Article Citation - WoS: 7Citation - Scopus: 8Firm Survival in Times of Crisis: Do Innovation and Financing Constraints Matter? Insights From the Covid-19 Pandemic(Routledge Journals, Taylor & Francis Ltd, 2023) Ozsuca, Ekin AyseUtilizing survey data collected over three rounds, this paper investigates the impact of pre-COVID innovation performance, innovation type, sources of knowledge, and the moderating role of financial constraints on survival following the outbreak of COVID-19. The findings pinpoint a strong and positive link between firm survival and innovation, especially process innovation, confirming the ability of innovators to adapt to new conditions as a determinant of survival. Moreover, relying on internal knowledge is found to increase the chance of survival and adaptability to times of crisis. The results further indicate that access to finance strengthens the positive impact of innovation on firm survival/adaptation.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 Stochastic Pattern of Health Care Spending: Evidence From Nonlinear Panel Data Analysis(Better Advances Press, 2021) Yasar, N.This paper analyses the stochastic pattern of health care spending for 188 countries around the world which are categorized into four groups based on the World Bank income categories. 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.

As time went by,\rthe Federal Reserve deemed particularly one sub-component of this data, namely the\rincrements on average weekly wage growth as a proxy for in\ration and thus a plausible\rexplanation for raising the interest rates. In that aspect, we decide to elaborate on this\rissue further and examine whether this implemented strategy indeed had a re\rection in\rthe real market. For doing so, we intend to determine whether there is any causality\rrelation in either direction between US average weekly wage increases and 10-year\rTreasury Bond rates. We utilize the Toda-Yamamoto causality approach and come\rup with a statistically signicant result between wages and bond rates. For robustness,\rwe also consider the unemployment rate and consumption expenditures as independent\rvariables.Book Part Citation - Scopus: 7The Convergence of Electricity Prices for European Union Countries(Springer International Publishing, 2020) Telatar, M.E.; Yaşar, N.The goal of achieving a single European market for electricity has been one of the main objectives for European countries since the “Single European Act” of 1988. The main purpose of this study is to examine whether the aim of unified electricity market has been achieved in terms of the convergence of electricity prices. Β-Convergence and s-convergence tests, are applied for 12 European Union states electricity price data through the period of 2003-2017. For this reason, along with conventional applied techniques, recently improved unit root tests are implemented for both linear and nonlinear data generating processes. The results suggest that convergence did not occur for most of the considered countries. © Springer Nature Switzerland AG 2020.Article Citation - WoS: 10Citation - Scopus: 16The Causal Relationship Between Foreign Debt and Economic Growth: Evidence From Commonwealth Independent States(Sage Publications india Pvt Ltd, 2021) Yasar, NerminThis study investigates the relationship between external borrowing and eco-nomic growth in the Commonwealth Independent States during the period 1995-2018. Autoregressive distributed lag (ARDL) model is employed to determine the co-integration relationship among the series and then vector error correction model (VECM) is used to analyse the causality between external debt and income.The obtained results suggest that there is a negative long-term unidirectional causal relationship running from external debt to GDP presenting a strong evidence of existence of debt overhang hypothesis.The possible reasons for this unidirectional causal relationship can be explained by poor management of provided financial resources and incomplete governance in economic transition process along with structural rigidities and immature institutions in these countries which, in the long term, resulted in insufficient capital charged to service external debt.The policymakers in these post-Soviet countries should not use foreign loans to capitalise the deficits in the economies; instead, they should be more determined in employing these funds in the areas that will create national value-added production and, thus, future income.Article Citation - Scopus: 1Stationarity Properties of Renewable Energy Consumption in the Commonwealth of Independent States(Econjournals, 2020) Yasar, N.This study investigates the stochastic properties of renewable energy consumption series across 11 Commonwealth of Independent States countries through the period of 1990-2015. For this purpose, along with traditional stationarity analysis recently improved unit root techniques which allows for nonlinear adjustments in the data generating process are used in this paper. Based on our findings we may conclude that, consideration of nonlinearity in regression process causes to more frequent non rejection of the null hypothesis of stationarity. It implies that ignoring possible nonlinearities in time series regression process may lead to some misleading results. Hereby, fluctuations in global energy supply and trade systems influence renewable energy consumption in nonlinear pattern and policy-makers should take it into consideration in terms of proper energy policy implication. © 2019, Econjournals.
