Measures for efficiency and eco-efficiency

Comparison between the economic subjects on micro and macro economic levels by a unitary indicator is provided by measuring efficiency as an evaluation of the performance of subjects. For each economic subject technical, allocative, economic, scale efficiencies and eco-efficiency can be computed if all data required are available. This paper attends to examine a method based on linear programming - Data Envelopment Analysis (DEA). Two models for technical efficiency and their derivates to measure other efficiencies are presented and compared in detail - a simple DEA model and an additive DEA model. Finally, theoretical procedures are applied on the forest industry in between the counties of Czech Republic and comparison by measurements of efficiencies is provided
