Abstract

Data Envelopment Analysis (DEA) profit ratios and technical efficiency measures require separate treatment as proved in newly developed theory of Thompson and Thrall. This point is illustrated here by analysis of an example problem; it shows that DEA technical efficiency does not necessarily imply a DEA maximum profit ratio; and, vice versa, a DEA maximum profit ratio does not necessarily imply DEA technical efficiency. The essence of the mathematical framework underlying this argument is provided. Application of the concepts to Illinois coal mining data (previously reported) lends support to the need for separate treatment of DEA technical efficiency and DEA profit ratios.

A literature review of economic efficiency assessments using Data Envelopment Analysis
2024, European Journal of Operational Research
This paper presents a literature review on Data Envelopment Analysis assessments of economic efficiency, covering methodological developments and empirical applications. We review the seminal models for economic efficiency measurement, involving the optimization of cost, revenue, and profit. The applications of the different modelling approaches are also discussed. Based on a content analysis of papers published between 1978 and 2020 in various sectors, the main areas of study are identified, and the pathways of research developments are discussed. Most studies are based on disaggregated quantity and price data. In addition, the use of panel data is prevalent compared to cross-sectional studies. There is a preponderance of input-oriented studies focused on cost efficiency rather than revenue or profit efficiency. Informed by the historical evolution of economic efficiency assessments portrayed in this review, we suggest directions for future developments.
Ratio-based data envelopment analysis: An interactive approach to identify benchmark
2022, Results in Control and Optimization
In the real world we are confronted with many cases where the ratio of input/output data is so important for managers, so in this regard we cannot use traditional Data Envelopment Analysis (DEA) models to evaluate the efficiency of decision-making units (DMU) and we should use DEA models based on ratio data. To get the corresponding benchmark for each inefficient decision-making unit, we need to reduce and increase the inputs and outputs, respectively, and get the unified projection of the decision maker unit on the efficiency frontier. In this paper we present a multi-objective linear programming (MOLP) model for evaluating efficiency based on defining the production possibility set in the presence of ratio data and to get the corresponding benchmark to each decision-making unit DMU. We use the Zionts and Wallenius (Z–W) interactive method to solve the MOLP model presented. Using the target setting by manager among the solutions resulting from the MOLP problem, we choose best solution according to the managers’ preferences as benchmark and at the end we present the results of the research.
Units of measurement and directional distance functions with optimal endogenous directions in data envelopment analysis
2020, European Journal of Operational Research
The virtual profit efficiency model is sensitive with respect to units of measurement as is the related directional distance function. It is shown that the model can be made invariant with respect to changes in units of measurement in a similar vein as the directional distance function. The geometric interpretation of changes in units of measurement in input output space is uncovered and shown to be similar to the interpretation of the underlying base model. A weighted virtual profit efficiency model with focus on input contractions and output expansions in selected dimensions is developed, and differences and similarities between the working of the weighted versus the unweighted base model are uncovered. It is demonstrated how to incorporate Assurance Regions and Cone Ratios in the virtual profit efficiency model.
Industrial policy, energy and environment efficiency: Evidence from Chinese firm-level data
2020, Journal of Environmental Management
Based on a unique micro-level dataset of 30,689 mining enterprises from 2008 to 2011, this paper uses the non-radial directional distance function (NDDF) to calculate the unified efficiency index (UEI) and energy-environmental performance index (EEI) for China's mining enterprises. The double bootstrap method is then used to test how tax incentive policies affect the UEI and EEI of China's mining enterprises. The results show that: (1) the UEI and EEI of Chinese mining enterprises first decreased and then increased over the sample period; overall, Chinese mining enterprises had low energy and environmental efficiency, especially the coal mining enterprises, private mining enterprises and mining enterprises in the central and western regions. (2) Tax incentives positively affect the energy and environmental efficiency of mining enterprises, especially the efficiency of coal mining enterprises, non-state-owned mining enterprises and mining enterprises in the central and western regions. Our results remain robust after using the propensity score matching estimator (PSM). (3) There is a positive feedback between tax incentives and energy and environmental efficiency, more efficient mining enterprises receive more government incentives. Further analysis shows that although tax incentives do not reduce the total energy consumption of enterprises, reducing the energy consumption of enterprises can improve their UEI and EEI. In addition, R&D investment, profitability and resource taxes all contribute to improving the UEI and EEI of mining enterprises.
Production efficiency and geographical location of Chinese coal enterprises - undesirable EBM DEA
2019, Resources Policy
China's economic and social development is expected to depend on coal as a primary energy source for at least the next two decades until there is a significant rise in the availability of clean energy. As China's main source of energy, the relatively low coal production level has been a key reason for the low overall energy efficiency. Further, the implementation of environmental protection policies has also constrained the use coal as an energy source in heavily polluting industries. Therefore, research into coal efficiency is necessary to ensure the future of coal energy. This paper used an EBM evaluation model to analyze the production efficiency of coal enterprises at the micro level, and then analyzed the efficiency of coal enterprise input and output factors using coal mine data from 2015-2017f sources from a large Chinese coal company. It was found that the inputs and output inefficiencies were mainly affected by radial inefficiencies, that most mines needed significant improvements, that the mining areas closer to the city center needed significantly greater improvements, and that mines further from the city were generally more efficient.
Reallocation of resources in multidivisional firms: A nonparametric approach
2019, International Journal of Production Economics
Recently, increasing research attention has been paid to studying and modelling the efficiency behaviour of multidivisional firms. In this paper, we propose a simple and intuitive nonparametric approach for cost minimising in multidivisional firms when resources can be reallocated across firms and/or divisions. In particular, we consider that resource reallocation occurs through the price system. One distinguishing feature of our approach is that no price information is required to evaluate cost efficiency. This feature clearly increases the practical usefulness of our methodology given that prices are generally unknown when resource reallocation is possible. We consider various extensions of our framework, present a simulation, and apply our methodology to the Chinese manufacturing sector using a firm-level dataset.
