This paper aims to generalize linear models for the multiproduct break-even point. Taking into consideration identified research gaps, the paper focuses on deriving formulas for determining the multiproduct break-even point through determination models. Different assumptions regarding the constancy of individual product contribution structures to total physical production volume, total revenue, total variable costs, and total contribution margin are taken into account. Additionally, connections between the obtained solutions from different models and different assumptions regarding the constancy of individual product contributions are established. The verification of the optimality of solutions obtained through different determination models is conducted by comparing them with solutions derived from linear programming as a benchmark. The developed models are tested using a case study of a multiproduct company in the metal processing industry. Through comparative analysis, the hypotheses concerning obtaining an optimal solution and the identical nature of solutions derived from the determination model and linear programming are examined. This paper contributes to the understanding of the multiproduct break-even point, providing a theoretical and practical framework for evaluation and enabling the application of various determination models in the context of a multiproduct situation.

The purpose of this work is to show the development and evaluation of behavioural intentions of students by using mobile banking. The research goal is to explain determinants of students’ intentions towards the use of mobile banking. PLS SEM (partial least squares structural equation modeling) analysis was used for the model evaluation. The sample consists of 83 students from four higher education institutions operating in Bosnia and Herzegovina (B&H). Research results confirmed that subjective norm and attitude are significant predictors of the user’s attitude towards mobile banking acceptance, while the influence of self-efficacy was not determined. Attitudes related to mobile banking acceptance are primarily determined by perception of usefulness and self-efficacy, and to a lower degree by perception of privacy and security risk. Perception of mobile banking usefulness appeared to be the most significant predictor of attitudes, while simultaneously it influenced positively on acceptance of behavioral intention, including intervening effect of attitude variable. Digital literacy was proved to be a significant predictor for self-efficacy. From the perspective of banks, it is very important to see how a generation that a high potential for the use of modern technologies has perceives mobile banking, and what affects it to accept mobile banking. The results of this research are useful for banks to attract new younger users of mobile banking and increase their own benefits.

The purpose of this research is to provide some insights into socio-demographic determinants of predicting the likelihood of residents propensity to travel. Using the quota sampling technique, data collection was carried out from October to December 2019, yielding a sample of 632 valid responses. To gain a better understanding of the sociodemographic determinants of propensity to travel, we, primarily, use descriptive statistical analysis, chi-square test and probit regression model. The research findings have revealed that age, education and household income characteristics may be considered as antecedents of travel propensity of residents. Having in mind the impact that Covid-19 pandemic has on sector of tourism worldwide, and based on the results of this research, policymakers' efforts should be directed to promoting local tourist destinations and to enhancing tourism literacy of residents.

Abstract The main goal of this article is to examine risk aversion impact on securities portfolio performance in underdeveloped capital markets. For the purpose of this research, portfolio performance was taken as a dependent variable, whereas investors’ attitude towards risk was considered as an independent variable. The analysis results have revealed that, ceteris paribus, an increase in risk aversion leads to a decrease in expected return and the creation of more superior securities portfolio. The article is expected to produce useful pieces of information which might be helpful for investors in the process of creating their portfolios in underdeveloped capital markets.

In this paper it is described aspects of standardisation of information security and itsimplementation in banking and insurance companies in countries of Western Balkans. Interms of approaching the standards of EU, one of the areas that need to be fully justified isthe information security. It has been identified and applied a new dual methodology whichcovers measurement of same variables of information security into two opposite populations.Authors identify banking and insurance sector as a key sector for research due to sensitivityof financial data and information that these companies work with. Key obstacles inimplementation of information security come from managers who consider that existing levelof information security is on much higher level than it actually is. The authors have identifiedintensity of perception of information security and gap in perception between managers offinancial institutions and auditors, and rank of significant properties of information security.Factor analyses were conducted and four factors were identified which show managers’perception of information security. Also, the authors have identified attributes of marketingaspects of information security and market potential of information security of banking andinsurance sector in countries of Western Balkans.
