The impact of information system capabilities on firm performance: A serial multiple mediating model
(Academy of Management, 2017) Aydıner, Arafat Salih; Bayraktar, Erkan; Tatoğlu, Ekrem; Tatoğlu, Ekrem; Yönetim Bilimleri Fakültesi, İşletme Bölümü
This study essentially investigates the effects of information system (IS) capabilities on firm performance. The combination of the resources and competencies that comprise IS capabilities is demonstrated using the resource-based view (RBV). A set of hypotheses is formulated to examine the impact of IS capabilities on decision-making performance and business process performance through the application of the serial multiple mediating model. Drawing on a sample of 204 firms in Turkey, the direct and indirect relationships among the study’s constructs are determined using structural equation modeling (SEM). The test results confirm the proposed serially mediating model. The study also demonstrates that multiple casual links are required for IS capabilities to have an impact on firm performance.
Developing a hybrid analytics approach to measure the efficiency of deposit banks
(Elsevier, 2019) Dinçer, Hasan; Hacıoğlu, Ümit; Tatoğlu, Ekrem; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme Bölümü
This study aims at analyzing the efficiency of deposit banks using contemporary analytics-based decision-making techniques within a fuzzy environment. Specifically, a hybrid analytic model drawing on a fuzzy analytical network process and data envelopment analysis was developed and applied to the assessment of Turkish deposit banks quoted on Borsa Istanbul. The findings revealed that; (i) the efficiency results for banking activity vary for competitiveness and for the adoption of new technologies before and after the financial recession; (ii) the majority of deposit banks operating primarily with non-interest based factors found to be less-efficient; (iii) the ownership and capital structure of banks do not significantly contribute to their banking performance, as they were technically inefficient during the same period; and (iv) the inputs of the banking activities could be reduced while a constant level of output is maintained by adopting and properly using the most efficient technology to boost the technical efficiency.
Environmental practices and firm performance in emerging markets: The mediating role of product quality
(Taylor & Francis (Routledge), 2019) Tatoğlu, Ekrem; Tatoğlu, Ekrem; Ahmed, Muhammad Usman; Gölgeci, İsmail; Bayraktar, Erkan; Tatoğlu, Ekrem; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Environmental practices have not received as much research attention in emerging market contexts as traditional topics like quality. However, the importance of environmental practices for a firm’s production strategy has been increasing at an unprecedented level across the globe. Our research objective is, therefore, to investigate the interplay between environmental practices and quality in the pursuit of firm performance. Relying on 492 responses from Turkish manufacturers to test our hypotheses, we show that environmental practices directly improve the quality of products over and above the effect of quality management practices in emerging markets. Product quality, in turn, is important for increasing firm performance, acting as a mediator for the positive effects of environmental practices on performance. Thus, we reveal that product quality functions as an instrumental conduit between environmental practices and firm performance in emerging markets like Turkey where stakeholder pressures are weak, and regulations are often not properly enforced.
Using machine learning tools for forecasting natural gas consumption in the province of Istanbul
(Elsevier, 2019) Beyca, Ömer Faruk; Ervural, Beyzanur Çayır; Tatoğlu, Ekrem; Özuyar, Pınar Gökçin; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Commensurate with unprecedented increases in energy demand, awell-constructed forecastingmodel is vital to managing energy policies effectively by providing energy diversity and energy requirements that adapt to the dynamic structure of the country. In this study, we employ three alternative popular machine learning tools for rigorous projection of natural gas consumption in the province of Istanbul, Turkey's largest natural gas-consuming mega-city. These tools include multiple linear regression (MLR), an artificial neural network approach (ANN) and support vector regression (SVR). The results indicate that the SVR is much superior to ANN technique, providing more reliable and accurate results in terms of lower prediction errors for time series forecasting of natural gas consumption. This study could well serve a useful benchmarking study for many emerging countries due to the data structure, consumption frequency, and consumption behavior of consumers in various time-periods.
Türkiye’deki işletmelerde bilişim sistemleri uygulamaları üzerine bir saha araştırması
(Gazi Üniversitesi, 2019) Tatoğlu, Ekrem; Tatoğlu, Ekrem; Aydıner, Arafat Salih; Tatoğlu, Ekrem; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
İşletmeler bilişim sistemlerini (BS) uzunca bir süre sabit kaynaklar olarak değerlendirmiştir. Bu yaklaşım yakın zamanda değişerek BS uygulamalarının değer yaratan bir ekosistem oluşturduğu sonucuna varılmıştır. Genellikle araştırmalar işletmelerdeki BS uygulamalarının göreli kullanımları ile performans değerlendirmesi arasındaki ilişki üzerine yapılmaktadır. Firmaya özgü durumların - sahiplik örüntüsü, firma büyüklüğü, sektör, firma yaşı - ise literatürde değişmeyen unsurlar olarak görüldüğünden yeteri kadar üzerinde durulmadığı saptanmıştır. Bu yüzden, firmaya özgü bu olası durumlar temel unsurlar olarak kabul edilerek, Türkiye’de çeşitli sektörlerde faaliyet gösteren 204 firma ile saha araştırması yapılmıştır. Toplanan veriler t-testi ve ANOVA metodları ile analiz edilerek BS uygulamalarının göreli kullanımı ile firmaya özgü durumlar arasındaki etkileşim incelenmiştir. Araştırmamızın sonucunda, farklı BS uygulamalarının göreli kullanımının firmaya özgü olası durumlarda değişim gösterdiği tespit edilmiştir. Aynı zamanda çalışmamız, BS uygulamalarının göreli kullanımı sonucunda oluşan firmaya özgü durumlardaki değişimin etkileri hakkında çıkarımlar yapmamıza katkı sağlamaktadır.
