Öğe Türü: Yayın , Shariah Governance Frameworks for Equity Crowdfunding: An Analysis and Proposal(İstanbul Sabahattin Zaim Üniversitesiİslam Ekonomisi ve Finansı Dergisi (İEFD), 2025) Çıkıryel, BurakThe rapid expansion of equity crowdfunding in Türkiye has revealed a significant demand from investors for Shariah-compliant opportunities. However, the absence of a formal Shariah governance framework has created critical vulnerabilities, including erosion of trust, information asymmetry, a clear legal void and ambiguity of liability, inadequate due diligence, reputational and sustainability risks, unnecessary operational burden, voluntary financial exclusion, and systemic risk, which undermine the integrity of this emerging market. This study addresses this governance deficit through a qualitative analysis grounded in a critical literature review. Its primary contribution is twofold: first, it systematically maps the specific Shariah governance challenges inherent in Türkiye's crowdfunding ecosystem; second, it proposes three distinct, practical governance models to resolve them. These models are: (1) the Two-Tier Shariah Governance Model, which establishes a central authority and specialized platforms; (2) the Hybrid Model, which integrates an "Islamic window" into existing platforms; and (3) the Outsourced Shariah Governance Model, which standardizes third-party compliance verification. The implementation of any of these frameworks would institutionalize trust, mitigate risk, and foster the sustainable development of equity crowdfunding in Türkiye, serving as a template for other jurisdictions facing similar challenges.Öğe Türü: Yayın , COVID-19 Effect on Corporate Social Responsibility (CSR) Activities: A Comparison Between Islamic and Conventional Banks of Bangladesh(İstanbul Sabahattin Zaim Üniversitesi, 2025) Al Masud, AbdullahThe Coronavirus pandemic, or COVID-19, has caused a structural shakeup in the economy and healthcare throughout the world. Businesses faced a plunge in profit numbers, if not losses. Despite the crisis, many firms have contributed to society to help the economy survive and recover from the crisis. The objective of the study is to evaluate the CSR contribution by Islamic and conventional banks of Bangladesh pre-COVID and during COVID years.The study used both parametric and non-parametric techniques to compare the CSR ratios, profitability, and asset growth before and during the COVID years. The findings revealed that Islamic banks outperformed conventional banks in terms of CSR contribution both before and during the COVID years despite conventional banks being more profitable than Islamic banks. The central bank also made necessary changes to CSR guidelines for the CSR funds of banks for essential sectors such as healthcare, education, and disaster management. It can be concluded that Islamic banks, supposedly driven by ethical consideration of religion, indeed outperformed the conventional banks in Bangladesh. The experience of this systemic pandemic may guide both policymakers and institutions to tackle the worst effects of man-made or natural disasters through CSR efforts.Öğe Türü: Yayın , Determinants of Card Interchange Fee and Merchant Fee in Türkiye and Its Evaluation from the Perspective of Islamic Finance(İstanbul Sabahattin Zaim Üniversitesi, 2025) Eren, BekirThe aim of this study is to indicate the structure of card interchange fee and merchant fee, and to investigate whether there is a relationship between the interest rate and these fees in Türkiye. Using the Central Bank of the Republic of Türkiye and Competition Board regulations and explaining the two-sided structure of card market, the source of the interchange fee and merchant fee is asserted. The study reveals that the interest rate is the main determinant of these fees through funding cost channel. On the other hand, the operational costs have a small share in these fees. The merchant fees vary depending on time and interest rate owing to the interest-sensitive structure. Also, the interchange fee is a significant component of the merchant fee in not-on-us transactions. The study demonstrated that, despite all banks being subject to the same regulations and using the same infrastructure, treating merchant fees solely as a service fee in Islamic banking is inappropriate. Furthermore, contrary to the assumption in Islamic finance literature, it appears that transferring the money owing to card transactions to the business’s account on the next day is not the obligation of the banks; however, it is a preference of the business. Therefore, a new perspective is needed to explain the source of these fees in Islamic finance. In current practices, if there is a suspicion of interest in terms of Islamic finance in the merchant and interchange fees, banks and merchants may need to change their business models and contracts. Finally, understanding the exact source of merchant fee may reduce the asymmetric information for merchants and may increase the bargaining in contracts.Öğe Türü: Yayın , Bibliometrical Analysis of Studies in the Field of Islamic Economics Based on Scopus Database(İstanbul Sabahattin Zaim Üniversitesi, 2025) Ulusay, NurtenIn recent years, the field of Islamic economics has demonstrated remarkable growth at both national and international levels. In particular, countries such as Malaysia have emerged as important centers for Islamic finance and economics. This study aims to present a bibliometric analysis of academic research in the field of Islamic economics. By examining the scope, quality and impact of existing studies, it provides a comprehensive overview of trends, key topics, methodologies and research gaps in the literature. Data collected from the Scopus database were analyzed using RStudio software to identify patterns within the field. The findings highlight the increasing academic interest in Islamic economics and emphasize the social significance of concepts such as Islamic finance and banking. Moreover, the analysis identifies the leading countries contributing to this body of research and reveals the interdisciplinary nature of Islamic economics studies, which span economics, finance and Islamic law. Overall, the study offers valuable insights for future research by guiding scholars to address emerging gaps and explore the evolving dynamics of Islamic economics.Öğe Türü: Yayın , Faizli Bir Bankanın Faizsiz Bankaya Dönüştürülmesi ve Katılıma Dönüşüm Bankası Uygulaması(İstanbul Sabahattin Zaim Üniversitesi, 2025) Bulut, Yakup; Yumuşak, İbrahim Güran; Yumuşak, İbrahim Güranİslami bankacılığın dünyadaki gelişimine baktığımızda faizli bir bankanın faizsiz bankaya dönüştürülmesine yönelik son dönemlerde çok sayıda örne ğin olduğu görülmüştür. Bu örneklerde faizli bir bankanın tam teşekküllü faizsiz bankaya dönüşümünü görebildiğimiz gibi, faizsiz pencere açmak veya bağlı ortaklık kurmak şeklinde kısmi ve aşamalı dönüşüm şekillerini de görmek mümkündür. Bu makalede faizsiz bankacılık sektörünün gelişimine katkı sağlamak amacıyla yeni bir yöntem olarak katılım bankacılığına dönüşümün Türkiye’de uygulanması konusu başta dünya örnekleri olmak üzere birçok açıdan analiz edilmeye çalışılmıştır. Bu kapsamda faizli bir bankanın faizsiz bankaya dönüşümü fıkhî, hukukî, iktisadi, finansal ve teknik bakımdan değerlendirilerek, Türkiye koşullarına uygun katılıma dönüşüm bankası uygulaması ele alınmış ve dönüşüm sürecindeki bankalar için yeni bir isim önerisinde bulunulmuştur. Ayrıca sağlıklı bir dönüşüm süreci için ise öncelikli olarak yasal ve faizsiz bankacılık standartlarına yönelik fıkhî altyapı oluşturulması gerektiği kanaatine varılmıştır.
