A competitive and well-functioning market is imperative for the efficiency of the economy. First, competitive markets help correct distorsions in the structure of production and thus raise productivity levels, and secondly, stronger competition provides an increased incentive for producers in the form of lower prices, higher quality and increased variety. Competition policy deals with the restriction of all non-economic behavior entities that cause market distorsions. The paper provides general features of the European Union competition policy, as well as its historical development, basic elements and methodological framework. Further, this paper provides reforms, tendencies in development and examples from the jurisprudence of the EU competition policy, with a special review of article 81 (prohibition of the restrictive agreements, cartels) and article 82 (prohibition of abuse market dominance) of the EC Treaty.Key Words: Competition policy, European Union, restrictive agreements.

The aim of this paper is to analyse and estimate the efficiency of health information systems in the provision of health care services. The evaluation of health information systems is conducted in the case of three most widely used softwares in the electronic health care. This evaluation is based on multi-criteria analysis of the health information systems efficiency using the AHP-TOPSIS method. This method, based on common attributes and their respective values for all three software solutions, individually determines the best rated software solution. Top rated software solution of electronic health care is not necessarily the best for the implementation and development, given the fact that each health care organisation has its own characteristics. Functional and evolutionary-minded hardware and software applicative infrastructure contributes to the consistency of electronic health concept that all system users provides a comfortable software solutions, which ultimately leads to the timely and quick medical services in real time.

The aim of the research is to classify the European Union (EU) countries based on the progress in the economic performance of agriculture. The originality of the paper stems from the fact that a new set of indicators (in relative form) was used to identify the clusters. The following indicators are used to assess the economic performance of the EU agricultural sector (by cluster analysis) for two periods (2015–2017 and 2018–2020): total labor force input, real income of factors in agriculture per annual work unit, total agricultural output, gross value added of the agricultural industry, and animal output. The study confirmed that EU countries, according to changes in agricultural performance, differ significantly. They were grouped into four relatively homogeneous clusters according to their similarity, with a clear geographical dispersion for both analyzed periods. Identifying development disparities between EU countries can be useful in future redesigns of the Common Agricultural Policy measures in terms of increased support to certain members. ; Celem badań jest klasyfikacja krajów Unii Europejskiej (UE) na podstawie postępu w wynikach ekonomicznych w rolnictwie. Oryginalność artykułu wynika z faktu, że do identyfikacji klastrów zastosowano nowy zestaw wskaźników (w postaci względnej). Do oceny wyników ekonomicznych sektora rolnego UE (poprzez analizę klastrów) dla dwóch okresów (2015–2017 i 2018–2020) stosuje się następujące wskaźniki: całkowity nakład siły roboczej, rzeczywisty dochód czynników w rolnictwie na roczną jednostkę pracy, produkcja rolna ogółem, wartość dodana brutto przemysłu rolnego oraz produkcja zwierzęca. Badanie potwierdziło, że kraje UE znacznie się różnią pod względem zmian wyników rolniczych. Zostały one pogrupowane w cztery stosunkowo jednorodne klastry według podobieństwa, z wyraźnym rozproszeniem geograficznym dla obu analizowanych okresów. Identyfikacja dysproporcji rozwojowych pomiędzy krajami UE może być przydatna w przyszłych przekształceniach środków wspólnej polityki rolnej pod kątem zwiększonego wsparcia dla niektórych członków.

The aim of the research is to examine the degree of competitiveness of the agri-food sector of the Republic of Serbia on the market of the European Union (EU) countries, as the most significant export market. Two partial indices were used in the analysis: the net trade index (NTI) and the Grubel-Lloyd index (GLI). In addition to these indicators, unit export and import price analysis was also used to obtain data on the type of competitiveness achieved by the divisions of the agri-food sector. The results show that the cereals division makes the highest contribution to reducing the existing trade deficit, while the high values of the GLI reflect a high degree of integration with this market. The agri-food sector shows dominant price competitiveness in terms of the share of such divisions in total exports to the EU. The results will include recommendations for improving the structure of exports by focusing on specific divisions.
