The purpose of this paper is to analyze the impact that has had the self-financing model encouraged by the Colombian State on the public nature of the Universidad Nacional de Colombia in the last twenty years, in light of the theory of club goods. From the theoretical and factual analysis, this research reviews the standards of higher education in Colombia in order to explain how the unbalanced increase of private resources and the static public financing of the National University of Colombia, besides some problems in operating costs, has perpetuated the high levels of exclusion in the access to the good, resulting in a restriction of the public nature of the service rendered by this institution in the last two decades.
