Environmental performance: an index number approach
2004
Abstract Tyteca [J. Environ. Manage. 46 (1996) 281] reviews the literature on environmental performance indicators. In that paper he calls for an index that simultaneously accounts for resources used, good outputs produced and pollutants or undesirable outputs emitted. Here, we provide a formal index number of environmental performance which can be computed using data envelopment analysis (DEA) techniques. The implicit benchmark is that of finding the highest ratio of good to bad outputs. Our environmental performance index is constructed from distance functions which implies that it satisfies a number of desirable properties. Since the component distance functions require only information …
Measuring well-being in Colombian departments. The role of geography and demography
2021
This paper provides a composite indicator of well-being for the 33 Colombian departments in the year 2016. The indicator is built by adapting the well-known OECD Better Life Index to the regional level, and includes the dimensions of income, health, education, safety, housing, environment, labour market, and civic engagement and governance. As to the methodology, Data Envelopment Analysis and Multi-Criteria Decision-Making techniques are employed, an approach which enables a comparison of well-being across departments and the construction of rankings. The results yield several take-away messages. First, there are substantial disparities in well-being across Colombian departments. Second, de…
Influence of online transparency on efficiency. Analysis of spanish NGDOs
2020
This study examines (a) whether nongovernmental development organizations (NGDOs) disseminate relevant information for their stakeholders through their web pages, information that after being reviewed and evaluated by external organizations such as the Spanish Coordinator of Development NGO or Lealtad Foundation, allowed these NGDOs to obtain a seal of transparency and (b) whether their level of transparency influences efficiency. To determine online transparency, web pages of seal-approved NGDOs were reviewed to assess the availability of relevant information. This paper uses data envelopment analysis to assess the efficiency using an input orientation. To determine the influence of online…
DO LABOUR SOCIETIES PERFORM DIFFERENTLY TO COOPERATIVES? EVIDENCE FROM THE SPANISH BUILDING INDUSTRY
2012
: Labour Societies and Cooperatives are both Social Economy enterprises, but with noticeable differences, some of which are imposed by legislation in Spain. The aim of this paper is to study whether such differences affect their management capacity and, in particular, efficiency. In doing so, Data Envelopment Analysis techniques and the metafrontier approach proposed by O’Donnell et al. (2008) are used on a sample of Spanish Labour Societies and Cooperatives belonging to the building industry. Scores of technical efficiency and metafrontier ratios are computed at firm level and, as a novel contribution to existing literature in this field of research, at input-specific level. The main findi…
Assessing the performance of the Latin American and Caribbean banking industry: Are domestic and foreign banks so different?
2015
AbstractThis paper studies the relative performance of domestic and foreign banks in the Latin American and Caribbean banking industry. Data Envelopment Analysis is used to compute technical efficiency scores for the years 2001 and 2013. Our main contribution is twofold. On the one hand, we assess performance at the level of the management of specific production factors. On the other hand, we distinguish program efficiency from managerial efficiency, which allows us to evaluate whether the differences in technical efficiency between national and foreign banks are due to the use of different technologies (program efficiency) or, conversely, differences in the managerial capacities of manager…
ARE LAC COOPERATIVE AND COMMERCIAL BANKS SO DIFFERENT IN THEIR MANAGEMENT OF NON‐PERFORMING LOANS?
2018
This paper assesses technical efficiency in the management of non‐performing loans (NPLs) in the Latin American and Caribbean (LAC) banking industry. To that end, Data Envelopment Analysis techniques are employed with data from the years 2013 to 2016 on a sample of 307 LAC cooperative and commercial banks. Our main contribution to existing literature is that differences of efficiency between cooperative banks and commercial banks are assessed as the result of the different capacities of their managers – managerial efficiency – and the so‐called programme efficiency, which represents differences in the technology used by these two categories of entities. Our principal result suggests that th…
Is the environmental performance of industrialized countries converging? A ‘SURE’ approach to testing for convergence
2008
In this paper, we test for convergence in the environmental performance of a sample of OECD countries, with data ranging from 1971 to 2002. First, we use Data Envelopment Analysis (DEA) to compute two environmental performance indicators (EPIs) in the production theory framework. Second, we propose the use of a sequential multivariate approach to test for convergence in environmental performance. These tests allow us to reconcile the time series literature with the cross-sectional dimension, which is basic when testing for convergence in regional blocs. The SURE technique is used, which allows for the existence of correlations across the series without imposing a common speed of mean revers…
Economic and environmental performance of wastewater treatment plants: Potential reductions in greenhouse gases emissions
2014
Abstract Sanitation and wastewater treatment are essential for protecting human health and environmental sustainability. Treatment processes are not free of environmental impacts; consequently assessment of the environmental performance of wastewater treatment plants (WWTPs) has gained interest in recent years. Unlike other methods, a direct approach is followed to estimate environmental performance indicators (EPIs) using data envelopment analysis (DEA), i.e. an index of overall performance is directly obtained. The present study represents pioneering work to integrate environmental impacts in the assessment of the efficiency of WWTP estimating pure (PEPI) and mixed (MEPI) environmental pe…
Assessing environmental performance trends in the transport industry: Eco-innovation or catching-up?
2015
Abstract This paper analyses the change in environmental performance that took place in the transport industry of 38 countries between the years 1995 and 2009. Data Envelopment Analysis techniques and directional distance functions are employed to compute Luenberger productivity indicators for the change in environmental performance and its determinants, namely, environmental technical change resulting from eco-innovation and catching-up with best available environmental technologies. Eight air pollutants account for the environmental contaminants from transport activities, and these are aggregated into three main categories of environmental pressures, namely, global warming, tropospheric o…
Ranking farms with a composite indicator of sustainability
2011
The assessment of sustainability at farm level has been growing in popularity over the last few years. This article contributes to this line of research by building up composite indicators for different facets—social, economic, environmental, and global—of farm sustainability using a methodological approach that combines data envelopment analysis (DEA) and multicriteria decision making (MCDM) methods, and assigns common weights to each individual sustainability indicator. This approach is applied to a database of 163 farms located in the Campos County, a region belonging to the dry lands of the Spanish Northern Plateau, using 12 individual indicators of sustainability. Our findings show tha…
