The purpose of this paper is to emphasize the importance of intellectual capital (IC) undisclosed on the assets side on the balance sheet of knowledge enterprises. This capital is very relevant, and mana-gers need to have information about it in order to facilitate effective IC management process. The issue of IC performance measurement has been a matter of growing importance in both academic community and managerial practices for the past two decades. Based on the previous ideas put forward in the literature of knowledge management and IC management, this paper suggests a new methodological framework for overcoming the problem of IC performance measurement in knowledge enterprises. Efficiency of Intellectual Capital (EIC) methodological framework offers practical solutions for measuring the efficiency of total enterprises' IC, as well as the efficiency in the use of all IC components. The EIC framework connects financial accounting valuation and market valuation.

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.

The purpose of this research is analysis and forecasting of the most important trends on the international wine market, as well as identifying opportunities for wine export from Serbia. The aim of the research is to analyse the movement of the wine production and trade on the international market by applying the appropriate methodology. The paper is structured in the following segments: 1) examining the impact of number of vines and yields per vine on the acheved volume of grape production in the Republic of Serbia in the observed period; 2) examining the competitive position of the Republic of Serbia on the international wine market; and 3) analysis of the value and structure of foreign trade of wine between the Republic of Serbia and other countries. Comparative analysis, correlation analysis and regression analysis are used in the paper. The results of this paper indicate: 1) higher impact of yields per vine on the volume of grape production in relation to the impact of the number of vines on the volume of grape production; 2) increasing deficit of foreign trade of wine between Serbia and other world countries; and 3) that Serbia reduced coverage of import of wine by export of wine in the observed period.
