It has often been observed in the literature that non-parametric approaches to the estimation of production frontiers are hardly robust in the presence of outliers. This paper proposes a class of robust frontier estimators based upon extreme value theory. The nature of the proposed method is parametric and also allows to ascertain the presence of outliers in the observed production set.
