (yüksek hızlı) yaşam deneyimleri ve zorlayıcı uygulamaları, uluslararası aktörlerin müzakere ve çatışma çözme becerilerini de etkilemiş ve değiştirmiştir. Günümüzde pandemi ve teknolojik gelişmelerle birlikte hızlanma birçok alanda zorunluluk haline gelmiştir. Başta Birleşmiş Milletler (BM) olmak üzere birçok uluslararası arabulucu da Covid-19 pandemisinde mekanı ve zamanı delen dijital teknolojilerden büyük ölçüde yararlandı. Peki ekonomik, sosyal ve teknolojik gelişimin yüksek hızda devam ettiği günümüz dünyasında müzakereler ve politikalar da bu hıza eşlik etmeli mi? Eğer öyleyse, hızlandırılmış ve sanallaştırılmış siyasi pratikler çatışma çözümünde nasıl ele alınmalıdır? Dijitalleşmenin uluslararası arabuluculuk üzerindeki etkisi nedir? Bu sorular etrafında şekillenecek olan bu makalede, dijitalleşme, hız(lanma), siyaset ve çatışma çözümü arasındaki ilişki, özellikle pandeminin en travmatik döneminde (Mart 2020-Mart 2021) farklı BM misyonlarının barış yapım pratiklerine ilişkin siyasi raporlarının içerik ve söylem analizi yardımıyla eleştirel bir şekilde tartışılmaktadır. Bu çalışmada siyaset ve müzakere, zamana ihtiyaç duyduğu için hız bariyerlerine sahip olması gerektiği ama yüksek hızlı toplumun gelişmelerinden ve alanından da soyutlanamayacağı için sanal alanı her an takip edip ihtiyaç duyulduğu anda dahil olması gerektiği sonucuna varılmıştır. Misyonların rapor analizlerinin de gösterdiği üzere özellikle pandemide dijital teknolojilerin etkin kullanımı arabuluculukta hızlı bir dönüşüme (gelenekselden siber-arabuluculuğa) yol açmış ve çatışma çözümü faaliyetleri kesintisiz bir şekilde sürdürülebilmişse de dijitalleşmenin tehlikeleri ortadan kalkmış değildir.
A New Approach for the Fractional Integral Operator in Time Scales With Variable Exponent Lebesgue Spaces
(Mdpi, 2021) Akın, Lütfi
Integral equations and inequalities have an important place in time scales and harmonic analysis. The norm of integral operators is one of the important study topics in harmonic analysis. Using the norms in different variable exponent spaces, the boundedness or compactness of the integral operators are examined. However, the norm of integral operators on time scales has been a matter of curiosity to us. In this study, we prove the equivalence of the norm of the restricted centered fractional maximal diamond-alpha integral operator M-a,delta(c) to the norm of the centered fractional maximal diamond-alpha integral operator M-a(c) on time scales with variable exponent Lebesgue spaces. This study will lead to the study of problems such as the boundedness and compactness of integral operators on time scales.
On the Fractional Maximal Delta Integral Type Inequalities on Time Scales
(MDPI AG, 2020) Akın, L.; Akın, Lütfi
Time scales have been the target of work of many mathematicians for more than a quarter century. Some of these studies are of inequalities and dynamic integrals. Inequalities and fractional maximal integrals have an important place in these studies. For example, inequalities and integrals contributed to the solution of many problems in various branches of science. In this paper, we will use fractional maximal integrals to establish integral inequalities on time scales. Moreover, our findings show that inequality is valid for discrete and continuous conditions. © 2020 by the author. Licensee MDPI, Basel, Switzerland.
