This paper focuses on nonparametric efficiency analysis based on robust estimation of partial frontiers in a complete multivariate setup (multiple inputs and multiple outputs). It introduces a-quantile efficiency scores. A nonparametric estimator is proposed achieving strong consistency and asymptotic normality. Then if a increases to one as a function of the sample size we recover the properties of the FDH estimator. But our estimator is more robust to the perturbations in data, since it… CONTINUE READING
