The idea is to deliver a tailored seminar, to show different results (papers) depending on the needs of the audience and experience in DEA or/and SFA. The seminar will address alternative methodological approaches to the conventional models commonly classified as non-parametric and parametric methods. Several approaches are used in order to overcome specific limitations that the methodologies present compared to the other. Within the non-parametric techniques, Data Envelopment Analysis (DEA) is used and as parametric models, Stochastic Frontier Analysis (SFA). The literature shows a lack of usage of SFA in empirical studies compared to DEA. The conventional DEA models present some limitations; for example, they tend not to incorporate time-related effects. Empirical examples of both methodologies are drawn based on the application to the Spanish airports with the aim to estimate and to confirm the consistency of the Spanish airports’ efficiency across time.
