Training programs for university presidents mission indispensable
(IISTE, 2014) Teker, Suat; Atan, Tarık
The evaluation and selection process of presidents/rectors of universities and other higher educational institutions has always been a very special, extraordinary, exclusive and usually confidential process regardless of which office and/or authority conducts the process. The main qualification has almost always been the academic accomplishments of the candidates and the most promising place to look for a person with the capacity for the job is within academia itself. But the tasks and challenges facing the elected or appointed presidents are greatly administrative necessitating strategy deliberation; institutional positioning, financial dexterity, social skills, fund-raising capacity and leadership. This shift of overlap presents an unexpected and compelling issues both from the perspective of the candidate (or appointee) and institution. Addressing these issues is never easy and institutional pressures do not permit the luxury of learning on the job. Consequently, new educational schemes become available aimed directly the new elected or appointed position owners. This study investigates the training programs for elected and/or appointed president/ rectors as well as aiming the potential candidates. Some training programs are examined and compared by their perspectives, approach, duration, and content. And a new approach for training presidents of the educational institutions discussed.
5G technology and future of banking
(The Brooklyn Research and Publishing Institute, 2021-12) Teker, Suat; Teker, Dilek; Orman, Irmak
This study examines the effects ofdevelopments in communication technologies on the banking sector and banking services. In addition, it is envisioned how 5G technology will shape the future of the banking industry. As a result of the analysis, it has been observed that an important innovation and structural transformation period was lived in the banking sector with the use of 3G and before 2000, which we define as traditional banking era. It is concluded that with the expected wide use of 5G technology after year 2022, the banking sector is expected to enter a new and disruptive restructuring and service innovation.
Estimation of Bitcoin volatility: GARCH implementation
(Seventh Sense Research Group, 2020-01) Teker, Dilek; Teker, Suat
As bitcoin has been a topic of high interest for academic and professional life over recent years, a number of literature has examined its price movements, volatility, and predictions. Bitcoin is the first and perhaps the most popular cryptocurrency with a high volatility pattern compared to the other cryptocurrencies. This paper examines the models that explain the volatility of Bitcoin prices. The daily data for the Bitcoin prices are used through a period of July 31, 2017, to April 3, 2019, with a total number of observations of 484. Initially, unit root tests are implemented. Then, the heteroskedasticity problem is tested among variables. Based on the results of the heteroskedasticity test, it is decided to use ARCH models. Then, ARCH, GARCH, TGARCH, and EGARCH results are tested to find out the best fit model that explains the bitcoin price movements.
Income inequality in Central and Eastern European countries
(Fenerbahçe Üniversitesi, 2022-12-31) Görkey, Selda
Central and Eastern European (CEE) economies share a common past since they passed through a transition period in the 1990s. They experienced rapid economic growth in the post-transition period by facing structural changes in their economies and institutions. Even though achieving economic growth is desirable, it is not sufficient alone; rather, it is expected to be supported by more even income distribution. Accordingly, income inequality becomes a crucial topic in economic growth and development, particularly for CEE countries. This study examines income inequality in 12 CEE economies using a descriptive research method. The study reaches diversified outcomes by using various indicators on the topic, such as the poverty headcount ratio, the at-risk-of-poverty rate, the Gini coefficient, and income quintiles and deciles-related measures. The overall findings clearly show that income inequality is a critical concern in the region. Income inequality is the highest in Bulgaria, Romania, and Albania, and these economies are followed by Latvia and Lithuania, according to most of the indicators utilized. Forming an exceptional group; Czechia, Slovenia, and the Slovak Republic have more even income distribution not only compared to the other CEE economies but also the EU27. These economies are followed by Estonia and Hungary according to the outcomes reached by this study. The findings of this study can be used for policy designs to decrease the extent of income inequality in CEE economies.
