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 period 1987 to 2005 and homogenous and heterogeneous...

In this paper, the innovative random stochastic frontier model is used to estimate the technical efficiency of UK airports. These airports are ranked according to their total productivity for the period 2000-2005 and homogenous and heterogeneous variables in the cost function are disentangled,...

This paper examines the technical efficiency of Argentinean pension funds management companies using a random stochastic frontier model to rank the pension funds management companies, taking into account heterogeneity in the data. The empirical findings reveal that efficiency measures have a...

In this paper we measure and analyse expenditure efficiency of Portuguese local governments using a non-parametric technique for production frontier estimation known as Free Disposal Hull. We first construct an index of municipal performance and then compute input and output efficiency scores...
