The literature on private higher education has identified striking differences between the public and private sectors in terms of fields of study. For example, unlike their public counterparts, private universities have traditionally specialised in the social sciences and humanities. This paper explores the university market in Argentina to see if these differences still persist today, or if they have blurred over time. This dynamic is studied from the perspective of both supply (the percentage of institutions offering a specific degree programme) and demand (student enrolments). Clearly, both sectors are venturing further and further into each other’s traditional domains.
