In this paper, the two innovative non-parametric models, the Luenberger productivity model and the Luenberger-Hicks-Moorsteen productivity indicator, are used to estimate the productivity of UK airports. The airports are ranked according to their total productivity over ten years showing that...

In this paper, the random stochastic frontier model is used to estimate the technical efficiency of Japanese steam power generation companies taking into regulation and pollution. The companies are ranked according to their productivity for the period 1976-2003 and homogenous and heterogeneous...

This paper evaluates the production activities of Japanese airports by using a finite mixture model that allows controlling for unobserved heterogeneity. In doing so, a stochastic frontier latent class model, which allows the existence of different technologies, is adopted to estimate production...

In this paper, the random stochastic frontier model is used to estimate the technical efficiency of Japanese airports, with regulation and heterogeneity included in the variables. The airports are ranked according to their productivity for the period 1987–2005 and homogeneous and heterogeneous...
