The study also analyzed the agencies’ budgets, based on amounts obtained and specifically allocated to their funding versus sums actually released by the National Treasury. The authors concluded that the majority of directors come from senior positions within their agency or from other federal government bodies, and that the executive branch uses different strategies to maintain its influence over decision-making. The authors also identified a deterioration over time in the levels of qualifications of directors in the transportation sector. This has been happening for at least eight years. It began in 2008 at ANAC, while in the case of ANTT, this process has been present since its creation. Another noteworthy result is that it is a common practice for the National Treasury not to transfer the complete amount of resources assigned for these agencies, and to freeze some of the resources instead. This study therefore lays the groundwork for a legislative reform aimed at professionalizing the process of approving appointments of directors to federal regulatory agencies, by instituting objective criteria for nominations. In line with this professionalization, the authors propose giving the agencies greater financial autonomy and guarantees related to the exercise of their functions.
