ANALYSIS OF SELECTED COUNTRIES' TRADE EFFICIENCY BASED ON THE DEA MODELS

Recently, the efficiency of trade companies has been investigated from various aspects. One of them is the measurement of efficiency of trade companies per individual countries by means of Data Envelopment Analysis (DEA). This aspect of research into the efficiency of trade companies is used in this paper. In other words, this paper explores the efficiency of trade companies in the selected countries of the European Union (EU), with a particular reference to Serbia as the EU candidate country, using the DEA approach. The efficiency of trade companies in the selected countries and Serbia differs depending on the applied input- or output-oriented DEA model. As a whole, the efficiency of trade companies in Serbia is satisfactory when compared to the observed countries. This is largely the result of the improved general conditions of business and economy in Serbia lately as well as of the presence of foreign retail sale chains active in the Serbian retail sale market (Delhaise Serbia in particular).
