THE INFLUENCE OF THE COMPETITION POLICY ON STATE AID AND PUBLIC SECTOR WITHIN THE EUROPEAN UNION SINGLE MARKET

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

Circular economy indicators can be used for ranking countries and their hierarchical clustering. It shows the differences and similarities in the progress between individual countries, made toward the realization of the principles of the circular economy (CE). CE is a modern concept and the aspiration to preserve resources and protect the environment. The paper presents a cluster analysis at the level of the European Union (EU27) countries, based on the data of CE composite indicators, which is managed by the statistical office of the European Union (Eurostat). SPSS IBM 26.0 statistics software was used for cluster analysis, while the ANOVA method was applied to check the statistical significance of the obtained results. The most important results achieved in the paper are the classification into 6 clusters within the EU27 countries, with similar policies in the area of the circular economy. The best-ranked cluster is cluster 6 which consists of only 1 country, the Netherlands, the European leader in the circular economy. Accordingly, this paper aims to determine the similarities and differences between the EU member states in the implementation of circular economy postulates by dividing them into clusters. In this way, the highest mean values of the indicators within the cluster will be determined, and thus the circular economy model that other clusters should follow.Indikatoricirkularne ekonomije mogu se primeniti za rangiranje zemalja, kao i njihovo hijerargijsko grupisanje. To pokazuje razlike i sličnosti u napretku između pojedinih zemalja, ostvarenog ka realizaciji principa cirkularne ekonomije.

Economic Performance of Agriculture in the European Union Countries

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
