The statistical properties of the efficiency estimators based on Data Envelopment Analysis (DEA) are largely unknown. Recent work by Simar et al. and Banker has shown the consistency of the DEA estimators under specific assumptions, and Banker proposes asymptotic tests of whether two subsamples...

Crisp input and output data are fundamentally indispensable in traditional data envelopment analysis (DEA). However, the real-world problems often deal with imprecise or ambiguous data. In this paper, we propose a novel robust data envelopment model (RDEA) to investigate the efficiencies of...

Анализ оболочки данных (DEA) - это относительно новая методика измерения технической эффективности. Если сформулировать техническую эффективность определенного...

In the paper we propose an to evaluation of the environmental effects of consumption activities. The approach consists of two steps, namely (1) assignment of environmental effects to consumption activities, for which we propose to use the methods of (multidimensional) cost sharing, and (2) a...

Environmental cost-benefit analysis (ECBA) refers to social evaluation of investment projects and policies that involve significant environmental impacts. Valuation of the environmental impacts in monetary terms forms one of the critical steps in ECBA. We propose a new approach for environmental...

We investigate the consistency of efficiency scores derived with two competing frontier methods in the financial economics literature: Stochastic Frontier and Data Envelopment Analysis. We sample 34,192 observations for all German universal banks and analyze whether efficiency measures yield...

"Дискуссионные материалы" анализируют изменение эффективности и общей продуктивности факторов (англ. total factor productivity, TFP) крупных сельскохозяйственных...

Dieses Discussion Paper beschäftigt sich mit der Analyse der technischen und Skaleneffizienz russischer Agrarunternehmen im Transformationsprozess. Insbesondere wird hierbei der Einfluss der Faktoren Betriebsgröße, Rechtsform und Spezialisierung auf die Effizienz untersucht. Um die...

A nonparametric Data Envelopment Analysis (DEA) is performed on hospitals in the federal state of Saxony (Germany) and in Switzerland. This study is of interest from three points of view. First, contrary to most existing work, patient days are not treated as an output but as an input. Second,...

Economic efficiency – understood in terms of jurisdictions providing a maximum amount of output for a given level of inputs – is one potential means to evaluate public policies. Various approaches, however, co-exist to measure the (technical) efficiency of organizations. Given that these...
