Using a stochastic frontier model and a comprehensive dataset, we study factors that affect corporate efficiency in … efficiency, and (iii) high competition is less conductive to efficiency than moderate or low competition. In terms of ownership …, we find that (iv) efficiency increases when a majority owner must deal with minority shareholders and that (v) domestic …

In this paper we compare two flexible estimators of technical efficiency in a cross-sectional setting: the … nonparametric kernel SFA estimator of Fan, Li and Weersink (1996) to the nonparametric bias corrected DEA estimator of Kneip, Simar … examples. We find that the reliability of efficiency scores critically hinges upon the ratio of the variation in efficiency to …
