Öğe Türü: Yayın , Integration of Arab Financial Markets: Opportunities and Obstacles(Vision for Scientific Research and Publishing (VSRP), 2025) Dawaba, Ashraf; Devabe, EşrefThe capital market is a fundamental pillar of economic growth. The reality of financial markets in Arab countries reveals that most of these nations have only recently established stock exchanges. Nevertheless, they have made significant progress in developing their financial markets over the past few years. Given the global financial changes and the increasing complexity of international variables driving the globalization of financial activities and the decline of national economic boundaries, there is an urgent need to enhance Arab financial integration. This would enable these countries to keep pace with global financial developments.In this context, this study examines the feasibility of integration among Arab stock exchanges. It explores the obstacles hindering this integration, as well as the opportunities that support it, by identifying commonalities among Arab financial markets. The study also considers the potential establishment of a unified Arab stock exchange and the expected impacts of such an initiative. These impacts include facilitating capital movement among Arab countries, encouraging the repatriation of Arab investments currently held abroad, attracting more foreign investments, providing necessary funding sources for productive projects, strengthening intra-Arab trade, and paving the way for comprehensive and anticipated Arab economic integration.Öğe Türü: Yayın , Measuring the Efficiency of Companies in Bist 30 Participation Index Bydata Envelopment Analysis(Liberty Publishing House, 2025) Balcı, Esra; Balcı, EsraIn today’s competitive business environment, measuring and improving efficiency is critical for companiesseeking long-term sustainability and market success. Firms must evaluate whether they utilize their financialresources effectively to generate optimal outputs. Companies must take corrective measures to address theirweaknesses if inefficiencies are identified. Efficiency enhances productivity and competitive advantage byachieving the highest possible output with the least input. This study assesses the financial efficiency of 14companies listed in the BIST Participation 30 index between 2019 and 2023. These companies operate invarious sectors, including chemicals, petroleum rubber and plastic products, transportation and storage, basicmetals, and defense industries. The BIST Participation index includes companies that comply with Islamicfinance principles. This study employs Data Envelopment Analysis (DEA), a widely recognized non-parametric methodology designed to evaluate the relative efficiency of decision-making units (DMUs) byconsidering multiple input and output variables. Three financial indicators were selected as input variables:Total equity, total assets, and total liabilities. The output variables included net profit, return on assets (ROA),and return on equity (ROE). The data for the analysis were obtained from the companies’ official financialstatements and the Public Disclosure Platform (KAP), a platform managed by the Capital Markets Board ofTurkiye (SPK), where companies listed on the Borsa Istanbul (BIST) are required to disclose their financialreports and other relevant information. The results show that five companies were efficient in 2022 and 2023,six were efficient in 2021, only one achieved efficiency in 2020, and five were efficient in 2019. The five mostefficient companies were identified as GESAN, ASELS, MAVI, BIMAS, and SASA based on the averageefficiency scores over the five years. This analysis provides a comprehensive understanding of firm-levelefficiency under Islamic financial principles. It offers investors, managers, and policymakers valuable insightsto enhance strategic financial decision-making and competitiveness in the Islamic capital market.Öğe Türü: Yayın , The Impact of Islamic Religiosity on Consumption Patterns: an Empirical Study on Muslim Consumers(SASE, 2025) Balcı, Esra; Balcı, EsraUnlike conventional economics, which does not address the moral dimension of consumer behavior, Islamic economics provides a framework that includes rewards and punishments for both moral and immoral actions,considering the consequences in both this world and the hereafter. An Islamic consumer is one whose behavioraligns with the teachings of Islam, particularly the Qur'an and Hadith. Such a consumer exercises control overdesires, lives according to moral principles, avoids harmful goods and services, and takes social responsibility byensuring the well-being of others. Furthermore, an Islamic consumer is committed to consuming only halal(permissible) goods and services and avoids haram (forbidden) practices. The Islamic consumer maintains a balanced approach, avoiding extremes such as miserliness or wastefulness, and allocates a portion of their resources to charity. Ultimately, an Islamic consumer prefers a simple and moderate lifestyle that reflects thesevalues. Consumption in accordance with Islamic principles is possible only under the guidance of Islam.Islamic rationality encourages consumers to maximize their utility while preserving religious, national, historical,cultural, and social values. The system directs individual behavior in accordance with the guidance of the Qur'anand Hadith, promoting ethical consumption, moderation, and social responsibility. Consumers are urged to maximize their utility while safeguarding their religious, cultural, and social values. The moral framework of Islamic economics emphasizes accountability, with rewards and punishments for behavior, taking into account the consequences in both this world and the hereafter.In this context, an Islamic consumer is defined as someone whose behavior reflects Islamic teachings. Such a consumer exercises control over desires, avoids harm to themselves or society, and consumes goods and services that are halal (permissible). The Islamic consumer prioritizes