Description
Summary: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 En este documento, evaluamos la eficiencia de los aeropuertos brasilenos, segun el Data Envelopment Analysis (DEA). Aunque estudios previos aplicaron DEA a aeropuertos brasilenos, aqui consideramos el supuesto de homogeneidad de DEA, segun el cual se supone que las unidades operan en entornos similares. Como el sitio aeroportuario difiere significativamente en todo el pais, limitamos nuestro análisis a seis aeropuertos centrales. Aun asi, nuestros resultados son valiosos en todo el pais, porque estos aeropuertos manejan la mitad de todos los vuelos que salen de Brasil. Como la DEA clásica no se recomienda para conjuntos de datos pequenos, utilizamos la DEA de Multiple Criteria DEA (MCDEA), que tiene más poder discriminatorio. En nuestro estudio, encontramos que solo dos aeropuertos en el estado de Sao Paulo son eficientes, mientras que los otros aeropuertos centrales están infrautilizados, con una puntuación de eficiencia inferior al 50%. Los resultados encontrados en este estudio podrian servir como una herramienta importante para las politicas publicas, asi como para las decisiones privadas en el sector aeroportuario. PALABRAS CLAVE: eficiencia aeroportuaria, aeropuertos centrales, análisis envolvente de datos multicriterial.
