One of the frequently mentioned issues in the literature is that studies analyzing the relationship between corporate sustainability and financial performance do not reach a consensus on the existence and direction of the relationship. This study is aimed to contribute to the literature by analyzing the relationship between corporate sustainability practices and financial performances of 58 non-bank firms included in the Borsa Istanbul (BIST) Sustainability Index between the years 2015-2021. The study employed the System Generalized Method of Moments (system GMM) estimator, which is one of the dynamic panel data models. The results of the analysis can be summarized as follows; (i) there is a positive relationship between corporate sustainability practices and both market-based and accounting-based financial performance indicators, (ii) corporate sustainability positively affects different financial performance indicators at different terms, (iii) sustainability investments affect the market value of businesses more and faster than the return on assets, and (iv) the relationship between corporate sustainability and financial performance is dynamic, and the endogeneity problem should be taken into account in the analysis of the relationship between them.

The e-commerce sector has grown beyond predictions with the help of the most recent technological developments, changes in consumer preferences, and the COVID-19 pandemic. E-commerce activities assume a subsidiary role of brick-and-mortar shops with the benefits it offers to all parties, which have also resulted in new problems such as privacy, security, transparency, and costs, unlike traditional businesses. Blockchain technology is among the promising technologies in solving the problems of the e-commerce sector with its decentralized structure that does not require third-party intermediaries, and its features (such as privacy, immutability, security, transparency, and auditability). In this study—which examines, under five titles, the benefits that blockchain can offer to e-commerce—it is concluded that blockchain can reshape e-commerce activities by enabling integrated e-commerce systems that include all parties and offering low transaction costs, high transaction speed, traceability of transactions, strong security standards, and low risks. In this direction, blockchain-based e-commerce platforms can push existing e-commerce platforms into the background.

Financial management inadequacies in the football industry have enlarged concerns about the financial sustainability of clubs during the COVID-19. In this regard, this study aims financial performance analyses and performance rankings of the four football clubs trading on the Borsa Istanbul. A method that integrates CRITIC and GRA techniques was used in the study. It was concluded that clubs whose revenues decreased due to the discontinuance of their activities during the pandemic acted more prudently in monetary terms. Additionally, the club with a high average financial performance over the previous years has financially been less affected by the pandemic.

Tertiary education is accepted as one of the engines of economic growth at national level. However, as far as is known, there have been only a few research studies in literature on efforts to increase quality level of tertiary education institutions that have both an extensive data set and are based on the context of a developing country. Therefore, this study aims to examine the current situation of quality management efforts in Turkish tertiary education Institutions. The data for this study were collected from 672 units of 149 Turkish universities. According to the findings, more than half of the participating organizations did not have any quality management certificate, nor were they making any quality management efforts. Therefore, the findings indicated that there is still a very long and arduous way to be covered by Turkish tertiary education ınstitutions in spite of some important developments.

Tr en Bu çalışmanın amacı gelişmekte olan bir ülke konumundaki Türkiye’de, 2007-2015 yılları arasında BIST Kurumsal Yönetim Endeksi’nde işlem gören firmaların finansal performansları ile kurumsal sosyal sorumluluk düzeyleri arasındaki ilişkiyi analiz etmektir.  Çalışmada, Türkiye’de yapılan diğer çalışmalardan farklı olarak dinamik bir metot olan Sistem Genelleştirilmiş Momentler Metodu (sistem GMM) kullanılmıştır. Çalışmada bağımlı değişken olarak muhasebe temelli ROA ve piyasa temelli Tobin’s Q olmak üzere iki oran, bağımsız değişken firmaların kurumsal sosyal sorumluluk notları kullanılmıştır. Ayrıca finansal kaldıraç ve firma büyüklüğü kullanılan araç değişkenlerdir. Analiz sonucunda, firmaların KSS düzeyleri ile iki performans göstergesi arasında da istatistiksel olarak pozitif ve anlamlı bir ilişki olduğu sonucuna ulaşılmıştır. The objective of this study is to examine whether there is a relationship between the performances and corporate social responsibility levels of companies traded in BIST Corporate Governance Index between 2007 and 2015 in Turkey, which is an emerging market. Different from the previous studies conducted in Turkey, the analysis is conducted with a dynamic method, the System Generalized Moments Method (system GMM).

Bu çalışmanın amacı gelişmekte olan bir ülke olan Türkiye’de, 2007-2015 yılları arasında kurumsal yönetim endeksinde işlem gören firmaların performansları ile kurumsal yönetim düzeyleri arasında ilişki olup olmadığının incelenmesidir. Analiz Türkiye’de yapılan diğer çalışmalardan farklı olarak dinamik bir method olan Sistem Genelleştirilmiş Momentler Metodu (sistem GMM) kullanılarak yapılmıştır.
