This study aims to empirically investigate the determinants of online banking adoption in Bosnia and Herzegovina. The data presented in this paper was collected via a survey from 321 randomly selected banking users in Bosnia and Herzegovina. The survey was developed based on the Technology Acceptance Model (TAM) framework to test the constructs and their ability to predict consumers’ behavioral intentions. All gathered data was processed and analyzed using the AMOS software version 24. We performed the Structural Equation Modeling (SEM) for path analysis to estimate the strength of the hypothesized relationships among the determinants. The findings indicate a significant impact of Attitude, Perceived Usefulness, and Perceived Ease of Use on consumers’ Intention to Use online banking services. Further, the research has proven that Perceived Usefulness and Perceived Ease of Use impact consumers’ Attitudes toward online banking adoption. The path analysis result suggests that Perceived Usefulness strongly mediates the relationship between Perceived Ease of Use and Attitude.

The main objective of the study is to empirically investigate the impact of the Conventional stock market index on the Islamic stock market index and the comparative performance of the two stock market indexes. For the purpose of the study, daily observations of Dow Jones Islamic Market US Titans 50 (DJUS50) and Dow Jones Composite Index (DJA) spanning a period from January 2015 until December 2021 are obtained from the Investing.com database. Risk-adjusted performance, VAR model, granger-causality test, generalized impulse response functions, and Johansen cointegration tests are used to investigate the behavior and performance of the Islamic market index empirically. Results based on risk-adjusted performance indicate that the Islamic market index performs better than the Conventional market index. Furthermore, the results suggest no long-run association between the indexes, while there is short-run bidirectional causality. This study will contribute both to the literature and practice. It will contribute to the already existing literature through the usage of the newest data, while the practical implication will help investors to better understand the behavior of the Islamic stock market index.

The main objective of this study is to compare the performance of two areas of banking in Bosnia and Herzegovina, that is, Islamic and conventional banking. In order to measure the performance of two banking sectors, profitability, efficiency and liquidity measures are implemented. For the purpose of the study secondary data from both banking sectors is used. The time interval covered in the study spans from 2008 to 2020. Ratio analysis and independent sample t-test is applied in order to check the characteristics of two banking sectors. Currently, studies investigating comparative performance of these two banking sectors in BiH are rare, therefore theoretical contribution will be evident. Practically, it will help bank customers to understand how Islamic banking sector performs relative to the conventional banking sector. Also, bank managers of selected banks will be able to compare performance of their banks relative to the other banks in terms of the ratios used in the study. The limitation of the study is that in Bosnia and Herzegovina there is only one bank that operates according to Islamic banking principles, which will represent Islamic banking sector in this study.

The main aim of the study was to empirically investigate and understand the effects that autonomy has on job satisfaction and job performance in Bosnia and Herzegovina. The empirical data was obtained from a questionnaire of 242 people living and working in Bosnia and Herzegovina. Once the data was collected, data analysis was conducted to assure validity and reliability through items’ loadings and Cronbach’s Alpha values.Furthermore, the scales were tested for convergent validity through partial least-square path modelling using SmartPLS 3 software. The results indicated that the effects of autonomy on job performance and job satisfaction were significant and had positive relationship.

This paper analyzes the vollatility spillover between the conventional index in Malaysia FTSE Malaysia KLCI (KLSE) and the Islamic index in Malaysia FTSE Bursa Malaysia Shariah Index (FTFBMHS). Monthly observations spanning in a period from 2002 to 2018 are obtained from investing.com database. GARCH model and Johansen cointegration test are used to investigate volatility spillover and the relationship between two indices. The results of the analysis indicate that in the short-run there is volatility spillover between FTSE Malaysia KLCI and FTSE Bursa Malaysia Shariah Index, while in the long-run there is no relationship between the two indices. The methodology of compiling Islamic indeces is based on Shariah law. Keywords: Conventional

This paper empirically examines tradeoff between risk and return for the Islamic stock market index in Bosnia and Herzegovina (BiH) (SASXBBI) and compares it with risk-return tradeoff of the conventional stock market index in BiH (SASX-30). Furthermore, it examines the eventual impact of the conventional stock market index in BiH on the SASXBBI. The study used daily index observations spanning in the period from October 2016 until December 2018. The data were obtained from the Sarajevo Stock Exchange database. The risk-reward ratio is used to investigate the tradeoff between risk and return of the indices, while Ordinary Least Squares (OLS) regression analysis is used to investigate the impact. The results show that there is better risk-reward tradeoff in the conventional index in BiH compared to the Islamic index in BiH. Also, the results suggest that conventional index return has a significant positive impact on Islamic index return in BiH.

Increasing popularity of online banking systems instead of traditional branch networking requires understanding customer behaviors as users of such systems. This research aims to investigate online banking acceptance among Bosnian university students by considering system, user, acceptance and performance related factors by considering a new relationship between perceived system security and perceived system quality. According to the results, the users perceive that (1) online banking system is not secure and poorly qualified but useful and easy to use; (2) the users themselves are slightly capable of using the system; (3) they have intention to use the system but don’t use the system; and (4) they are slightly satisfied with the system and increase their benefits. The results also provide that all hypotheses except the relationship between perceived ease of use and intention to use are supported. Perceived System Security, as a new dimension, is found to have positive effect on Perceived System Quality. It can be implied that if the system is qualified and the users are self-efficient about using the system, they perceive the system as easy to use and useful. It is suggested that banks better take necessary steps to persuade their customers about the system security and usefulness in completing their tasks.
