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 aim of the present paper is to examine the observed differences in Students' test performance across public and private-voucher schools in Spain. For this purpose, we explicitly consider that education is a multi-input multi-output production process subject to inefficient behaviors, which...

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...
