This paper attempts to empirically estimate the equilibrium exchange rate level of the Serbian dinar. For that purpose, the macroeconomic balance approach (MB) is used, developed by the IMF’s Consultative Group on Exchange Rate Issues (CGER). The research was made by using panel data series. The testing of regression parameters variability was perf...
During the last two decades there is a growing awareness of the importance of introducing organic agricultural production in Serbia due to issues of health, environmental protection and need for more sustainable agriculture.

When it comes to making of certain decisions everyday/routine or specific, which often imply planning, programming, selection of the most favorable alternative, financing or realization of business task, it is mostly based on the data analysis. Criteria which are imposed on that occasion are diverse and sometimes mutually opposed. Problems posed to...
In this paper, an application of the Stochastic Mellin Transforms (SMTs) in determination of the probability distribution functions (PDFs) of the Stochastic Volatility (SV) models is proposed. In that aim, three basic SV time series with Gaussian innovations have been considered, and their PDFs were obtained by using the inverse SMT formula.
Cloud technology is a system that enables the use of IT resources more efficiently, simply and cheaply. The cost-effectiveness of applying this technology is reflected in the optimization of operating costs, the optimization of capital investments, as well as the reduction of costs. Electronic education as a system began to "live" in the late 20th...
The modern business environment requires new methodologies for development of information resources of a business systems.

Management approach is essential to all business systems and subsystems, i.e. human resources, if they want to survive, but today all phases of the management process cannot take place without the support of information a...
A number of methods and techniques can be used in the decision making process. The first systems that began to support decision-making, as a separate scientific discipline, were decision
support systems. The goal was to create decision-making elements and, on the basis of this, make a quality choice for admission of candidates/teachers into employm...

Research results are presented in the form...
Virtualization of information resources is a fast growing technology in the business environment. Given technology is the basis for the development of the industrial sector, telecommunications, cloud computing and other socioeconomic structures. This concept could be approximately defined due to virtual systems in the business environment (i.e. vir...
This paper attempts to empirically estimate equilibrium exchange rate level of Serbian dinar. In that purpose reduced form equilibrium real exchange rate approach (ERER) is used, developed by IMF's Consultative Group on Exchange Rate Issues (CGER). The research was made by using ARDL approach in the single-country analysis. It has been started from...
There has been intensive development in telecommunications, financial services, industrial complexes.

The goal of the project is to investigate specific competencies in the public and private sectors of Serbia, identify their weaknesses and propose ways to improve competitiveness and transition from a resource-based economy to one driven by innovation.
In accordance with the development policies of the EU highlighted in the Lisbon Strategy, a conceptual research framework was determined for improving the competitiveness of the public and private sector in Serbia with an emphasis on five key research segments.
The importance of research in this project stems directly from the importance of fulfilling the economic dimension of state competence, that is, the equal inclusion of Serbia in the European and world market of goods and services.
