Abstract

Data Envelopment Analysis (DEA) is a well-established relative efficiency measurement
technique, which has been widely applied to evaluate the technical efficiency of agricultural
units in different countries by focusing on different aspects of agricultural production. This
research deals with the evaluation of efficiency through DEA in non-homogeneous
agricultural production, where units produce a wide range of different outputs. The
objectives are threefold. Firstly, we propose a novel methodological approach of integrating
the production trade-offs concept of DEA into non-homogeneous agricultural efficiency
evaluation to prevent the overstatement of the efficiency of specialist farms and overcome
the issue of insufficient discrimination due to large number of outputs in the models.
Secondly, we aim to integrate this methodological perspective to the theory of elasticity
measurement on DEA frontiers. The efficient frontiers of DEA are not defined in functional
forms as in the classical economic theory, therefore obtaining elasticity measures on them
require different considerations. We introduce the production trade-offs to the elasticity
measurement and derive the necessary models to calculate the elasticities of response in the
presence of production trade-offs. As a third objective, before moving to the introduction of
the trade-offs in elasticity measurement, for theoretical completeness, we first consider the
elasticity measurement on DEA frontiers of constant returns-to-scale (CRS) technologies.
Our proposed methodology and all the developed elasticity theory are illustrated in a real
world case of Turkish agricultural sectors. We provide extensive empirical applications
covering all the proposed theory and methodology. Among the results of this research, we
provide an elasticity measurement framework, which enables us to calculate elasticities of
response measures in both VRS and CRS technologies, with or without production tradeoffs
included. We observe that the integration of production trade-offs provide better
discrimination of efficiency scores compared to the models without trade-offs included. We
also investigate how changing production trade-offs affect the efficiency and elasticity
measures of the evaluated units.
