Axiomatic Foundations of Inefficiency Measurement on < input, output > Space

Russell, R. Robert; Schworm, William E. - 2009

We provide an axiomatic foundation for efficiency measurement in the full space, referred to as "graph efficiency" measurement by Färe, Grosskopf, and Lovell [1985]. We posit four types of axioms: indication, monotonicity, independence of units of measurement, and continuity. We analyze six...

Dynamic industry productivity measures : the case of thermal electricity generation by South Korean plants 2001-2008 and in Chinese regions 2000-2014

Førsund, Finn R.; Heshmati, Almas; Wang, Ke - 2018

A framework for applied production theory should focus on the crucial features of the industry to be studied. First of all, to be useful for a dynamic study, a distinction has to be made between the theoretical production possibilities before investment takes place and the actual empirical...

Degree of Scale Economies and Congestion : A Unified DEA Approach

Tone, Kaoru; Sahoo, Biresh - 2012

There are increasing concerns about how increase in congestion can adversely affect output as well as about the relative benefit-cost ratio or return on investment associated with alternative projects or policies to address those problems. Regardless of what policy strategies are used to address...

Scale, Indivisibilities and Production Function in Data Envelopment Analysis

Tone, Kaoru; Sahoo, Biresh - 2012

some valuable progress has been made exploring the economic theory underlying DEA models, these developments have remained … in their infancy and have not found enough application. An attempt is made here to examine the DEA model of efficiency …-stage production processes makes the technology structure non-convex, and therefore, the standard convex DEA production models (e …

Decomposing Capacity Utilization in Data Envelopment Analysis : An Application to Banks in India

Sahoo, Biresh - 2012

This paper briefly reviews the existing methods of capacity utilization in nonparametric framework from economic perspectives, and then suggests an alternative in the light of limitations therein. In the spirit of work by Coelli et al. [Coelli, T.J., Grifell-Tatje, E., Perelman, S., 2002....

Economic perspectives on DEA

Førsund, Finn R. - 2015 - This version April 2015

Research on productive efficiency at the firm level has developed as an important and active strand of research the last decades, both within operations research, management science and economics. However, the interests pursued within the fields have had some differences regarding sound...

Productivity interpretations of the Farrell efficiency measures and the Malmquist index and its decomposition

Førsund, Finn R. - 2015 - This version August 2015

The ratio definition of efficiency has the form of a productivity measure. But the weights are endogenous variables and they do not function as weights in a productivity index proper. It is shown that extended Farrell measures of efficiency can all be given an interpretation as productivity...

Environmental efficiency measurement when producers control pollutants under heterogeneous conditions: a generalization of the materials balance approach

Eder, Andreas - Agricultural Land Markets - Efficiency and Regulation - 2020

This article provides a generalization of the materials balance-based production model introduced by Coelli et al. (2007). Based on this, some new environmental efficiency (EE) measures are presented. The Coelli et al. (2007) EE measure and its extension by Rødseth (2016) produce biased...
