In this paper, the two-stage procedure of Simar and Wilson (2007) is used to estimate the technical efficiency of Argentina’s airports from 2003-2007, a period of intense economic crisis, during which the traffic fell by 50%. In the first stage, the airports’ relative technical efficiency is estimated with DEA (data envelopment analysis) to establish which airports perform most efficiently. In the second stage, the Simar and Wilson (2007) procedure is used to bootstrap the DEA scores with a truncated regression. Economic implications arising from the study are also considered.
