The new model of agricultural policy in Europe, applied through the rural development programs (RDPs), has been considered most appropriate for the case of Greece, given the structural problems of this country?s farm sector (including the high proportion of mountainous, less favoured areas in...

This paper provides empirical evidence of changes in the productivities of manufacturing firms in Indonesia over time, in the form of total factor productivity (TFP), from 1990 to 2010 with and without considering carbon dioxide (CO2) emissions. Employing cleaned and balanced panel datasets for...

This paper analyzes productivity with a directional distance function model by investigating convexity and non-convexity in the Chinese banking sector. Two primary findings are summarized. First, there is a distinct change in productivity between large versus small banks and public versus...

This article analyzes the sources of bank efficiency in Colombia over the period 2000-2011. To perform this research, the authors propose a score of bank efficiency using the directional distance function, which was estimated using data envelopment analysis. Additionally, they use an ordered...

This paper addresses the question how team production promotes efficiency of a firm when some inputs can be rewarded on the basis of outputs but some cannot because they are shared among outputs and non-separable. A multi-activity DEA model with variable returns to scale is proposed to provide...

This study proposes an alternative methodology for measuring environmentally sensitive productivity growth. The rationale of this methodology is to consider the features of technology appropriately by excluding a spurious technical regress based on the macroeconomic perspective. In order to...

We conduct an empirical analysis of the technical efficiency of cars sold in Germany in 2010. The analysis is performed using traditional data envelopment analysis (DEA) as well as directional distance functions (DDF). The approach of DDF allows incorporating the reduction of carbon dioxide...

Aim: A problem in efficiency and productivity studies in banking is that some of the input and output prices used in the estimation of cost, revenue and profit functions are proxies of questionable quality with obvious impact on the reliability of performance measures. We address this issue...

This paper develops a new factor-analysis-based (FAB) approach for choosing the optimal direction in a directional distance function (DDF) analysis. It has the combined merits of factor analysis and slacks-based measure (SBM) and incorporates the relative ease with which various input-output...
