This paper is purposeful towards assessing the significance, state and development of the third sector in Bulgaria. Its first part deals with the theoretical background and specific characteristics of the sector that distinguish and define it as a successful way whereby social problems are...

The main aim of this paper is to compare two alternative methods for estimating frontier functions and measuring efficiency in production. The application of Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) to the same data panel provides insights in estimating technical...

Two alternative methodological approaches for evaluation of the technical efficiency are compared: the Data Envelopment Analysis – DEA, using linear programming techniques and the Stochastic Frontier Analysis – SFA, being a parametric, econometric approach. The study is based on data on 130...

Early microeconomic theory established its framework under the assumption that producers’ behaviour is optimal towards input allocation and output level. Since Debreu and Farrell this basic neoclassical approach has been extended, allowing for producers’ decisions to diverge from the optimum...

The interest in creating a base-line for development patterns of clusters and clusters' specific characteristics in rural areas is particularly imposed by certain problems, which manifest themselves in similar degrees and provide a generic pattern in different regions and countries, e.g....
