Abstract: Understanding efficiency measures in universities allows for informed decision-making on public policies in a country. In this article, we analyze the efficiency of public and private universities, considering that university output is multi-product. To address the multiple outputs, we use radial and hyperbolic distance functions with determinants, estimating the models through stochastic frontiers. The data was obtained from the Spanish Ministry of Science, Innovation, and Universities, considering a panel of data from the years 2016 to 2022, and we analyzed universities in each autonomous community of the country. The aim was to compare the efficiency of public and private universities in each autonomous community, considering outputs such as the number of graduates, national projects, the number of publications, and the average study time for undergraduate degrees. Adequate estimates were obtained on the frontier using the hyperbolic distance function, and when evaluating the efficiency ranking, it was observed that, in general, public universities show higher efficiency; however, in communities where private universities exist, the efficiency of public universities is lower or similar to that of private universities.