Orta Doğu Güvenlik Mimarisinde Yaşanan Değişimin İsrail Siyasetine Etkileri
(2023) Acar, Necmettin; Acar, Necmettin
İsrail, 2020 sonrası dönemde içeride Filistinlilere karşı baskıyı artıran, dışarıda ise komşu Arap devletlerine karşı yoğunlaşan saldırgan bir politikaya yönelmiştir. İsrail iç ve dış politikasında yaşanan bu değişim önemli ölçüde 2000 sonrası dönemde Orta Doğu güvenlik mimarisinin yaşadığı dönüşümün bir sonucudur. 2003 yılındaki ABD işgali ile başlayıp 2010 yılındaki Arap Baharı ile devam eden süreç Irak, Mısır ve Suriye gibi bölgesel aktörlerin zayıflayarak bölgesel siyasetteki ağırlıklarını kaybetmesiyle sonuçlanmıştır. Arap Baharı sürecinde Filistin meselesine kitlesel destek ve kamuoyu ilgisi uyandıran Reformcu İslamcılık düşüncesinin zayıflaması da Arap kamuoyu nezdinde Filistin meselesine olan ilgide bir azalma ortaya çıkarmıştır. Irak, Suriye ve Mısır gibi güçlü bölgesel aktörlerin zayıfladığı, Reformcu İslamcılık düşüncesinin itibar kaybettiği bir dönemde ekonomik olarak güçlü olsalar da askeri açıdan zayıf olan Körfez ülkelerinin Filistin meselesinde liderliğe soyunmaları İsrail’in elini güçlendirmiştir. Bölgede İsrail’i sınırlama/dengeleme kabiliyetine sahip aktörlerin pozisyonlarında yaşanan zayıflama İsrail’i iddialı ve revizyonist politikalar konusunda cesaretlendirmiştir.
Testing for Aggregate Instability in an Open Economy
(Bogazici Universitesi, 2022) Yılmaz, Y.Ö.; Yılmaz, Yusuf Ömür
This paper empirically tests the Turkish economy’s stability between 2010 and 2016 using a small open economy New-Keynesian model featuring a positive long-run inflation rate and sunspot shock under alternative monetary policy rules. We found that the probabilities of indeterminacy are very close to unity. We can thus conclude that the economy is unstable over this period primarily because the long-run inflation rate is in the higher single digits despite the Central Bank’s weak response to inflation. This drove the economy into aggregate instability. © 2022 Bogazici Universitesi. All rights reserved.
Türkiye İle Türk Cumhuriyetleri Arasındaki Ekonomik İlişkiler: Dış Ticaret, Turizm ve Yatırım Açısından Bir Değerlendirme
(Bingöl Üniversitesi Sosyal Bilimler Enstitüsü Dergisi, 2019) Doru, Ömer; Aslan, Mehmet Barış; Doru, Omer
Bu çalışmada Türkiye ile Türk Cumhuriyetleri arasındaki ekonomik ilişkilerdış ticaret, doğrudan yabancı yatırımlar ve turizm bağlamında değerlendirilmiştir.Türkiye ile olan tarihsel bağın yanında son dönemlerde doğal kaynakların pazarlanmasından doğan gelir artışları bölgenin Türkiye için önemli bir dış ticaretpotansiyeli olduğunu göstermektedir. Bundan yola çıkarak hazırlanan çalışmada;Türkiye’nin bu ülkelerin dış ticaretlerindeki rolü, yapmış olduğu doğrudan yabancıyatırımlar ve karşılıklı gelen turist sayıları tarihsel süreç içerisinde düzenlenerek,ülke gurubu ile Türkiye arasındaki ekonomik ilişki ortaya konulmuştur. Bunun yanında Türk Cumhuriyetlerinin ekonomik faaliyet guruplarına göre yapmış olduklarıihracat ve ithalat miktarlarında Türkiye’nin payı ortaya konularak sektör bazındamevcut durum belirlenmiştir. Sonuç olarak Türkiye ile Türk Cumhuriyetleri arasındaki ekonomik ilişkilerin son dönemlerde artmasına rağmen istenilen seviyeyeulaşmadığı görülmüştür.
