Yayın Crafting performance-based cryptocurrency mining strategies using a hybrid analytics approach(Elsevier, 2021) Chlyeh, Dounia; Hacıoğlu, Ümit; Tatoğlu, Ekrem; Yılmaz, Mustafa Kemal; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüCrafting and executing the best cryptocurrency mining strategy is vital to succeeding in cryptocurrency market investments. This study aims to identify the best cryptocurrency mining strategy based on service providers’ performance for cryptocurrency mining using a hybrid analytics approach, which integrates the Analytic Hierarchy Process (AHP) and Fuzzy-TOPSIS techniques, along with sensitivity analysis. The results show that hosted mining is the overall best cryptocurrency mining strategy, followed by home mining and cloud mining, based on both total cost of operations and cryptocurrency payout criteria. The empirical findings also suggest that the critical features of the highest performing service providers (i.e., hosted mining strategies and cloud mining) were their flexibility of contracts and the superior efficiency in terms of the daily payout. Finally, of the three location alternatives for home mining, Turkey ranks first compared to the U.S. and Europe.Yayın Sustainability to financial realities: A comparative study of renewable energy's impact on financial performance(Institute of Electrical and Electronics Engineers, 2024) Chlyeh, Dounia; Bayraktar, Erkan; Yılmaz, Mustafa Kemal; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study examines the impact of renewable energy (RE) performance on companies' financial performance, primarily focusing on RE-related sustainable development goals (SDGs) and environmental factors. We analyze a sample of 2,737 companies across 47 countries from 2009 to 2018 using panel data analysis. Our results suggest that the effect of RE performance can be understood through three phases: policies adopted, targets established, and actions implemented. Interestingly, RE policies negatively impact profitability due to the substantial costs incurred by companies. Moreover, RE-related SDGs are found to affect companies' financial performance adversely. However, environmental factors demonstrate a positive and significant impact on corporate financial performance, which is observed consistently across developed and emerging countries. Furthermore, RE performance targets and actions have a significant positive impact, specifically in developed countries. This highlights the complex relationship between RE initiatives and financial outcomes, highlighting differential effects across various stages of implementation and geographic contexts.Yayın Big data analytics capabilities and firm performance: An integrated MCDM approach(Elsevier, 2020) Yasmin, Mariam; Kılıç, Hüseyin Selçuk; Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study explores the interdependence of big data analytics (BDA) capabilities and the impact of these capabilities on firm performance using an integrated multicriteria decision-making (MCDM) methodology. Drawing on a rich data set obtained from selected case study firms in Pakistan, three MCDM tools, namely, intuitionistic fuzzy decision-making trial and evolution laboratory (IF-DEMATEL), analytic network process (ANP), and simple additive weighting (SAW), are employed to assess the relative importance of BDA capabilities and the relationship of these capabilities with the firm performance. The results show that BDA capabilities are interdependent, and infrastructure capabilities are the highest-ranked among all, followed by management and human resource capabilities, respectively. The SAW results indicate an association between BDA capabilities and firm performance. Moreover, BDA capabilities are more strongly related to operational performance than to market performance.Yayın Efficiency analysis of major airlines: Exploring the operational performance determinants in aviation(Springer, 2024) Yalçın, Kübra Çınar; Kuşakcı, Ali Osman; Tatoğlu, EkremThis paper evaluates the performances and dynamics of productivity changes of 38 airlines from different regions of the world between 2015 and 2019, assessing the effects of business model, alliance membership, the economic development level of the home country, and size on the operational performance of the airlines. In this regard, first, constant returns to scale (CRS) and variable returns to scale (VRS) input-oriented data envelopment analysis (DEA) models with three inputs and two outputs are implemented. The input-oriented CRS model super-efficiency DEA is also used to discriminate between efficient airlines. The Malmquist Productivity Index (MPI) estimates efficiency dynamics across time. Further, the determinants of operational efficiencies are assessed by applying Mann-Whitney rank-sum tests. The analysis results show that most airlines suffer from scale inefficiency. MPI signifies productivity deterioration in airlines’ performance. It is found that low-cost carriers (LCC) have performed better than full-service carriers and alliance member airlines are less efficient than non-member airlines. Additionally, developed country airlines show better performance than their emerging country counterparts. Lastly, the size of airlines measured in available seat kilometers (ASK) is found to have no statistically significant effect on performance.
