The last 10 years in the area of efficiency analysis have been characteristic of development of new models and methods as well as a big number of empirical applications in various sectors of economy. Empirical applications, which is also applicable to the sector of agriculture, are based either on radial or additive models. Due to their nature, radial models usually overstate efficiency when nonzero slacks are present because they do not consider non-radial inefficiency of the slacks. Unlike radial models, additive models take into account all sources of inefficiency, i.e. radial and non-radial, however, they do not directly *provide efficiency measure. The work compares the above-mentioned models with the so called global efficiency measures, which are capable of taking into consideration all sources of inefficiency, thus enabling to calculate directly efficiency measure. The global efficiency measure derived from Russell Graph Measure of Technical Efficiency and Enhanced Russell Graph Measure of Technical Efficiency is presented and applied.