Bütünleşik Kalite ve Çevre Yönetimi uygulamaları: Kavramsal bir model önerisi
(Çanakkale Onsekiz Mart Üniversitesi, 2018) Ayaz Arda, Özlem; Tatoğlu, Ekrem; Alpkan, Lütfihak; Tatoğlu, Ekrem; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Bu çalışma esas olarak kalite yönetimi (KY) ve çevre yönetim (ÇY) sistemlerini bütünleştirmeye yönelik bir akademik çabayı içermektedir. Öncelikli olarak bu iki sistemin bütünleştirilmesinin altında yatan temel sebepler ve bununla ilgili rol oynayabilecek kurumsal dinamikler incelenmiştir. KY, ÇY ve kalite-çevre yönetimi (KÇY) boyutları kapsamlı bir literatür araştırması ile gözden geçirilmiş ve bunların firma performansı ile ilişkilerini ortaya koyan kavramsal bir model önerisi sunulmuştur. Ayrıca, söz konusu model önerisinin gerek yöneticiler gerekse akademisyenler açısından fayda ve önemi ile ilgili değerlendirmelere yer verilmiştir.
Corporate governance and firm performance in emerging markets: Evidence from Turkey
(Elsevier, 2019) Tatoğlu, Ekrem; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Çiftçi, İlhan; Tatoğlu, Ekrem; Wood, Geoffrey; Demirbağ, Mehmet; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
This is a study of the relationship between context, internal corporate governance and firm performance, looking at the case of Turkey, an exemplar of family capitalism. We found more concentrated ownership, often in the hands of families, led to firms performing better; concentrated ownership means that controlling families bear more of the risks of poor performance. Less predictably, given that the institutional environment is so well attuned to family ownership, we found that mechanisms that accord room for a greater range of voices and interests within and beyond families – larger boards and foreign ownership stakes – seem to also make for positive performance effects. We also noted that increase in cross ownership did not influence market performance, but was negatively associated with accounting performance. Conversely, we found that a higher proportion of family members on boards had no discernable effect on performance. Our findings provide further insights on the relationship between the type of institutions encountered in many emerging markets, internal corporate governance configurations and firm performance.
Business analytics and firm performance: The mediating role of business process performance
(Elsevier, 2019) Aydıner, Arafat Salih; Tatoğlu, Ekrem; Bayraktar, Erkan; Zaim, Selim; Delen, Dursun; Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Due to the rapidly increasing popularity of business analytics (BA), investigation of the antecedents/determinants of the adoption of BA and the subsequent impact of the same to the firm performance has become an important research topic. Drawing on the fundamentals of the resource-based view (RBV), this study proposes a model that examines the effects of the BA adoption on business process performance (BPER) and the mediating role that BPER plays in the relationship between the adoption of BA and firm performance (FP). Based on the data collected from 204 medium- to high-level business executives in various industries, the results of this empirical study indicate that the adoption of BA positively influences BPER. There is also positive relationship between BPER and FP. Finally, the results show that BPER fully mediates the relationship between BA adoption and FP.
HRM and performance the role of talent management as a transmission mechanism in an emerging market context
(Wiley, 2018) Glaister, Alison J.; Karaçay, Gaye; Demirbağ, Mehmet; Tatoğlu, Ekrem; Tatoğlu, Ekrem; Yönetim Bilimleri Fakültesi, İşletme Bölümü
This paper investigates the link between HRM practices, talent management (TM), and firm performance and examines the role of HRM/business strategy alignment in an emerging market context. Through survey evidence gathered from 198 respondent firms, this study shows that TM, when focused on a series of practices aimed at developing workforce networks and social capital, is a key transmission mechanism mediating the relationship between HRM and firm performance. HRM strategy and business strategy alignment increases these performance impacts but is not an essential component in the HRM-TM-performance link.
Performance evaluation of real estate investment trusts using a hybridized interval type-2 fuzzy AHP-DEA approach: The case of Borsa Istanbul
(World Scientific Publishing, 2019) Tatoğlu, Ekrem; Yılmaz, Mustafa Kemal; Kuşakcı, Ali Osman; Tatoğlu, Ekrem; Yılmaz, Mustafa Kemal; Kuşakcı, Ali Osman; Yılmaz, Mustafa Kemal; Kuşakcı, Ali Osman; Tatoğlu, Ekrem; İçten, Orkun; Yetgin, Feyzullah; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
This study proposes a three-stage holistic methodology combining an interval type-2 fuzzy analytical hierarchy process (IT2F-AHP) and data envelopment analysis (DEA) to deal with the performance evaluation problems encountered in fuzzy decision environments. In the first stage, prospective inputs and outputs are determined by field studies. The second stage employs IT2F-AHP to identify the most appropriate performance indicators based on vague expert judgements. Finally, DEA is applied to the decision-making units (DMUs) based on the selected set of input and output measures. The proposed methodology proves its merit on a case study addressing the performance of real estate investment trusts (REITs) in Turkey during their ten-year journey of trading on Borsa Istanbul (BIST). The results demonstrate that the average scores for technical, pure technical and scale efficiencies are 66%, 80% and 80%, respectively. Considering the technical efficiency scores, Turkish REITs could have reduced their input factors by an average of 34%. The findings also reveal that the majority of Turkish REITs suffer from economies of scale and could have improved their performance by expansion.
