Asymptotics and Consistent Bootstraps for DEA Estimators in Non-parametric Frontier Models
Kneip, Alois; Simar, Léopold; Wilson, Paul W. - 2006
Non-parametric data envelopment analysis (DEA) estimators based on linear programming methods have been widely applied … inference doubtful. This paper derives the asymptotic distribution of DEA estimators under variable returns-to-scale. This … well as smoothing of the DEA frontier estimate. Both bootstrap procedures allow for dependence of the inefficiency process …
