Productive efficiency analysis is a relevant tool that can be used to evaluate differences in efficiency performance between conventional and organic farms. Such study is important for the assessment of the economic viability of these two agricultural systems. While the existing research has...

The present study uses local maximum likelihood (LML) methods recently proposed by Kumbhakar et al. (2007) to assess the technical efficiency of arable crop Kansas farms. LML techniques overcome the most relevant limitations associated to mainstream parametric stochastic frontier models. Results...