The comparative development of ICT in BRICS a cluster analysis
(İbrahim Güran Yumuşak, 2016) Görkey, Selda; Yalkı Berker, İrem
The development of Information Communication Technology (ICT) has been one of the main drivers of technological change and, hence, of economic growth in recent years. Brazil, Russia, India, China and South Africa, the so-called BRICS countries, are well known for their technological potential and they have therefore inspired many studies that examined their economies from various perspectives. However, only a few have specifically focused on ICT in BRICS. This study aims to contribute to the literature by determining the comparative development of ICT in each BRICS country relative to 200 countries during the period from 2005 to 2013. For that purpose, cluster analysis is used as a methodology. The clusters are defined by: fixedbroadband subscriptions, fixed-telephone subscriptions, mobile-cellular-telephone subscriptions, and percentage of individuals using the internet. There are five clusters: very-low, low, medium, high and very-high. Each corresponds to a comparative development level. The empirical findings indicate that, among 200 economies in 2005, Brazil, China and South Africa were clustered in the low development group, whereas India belonged in the very-low development cluster and Russia was included in the medium development cluster. Brazil, South Africa and Russia exhibited consistent comparative development during the examined period and, therefore, they are found to be in higher clusters in 2013. The findings also show that the comparative development of ICT in China has been volatile, whereas India’s cluster has varied from low to very-low development relative to the examined economies.
Renewable electricity consumption and economic growth: a cross-income panel ARDL analysis with implications for energy transition
(İstanbul Okan Üniversitesi, 2025-06-02) Brown, Mustapha Abekah; Taşbaşı, Aslı
The transition to renewable energy and the corresponding use of electricity generated from renewable sources is an inevitable solution that must be adopted to mitigate the effects of the climate crisis. The extant literature on the energy-economic growth nexus present mixed findings – some studies suggest the existence of a relationship while others find no significant relationship. Nevertheless, a growing number of recent studies provide evidence of an existing relationship. This study employs the panel ARDL techniques PMG, MG and DFE to investigate the short-run and long-run dynamics between renewable electricty consumption (RELC) and economic growth over the period 2000-2022 across 48 countries classified by income level. The results clearly indicate that the use of green electricity has a positive effect on economic growth across all income levels, albeit with varying magnitudes. Findings of the study provide particularly encouraging empirical evidence for a green transition in developing countries, underscoring the need for more attention to the unique challenges and opportunities faced by these economies.
Causal links between patents and economic growth: empirical evidence from OECD countries
(Universidade Nove de Julho-UNINOVE, 2024-08) Özkan Yıldız, Öznur; Görkey, Selda
Objective of the Study: This paper empirically investigates the reciprocal relationship and causality between patents and economic growth. Methodology/Approach: Utilizing the Generalized Method of Moments (GMM) Panel Vector Autoregression (PVAR) and panel VAR-Granger Causality frameworks, the study concentrates on Organisation for Economic Co-operation and Development (OECD) economies where a high fraction of global innovative activities take place. Originality/Relevance: The relationship and causality between patents and economic growth are investigated and evaluated by distinguishing the former variable into patent applications and grants. Main Results: The findings from the GMM panel VAR approach indicate that patent applications and grants significantly affect economic growth, whereas economic activities do not influence patent-related variables. The estimations from the panel VAR-Granger approach confirm these findings by presenting a unidirectional causality from patent applications and grants to economic growth. The impulse-response functions (IRFs) exhibit parallel findings, and further checks validate the stability of the findings obtained. The outcomes of this study point out two crucial implications. First, the impacts of patent applications and grants affect economic growth similarly while the impact of patent grants lasts longer. Second, while patents cause higher economic activity, the latter does not induce innovative activity through patents in the OECD. Theoretical/Methodological Contributions: It would be useful to conduct separate analyses for a selected product, sector, or country by including research and development (R&D) expenditures for different periods, country groups, and analysis methods. Social/Management Contributions: Countries should prioritize the establishment of an effective patent management system that will increase the pace of innovation and the implementation of incentive policies for the development of high-value-added technology products.
