Entropy-based Waspas approach for financial performance in the COVID-19 era : evidence from Islamic countries

The purpose of this study is to compare financial performance of the Islamic banks in the COVID-19 Era. The performance evaluation was conducted on seven Islamic countries between 2017 and 2021. Entropy Method was utilized to choose the best performance evaluation criteria affecting the Islamic banks' performance and Waspas Method was used to determine the best performing Islamic country. The results indicate that 'liquid assets to short-term liabilities' is the best performance criteria for Islamic banks during the 'whole period', 'no pandemic period' and 'pandemic period'. Additionally, while the Islamic country with the best performance was Bangladesh during 'no pandemic period', Turkey was the leading Islamic country for both 'whole period' and 'pandemic period'.
