O impacto das concessões no setor aeroportuário: comparação do desempenho econômico entre aeroportos brasileiros

airports through concessions contracts brings with it changes in the control structure and informational asymmetries such as those mentioned in the Agency Theory, as well as the agreement of long-term contracts that, according to the Theory of Incomplete Contracts, may present gaps and affect the economic performance of these assets. This article aims to compare the performance indicators of Brazilian airports managed by the government with those found in airports conceded to private entities. For this, quantile regression models were used. The sample consists of the 20 largest Brazilian airports, 14 under public administration and 6 under private administration. The results point to better profitability and cost efficiency at public airports, while private airports perform better in terms of their ability to generate revenues and to diversify the sources of those revenues.