Yapay zekâ ve yükseköğrenimin dönüşümü
(Işık Üniversitesi Yayınları, 2025-04-30) Koloğlugil, Serhat; Koloğlugil, Serhat
Bu çalışma, yapay zekâ (YZ) teknolojilerinin yükseköğrenim kurumları üzerindeki etkilerini tarihsel, sosyo-teknolojik ve pedagojik bir perspektifle ele almaktadır. Makalede, endüstriyel toplumun ihtiyaçlarına göre şekillenmiş mevcut üniversite yapısının, üretken YZ teknolojilerinin ortaya çıkardığı yeni dinamikler karşısında yetersiz kaldığı savunulmaktadır. ALM hipotezine atıfla, yalnızca rutin bilişsel işlerin değil, aynı zamanda yaratıcı ve üst-bilişsel görevlerin de YZ sistemleri tarafından ikame edilmeye başlandığı vurgulanmaktadır. Bu bağlamda, üniversitelerin yalnızca öğrencilerini bilgiyle donatmakla kalmayıp; onların yaratıcı, eleştirel düşünebilen ve muhakeme yapabilen bireyler olarak yetişmesini destekleyen yeni bir eğitim paradigmasına ihtiyaç duyduğu ileri sürülmektedir. Çalışmada, üç temel dönüşüm alanı öne çıkarılmaktadır: öğrencilerin üst-bilişsel yetkinliklerini geliştiren tematik ve bağlama dayalı öğrenme modelleri; YZ araçlarının bireyselleştirilmiş öğrenme süreçlerine entegrasyonu; ve üniversitenin bir platform olarak yeniden kurgulanması. Sonuç olarak çalışmada YZ çağında üniversitelerin hem kendi organizasyonel yapıları hem de pedagojik yaklaşımları açısından köklü bir dönüşüm geçirmeleri gerektiği ortaya konmaktadır.
İktisadi büyümeyi doğadan ilham alan teknolojiler ile yeniden düşünmek: biyomimikri, yapay zekâ ve döngüsel ekonomi
(Işık Üniversitesi Yayınları, 2025-04-30) Taşbaşı, Aslı
Üretim ve tüketim artışına dayalı anaakım iktisadi büyüme modelleri, küresel ölçekte çevresel tahribatı ve toplumsal eşitsizlikleri derinleştirmiş; piyasa odaklı reçeteler ise bu sorunlara etkili çözümler üretememiştir. Bu çalışma, ekolojik iktisadın kuramsal temellerinden hareketle, biyomimikri ve döngüsel ekonomiyi büyümeyi yeniden tanımlayabilecek dönüştürücü unsurlar olarak ele almakta; gezegenin sınırlarını gözeten, teknolojik ilerleme ve toplumsal refahı önceleyen alternatif bir paradigma önermektedir. Yapay zekânın bu dönüşümdeki belirleyici rolüne dikkat çeken çalışmada, biyomimetik teknolojilerin kısa vadeli kâr maksimizasyonu yerine sürdürülebilirlik ve toplumsal refah ilkeleri doğrultusunda uygulanması gerektiği savunulmaktadır. Bu bağlamda, seçili iktisadi süreçlere ilişkin olarak miselyum ağları ve protoplazmaların yapısal ve işlevsel özelliklerinden esinle, yapay zekâ destekli görsel temsiller geliştirilmiştir. Söz konusu yöntem, hem biyomimetik-analojik eşleştirme yaklaşımıyla, hem de iktisadi sistemlere ilişkin çok katmanlı görsel temsil üretimiyle literatürde özgün bir ilk olma niteliği taşımaktadır.
