For this purpose, the abnormal returns of the companies which are listed in the Sustainability Index of Borsa Istanbul are compared with the rest of the companies during the “Coronavirus crash” which took hold of every financial market in the world. To determine if the businesses represented by the BIST SI are less impacted by the Covid-19 crash than the rest, an independent samples t-test is used. The primary approach used is event study methodology, where the LNV test for the BIST100 index is applied to confirm the impact of the \"event\" in question. Findings show that, like other financial markets, Borsa Istanbul had a price drop in March 2020. Also, it was observed that inclusion in the Sustainability Index reduced average loss. This implies that it is reasonable to make sustainable investments and, as a result, to be included in the sustainability indexes, as inclusion has been found to be particularly helpful in reducing loss during crisis times.","PeriodicalId":496761,"journal":{"name":"Uluslararası işletme ve ekonomi çalışmaları dergisi","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135344893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, different financial analysts and scholars in the financial system have tried to unravel the complexity of financial stability and have conducted theoretical and empirical research at different levels. This study aims to reveal the internal factors affecting the financial stability of participation banks operating as Islamic banks in Turkey. Therefore, we consider the data of 6 participation banks for the 2019Q1-2023Q1 period. Moreover, we assess the stability of participation banks with the Z-score, one of the most popular financial stability indicators. As a result of the analyses with the Driscoll-Kraay robust standard errors estimator, firstly, we found a negative relationship between risk-weighted and non-risk-weighted capital ratios and bank stability. Secondly, we concluded that while there is a negative relationship between bank stability and bank size, there is a positive relationship between cost-to-income ratio, loan ratio and deposit (funds collected) ratio and bank stability. Finally, among the diversification indicators, we observed a negative relationship between asset and fund diversification and bank stability; in contrast, there is a positive relationship between income diversification and bank stability. This study shows that the factors affecting bank stability from most to least are income diversification, fund and asset diversification, deposits (collected funds) ratio, non-risk weighted capital ratio, cost-to-income ratio, loan ratio, risk-weighted capital ratio and bank size, respectively.","PeriodicalId":496761,"journal":{"name":"Uluslararası işletme ve ekonomi çalışmaları dergisi","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136264038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many studies in the economics literature have examined the effects of these negativities from different perspectives. In this study, the relationship between financial innovation and CO2 emission, which is newly used in the literature, is examined for 14 OECD member countries. LLC and IPS unit root tests, Pedroni and Kao cointegration tests and FMOLS estimator were used in the analyzes for the period between 2009 and 2019. According to the findings obtained from the analyzes, it is seen that financial innovation, economic growth and urbanization have negative effects on CO2 emissions. In addition, in the results of Dumitrescu-Hurlin causality test applied in the study, it was determined that there is a bidirectional causality relationship between economic growth, urbanization and CO2 emissions, and a unidirectional causality relationship between financial innovation and CO2 emissions. In this direction, it is considered important that companies and governments should act together. It is considered that the creation of green loans by financial intermediaries for environmentally sensitive projects can encourage investors. In order to prevent environmental degradation from a holistic perspective, the government should take measures such as subsidies and tax reductions to encourage environmentally friendly projects.","PeriodicalId":496761,"journal":{"name":"Uluslararası işletme ve ekonomi çalışmaları dergisi","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136264037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firms operating in the sector had to continue their services in a competitive environment. For this reason, scientific studies and theses have been conducted on competition for firms operating in the field of civil aviation. The aim of the research is to profile the postgraduate theses prepared in the field of civil aviation and competition in Turkey by examining them bibliometrically. All postgraduate theses prepared in the field of civil aviation and competition in the National Thesis Center were included in the research. The number of theses prepared in the field of civil aviation and competition topic was determined as 24. Content analysis method, which is one of the qualitative research methods, was used in the research. It was determined that most of the theses examined adopted the qualitative research method. When the samples of the theses are examined, Turkish Airlines for 10 theses and Pegasus for 8 theses were taken as samples. The first five frequently used keywords are competition, airlines, airline transportation, competitive strategies, and civil aviation, respectively.","PeriodicalId":496761,"journal":{"name":"Uluslararası işletme ve ekonomi çalışmaları dergisi","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135149767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
