Article Citation - Scopus: 28The Relationship Between Energy Consumption and Economic Growth: Evidence From Different Income Country Groups(Econjournals, 2017) Yaşar, N.This study analyses the relationship between energy consumption and economic growth for 119 countries during the period of 1970-2015, classified into four groups regarding to the World Bank income ranking. The main motivation of this study is to analyze whether the causal relationship differs between different income groups of countries. For this purpose, panel auto regressive distributed lag boundary approach and Granger causality test were used. The results of the study indicate that the causal relationship between energy use and economic growth differs depending on which income group country belongs to. We conclude that the feedback hypothesis is supported for upper-middle income group in the long run and high-income group, while conservation hypothesis is supported for upper-middle income group in the short run and lower-middle income group in the long run. Finally, neutrality hypothesis is supported for low and lower middle-income groups in the short run. © 2017, Econjournals.

Elde edile sonuçlara göre, Türkiye’de banka sermaye tamponları iş çevrimlerine karşı döngüsel hareket etmektedir.Ancak bu bulgu yatırım ve kalkınma bankaları için geçerli değildir. Diğer yandan, bankalara özgü özelliklerle ilgili panel regresyon sonuçlarına göre, büyüklük, karlılık ve risk ticari bankaların sermaye tamponlarının anlamlı belirleyicileri olarak ortayaçıkmaktadır. Aynı zamanda, bankacılık sektörünün yapısı ve 2008 küresel finansal krizinin banka sermaye tamponları üzerinde etkili olduğu gözlenmiştir. Sermaye tamponlarının bankaların kredi arzı üzerindeki etkisine dair bulgular ise ters yönlü bir ilişkiye işaret etmektedir. Çalışmanın bulguları, banka sermaye yeterliliğine ilişkin düzenlemeler ile Basel III uzlaşısı kapsamında önerilen ve yakın zamanda uygulamaya koyulan döngüsel sermaye tamponuna dair sonuçları bakımından önem taşımaktadırArticle The Stochastic Futures of the Natural Gas Prices: Russian Federation in Caspian Region(2014) Yaşar Başkaraağaç, NerminThis study examines the convergence hypothesis of natural gas price series of Russian Federation and USA using both linear and nonlinear time series techniques Russian Federation and USA during the period of 1991-2011. Although the linear Augmented Dickey Fuller (ADF), Philips Perron (PP), test provide evidence of the existence of a unit root, which means that the series are nonstationary, KPSS test result support the null hypothesis of existence of the stationary series. A nonlinear test as an alternative approach to investigate whether there are nonlinearities in the series is also taken into consideration. KSS, the nonlinear testing procedure provide some supportive evidence of a nonlinear price convergence among the Russian Federation and USA.Article Tüketicilerin Demografik Özelliklerinin Marka Tercihleri ve Marka Kişiliği Oluşumu Üzerine Bir Araştırma: Emlak Sektörü Örneği(2022) Özsaçmacı, Bülent; Dursun, TolgaPazarlama literatüründe marka kişiliği kavramı araştırmalara konu olmaya başladığı dönemden bu yana pek çok kategoride yer alan markaya yüklenen kişilik özellikleri çeşitli karşılaştırmalara konu olmuştur. Bir tüketicinin almak istediği ürünü veya hizmeti seçerken, kendi kimliği ile özleştirmiş olanı tercih edeceği yapılan araştırmalarda ortaya çıkan bir gerçektir. Bu gerçek, pazarlama sürecinde \"marka kişiliği\" kavramının önemini bir kat daha artırmaktadır. Bu çalışmada, hizmet sektöründe yer alan beş kurumsal gayrimenkul danışmanlık şirketinin sahip oldukları marka kişilik özelliklerinden hangilerinin tüketiciler tarafından ön planda tutulduğu araştırılmıştır. Bu araştırmanın uygulama kısmında bir anket çalışması düzenlenmiş ve anket sonucunda elde edilen bulgulara göre, katılımcıların tercih ettikleri kurumsal firmalarla cinsiyete ve yaşa bağlı olarak anlamlı bir ilişkiye rastlanmazken; meslek, eğitim durumu ve gelir düzeyleri ile anlamlı bir ilişkiye sahip olduğu anlaşılmıştır. Ayrıca araştırma kapsamında ilgili firmaların marka kişiliği boyutlarından hangileriyle eşleştiği de ortaya konmuştur.Article Ethical İssues İn Marketing: An Application For Understanding Ethical Decision Making(2014) Parıltı, Nurettin; Külter Demirgüneş, Banu; Özsaçmacı, BülentIn recent years business ethics and social responsibility have gained great importance in marketing practices, especially in societal marketing practices. Businesses infinitely struggle to indicate their contributions to society. Consumers consciously evaluate this contribution. Manipulated consumer choices and unethical marketing applications can affect purchasing behavior. Particularly intense competition, globalization and societal consciousness transform businesses into social organizations and lead them into marketing efforts offering social value. Although business ethics and social responsibility of businesses have gained more attention in recent years, defining consumers’ perceptions on ethical issues is still minimal. This study presents an empirical research of consumer perceptions on ethical issues. Reflection of this perception on purchasing behavior is also another important issue to be considered. The aim of this study is to investigate the factors related with ethical issues in marketing practices and to reveal possible influences of these factors on consumers’ ethical decision making. The main objective of the study is to find out consumers’ perceptions on businesses’ ethical issues such as misleading advertising, deceptive packaging and to reveal the impact of these issues on their ethical purchasing behavior or ethical decision making.

The main motivation of this ar-ticle is to evaluate whether the stochastic features of total health care expenditure varies if decomposed into private and public health care consumption. To achieve this goal, in addition to conventional empirical methods, latterly de-veloped panel stationarity approaches are employed for both linear and nonlinear regression processes. Our results demonstrate that allowing for cross-section dependency between series and nonlinearity in the estimation process may lead to more often rejection of the null hypothesis of unit root for all series in panel data set. © 2021 Better Advances Press.

The estimation results indicate that margins behavecountercyclically during economic fluctuations. It appears that Turkish banks’ price-costmargins tend to stay high acting countercyclical during economic downturns, which maylimit the supply of loans and thereby, cause a further reduction in production, deepeningthe contraction. Specifically, several bank-specific characteristics, that is; banks’liquidity, capitalization and size, together with the monetary policy and marketconcentration in the banking industry are found to be crucial in explaining thecountercyclical behavior of net interest margins in Turkey. Furthermore, the recentglobal financial crisis in the late 2008 seems to have a considerable effect on the banksmargins as well. Overall, these findings provide evidence for the existence of “financialaccelerator” at work in the Turkish economy during the period under investigation.Article Insights into Consumer Preference of Foreign Brand Names: Reality or Myth?(2014) Akagün Ergin, Elif; Özsaçmacı, BülentThis study builds from LeClerc et al.’s (1989, 1994) work on foreign branding effects, but it does so in the context of a developing East European country; as in the case of Turkey.
