Centralized resource allocations with adjustment costs and a nonconvex production technology
Athletics performance in Olympic Games
This paper presents a Network Data Envelopment Analysis (NDEA) model to evaluate the performance of countries in Olympic athletics, distinguishing between qualification and participation stages. Unlike traditional methods, it includes all nations, regardless of medal wins, ensuring a more inclusive assessment. The model addresses the Constant-Sum-of-Outputs (CSO) constraint by scaling results relative to total points available in each Games. The …
Social Welfare Preferences and Sustainable Development Goals. A Multivariate Analysis Approach
This paper explores the interrelationship between individual social welfare preferences (SWPs) and sustainable development goals (SDGs). Social welfare preferences are measured through the World Values Survey. To illustrate the proposed approach, we focus on SDG 6, which aims to ensure clean water and sanitation for all. More specifically, SDG progress is measured through SDG Target 6.4. The methodology employed is mainly based on Discriminant An…
Forest efficiency assessment and prediction using dynamic DEA and machine learning
Assessing sustainability indicators using inverse integer-valued data envelopment analysis with undesirable outputs
A metafrontier network DEA approach for water usage efficiency assessment in the light of SDG target 6.4
The efficient use of water must be enhanced and promoted to achieve the Sustainable Development Goal (SDG) 6. Thus, to contribute to the achievement of SDG Target 6.4 and close a research gap in SDGs’ progress, this paper carries out a water usage efficiency analysis of 126 countries leveraging the AQUASTAT database maintained by the Food and Agriculture Organization of the United Nations (FAO), providing information that can help assess and prom…
A pre-pandemic Data Envelopment Analysis of the sustainability efficiency of tourism in EU-27 countries
This paper evaluates the sustainability efficiency of tourism across 27 countries in the European Union for the years 2015–2019. The proposed approach is based on the data analysis envelopment (DEA) methodology and uses different economic, social and environmental indicators. A non-oriented, slacks-based inefficiency (SBI) model is proposed. Efficiency scores and targets for each country in each year are computed and discussed. Given the relative…
Efficiency Analysis of the European Food Banks
Hundreds of thousands of people in Europe are daily receiving food, thanks to local food banks, run basically by volunteers who collect donations and distribute them to organizations. In this paper, data from a sample of food banks working in 13 European countries are analysed using Data Envelopment Analysis (DEA), trying to learn about their profiles and find some clues about the efficiency of their operations, comparing them according to variab…
Dimensionality Reduction and Visualization of the Environmental Impacts of Domestic Appliances
There is an increasing worldwide concern about the problem of dealing with the waste electrical and electronic equipment (WEEE), given the high volume of appliances that are disposed of every day. In this article, an environmental evaluation of WEEE is performed that combines life cycle assessment (LCA) methodology and multivariate statistical techniques. Because LCA handles a large number of data in its different phases, when one is trying to un…