İktisatta kullanılan dijitalleşme ölçü birimleri üzerine bir değerlendirme
(Işık Üniversitesi Yayınları, 2024-04-30) Görkey, Selda
Bu çalışmada, iktisat disiplininde kullanılan dijitalleşme göstergeleri; oranlar, bileşik göstergeleri temsilen endeksler ve parasal göstergeler olmak üzere üç ölçü birimi çerçevesinde karşılaştırılmakta ve özellikle makro iktisadi ampirik araştırmalar açısından bir değerlendirme yapılmaktadır. Yapılan araştırma, oranların kolay elde edilmelerine yönelik güçlü avantajlarına karşın, çok boyutlu dijitalleşme kavramını ancak kısmen ölçebildiğini göstermektedir. Ayrıca ilgili kavramın dinamik yapısı, oransal göstergelerin sürekli olarak güncellenmesini gerektirmekte, bu durum da uzun zaman boyutlu çalışmalar açısından sorun oluşturmaktadır. Endeksler ise, dijitalleşme ekosisteminin kapsamını daha iyi temsil etseler de alt göstergelerinde oranları içerdiklerinden, oranlar için bahsedilen dezavantajlar endeksler için de geçerli hale gelmektedir. Çalışma ile, iktisat disiplininde dijitalleşmenin parasal göstergelerle daha iyi temsil edildiği sonucuna ulaşılmıştır. Bunda, ilgili göstergelerin, dijitalleşme için yapılan toplulaştırılmış faaliyetleri daha iyi ölçebilmeleri ve uzun dönemli olarak elde edilebilmeleri etkili olmuştur. Dolayısıyla bu çalışmayla, ilgili literatürde, oranların ve endekslerin tek ya da kısa dönemli analizlerde kullanılmasının, parasal göstergelerin ise hem kısa hem de uzun dönemli ülke içi ve ülkeler arası araştırmalarda kullanılmasının uygun olabileceği sonucuna ulaşılmıştır. Varılan bu sonuçlar ile, dijitalleşmenin ölçümü konusuna, veri ile çalışmanın büyük önem taşıdığı iktisat disiplini açısından katkıda bulunulması amaçlanmaktadır.

Knowledge economy and the emergence of less-hierarchical organizational structures: an institutionalist approach
(Işık Üniversitesi Yayınları, 2023-10-25) Koloğlugil, Serhat; Koloğlugil, Serhat
Recent years have witnessed the proliferation of horizontal and less-hierarchical governance structures in organizations. The present paper argues that this development can be read as an institutional transition, within organizations themselves, in response to the rise of knowledge economy. Drawing also upon the related literature on hunter and gatherers, the paper shows that asset-based production is generally related with hierarchical social relations, whereas knowledge-based economic activity tends to generate relatively horizontal and egalitarian structures. It is argued in the paper that a similar dynamic is at work in today’s knowledge-based organizations, and that the institutional approach has the conceptual tools to study this transformation. In this regard, the paper aims to open up a theoretical space where the tools of institutional theory can be used, not only in the study of macro social-structures, but also in that of organizations and their transformations. Some further theoretical and practical implications of this approach are discussed in the final section.
Employment intensity of economic growth in Southern Europe: evidence from multidimensional panel data
(2023-06-26) Görkey, Selda; Şen Taşbaşı, Aslı
This paper examines the employment intensity of economic growth in Southern Europe during the so-called “post-crisis” recovery years. A labor demand estimation model based on multidimensional panel data from 2010 to 2019 was utilized. Findings from our macroeconomic analysis of eight different industries refute the predictions of neoclassical labor theory in the region. The results further indicate the presence of jobless growth in the areas of overall employment, fulltime employment, and overall employees. They also signal that economic growth may have created job opportunities in part-time and youth employment, and among temporary employees, rather than full-time jobs. The paper links these findings to particular characteristics of the regional labor market, discusses their.
Government expenditure and economic growth in Central and Eastern European economies: a panel ARDL approach
(İstanbul Okan Üniversitesi, 2023-03) Görkey, Selda
This study investigates the relationship between government expenditure and economic growth with a primary concern of focusing on the long-run effects. It uses the panel ARDL-PMG approach as an econometric methodology for 11 Central and Eastern Europe (CEE) economies from 1995 to 2019. The findings from the empirical analysis indicate a significant long-run relationship between the two macroeconomic variables; however, the relevant relationship is estimated negatively. The findings for the short-run effects for the whole panel and country-specific estimations also confirm that higher government expenditure results in a statistically significant decline in real GDP per capita. Thus, the findings of this study do not empirically validate the Keynesian theory for 11 CEE economies covered in the research over the 1995-2019 period.
