Input-Orientated Data Envelopment Analysis Framework for Measuring and Decomposing Economic,Environmental and Ecological Efficiency: An Application to OECD Agriculture
Abstract This paper presents an input-orientated data envelopment analysis (DEA) frame-work which allows the measurement and decomposition of economic, environmental and ecological efficiency levels in agricultural production across different countries. Economic,environmental and ecological optimisations search for optimal input combinations that mini-mise total costs, total amount of nutrients, and total amount of cumulative exergy contained in inputs respectively. The application of the framework to an agricultural dataset of 30 OECD countries revealed that (i) there was significant scope to make their agricultural production systems more environmentally and ecologically sustainable; (ii) the improvement in the envi-ronmental and ecological sustainability could be achieved by being more technically efficient and, even more significantly, by changing the input combinations; (iii) the rankings of sus-tainability varied significantly across OECD countries within frontier-based environmental
and ecological efficiency measures and between frontier-based measures and indicators.
