In this paper we offer a simple exposition of the neoclassical production theoretic foundations of Data Envelopment Analysis. The concepts of technical efficiency (both input- and output-oriented), scale efficiency, and cost efficiency are explained and the corresponding DEA models are described...

If a DEA model has a mix of categorical and continuous variables a standard LP formulation can still be used by entering all combinations of categorical and continuous variables as different types of inputs and/or outputs. Most units will then not have positive levels of all variables. The...

The formulas of cost and allocative efficiencies of decision making units (DMUs) with positive data cannot be used for DMUs with negative data. On the other hand, these formulas are needed to analyze the productivity and performance of DMUs with negative data. To this end, this study introduces...

T his paper consists in measuring the performance of some banks in Tunisia during the year 2004. This purpose we used the Data Envelopment Analysis (DEA) method under a linear programming using GAMS software. Within this analysis, we presented two banking approaches: intermediate and productive;...

The purpose of this chapter is to review dental economics in three major areas: (i) demand for and utilisation of dental care, (ii) productivity, technical efficiency and economies of scale in dental care production, and finally (iii) economic evaluation of dental care procedures and programmes....
