Improving agricultural economic efficiency in Brazil. Author(s): SOUZA, G. da S. e; GOMES, E. G. In this article, we use Brazilian census data (1995/1996 and 2006) to model agricultural production at the state level in Brazil. Cost-efficiency measurements are computed using data envelopment analy... ... Repository: BDPA Publication year: 2015
Efficiency and sustainability assessment for a group of farmers in the Brazilian Amazon. Author(s): GOMES, E. G.; MELLO, J. C. C. B. S. de; SOUZA, G. da S. e; MEZA, L. A.; MANGABEIRA, J. A. de C. The aim of this paper is to use DEA models to evaluate sustainability in agriculture. Several variables are taken into account and the resulting efficiency is measured by comparison. The performance o... ... Repository: BDPA Publication year: 2009
Potential improvement of agricultural output for major producers based on DEA efficiency measurements. Author(s): SOUZA, G. da S. e; MOREIRA, T. B. S.; GOMES, E. G. In this article we perform production efficiency analysis for the 40 countries with largest value added by agricultural sector in 2005. Under the assumption of a nonparametric frontier and production... ... Repository: BDPA Publication year: 2011
A parametric approach for evaluating the technical efficiency of the brazilian agricultural sector. Author(s): SOUZA, G. da S. e; GOMES, E. G.; GAZZOLA, R.; WANDER, A. E.; SOUZA, R. da S. In this study we assessed the technical efficiency of the 27 Brazilian states in the years 1995/96 and 2006.
