Measuring Sustainability Efficiency Using a Two-Stage Data Envelopment Analysis Approach
Halkos, G. E.; Tzeremes, N. G.; Kourtzidis, S. A. (2015)In this article, we apply an additive two-stage data envelopment analysis estimator on a panel of 20 countries with advanced economies for the time period 1990-2011 in order to create a composite sustainability efficiency ... -
Regional sustainability efficiency index in Europe: an additive two-stage DEA approach
Halkos, G. E.; Tzeremes, N. G.; Kourtzidis, S. A. (2015)In this paper we apply a relational additive two-stage data envelopment analysis model in order to create sustainability efficiency indices for European regions. The sustainability efficiency indices are decomposed into ... -
A unified classification of two-stage DEA models
Halkos, G. E.; Tzeremes, N. G.; Kourtzidis, S. A. (2014)Standard Data Envelopment Analysis (DEA) is used to evaluate the efficiency of Decision Making Units (DMUs) and treats its internal structures as a "black box". The aim of this paper is twofold. The first task is to survey ... -
Weight assurance region in two-stage additive efficiency decomposition DEA model: an application to school data
Halkos, G. E.; Tzeremes, N. G.; Kourtzidis, S. A. (2015)In this paper we use the additive efficiency decomposition approach in two-stage data envelopment analysis. Initially, we evaluate the variable returns to scale version and face a structural difficulty of the model. In an ...
