“…The analysis of productivity and technical efficiency of airports is a well-established research field (see, Pels et al, 2001Pels et al, , 2003Yoshida, 2004;Yoshida and Fujimoto, 2004;Barros et al, 2010aBarros et al, , 2010b. Several techniques have been proposed in the literature to measure productivity and technical efficiency, such as the non-parametric data envelopment analysis (DEA) (see Lall, 1997, 2001;Parker, 1999;Murillo-Melchor, 1999;Adler and Berechman, 2001;Fernandes and Pacheco, 2002;Sarkis, 2000;Sarkis and Talluri, 2004;Yoshida and Fujimoto, 2004) and the parametric stochastic frontier model (see Pels et al, 2001Pels et al, , 2003.…”
