Abstract
> In this paper, we asses the efficiency of Brazilian airports, based on Data Envelopment Analysis (DEA). Although previous studies applied DEA to Brazilian airports, herein we consider DEA´s homogeneity assumption, according to which units are assumed to operate in similar environments. As airport environment differs significantly throughout the country, we limit our analysis to six central airports. Still, our results are valuable nationwide, because these airports handle half of all flights departing from Brazil. As classic DEA is not recommended for small data sets, we use Multiple Criteria DEA, which has more discriminatory power. In our study, we found that only two airports in the State of Sao Paulo are efficient, whereas the other central airports are under-utilized, with an efficiency score of less than 50%. Results found in this study could serve as an important tool for public politics, as well as for private decisions in the airport sector. KEYWORDS. Airport efficiency; central airports; Brazilian air transport; Multiple Criteria Data Envelopment Analysis. MSC: 90B06
