Distributional forms in stochastic frontier analysis

Stead, Alexander D.; Wheat, Phill; Greene, William H. - In: The Palgrave handbook of economic performance analysis, (pp. 225-274). 2019

This chapter is a survey of developments in stochastic frontier modelling. The literature on stochastic frontiers has grown substantially in the 42 years since the seminal work by Aigner et al. (J. Econom 6 (1): 21–37, 1977). There exist many surveys of this literature that cover a broad range...

Understanding prediction intervals for firm specific inefficiency scores from parametric stochastic frontier models

Wheat, Phill; Greene, William; Smith, Andrew - In: Journal of Productivity Analysis 42 (2014) 1, pp. 55-65

This paper makes two important contributions to the literature on prediction intervals for firm specific inefficiency estimates in cross sectional SFA models. Firstly, the existing intervals in the literature do not correspond to the minimum width intervals and in this paper we discuss how to...
