This study investigates the determinants of bank profitability in 23 countries from 2002 to 2016 using system generalized method moments. The findings indicate that number cards issued, automated teller machines (ATMs) and point sale (POS) terminals can improve profitability. Hence, this suggests a need for further expansion these delivery channels. Also, show negative impact market power on profitability, implying competition improves Further, positive relationship between capital...
The evolution of the COVID-19 pandemic is highly unpredictable; however, its impacts are limited to neither a single sector nor country. This study evaluates performance and efficiency 49 Islamic banks across 10 countries during 2019-2020 assess how those can preserve their remain resilient in aftermath pandemic.

Airlines and airports continuously improve operational efficiency enhance service quality, especially through self-service technology (SST). Although there are several reviews on SST, the aviation industry has been comparatively overlooked. This study offers a systematic review of existing literature SST (e.g., self-check-in kiosks web/e-ticketing) from customer perspective. Starting rich dataset 678 peer-reviewed journal articles listed in Scopus, after some screening processes, 98 remained...

How we can apply big data analytical tools such as machine learning to examine performance MSMEs has become an important question provide quicker results recommend better reliable solutions that improve performance. This paper proposes a novel method for estimating common set weights (CSW) based on regression analysis envelopment (DEA) operational research...
Purpose The financial system has witnessed the substantial growth of technology (fintech) firms.

More specifically, negative bank implies that more developed with less efficient systems. Meanwhile, positive impact on suggests may serve as wake-up call Therefore, should be encouraged by authorities world.

Abstract This study uses the multi-criteria decision-analysis (MCDA) approach to construct a composite performance index (CPI) directly from CAMELS financial ratios. The CPI has several promising characteristics, such as (i) being an absolute measure of that allows for adding or removing data without affecting existing scores; (ii) employing ratios in its calculation need normalization imputation positive values; (iii) dynamic weighting system envelopment analysis (DEA); (iv) providing more...
This paper examines the production efficiency of 2079 rice farms in Hanoi (Vietnam) 2018 and role formal informal knowledge on their efficiency. Our empirical results showed that, general, Hanoi’s performed quite well 2018. The differences specific performance each farm could be explained by farmer’s characteristics (age, education gender head household) as certain external factors (support programs or distance to city center). We found that self-learning through experience did not obviously...
