    The paper aims to analyse the structure of unemployed highly educated staff in the Republic of Srpska. As indicated, such structure shall enable analysis of unemployment of highly educated staff as well as of vacant jobs on the basis of gender and profession, thus demonstrating that more than 1/2 of the staff after graduation finds themselves at the Employment Agency. This survey shall provide data indicating the unemployment duration of highly educated staff, i.e. the time they spend waiting for their first job at the Employment Agency. Unemployment analysis throughout various regions of the Republic of Srpska shall be addressed in detail. Likewise, the relevant institutions of the Republic of Srpska, acting as proxies between highly educated people and the labour market, shall be integrated in the analysis. The paper shall be particularly focused on assessment of unemployment of highly educated people from the field of economy. The problem of unemployment in the Republic of Srpska has been particularly pronounced with the last few years (2009, 2010, 2011, 2012, 2013 and 2014). It is constantly deepened due to the inadequate enrolment policy by the Ministry and the inability of the labour market to absorb the staff in the real and the public sector. The analysis is not based exclusively on the Republic of Srpska. The measures to reduce unemployment of highly educated people in the Republic of Srpska shall also be introduced. It is evident that today’s soci-

    Creating a Decision-Making Model Using Association Rules
    (Taylor & Francis, 2017) Istrat, Višnja; Lalić, Nenad
    Being a highly significant and complex function of management, decision making requires methods and techniques that simplify the process of selecting one choice among all available options. Decision making is therefore selection of that particular choice over any of several alternatives. Because of the process complexity, a continuous research and improvement of the methods and techniques modern decision making involves is required. One of many modern business challenges is to discover any possible improvement in the decision-making process managers shall use in making the right decision. Any decision made by managers directly impacts the realized profit, business, and company’s position on the market. The fact is that mankind faces the decision-making problem in each phase of its social development, which has resulted in increased need for learning more about it. In this work, both the significance and application of association rules will be analyzed on an example of car sales business. The research was conducted on a sample of 1728 transactions in order to recognize and establish the association rules and then determine their impact on the sales and profit. For the purpose of this research, a large car sales database was used as a source of information, which is also described in this work. Once these association rules were established, they were then used to create a better and more complete market supply. The main contribution of the paper is providing business intelligence model for performing association rules in real-term business settings.

    We analyse characteristics of the three most commonly used methods for estimating loss reserves in non life insurance: the chain ladder method, the loss ratio method, and the Bornhuetter-Ferguson method. Our aim is to give a comparative anal- ysis of the results obtained from applying these methods to a practical case, and to put emphasis on their advantages and disadvantages.

    Measuring of The Goods and Labor Markets Efficiency: Comparative Study of Western Balkan Countries
    (ELIT - Economic Laboratory for Transition Research, Podgorica, 2019) RADUKIC, SNEZANA; MASTILO, ZORAN; KOSTIC, ZORANA; VLADUSIC, LJUBISA
    Numerous theoretical and empirical evidences confirm the assumption that more competitive markets are followed by raising the level of efficiency. The aim of this paper is to consider to what extent are efficient goods and labor markets in the efficiency-driven countries, such as Western Balkans. Intense competitive pressure both by domestic and foreign companies, and demand conditions determined by customer orientation and consumer sophistication, have great importance in acceleration labor market efficiency. The delicacy of the measuring of the competition and demand conditions on goods market completes an empirical review of the achieved results in labor markets in 2018 in Western Balkan countries. The multicriteria .analysis was carried out in order to rank countries and highlight those which have achieved remarkable goods and labor markets efficiency in the overall order of the countries. The obtained results suggest significant gaps and cyclical deviations from the regional average, related to goods market efficiency gaps, observed by selected indicators and countries. Problems in the fields of domestic competition, foreign competition, and insufficient quality of demand conditions in the individual markets, imposed the need to compare the comparative disadvantages and advantages in the Western Balkan countries. The comparative study can serve as a guide for defining future labor market policies due to it has been proven that countries with more efficient goods market have more favorable labor market indicators.

    A New Model for Stock Management in Order to Rationalize Costs: ABC-FUCOM-Interval Rough CoCoSo Model
    (MDPI, 2019) Erceg, Živko; Starčević, Vitomir; Pamučar, Dragan; Mitrović, Goran; Stević, Željko; Žikić. Srđan
    Cost rationalization has become imperative in every economic system in order to create adequate foundations for its efficient and sustainable management. Competitiveness in the global market is extremely high and it is challenging to manage business and logistics systems, especially with regards to financial parameters. It is necessary to rationalize costs in all activities and processes. The presence of inventories is inevitability in every logistics system, and it tends to create adequate and symmetrical policies for their efficient and sustainable management. In order to be able to do this, it is necessary to determine which products represent the largest percentage share in the value of procurement, and which are the most represented quantitatively. For this purpose, ABC analysis, which classifies products into three categories, is applied taking into account different constraints. The aim of this paper is to form a new model that involves the integration of ABC analysis, the Full Consistency Method (FUCOM), and a novel Interval Rough Combined Compromise Solution (CoCoSo) for stock management in the storage system. A new IRN Dombi weighted geometric averaging (IRNDWGA) operator is developed to aggregate the initial decision matrix. After grouping the products into three categories A, B and C, it is necessary to identify appropriate suppliers for each category in order to rationalize procurement costs. Financial, logistical, and quality parameters are taken into account. The FUCOM method has been used to determine the significance of these parameters. A new Interval CoCoSo approach is developed to determine the optimal suppliers for each product group. The results obtained have been modeled throughout a multi-phase sensitivity analysis
