This paper evaluates the production activities of Japanese airports by using a finite mixture model that allows … different groups of Japanese airports but also permits the analysis of their production efficiency. The main result is that … there are two groups of Japanese airports, both following completely different "technologies" to obtain passengers and cargo …

In this paper, the random stochastic frontier model is used to estimate the technical efficiency of Japanese airports … taking into regulation and heterogeneity in the variables. The airports are ranked according to their productivity for the …