Unemployment and homeownership in Turkey: a preliminary analysis
(Işık Üniversitesi Yayınları, 2023-04-10) Susanlı, Zehra Bilgen
Using individual-level data, this paper aims to explore the link between homeownership and unemployment in Turkey. The Oswald hypothesis states that high homeownership is detrimental to labor market outcomes by restricting the geographical mobility of job searchers. Micro-evidence, however, indicates that homeowners have relatively favorable labor market outcomes. In contrast with the existing micro literature, the findings of this study are in favor of the Oswald hypothesis for the positive link between homeownership and unemployment probability.
An economic analysis of the communication skills in globalised industrial relations: social dialogue and the negotiation process in Turkey
(Univ Complutense Madrid, 2011-03-01) Soykut Sarıca, Yeşim Pınar; Şen Taşbaşı, Aslı
The purpose of this paper is to provide an economic analysis of the social dialogue experience in Turkey with an emphasis on the role of communication in industrial relations. We ascertain social dialogue -and the related negotiation process- as a major communication form in industrial relations and attempt to find out whether it serves well to promote consensus building and democratic involvement among the main stakeholders in employment. We particularly question the success of the existing social dialogue structures and processes in Turkey in resolving economic and social issues through communication, advancing social and industrial peace, improving competitiveness through increased productivity and complying international commitments in employment.
Revisiting discounted cash flows model as a capital budgeting decision tool
(PressAcademia, 2020-12-31) Teker, Suat
Purpose- In thisstudy, the classical discounted cash flows (DCDF) model is revisited and the input factors of the model are analysed in details. Methodology- A model analysis approach is used in this research. The fundamental assumptions and the input factors (cash flows, time period, risk, discount rate, etc.) of DCF model are questioned. Findings- NPV and IRR are two methods using discounted cash flows and oftenly applied for capital budgeting decisions. The assumptions used in the DCF analysis are very strong and not fitting well in the reality of practical life. Economic life of the project may be much longer or shorter than projected in the analysis. The computation of discount rate bases on subjective interpretations (weights of capital components, cost of debt, opportunity cost of equity). Estimation of cash flows is the most critical input of the analysis but generally the least weighted factor (CF or FCF, inclusion of only relevant cash flows, depreciation and interest expenses, installments, credit sales and purchases, etc.). Risk adjustment can be made either on the discount rate or expected cash flows. Moreover, the analysis of international capital investments makes the issue more complicated. Also, the inclusion of real options adds an economic value to the analysis. Conclusion- DCF is not straight forward a capital budgeting model anyone can easily use. The application of DCF requires expertise and a picky view on details. Nevertheless, the acceptance of capital investments utilizing DCF method can not be independent of overall company strategic goals.
Allocation of parents’ time to child care among Turkish families: evidence from Time-Use Survey
(Sosyal Bilimler Araştırmaları Derneği, 2014-06-01) Susanlı, Zehra Bilgen
This paper focuses on the time parents allocate to child care using data from the Turkish Time Use Survey 2006 in order to examine the determinants of parental time investment in child care. Findings from Tobit analysis indicate that number of children of either gender has no effect on the minutes fathers spend on child care which suggests the lack of parental preferences in time allocation. However, number of children of both genders is found to be positively associated with mothers’ time use. Results also suggest that mother’s education is positively and significantly associated with minutes both parents spend taking care of children. For both parents, we find no evidence of association between time investment and household resources.
Intracity price dispersion: evidence from Istanbul
(Zonguldak Bülent Ecevit Üniversitesi, 2017-10-01) İnanç Tunçer, Özlem
The existence of price dispersion is one of the most well known principles of economic theory. Earlier studies concentrated on international purchasing power parity (PPP) deviations. In recent years several studies have examined price dispersion within a nation’s borders. In this article the price dispersion among the districts of Istanbul is analyzed by utilizing a data set containing microeconomic price levels from bazaars, convenience stores, and supermarkets. According to results of the study, the prices of homogenous products, except fruit and vegetables, vary less than the prices of differentiated goods as one might expect. Results also indicate that, type of the seller of the product effects price dispersion among the counties of Istanbul.