balance, avoiding extremes such as wastefulness or The main objective of this research is to analyze the impact of individuals' religiosity levels on their consumption tendencies. The study will examine not only ostentatious and luxury consumption but also halal consumption tendencies, as well as individuals' awareness and practices regarding recycling and reuse. Additionally, the effects of the presence and spread of Islamic banking on consumption tendencies will be evaluated. The research will discuss the determining factors influencing individuals' behaviors by taking into account their religiosity levels,consumption habits, and demographic characteristics.When examining religiosity scales in international literature, it is often found that these scales, originally developedto measure Christianity, do not provide meaningful results even when adapted for different cultures. Therefore, it isbelieved that a scale created within the context of Islam and Turkish cultural traditions would yield more significant outcomes. For this reason, the study will use the "Religious Orientation Scale" developed by Ahmet Onay (2002) to measure consumers' religiosity levels, ensuring that the items are tailored to reflect Islamic and Turkish culturaltraditions. This scale has shown an Alpha reliability coefficient of α=0.94 for students at Erciyes University andα=0.95 for students at Ankara University. The "Religious Orientation Scale" consists of three dimensions: 1)Thought (8 items), 2) Behavior (6 items), and 3) Emotion (4 items).When creating the survey on consumption tendencies, various questions were adapted and compiled from the coresources of Islam, primarily the Quran and Sunnah, works of classical Islamic scholars, and modern literature. Thesequestions were evaluated both in terms of content and language, and some were accepted without modification,while others were reworded to enhance clarity. The survey employs a 5-point Likert scale: "1. Never 2. Rarely 3.Sometimes 4. Often 5. Always."The data will be collected through a questionnaire. The population for the survey conducted in this research isdefined as the city of Istanbul, with a population of 15,462,452. The sample will be drawn from various districts ofIstanbul, using a convenience sampling method. The only criteria for participation in the survey are being 18 years or older and identifying as Muslim. The survey will be applied to individuals from diverse age groups, genders,marital statuses, income levels, and educational backgrounds, with no additional restrictions.The data obtained will be analyzed using SPSS software; Exploratory Factor Analysis (EFA) will be conducted for validity, and CronbachʼsAlpha test will be applied for reliability. The next step will involve conducting a regression analysis.This study aims to contribute to the creation of a framework compatible with Islamic understanding of consumption, rather than focusing on marketing products and services based on the new consumption habits ofMuslim consumers. The research seeks to make a significant academic contribution by redefining consumptionhabits in accordance with Islamic ethics and rules, partially distancing from the effects of capitalism and globalization.The research underscores the potential of Islamic values to foster ethical, balanced, and sustainable consumption patterns. By emphasizing moderation, responsibility, and social well-being, the study demonstrates how Islamicreligiosity can serve as a guiding framework for consumer behavior. In a world increasingly driven by materialismand consumerism, Islamic principles offer a viable alternative that aligns economic goals with moral and spiritualwell-being. This study contributes to bridging the gap between modern economic practices and Islamic ethics,providing a foundation for further research and practical applications in the field of Islamic economics and consumer behavior.Öğe Türü: Proje , The study develops a simulation-based model of a network economy where firms’ R&D efforts and input choices create innovation complementarities that can shift the economy between low- and high-innovation regimes. Using empirical evidence and MCMC simulations, it shows that the structure of industrial linkages critically shapes innovation outcomes, implying that effective policy must account for heterogeneity across sectors. -- Beta – Bureau d'Economie Théorique et Appliquée-University of Strasbourg, FranceÖğe Türü: Yayın , Proposing an Islamic Microfinance Model for Financial Inclusionin North Macedonia(Taylor & Francis, 2026) Rizvanovic-Mandal, Selma; Uluyol, Burhan; Uluyol, BurhanNorth Macedonia is a Western Balkan country with significant portion of Muslim population andat the same time the highest poverty rates, rates of unemployment, and lowest scores for financialinclusion of the poor and SMEs. Despite the high percentage of Muslims whose religiosity has beenon an upward trend since the breakup with the communist regime, there is no financial institutionthat works under the Shariah principles leaving the Muslims obeying Islamic provisions out of thefinancial services. This paper analyzes the challenges of the microfinance industry and points out analternative solution seen in introducing and developing Islamic microfinance. The main objectiveof the chapter is to examine the possibilities for the introduction of Islamic microfinance and topropose a model for North Macedonia. For that purpose, qualitative methods, literature review,and case studies were employed. The desk-based research consists of analysis of relevant literaturereviews, reports, and websites of significant institutions such as the UN and World Bank. A casestudy of a conventional microfinance foundation in North Macedonia and two Islamic microfinanceorganizations in neighboring countries provide essential suggestions for proposing an Islamicmicrofinance model appropriate for the Macedonian context. Islamic microfinance has the potentialto contribute toward socio- economic development and to improve financial inclusion in NorthMacedonia.
