Performance of European Airports: Regulation, Ownership and Managerial Efficiency

Barros, Carlos Pestana; Marques, Rui Cunha - ISEG - School of Economics and Management, Department … - 2008

This paper analyzes regulation, ownership and unobserved managerial ability as factors affecting the performance of a representative sample of European airports by means of frontier models. The Alvarez, Arias and Greene (2004) frontier model is used. These airports are ranked according to their...

Technical Efficiency and Heterogeneity of Argentina Pension Funds

Barros, Carlos Pestana; Ferro, Gustavo; Romero, Carlos - ISEG - School of Economics and Management, Department … - 2008

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...

On the Use of Panel Data in Bayesian Stochastic Frontier Models

Fernández, C.; Osiewalski, J.; Steel, M.F.J. - Tilburg University, Center for Economic Research - 1996

We consider a Bayesian analysis of the stochastic frontier model with composed error.Under a commonly used class of (partly) noninformative prior distributions, the existence of the posterior distribution and of posterior moments is examined.Viewing this model as a Normal linear regression model...

Generalized Stochastic Frontier Production Models

Löthgren, Mickael - Economics Institute for Research (SIR), … - 1996

This paper proposes a generalization of the single output stochastic production frontier model. The generalization allows estimation of production frontiers and distance functions (technical efficiency) for multiple output technologies using cross section or panel data on inputs and outputs.
