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

Eder, Andreas - 2021

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...

An analysis of agricultural production in Pakistan : a study based on the asymmetric role of inputs

Iqbal, Naveed; Sial, Maqbool H.; Saleem, Adeel - In: Pakistan journal of applied economics : PJAE 31 (2021) 2, pp. 191-208

Agricultural inputs are peculiar in nature as an asymmetry in their roles can be identified during the production process. These inputs can be grouped into a set of growth inputs or a set of facilitating inputs. The inputs affecting biological or physiological growth from the inside of the plant...

Measuring Productivity Growth and Capacity Utilization in Data Envelopment Analysis : An Application

Sahoo, Biresh - 2012

This article first reviews the well-known nonparametric methods of decomposing productivity growth and finally argue that Färe et al. (1994)’s method of computing productivity growth is superior in spite of the fact that this model model is based on convexity postulate, which assumes away...

Re-Examining Scale Elasticity in DEA

Tone, Kaoru; Sahoo, Biresh - 2012

We propose a new scheme for measuring scale elasticity of production based on a new cost efficiency model developed in Tone (2002). Comparing our model with classical model we establish the superiority of our model over the latter based on the premise that the classical estimates of cost...

Stochastic Nonparametric Envelopment of Data : Combining Virtues of Sfa and DEA in a Unified Framework

Kuosmanen, Timo - 2006

Analysis (SFA) and nonparametric Data Envelopment Analysis (DEA). This paper attempts to combine the virtues of both approaches … nonparametric route of DEA that only imposes free disposability, convexity, and some specification of returns to scale. From the … the data. The resulting function will always take a piece-wise linear form analogous to the DEA frontiers. We discuss the …

Returns to Growth in a Nonparametric DEA Approach

Sahoo, Biresh; Kerstens, Kristiaan; Tone, Kaoru - 2012

In this contribution, first the concept of returns to growth (RTG) of a high-tech firm facing hyper-competition in the new economy is introduced by describing a proportional relationship between growth in inputs and growth in outputs using the growth efficiency (GE) model of Sengupta (2002)....
