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...

This study examined whether the cost efficiency measures were invariant to the choice of parametric and nonparametric methods for a sample of 183 wheat farms. In the deterministic nonparametric method, the economic, scale and overall efficiency results were invariant to the dimensionality. Only...
