This study contributes to sustainable finance literature by exemplifying promotion of sustainable finance through fintech solutions for emerging market economies by presenting the case of Turkey. Turkey is one of the largest emerging market economies in the world with a strong banking system and high adoption of technology, so it has great potential to benefit from fintech solutions to boost sustainable finance. For the case analysis, the data used came from a research platform for a Turkish start-up ecosystem, Turkish regulations, and documents released on Turkey’s sustainable finance strategies by Turkish and international institutions. We found that Turkey has made remarkable progress in increasing financial inclusivity for underbanked individuals and SMEs via providing contactless payment and contract systems and microfinance by mobile carriers and other online platforms. Turkey was also able to promote the responsible consumption goal for sustainable development by improving fintech solutions on payment systems with educational content on this goal. With upcoming developments such as the sandbox environment in Istanbul Financial Center, fintech solutions using Big Data, AI, and blockchain could emerge much faster with collaboration between banking and fintech sectors and regulatory institutions to better assess climate-related financial risks and form a national carbon trading mechanism.

Tr en Ülkemiz, jeopolitik konumu gereği ekonomik ve askerî riskler altında bulunmaktadır. Tarihçemize bakıldığında da savunma sanayine önem verilmesi gereken bir konumda olduğumuz anlaşılmaktadır. Savunma sanayinin gelişimi kavramına bakıldığında ise iç ve dış kaynaklardan ihtiyaçların karşılanması ile gelişim sağlandığı görülmektedir. Savunma sanayindeki gelişmelerin tanımlanmasında literatürde alınan patentler ve istihdam oranı gibi değişkenler temel alınmaktadır. Bu değişkenleri tanımlayan ölçüm değerlerinden biri savunma harcamaları olup harcamaların, savunma ihtiyaçlarının iç veya dış kaynaklardan karşılanması için yapılıyor olması durumuna göre ekonomik büyümeye etkileri farklı olabilmektedir. Bu çalışmada, farklı zamanlarda literatürde yer alan araştırmalar derlenerek savunma sanayinin gelişimi için yapılan harcamaların önemli bir makroekonomik değişken olan ihracat-ithalat dengesi üzerindeki etkileri araştırılmıştır. Farklı dönemlerde yapılan araştırmalarda savunma sanayi için yapılan harcamaların, savunma sanayinde teknolojik düzey arttıkça hem kısa, hem de uzun vadede ihracat-ithalat dengesinde ihracat yönünde olumlu etki yaptığı gözlenmiştir. Dolayısı ile savunma sanayi yerelleştikçe dış ticaret hacminde ithalatın payı gittikçe düşmektedir. Our country is under economic and military risks due to its geopolitical position. Due to our history, it is understood that we are in a position to give importance to defence industry. When the concept of developments in defence industry is examined, it is seen that development could be provided by meeting the needs from internal or external sources. In defining the developments in the defence industry, variables such as patents and employment rate are taken as basis in the literature. One of the measurement values defining these variables is defence expenditures, and the effects of the expenditures on economic growth may be different depending on whether the defence needs are met by internal or external sources. In this study, the effects of the expenditures made for the development of the defence industry on the export-import balance, which is an important macroeconomic variable, have been investigated. In the researches carried out at different periods, it was observed that the expenditures made for the defence industry had a positive effect on the export-import balance in both short and long term as the technological level in the defence industry increased. Therefore, as the defence industry is localized, the share of imports in foreign trade volume is decreasing.

This study explores the effect of syndicated loan announcements on the stock returns of banks listed on Borsa Istanbul, utilizing the event study methodology over the 2017–2022 period. Eight publicly traded banks were analyzed to assess abnormal returns (AR), average abnormal returns (AAR), and cumulative abnormal returns (CAR) within an extensive event window. The findings reveal that syndicated loan announcements did not result in statistically significant abnormal returns, indicating a deviation from the semi-strong form of market efficiency in Borsa Istanbul. Unlike previous studies, this research makes an original contribution by focusing specifically on syndicated loan events in an emerging market context, applying a longer observation window and a rigorous empirical setup. By isolating bank-specific stock reactions to syndicated loans, the study enhances the understanding of informational efficiency in developing capital markets. Moreover, it addresses an underexplored topic in Turkish financial literature, offering new insights for investors, policymakers, and academics interested in market behavior and external financing announcements.

This study examines the financial resilience of European Air Navigation Service Providers (ANSPs) before and after the COVID-19 shock. Using a balanced panel dataset covering 2017–2023 for over 30 ANSPs, we employ fixed-effects estimators to quantify changes in key financial metrics—revenue, operating costs, capital expenditures, and free cash flow—once air traffic volumes collapsed. Our findings reveal a pronounced downturn in profitability and liquidity in 2020, followed by uneven recovery trajectories across providers. We also identify factors—such as pre-pandemic leverage and cost structure—that moderated the depth of the shock. These insights contribute to crisis-management literature in aviation finance and offer policy implications for bolstering sectoral sustainability against future disruptions.

Yapay zekâ özünde makine öğrenimi, doğal dil işleme, bilgisayar görüşü ve robotik gibi bir dizi teknolojiyi içermektedir. Bu araçlar, sistemlerin büyük miktarda veriyi analiz etmesini, içgörüler çıkarmasını ve otonom kararlar almasını sağlamakta, bu da organizasyonların işlemleri optimize etmelerini, verimliliği artırmalarını ve müşterilere özel deneyimler sunmalarını sağlamaktadır. Dahası, yapay zekânın yayılması yalnızca tek bir sektörle sınırlı kalmamakta, neredeyse modern yaşamın her yönünü sarmalamaktadır. Sağlıkta, yapay zekâ teşhisi desteklemekte, ilaç keşfini ve kişiselleştirilmiş tedavi planlarını sağlamakta, hasta bakımını ve tıbbi araştırmaları devrim niteliğinde değiştirmektedir (Gadde and Kalli, 2021:314). Finansta, yapay zekâ algoritmaları ticaret stratejilerini optimize etmekte, dolandırıcılığı tespit etmekte ve kredi riskini değerlendirmekte, bu da verimliliği artırmakta ve finansal riskleri en aza indirmektedir.

The aim of this research is to determine the difficulties encountered by green entrepreneurs who contribute to the green economy while carrying out their activities, and to contribute to the literature and young entrepreneurs from the success stories of these entrepreneurs. The “interview technique”, one of the qualitative research methods, was used in the research. In the study, interviews were conducted with 12 entrepreneurs who carry out entrepreneurial activities in the Southeastern Anatolia Region. The research data were analyzed with the Maxqda 2024 program and the problems encountered by the interview participants in green entrepreneurship were examined with the word cloud. According to the results of the research, it was stated that entrepreneurship in Turkey needs to be supported by the state, green entrepreneurs and large-scale entrepreneurs earn. It was reported that the state planned production to prevent surplus production, that the support of small-scale entrepreneurs was very little, and that the earnings of those who sell quality products increased.
