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...

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....

Das Hauptziel des vorliegenden "Discussions Paper" ist es, den russischsprachigen Leser mit den theoretischen Grundlagen der Produktivitäts- und Effizienzanalyse der landwirtschaftlichen Unternehmen vertraut zu machen. In der russischsprachigen Literatur wurden und werden bis zu heutigem...

The aim of this paper is to assess whether bancassurance firms outperform other life insurance companies. Cost and profit efficiency are estimated using a stochastic frontier analysis and including several firm‐specific factors to overcome possible sample heterogeneity. On the cost side, we...

In the presence of (at least locally) increasing returns to scale tech- nologies, the paper asks the question: does there exist an economic system which implements Pareto efficient allocations and respects the voluntary participation principle? To answer this question, the paper formulates an...

Using data from the EPA's EGRID and Clean Air Markets databases, we investigate the energy (technical) and emissions (ecological) efficiencies of 437 of the largest U.S. electricity generators. We focus on fossil-fuel based electricity generating plants because of their significant impact on...

This paper investigates the dynamic and the determinants of banking industry efficiency in Latin America. Allocative, technical, pure technical and scale efficiencies are calculated and analyzed in each country. We find that Latin American bank managers have been using resources efficiently, but...

Cotton is one of the most important sector for developing countries, especially in Pakistan. In this paper the linear model based on data of 2004 to 2006 cotton yield is developed to maximize the cotton production of Pakistan. In this model variables are allowed to randomly vary with in interval...
