Zusammenfassung

We study DEA efficiencies of 47 Spanish airports over the period 2009-2013 under a variety of input/outputspecifications. 186 input/output specifications are estimated using DEA. The results are analysed using the tools ofmultivariate statistical analysis, in particular the Individual Differences Scaling model of Caroll and Chang. Thismodel reveals what has remained invariant over the period, what are the most salient characteristics of airportefficiency, and how these characteristics have changed in importance during the crisis period. Given the largedifferences in size between the airports we use the Variable Returns to Scale approach. Since it is a characteristicof economic crisis that some capacity remains idle, we use the output oriented form of DEA. The results reveal animportant drop in efficiency between 2009 and 2010, followed by a period of slow recovery.
