The technology set involved in the estimation of a multi-output production frontier theoretically implies monotonicity on outputs. This is because an efficient firm cannot reduce the vector of outputs holding the vector of inputs fixed while it still belongs to the frontier. In empirical studies...

This paper studies the technical efficiency of airports in Latin America. The evolution of productive efficiency in the region has seldom been studied, mainly due to lack of publicly available data. Relying on a unique dataset that was obtained through questionnaires distributed to airport...

The main purpose of this paper is to provide an introduction to artificial neural networks (ANNs) and to review their applications in efficiency analysis. Finally, a comparison of efficiency techniques in a non-linear production function is carried out. The results suggest that ANNs are a...

The aim of this paper is to simulate some education policies which would be consistent with different definitions of equality of opportunity (EO). In concrete, we estimate how educational resources should be distributed in order to achieve equality of educational opportunity in the province of...

Most of the literature on the efficiency effects of regulatory reforms ignores the gradual nature of the implementation of these reforms. This article describes a new simple data manipulation that minimizes data requirements to measure econometrically the impact on efficiency of each stage of...

Monte Carlo experimentation is a well-known approach used to test the performance of alternative methodologies under different hypotheses. In the frontier analysis framework, whatever the parametric or non-parametric methods tested, experiments to date have been developed assuming single output...

The principal aim of this paper is to measure the efficiency of international airlines. We obtain measures of technical efficiency from stochastic frontier production functions which have been adjusted to account for environmental influences such as network conditions, geographical factors, etc....
